Answer:
Step-by-step explanation:
The first (and only step) is to remove the brackets.
-1/2 * - 3y = 3/2y Two minus make a plus
-1/2 * 10 = - 5
Answer: 3/2 y - 5
To find the constant variation, solve for only one hour (in this case).
Divide 100 with 2
100/2 = 50/1
Each hour is 50 miles driven, so your constant variation is 50 mph
So for this, you'll be using the pythagorean theorem to solve for the height.

Solve the exponents to get

Subtract 81 on each side to get

Square root each side, and your answer should be

or 13.23 ft
Answer:
last one
Step-by-step explanation:
You are swinging A(-1,-2) around the center which in this case is the origin. Keep in mind that points on a circle all have a equal distance from the origin. We don't want the distance from the center to change.
We want the center of that circle to be the origin.
So the answer is the last one:
"Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90° counterclockwise from point A. "

Answer:
65°
Step-by-step explanation:
Any sort of bisector divides a geometry into two congruent parts. Here, we have an angle bisector that divides the larger (130°) angle into two equal parts. The measure of each of the resulting smaller angles will be 130°/2 = 65°.
∠JAE = 65°
