Answer:

Step-by-step explanation:
Given
The attached circle
Required
Find the measure of x
From the attached image:
and
form a semi-circle
So:

Collect like terms


Solve for x


The answer would be D. (2,2)
Since the scale factor is 1/2, all you have to do is multiply 1/2 by each of x-coordinate and y-coordinate of Q.
Multiplying by 1/2 is the same as dividing by 2, so you divide the x and y coordinates of Q to get the dilation image of Q as (2,2).
The answer to your question is 260
Answer: 0.5 and 0.25
Step-by-step explanation: You have to divide the number by 2 to get to the next term.
Answer: y=-5/2x-4
Step-by-step explanation: Use the slope formula and slope-intercept form y=mx+b to find the equation.
