Answer:
-5 and 3
Step-by-step explanation:
you do thos so you can eliminate x and solve for y then substitute the answer to y in one of the equations to solve the equation
Answer:
722.57cm²
Step-by-step explanation:
Below, we have listed six basic equations that can be used to derive the explicit formulas of radius of a cylinder:
Volume of a cylinder: V = π * r² * h ,
Base surface area of a cylinder: A_b = 2 * π * r² ,
Lateral surface area of a cylinder: A_l = 2 * π * r * h ,
Total surface area of a cylinder: A = A_b + A_l ,
Surface Area of Cylinders. To find the surface area of a cylinder add the surface area of each end plus the surface area of the side. Each end is a circle so the surface area of each end is π * r2, where r is the radius of the end. There are two ends so their combinded surface area is 2 π * r2.
The formula for the volume of a cylinder is V=Bh or V=πr2h . The radius of the cylinder is 8 cm and the height is 15 cm. Substitute 8 for r and 15 for h in the formula V=πr2h . ... Therefore, the volume of the cylinder is about 3016 cubic centimeters.

Answer:
C. 60°
Step-by-step explanation:
Add the two given angles and subtract from 180°
ANSWER: X=2
4|2x-2|+10 = 34
4(2x+2)+10 = 34
8x+8+10 = 34
8x+18 = 34
-18 -18
8x = 16
➖ ➖
8 8
X = 2
Steps
1. -2 becomes +2 because of absolute value
2. Distribute the 4
3. Combine like terms
4. Subtract 18 from both sides
5. Divide both sides by 8 to get x alone
