Find an equation of the line. Write the equation using function notation.
Through (3,-3); perpendicular to 4y=x-8
The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:
[tex]y = -4x+9[/tex]
Step-by-step explanation:
Given equation of line is:
[tex]4y=x-8[/tex]
We have to convert the given line in slope-intercept form to find the slope of the line
So,
Dividing both sides by 4
[tex]\frac{4y}{4} =\frac{x-8}{4}\\y = \frac{1}{4}x-\frac{8}{4}\\y = \frac{1}{4}x-2[/tex]
Let m1 be the slope of given line
Then
[tex]m_1 = \frac{1}{4}\\[/tex]
Let m2 be the slope of line perpendicular to given line
As we know that produt of slopes of two perpendicular lines is -1
[tex]m_1.m_2 = -1\\\frac{1}{4} . m_2 = -1\\m_2 = -1*4\\m_2 = -4[/tex]
The slope intercept form of line is given by:
[tex]y = m_2x+b[/tex]
Putting the value of slope
[tex]y = -4x+b[/tex]
to find the value of b, putting (3,-3) in equation
[tex]-3 = (-4)(3) + b\\-3 = -12 +b\\b = -3+12\\b = 9[/tex]
Putting the value of b in the equation
[tex]y = -4x+9[/tex]
Hence,
The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:
[tex]y = -4x+9[/tex]

Final answer:
The result is the equation f(x) = -4x + 9 in function notation.
Explanation:
To find the equation of a line that is perpendicular to another and passes through a given point, follow these steps:
First, determine the slope of the given line. The equation given is 4y = x - 8. To put this in slope-intercept form, divide everything by 4 to get y = ⅔x - 2. The slope (m) of this line is ⅔.To find the slope of a line perpendicular to this one, take the negative reciprocal of ⅔, which is -4.Now, using the point-slope form of a line equation, which is y - y1 = m(x - x1) where (x1, y1) = (3, -3) and m = -4, we get:Therefore, the equation of the line in function notation is f(x) = -4x + 9.

Two of the angles in a triangle measure 18° and 72°. What is the measure of the third angle?
Final answer:
To find the third angle of a triangle, add the two known angles and subtract from 180 degrees. In this case, the third angle measures 90 degrees since the sum of the two given angles is 90 degrees.
Explanation:
When determining the measure of the third angle in a triangle, we utilize the fundamental property that the sum of all angles in a triangle equals to 180 degrees. Given that two of the angles measure 18° and 72°, we can find the third angle by subtracting the sum of these two angles from 180°.
The calculation is as follows:
Add the two known angle measures: 18° + 72° = 90°.Subtract this sum from the total sum of angles in a triangle: 180° - 90° = 90°.Therefore, the measure of the third angle in the triangle is 90 degrees.

How to solve -7-8(6x+5)
Answer: -47 - 48x
Step-by-step explanation: When you first take a look at this problem, it's tempting to want to subtract -7 - 8 to get -15 and then distribute the -15 through the parentheses.
You wouldn't want to subtract however before you distribute because the distributive property is a form of multiplication and remember from your order of operations that multiplication comes before subtraction.
So the first thing you want to do here is distribute and change the minus sign in front of the -8 to plus a negative 8 so that you know you are distributing a -8 through your parentheses.
So we have -7 + -8 times 6x which is -42x + -8 times 5 which is -40.
Now we have -7 + -48x + -40.
Now just combine your like terms. -7 + -40 is -47 and plus a negative 48x can be written as -48x so we have -47 - 48x.
So your answer is just -47 - 48x.

Final answer:
Factor completely [tex]6x^2[/tex] - 11x - 10 to find the equivalent binomials involves finding two numbers that multiply to -60 and add to -11. In this case, the numbers are -15 and +4, and using factor by grouping, the correct factorization is (3x + 2)(2x - 5).
Explanation:
When asked to factor the expression [tex]6x^2[/tex] − 11x − 10 completely, we're looking for two binomial expressions that multiply together to produce the original quadratic equation. To do this, we seek two numbers that multiply to give [tex]6x^2[/tex] times -10 (which is -[tex]60x^2[/tex]) and add to give -11x. Factoring is a method to express an equation as a product of its factors.
Let's find two such numbers: -15 and +4. These numbers give a product of -60 and a sum of -11, which fits our criteria. Now we replace the middle term (-11x) with -15x+4x to use factor by grouping.
Original equation: [tex]6x^2[/tex] − 11x − 10
Rewritten with new terms: [tex]6x^2[/tex] − 15x + 4x − 10
Factor by grouping: ([tex]6x^2[/tex] − 15x) + (4x − 10)
Factor out common terms: 3x(2x − 5) + 2(2x − 5)
Factor out the common binomial: (2x − 5)(3x + 2)
The completely factored form of the quadratic equation is (3x + 2)(2x − 5).

26. How much longer is dinner than the
Paulo's family has 1 hour and 45 minutes before the trip to Scenic Lake Park after their arrival at the reunion.
Explanation:The question asks how long Paulo's family has before the trip to Scenic Lake Park if they arrived at a family reunion at 8:30 A.M. and the trip is scheduled to start at 10:15 A.M. To solve this, we need to calculate the time difference between 8:30 A.M. and 10:15 A.M.
Here's how you calculate the time difference:
Start by noting the start time which is 8:30 A.M.The end time is 10:15 A.M.To find the difference, consider how many whole hours are between the times: There is 1 full hour from 8:30 A.M. to 9:30 A.M.Then, we need to account for the remaining time from 9:30 A.M. to 10:15 A.M., which is 45 minutes.Adding the full hour and the remaining 45 minutes, we find that there is a 1 hour and 45 minutes gap between the arrival time and the departure for the trip.

A photographer stands 60 yards from the base of a lighthouse and observes that the angle between the ground and the top of the lighthouse is 41° How tall is the lighthouse?
Answer:
The height of lighthouse is 52.2 yards
Solution:
Given that photographer stands 60 yards from the base of a lighthouse and observes that the angle between the ground and the top of the lighthouse is 41 degree
The diagram is attached below
Consider a right angled triangle ABC
AB is the height of the lighthouse
BC is the distance between the base of a lighthouse and Photographer
As per given, BC = 60 yards
Angle between the ground and the top of the lighthouse is 41 degree
Angle ACB = 41 degree
To find: height of lighthouse i.e AB = ?
We know that,
[tex]tan(\angle ACB) = \frac{Perpendicular}{Base}[/tex]
Here Base is BC and perpendicular is AB
[tex]\tan 41^{\circ}=\frac{A B}{B C}[/tex]
Substituting the values,
[tex]\begin{aligned}&\tan 41^{\circ}=\frac{A B}{60}\\\\&0.8692=\frac{A B}{60}\\\\&A B=0.8692 \times 60=52.157 \approx 52.2\end{aligned}[/tex]
Thus the height of lighthouse is 52.2 yards
Find the value of x and y.
Answer:
Step-by-step explanation:
CD and AB are parallel; DB transverse
∠D + ∠B = 180 {co interior angles}
112 + 27 + y = 180
139 + y = 180
y = 180 - 139
y = 41
In ΔABC,
49 + x + y = 180 ( sum of all angles of triangle}
49 + x + 41 = 180
90 + x = 180
x = 180 - 90
x = 90
What equals the expression if a=2.4 b=0.237 c=9.49. c-2ab
8.3524 equals the expression c - 2ab if a = 2.4 b = 0.237 c = 9.49
Step-by-step explanation:
The given is:
a = 2.4b = 0.237c = 9.49We need to find the value of the expression c - 2ab
∵ The expression is c - 2ab
∵ a = 2.4
∵ b = 0.237
∵ c = 9.49
- Substitute the values of a , b and c in the expression to find its value
∴ 9.49 - 2(2.4)(0.237) = 9.49 - 2(0.5688)
∴ 9.49 - 2(2.4)(0.237) = 9.49 - 1.1376
- Subtract the two numbers
∴ 9.49 - 2(2.4)(0.237) = 8.3524
8.3524 equals the expression c - 2ab if a=2.4 b=0.237 c=9.49

The question asks for equivalent expressions to 3-8/3-4. After clarifying and simplifying the expression, we determined that the equivalent expressions are 3-12 (A) and 13/12 (F).
Explanation:The question is asking us to determine which expressions are equivalent to 3−83−4. First, let's clarify this expression. The symbols − and − can stand for subtraction or negative signs, making the expression ambiguous. However, we can interpret this as a subtraction problem with mixed numbers, which would be processed as 3 minus 8 thirds minus 4. Converting the mixed numbers to improper fractions, we get: 3−(8/3)−4 which simplifies to (9/3)−(8/3)−(12/3). This simplifies to 1/3−(12/3), or 1/3− 4, which then further simplifies to −(⅔).
When we look for equivalent expressions, we have the following options:
A) 3−12 is correct because it is the simplified form of 3 minus 8/3 minus 4, which is −3 1/3.B) 3−4 is incorrect because it simplifies to −1, which is not the same as −3 1/3.C) 3² is incorrect as this represents 3 squared, or 9, which is not the same as −3 1/3.D) 13² is incorrect because it represents 1/3 squared, which is 1/9, not the same as −3 1/3.E) 13´ could be construed as 13 to the power of 4 or 1/3 to the power of 4, but both interpretations are incorrect.F) 13⅜ is correct because it represents 1/3 minus 8/3 minus 4, which is −3 1/3.

Answer:
Cost of a box of brownies = $5
Cost of a loaf of banana bread = $4
Step-by-step explanation:
Let, x= box of brownies.
y=loaf of banana bread.
Now,
Sarah bought 4 boxes of brownies and 6 loaves of banana at $44, after expressing this in equation form we get:-
[tex]4x+6y=44[/tex] --------------------------(equation 1)
And George bought 5 boxes of brownies and 3 loaves of banana at $37, after expressing this in equation form we get:-
[tex]5x+3y=37[/tex] --------------------------(equation 2)
Now,
[tex]4x+6y=44[/tex]
[tex]4x=44-6y[/tex]
[tex]x=\frac{44-6y}{4}[/tex]
[tex]x=11-\frac{6}{4}y[/tex]
[tex]x=11-\frac{3}{2}y[/tex]------------------(equation 3)
Now substituting equation 3 in equation 2 we get,
[tex]5x+3y=37[/tex]
[tex]5(11-\frac{3}{2}y)+3y=37[/tex]
[tex]55-(\frac{15}{2}\times y) +3y=37[/tex]
[tex]55-37=(\frac{15}{2}\times y)-3y[/tex]
[tex]18=7.5y-3y[/tex]
[tex]18=4.5y[/tex]
[tex]y=4[/tex] ----------------------------------(Equation 4)
Now putting value of y from equation 4 in equation 3
i.e. [tex]x=11-\frac{3}{2}y[/tex]
[tex]x=11-\frac{3\times 4}{2}[/tex]
[tex]x=11-6[/tex]
[tex]x=5[/tex]
Therefore the cost of a box of brownies = $5
the cost of a loaf of banana bread = $4

Rita's family is moving to Grand Junction to Dallas. The moving van averages 60 miles each hour. About how many hours does the van take to reach Dallas? Explain your work
Answer:
16 hours and 20 minutes.
Step-by-step explanation:
Please consider the complete question.
Rita's family is moving to Grand Junction to Dallas, which is 980 miles. The moving van averages 60 miles each hour. About how many hours does the van take to reach Dallas?
To find the time taken by van to reach Dallas, we will divide total distance by speed.
[tex]\text{Time}=\frac{\text{Distance}}{\text{Speed}}[/tex]
[tex]\text{Time taken to reach Dallas}=\frac{980\text{ Miles}}{60\frac{\text{ Miles}}{\text{Hour}}}[/tex]
[tex]\text{Time taken to reach Dallas}=\frac{980\text{ Miles}}{60}\times \frac{\text{ Hour}}{\text{Miles}}[/tex]
[tex]\text{Time taken to reach Dallas}=\frac{98}{6}\text{ Hour}[/tex]
[tex]\text{Time taken to reach Dallas}=16.3333\text{ Hour}[/tex]
Let us convert 0.3333 hours into minutes by multiplying 0.3333 by 60.
[tex]0.3333\times 60=19.998\approx 20[/tex]
Therefore, it will take 16 hours and 20 minutes for the van to reach Dallas.
Final answer:
To calculate the time it takes for the van to reach Dallas, divide the distance from Grand Junction to Dallas by the average speed of the van.
Explanation:
To calculate the time it takes for the van to reach Dallas, we need to divide the distance from Grand Junction to Dallas by the average speed of the van.
The distance from Grand Junction to Dallas is not provided in the question, so we cannot calculate the exact time taken. However, if we are given the distance, we can use the formula:
Time = Distance / Speed
For example, if the distance is 300 miles, and the van's average speed is 60 miles per hour, then the time taken would be:
Time = 300 / 60 = 5 hours

$4.16 for 4 pounds of bananas
$16.48 for 8 pounds of potatoes
$18.36 for 2 pizzas
2 cups of flour to make 36 cookies
9.18,1.04,18,2.06
Real word problem ⇒ constant of proportionality
$4.16 for 4 pounds of bananas ⇒ 1.04
$16.48 for 8 pounds of potatoes ⇒ 2.06
$18.36 for 2 pizzas ⇒ 9.18
2 cups of flour to make 36 cookies ⇒ 18
Solution:
A proportional relationship is one in which two quantities vary directly with each other.
We say the variable y varies directly as x,
if for x ∝ y
then, x = y k
Where "k" is called constant of proportionality
[tex]k = \frac{x}{y}[/tex]
$4.16 for 4 pounds of bananas
x = 4.16 and y = 4
[tex]k = \frac{4.16}{4} = 1.04[/tex]
Thus constant of proportionality is 1.04
$16.48 for 8 pounds of potatoes
x = 16.48 and y = 8
[tex]k = \frac{16.48}{8} = 2.06[/tex]
Thus constant of proportionality is 2.06
$18.36 for 2 pizzas
x = 18.36 and y = 2
[tex]k = \frac{18.36}{2} = 9.18[/tex]
Thus constant of proportionality is 9.18
2 cups of flour to make 36 cookies
x = 36 and y = 2
[tex]k = \frac{36}{2} = 18[/tex]
Thus constant of proportionality is 18
