Answer:

Therefore, the coordinates of the vertices of ΔA'B'C' after the dilation with a scale factor of 2.5.

A'(-5, -2.5)B'(2.5, 5)C'(5, -10)

Step-by-step explanation:

Given the vertices of ΔABC

A(-2, -1)B(1, 2)C(2, -4)

Given that ΔA'B'C' is a dilation of ΔABC with a scale factor of 2.5 and the center of dilation (0, 0).

We know that when the scale factor > 1, then the image is enlarged.

The formula to determine the dilation with a scale factor of 2.5.

P(x, y) → P'(2.5x, 2.5y)

Here, P' is the image of P, and the vertices of the image is dilated by a scale factor of 2.5.

In other words, the vertices of the image can be obtained by multiplying the vertices of the original triangle with 2.5.

Thus,

P(x, y) → P'(2.5x, 2.5y)

A(-2, -1) → P'(2.5(-2), 2.5(-1)) = A'(-5, -2.5)

B(1, 2) → B'(2.5(1), 2.5(2)) = B'(2.5, 5)

C(2, -4) → C'(2.5(2), 2.5(-4)) = C'(5, -10)

Therefore, the coordinates of the vertices of ΔA'B'C' after the dilation with a scale factor of 2.5.

A'(-5, -2.5)B'(2.5, 5)C'(5, -10)

Answer:

x>-33/2

Step-by-step explanation:

this is because you must solve the equation. when you divide by a negative number in order to get the x alone the sign of the inequality flips.

Answer:

[tex]x > \frac{ - 11 - 22}{2} [/tex]

Step-by-step explanation:

Step 1: Subtract 7x7x from both sides.

−11<9x+22.−7x

Step 2:Simplify 9x+22.-7x9x+22.−7x to 2x+22.2x+22.

−11<2x+22.

Step 3:Subtract 22.22. from both sides.

−11−22.<2x

Step 4:Divide both sides by 22.

[tex] \frac{ - 11 - 22}{2} < x[/tex]

Step 5, Switch sides.

[tex] x > \frac{ - 11 - 22}{2} [/tex]

Answers

Answer:

y=-3x+5

Step-by-step explanation:

Answer is Y=-3x+5

Answer:

y = -1/2x + 5

Step-by-step explanation:

First, we need to find the slope. Slope is nothing but the height of the triangle over the length of the triangle. Since the height is 5 is the length is 10, the slope should be 5/10. But, since the line is slanting downwards, the slope is negative. So it is -5/10, or -1/2 when simplified. Next, we need to find the y intercept. Y intercept is nothing but where the line crosses the y axis, so the y intercept should be 5. The slope intercept is y = mx+b, where m is the slope and y intercept is b, so our equation should be y = -1/2x + 5.

The reason that we are not counting the individual squares is because they already labeled the graph. So, we have to count accordingly.

The answer you should get is 33/20 or 1.65. How you get this answer is you start by removing the parentheses, then calculate the difference.

2 + (-7/20)

2 - 7/20

20 times 2 equals 40

Subtract 7 from 40

Keep your denominator the same and change your numerator to 33.
