Answer:
A) X = -5, Y = 1
B) X = -2, Y = 4
C) X = -5 , Y = 4
Step-by-step explanation:
The reflection over an x-axis means the values associated with the x remains same while y-axis variable change their sign.
The three co-ordinates of this figure are
A) X = -5, Y = -1
B) X = -2, Y = -4
C) X = -5 , Y = -4
Now going by the above rule to determine the co-ordinates when the image is reflected over x-axis, the new co-ordinates are:
A) X = -5, Y = 1
B) X = -2, Y = 4
C) X = -5 , Y = 4
Step-by-step explanation:
Please find the attachment.
We have been given an image on coordinate plane and we are asked to reflect our given image over the x-axis.
The rule for reflection for an image over x axis is: [tex](x,y)\rightarrow(x,-y)[/tex]. This means that after reflection about x axis, x coordinates remain same but y-coordinates are transformed into their opposite sign.
Let us give names to vertices of our pre-image. A(-5,-1), B(-5,-4) and C(-2,-4).
When we will reflect our pre-image (ABC) about x-axis, x coordinates will remain same, so x coordinates will remain negative.
Since y-coordinates will change into their opposite sign, so coordinates of y will be positive for our image as y-coordinates of pre-image are negative.
A A'
(-5,-1) (-5,1)
B B'
(-5,-4) (-5,4)
C C'
(-2,-4) (-2,4)
Therefore, coordinates of our image A'B'C' will be: A'(-5,1), B'(-5,4) and C'(-2,4).

What is the equation of the graph below?
Answers
Answer:
Step-by-step explanation:
Y=cos(x+r/2)
Answer:
[tex]y=cos(x+\pi )[/tex]
Step-by-step explanation:
From the graph, we can see that y = -1 when x = 0.
So to check whether which of the given options is the equation of the given graph, we will set our calculator to the radian mode and then plug the value of x as 0.
1. y = cos(x + pi/2) = cos(0 + pi/2) = 0
2. y = cos(x+2pi) = cos(0+2pi) = 1
3. y = cos(x+pi/3) = cos(0+pi/3) = 1/2 = 0.5
4. y = cos(x+pi) = cos(0+pi) = -1
Therefore, the equation of this graph is y = cos(x+pi) = cos(0+pi) = -1.
plz help Pru, Piper, and Phoebe share spices in the ratio 5:3:4. If Pru has 24 more spices than Piper, how many spices does Phoebe have?
Answers
Answer:
Step-by-step explanation: Pru, Piper, Phoebe their ratio 5:3:4 added = 12
What this would mean is that Pru has 5/12 of the total amount, Piper has 3/12 of the total, and Phoebe has 4/12 of the total amount of spices all together.
pru = piper + 24
5/12x = 3/12x + 24
5/12x - 3/12x = 24
2/12x = 24
x = 24 / (1/6)
x = 24 * 6
x = 144 spices in all.
Pru has : 5/12(144) = 720/12 = 60 spices
Piper has : 3/12(144) = 432/12 = 36 spices
Phoebe has : 4/12(144) = 576/12 = 48 spices <====
Answer:
48 spices
Step-by-step explanation:
The number of spices each has is a multiple of 5, 3, and 4.
The number of spices each has is 5x, 3x, and 4x.
Pru has 5x spices.
Piper has 3x spices.
Pru has 24 more spices than Piper, so
5x = 3x + 24
2x = 24
x = 12
Phoebe has 4x spices, so Phoebe has

The sum of two numbers is 59 and the difference is 3. What are the numbers?
Answers
Answer:
31 and 28
Step-by-step explanation:
Let x represent the first number.
Let y represent the second number.
x + y = 59
x - y = 3
Use substitution method to solve.
x = y + 3
y + 3 + y = 59
2y + 3 = 59
Subtract both sides by 3.
2y = 56
Divide both sides by 2.
y = 28
Let's find the second number.
59 - 28 = 31
Check
31 -28 = 3
Answer The two numbers are 28 and 31.
The numbers are 31 and 28.
To find the two numbers where the sum is 59 and the difference is 3, we can set up two equations based on the information given.
Let the two numbers be x and y, where x > y. The equations would be:
x + y = 59 (Equation for the sum)x - y = 3 (Equation for the difference)Adding these two equations eliminates y, giving us:
2x = 62
Divide both sides by 2 to find x:
x = 31
Now substitute x back into one of the original equations to find y:
31 + y = 59
Subtract 31 from both sides:
y = 59 - 31
y = 28
Therefore, the two numbers are 31 and 28.

∠1 and ∠3 are supplementary angles, therefore m∠1 + m∠3 = 108°.
m∠1 = 10x + 4, m∠2 = m∠3 = 4x - 6. Therefore we have the equation:
(10x + 4) + (4x - 6) = 180
(10x + 4x) + (4 - 6) = 180
14x - 2 = 180 add 2 to both sides
14x = 182 divide both sides by 14
x = 13
10x + 4 = 10(13) + 4 = 130 + 4 = 134

Answer: x=2 or x=-12

Final answer:
A formula to determine Seth's weekly lunch expense is Weekly Spending = n × 5, where n represents the new price of lunch and the multiplication by 5 accounts for each day of the school week.
Explanation:
To help Seth determine how much he'll now spend on lunch every week, we need to create a formula that takes into account the new price of a lunch and the frequency of his purchases. Let's assume the new price of a lunch is represented by the variable n. Since Seth buys lunch 5 days a week, the formula to calculate his weekly spending will be Weekly Spending = n × 5. This formula can be used to multiply the new price of a lunch (n) by 5, giving Seth the total amount he will spend each week on school lunches.

write in equation in slope intercept form for the line perpendicular to y=-3x+9 that passes through the line 9,9
Answers
Answer:
y = 3x - 18
Step-by-step explanation:
The given line, y = -3x + 9, has slope -3. Any new line perpendicular to this has slope +3/1, or just 3.
Start with the general slope-intercept form of the equation of a straight line:
y = mx + b. Now substitute 9 for y, 9 for x and 3 for m:
9 = 3(9) + b. Then b = -18, and the desired equation is y = 3x - 18.
The equation of the line perpendicular to y = -3x + 9 that passes through the point (9,9) is y = ([tex]\frac{1}{3}[/tex])x + 6.
The question is asking to find the equation of a line in slope-intercept form that is perpendicular to the given line y = -3x + 9 and passes through the point (9,9). To find the equation of a line that is perpendicular to the given line, we need to determine the slope of the new line. The slope of any line perpendicular to a line with a slope of m is [tex]-\frac{1}{m}[/tex]. Since the given line has a slope of -3, the slope of the perpendicular line will be [tex]\frac{1}{3}[/tex]. Now using the point-slope form of a line, which is y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line and m is the slope, we can write the equation of the new line through the point (9,9) as y - 9 = ([tex]\frac{1}{3}[/tex])(x - 9). Simplifying this equation gives us y = ([tex]\frac{1}{3}[/tex])x + 6, which is in slope-intercept form y = mx + b where m is the slope and b is the y-intercept of the line.

The radius of the circle shown below is 7 inches what is the approximate length of AB?
Answers
Answer:
16.5 inches
Step-by-step explanation:
WE have arc length formula for a circle as
Arc length = [tex]\frac{x}{360} (2\pi r)[/tex]
where x is the central angle the arc subtends at the centre.
Here x = 135
r= 7 inches
Hence arc length
=[tex]\frac{135}{360} (2\pi )(7) =16.5"[/tex]
Hence option B
16.5 inches is right answer for arc length for a circle of radius 7 inches.
The measure of length of arc AB is 16.5 inches. Therefore, option B is the correct answer.
What is the relationship between a central angle and its arc?An arc of a circle is a section of the circumference of the circle between two radii. A central angle of a circle is an angle between two radii with the vertex at the centre. The central angle of an arc is the central angle subtended by the arc. The measure of an arc is the measure of its central angle.
Given that, the radius of the circle is 7 inches and measure of arc AB is 135°.
Let O be the center of circle.
So, ∠AOB=135°
We know that, arc length of circle is θ/360° ×2πr
= 135°/360° ×2×3.14×7
= 0.375×2×3.14×7
= 16.485
≈ 16.5 inches
Therefore, the approximate length of AB is 16.5 inches.

The points (-3,4) and (5,-2) are on the graph of function f. If function g is the inverse of function f, what pair of points are on function g?
Answers
The pair of points on the inverse function g, given that (-3,4) and (5,-2) are on function f, are (4,-3) and (-2,5), obtained by swapping the x and y coordinates of the original points.
Explanation:To determine which pair of points are on function g, which is the inverse of function f, we swap the x and y coordinates of the given points on function f. The points (-3,4) and (5,-2) are on function f, so the corresponding points on the inverse function g would be (4,-3) and (-2,5), respectively. In the context of functions and their inverses, the dependence of y on x in one function becomes the dependence of x on y in the inverse function. This flipping of coordinates is an essential property of inverse functions and can be visualized by reflecting across the line y = x on a graph.

what is the equation of this line is standard form (-4,-1) and (1/2,3)
A:8x-9y=-23
B:9x-8y=23
C:8x-9y=23
D:8x-7y=-25
Answers
Answer:
A. 8x - 9y = -23
Step-by-step explanation:
(-4,-1) and (1/2,3)
We write the equation in slope intercept form y=mx+b
then we convert it into standard form
m is the slope and b is the y intercept
[tex]slope = \frac{y_2-y_1}{x_2-x_1}[/tex]
(-4,-1) and (1/2,3)
[tex]slope = \frac{3-(-1)}{\frac{1}{2}-(-4)}[/tex]
[tex]slope = \frac{4}{\frac{1}{2}+4}[/tex]
[tex]slope = \frac{4}{\frac{9}{2}}[/tex]
[tex]slope = 4*\frac{2}{9}[/tex]
[tex]slope m =\frac{8}{9}[/tex]
To find out b we plug in (-4,-1) and slope m value in y = mx+b
-1 = (8/9) (-4) + b
[tex]-1 = -\frac{32}{9} +b[/tex]
Add 32/9 on both sides
[tex]-1+\frac{32}{9} = b[/tex]
Take common denominator 9
[tex]\frac{-9+32}{9} = b[/tex]
[tex]\frac{23}{9} = b[/tex]
So equation y = mx + b becomes
[tex]y= \frac{8x}{9} + \frac{23}{9}[/tex]
Standard form is Ax + By = C
To get standard form , multiply the whole equation by 9
9y = 8x + 23
Subtract 8x on both sides
