Answer:
X:Y
12:4
Just start with y=1 and work upwards giving x a value of y+8 until x is three times larger than y.
x=y+8 and x=3y
x=y+8
y=x-8
y=12-8
y=4
x=3y
x=3(x-8)
x=3x-24
x-3x=-24
-2x=-24
-2x/-2=-24/-2
x=12

Answer:
Slope = -3
y-intercept = (0,-4)
Equation: y = -3x-4
Step-by-step explanation:
We can take any two input-output pairs from the table to find the equation of given function.
Linear function is given by:
[tex]y =mx+b[/tex]
Here m is the gradient of the functions which is defined as:
[tex]m = \frac{rise}{run} = \frac{y_2-y_1}{x_2-x_1}[/tex]
The input-output pairs are:
(x1,y1) = (-1,-1)
(x2,y2) = (0,-4)
First of all,
[tex]m = \frac{-4-(-1)}{0-(-1)}\\= \frac{-4+1}{1} = -3[/tex]
Putting the value of slope in the equation
[tex]y = -3x+b[/tex]
Putting (-1,-1) in the equation
[tex]-1 = -3(-1)+b\\-1 = 3+b\\b = -1-3\\b = -4[/tex]
The equation will be:
[tex]y = -3x-4[/tex]
Hence,
Slope = -3
y-intercept = (0,-4)
Equation: y = -3x-4

If a dilation is applied to a triangle, then the image must be _____.
a congruent triangle.
a triangle that is flipped over a line of symmetry.
a triangle that is rotated about a given point.
a larger or smaller triangle.
Answers
Answer:
a triangle that is rotated about a given point.
Step-by-step explanation:
Answer:
If a dilation is applied to a triangle, then the image must be similar.
Step-by-step explanation:
We have been given an incomplete sentence. We are supposed to fill in the given blank.
Sentence:
If a dilation is applied to a triangle, then the image must be _____.
Since we know that after dilating a figure by a scale factor, the resulting image will be either bigger or smaller than the original figure depending on the scale factor.
If the scale factor is greater than one, so resulting figure will be bigger than the original figure.
If the scale factor is less than one, so resulting figure will be smaller than the original figure.
Since all the angles of a triangle add up-to 180 degrees, so the measure of angles of the resulting figure will be same as the original triangle.
Since the corresponding sides of pre-image and image are proportional, so both triangles will be similar not congruent.

Answer:

Step-by-step explanation:
Let's solve for b.
r=(b−5)(m)
Step 1: Flip the equation.
bm−5m=r
Step 2: Add 5m to both sides.
bm−5m+5m=r+5m
bm=5m+r
Step 3: Divide both sides by m.
bm/m=5m+r/m
b=5m+r/m

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Step 1: Define
Find points on the graph.
Point (1, 1)
Point (-1, -3)
Step 2: Find slope m
Substitute: [tex]m=\frac{-3-1}{-1-1}[/tex]Subtract: [tex]m=\frac{-4}{-2}[/tex]Divide: [tex]m=2[/tex]Step 3: Find y-intercept b
Given: (0, -1) as y-intercept
Step 4: Write linear equation
y = 2x - 1
The equation y = 2x - 1 is the correct representation of the line in slope-intercept form.
The slope-intercept form of a linear equation is given by y = mx + b, where m represents the slope of the line and b represents the y-intercept.
Among the options provided, the equation y = 2x - 1 is already in the slope-intercept form. In this equation, the slope is 2, which means that for every unit increase in x, y increases by 2. The y-intercept is -1, indicating that the line intersects the y-axis at the point (0, -1).
The equations y = -2x - 1, y = 1/2x - 1, and y = 1/2x + 1 are not in slope-intercept form. In the equation y = -2x - 1, the slope is -2 and the y-intercept is -1. In the equation y = 1/2x - 1, the slope is 1/2 and the y-intercept is -1. Lastly, in the equation y = 1/2x + 1, the slope is 1/2 and the y-intercept is 1.
Therefore, the equation y = 2x - 1 is the correct representation of the line in slope-intercept form.
