Answer:
D. Dilate rectangle A by a scale factor of 3 with the center of dilation at the origin and rotate it 90° clockwise about the origin.
Step-by-step explanation:
The coordinates of triangle A are (-2,1) , (1,1), (1,-1) and (-2, -1) while that of triangle B are (-3, 6), (3, 6), (3, -3) and (-3, 3).
To transform A to be we need a combination of two transformations, and that is dilation and rotation.
If A is dilated by a scale factor three through the origin as the center of dilation and then rotated through 90° clockwise with the origin as the center of origin, then rectangle B will be obtained.

Step-by-step explanation:
285 + 617 = 902
902 - 620 = 282
Answer: 282
Answer:
k = 13
Step-by-step explanation:
Given
= 4
Multiply both sides by 3.25 to clear the fraction
k = 4 × 3.25 = 13
Answer:
In math terms that means:

If we cross multiply we got:

And solving for x we got:


Step-by-step explanation:
For this problem we can set x a the value of interest and we need to do this: If a number is added to the numerator of 3/7 and the same number is subtracted from the denominator, the result is 4. Let x represent the unknown number.
In math terms that means:

If we cross multiply we got:

And solving for x we got:
