Answer:
(-14,-4)
Step-by-step explanation:
Given the pre-image A=(-7,-2)
If A is dilated with a scale factor of 2
Then the image of A,
A' = (-7,-2) X 2
We multiply each coordinate point by 2
=(-7*2,-2*2)=(-14,-4)
Therefore, the point A' would be: (-14,-4)
Answer:
B, 107°
Step-by-step explanation:
The angle ADC is an inscribed angle and the measure of it is equal to half of the arc it sees which is arc ABC
The measure of arc ABC is 132° + 82° = 214° so the measure of angle <ADC is 214° ÷ 2 = 107°
Answer:
b.
Step-by-step explanation:
The general form for a circle is:
(x - a)^2 + (y - b)^2 = r^2
where (a, b) is the centre and r = the radius.
So here (a, b) = (5, -9) and r = 12 giving:
(x - 5)^2 + (y - (-9))^2 = 12^2
(x - 5)^2 + (y + 9)^2 = 144.
