Complete the equation of the line through (3,-8) and (6,-4).
Use exact numbers.
Answer:
y = 4/3x - 12
Step-by-step explanation:
Use Point Slope Form: (y - y1) = m(x - x1)
Step 1: Find the slope
m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
m = [tex]\frac{-4 - (-8)}{6 - 3}[/tex]
m = [tex]\frac{-4 + 8}{3}[/tex]
m = [tex]\frac{4}{3}[/tex]
Step 2: Plug into point slope form
(y - (-4)) = 4/3(x - 6)
y + 4 = 4/3x - 24/3
y + 4 - 4 = 4/3x - 8 - 4
y = 4/3x - 12
Answer: y = 4/3x - 12

Question 1 (Mandatory) (1 point)
Which method is best used to prove that a figure has a right angle?
a) Using slope formula to show two segments have opposite reciprocal slopes.
Ub Using slope formula to show two segments have the same slope.
C) Using distance formula to show two segments are congruent.
od) Using the midpoint formula to show two segments have the same midpoint.
Answer:
A
Step-by-step explanation:
Right angle means that the two sides that meet to create right angle are "perpendicular".
Two perpendicular lines meet to form the angle of 90 degrees.
In coordinate geometry, how do we prove that two lines are perpendicular??
We show that their slopes are negative reciprocals of each other.
This also tells us that the angle between the two lines are "right angle".
So, we can use slope formula to show two segments have opposite reciprocal slopes, that will tell us that it is a right angle between the two segments.
Option A is right.
Sarah and Kaylee go to the movie theater and purchase refreshments for their friends.
Sarah spends a total of $47.00 on 12 drinks and 1 bag of popcorn.
Kaylee spends a total of $81.75 on 3 drinks and 9 bags of popcorn.
Write a system of equations that can be used to find the price of one drink and the price of one bag of popcorn.
Using these equations, determine and state the price of a drink, to the nearest cent.
Each drink costs $3.25 and each popcorn costs $8.
Step-by-step explanation:
Step 1:
Assume each drink costs x dollars and each popcorn costs y dollars.
From the given data, we can write the following equations;
[tex]12x + y = 47[/tex], take this as equation 1,
[tex]3x+9y=81.75[/tex], take this as equation 2.
Step 2:
We multiply equation 2 with 4 so we can cancel out the variable x in both equations. By doing this we get
[tex]3x+9y = 81.75[/tex], take this as equation 3. When we subtract 3 from 1, the x variable is canceled out and y can be calculated.
[tex]-35y = -280, y = \frac{280}{35} = 8[/tex]
Step 3:
Substituting this value of y in any of the previous equations we will get x's value.
Here this value of y is substituted in equation 1.
[tex]12x+8 = 47, 12x= 39[/tex],
[tex]x=\frac{39}{12} = 3.25[/tex]
So we have x = $3.25 and y = $8. So each drink costs $3.25 and each popcorn costs $8.

solve by using distributive property: 12x - 6y = 12 and x = -2y +11
Answer:
x = [tex]\frac{1}{11}[/tex]; y = [tex]\frac{-60}{11}[/tex]
Step-by-step explanation:
x = -2y + 11 so x + 2y = 11 (1)
12x - 6y = 12 so 6x - y = 6 (2)
(1) - 2(2) ↔ (x + 2y) - 2(6x - y) = 11 - 2(6)
↔ - 11x = - 1
↔ x = [tex]\frac{1}{11}[/tex]
(2) ↔ y = 6x - 6 = 6([tex]\frac{1}{11}[/tex]) - 6 = [tex]\frac{6}{11}[/tex] - 6 = [tex]\frac{-60}{11}[/tex]

Part A:
A garden is in the shape of a circle with a radius of 10 feet. Edging is placed around the garden
How much edging, in feet, is needed to go around the garden? Round to the nearest whole number?
Part B:
Another garden is in the shape of a semicircle with a radius of 25 feet. Edging is placed around this garden.
How much edging, in feet, is needed to go around this garden? Round to the nearest whole number.
Answer:
Part A = 64 feet
Part B = 79 feet
Step-by-step explanation:
Part A
10 × 2 = 20 = Diameter
Formula is C = π × diameter
20 × π = 62.8318530718 feet = 64 feet
Part B
25 × 2 = 50
Same formula
50 × π = 157.079632679 feet
157.079632679 ÷ 2 = 78.5398163395 feet = 79 feet
divide by 2 because it is a semi circle
Hope his helped :)
For the circular garden with a radius of 10 feet, 63 feet of edging is required. For the semicircular garden with a radius of 25 feet, 129 feet of edging is needed. These figures are obtained by calculating the circumference of a circle and a semicircle, then rounding to the nearest whole number.
Explanation:To find out how much edging is needed for the gardens, we need to calculate the circumference of the circles.
Part A
The formula for the circumference of a circle (which is the distance around the edge) is 2πr, where π (pi) is approximately 3.14, and r is the radius. For a circle with a radius of 10 feet, the circumference is:
2 × 3.14 × 10 feet = 62.8 feet
Rounded to the nearest whole number, we need 63 feet of edging for the garden.
Part B
For a semicircle with a radius of 25 feet, the circumference is half that of a whole circle, plus the diameter (which is 2 × radius). So, first calculate the circumference of the whole circle and then divide by 2 and add the diameter:
(2 × 3.14 × 25 feet) / 2 + 2 × 25 feet = 78.5 feet + 50 feet = 128.5 feet
Rounded to the nearest whole number, we need 129 feet of edging for the semicircular garden.

Hillary and Charlene both drove from City A to City B. At 10 a.m., Hillary left City A and drove at an average speed of 120 km/h. Charlene drove at an average speed of 144 km/h and took 50 minutes. She arrived at City B at the same time as Hillary. Find the time Charlene left City A.
Let's denote the time Charlene left City A as [tex]\( t \).[/tex]
Since Charlene took 50 minutes (or [tex]\(\frac{50}{60} = \frac{5}{6}\) hours)[/tex] to reach City B, and she arrived at the same time as Hillary, we can set up the equation based on the distances traveled by both:
For Hillary:
[tex]\[ \text{Distance}_\text{Hillary} = \text{Speed}_\text{Hillary} \times \text{Time}_\text{Hillary} \]\[ \text{Distance}_\text{Hillary} = 120 \times (t + 1) \][/tex]
For Charlene:
[tex]\[ \text{Distance}_\text{Charlene} = \text{Speed}_\text{Charlene} \times \text{Time}_\text{Charlene} \]\[ \text{Distance}_\text{Charlene} = 144 \times \left(t + \frac{5}{6}\right) \][/tex]
Since they traveled the same distance, we can equate these two expressions:
[tex]\[ 120 \times (t + 1) = 144 \times \left(t + \frac{5}{6}\right) \][/tex]
Now, solve for \( t \):
[tex]\[ 120t + 120 = 144t + 120 \]\[ 24t = 120 \]\[ t = 5 \][/tex]
So, Charlene left City A at 5:00 a.m.

how can you find the differnt between points
Answer:
subtract one from the other
Step-by-step explanation:
You find the difference between points the same way you find any difference: you subtract one from the other.
Points are generally described by an ordered pair. When you subtract one point from the other, you subtract corresponding parts of the ordered pair:
(a, b) - (c, d) = (a-c, b-d)
__
Sometimes, when you're interested in finding the difference between points (x, y), you want to do something different with the y-difference than you do with the x-difference.
For example, the slope of a line is calculated as the ratio of the y-difference to the x-difference. The length of a line segment is the root of the sum of the squares of the differences.
A store that sells merchandise on a college campus is restocking their inventory of sweatshirts and t-shirts. They order a total of 934 items. Each sweatshirt costs $8.00 and each t-shirt costs $5.00. They spend a total of $5,933.00.
A system of equations is written to represent this scenario, where s represents the number of sweatshirts ordered and t represents the number of t-shirts ordered.
{s+t=934
{8s+5+=5933
The solution to the system is (421, 513). Interpret this solution in the context of the situation.
A. The store ordered 513 sweatshirts and 421 t-shirts.
B. The store ordered 421 sweatshirts and 513 t-shirts.
C. The store spent $513.00 on sweatshirts and $421.00 on t-shirts.
D. The store spent $421.00 on sweatshirts and $513.00 on t-shirts.
Answer:
Option B.
Step-by-step explanation:
A system of equations is written to represent this scenario, where s represents the number of sweatshirts ordered and t represents the number of t-shirts ordered.
s + t = 934
8s + 5t = 5,933
The solution to the system is (421, 513).
So, The number of sweatshirts = 421
And the number of t-shirts = 513
Because 8 * 421 + 5 * 513 = $5,933
We will check the options:
A. The store ordered 513 sweatshirts and 421 t-shirts. ⇒Wrong
B. The store ordered 421 sweatshirts and 513 t-shirts. ⇒True
C. The store spent $513.00 on sweatshirts and $421.00 on t-shirts. ⇒Wrong
Because the solution represents the number of sweatshirts and t-shirts.
D. The store spent $421.00 on sweatshirts and $513.00 on t-shirts. ⇒Wrong
Because the solution represents the number of sweatshirts and t-shirts.
So, the answer is option B.
Kate bought $23.40 worth of two types of bird seed. Thistle bird seed sells for $1.60 per pound
and wild bird seed sells for $0.95 per pound. If she bought 12 pounds of wild bird seed, write
and solve a linear equation to find the amount of thistle bird seed she purchased
Answer:
The amount of thistle bird seed she purchased was 7.5 pounds
Step-by-step explanation:
Let
x ----> the amount in pounds of thistle bird seed she purchased
x ----> the amount in pounds of wild bird seed she purchased
we know that
Kate bought $23.40 worth of two types of bird seed.
so
[tex]1.60x+0.95y=23.40[/tex] ----> equation A
She bought 12 pounds of wild bird seed
so
[tex]y=12\ pounds[/tex]
substitute the value of y in the equation A
[tex]1.60x+0.95(12)=23.40[/tex]
solve for x
[tex]1.60x=23.40-11.40\\1.60x=12\\x=7.5\ pounds[/tex]
therefore
The amount of thistle bird seed she purchased was 7.5 pounds
Kate bought 7.5 pounds of thistle bird seed.
Since Kate bought $ 23.40 worth of two types of bird seed, thistle bird seed sells for $ 1.60 per pound and wild bird seed sells for $ 0.95 per pound, if she bought 12 pounds of wild bird seed, to find the amount of thistle bird seed she purchased, the following calculation must be performed, through a linear function:
(12 x 0.95) + 1.60X = 23.40 11.40 + 1.60X = 23.40 1.60X = 23.4 - 11.4 X = 12 / 1.60 X = 7.5
Therefore, Kate bought 7.5 pounds of thistle bird seed.

Write an equation in slope intercept form for the line that has a slope of 12 and passes through the point (3,20)
Answer:
y= 12x-16
Step-by-step explanation:
Given that you have a slope of 12 and a point of (3, 20), you are most obligated to using the Slope-Intercept form, or y=mx+b.
What this allows you to find is the y-intercept if your line has one. You take your point, (3,20), and you insert the values at the appropriate places. You should now have 20=12(3)+b. You will then solve for b by multiplying 12 and 3 to get 36 and subtract that from both sides of the equal sign. You should have 20-36=b. 20-36 is -16, which is your y-intercept.
Now you know all your needed values, you would write the Slope-Intercept form without the values for y and x, to represent your equation.
Since 12 is your slope, it will be 'm' and -16 will be 'b'.
You will end with y = 12x - 16.
Given:
Line passing through,
[tex](x_1,y_1) = (3, 20)[/tex]Slope,
[tex]m = 12[/tex]The equation will be:
→ [tex]y - y_1 = m(x-x_1)[/tex]
By substituting the values,
→ [tex]y-20=12(x-3)[/tex]
→ [tex]y-20=12x-36[/tex]
[tex]y = 12x-16[/tex]

13 green skittles in a bag
with 65 skittles. What is the
ratio of green to total
skittles?
Final answer:
To find the ratio of green to total skittles, divide the number of green skittles by the total number of skittles and simplify the fraction. The ratio of green to total skittles is 1:5.
Explanation:
To find the ratio of green to total skittles, we need to divide the number of green skittles by the total number of skittles and simplify the fraction.
Ratio = Number of green skittles / Total number of skittles
Ratio = 13 / 65
Since 13 and 65 are both divisible by 13, we can simplify the fraction to:
Ratio = 1 / 5
Therefore, the ratio of green to total skittles is 1:5.
