Answer:
x= -1/2
Step-by-step explanation:
Answer:
15.1 mm²
Step-by-step explanation:
Lateral surface area of a cylinder = 2πrh
(where r is the radius and h is the height)
Given:
Substitute given values into the formula:
⇒ Lateral surface area = 2π(1.2)(2)
= 4.8π
= 15.1 mm² (nearest tenth)
Ok im not sure the answer yet so ima work on it at the same time while im explaining it. (The answer will probably be near the end)
We can use the elimination method to eliminate y out. To do that we multiply the first equation by 3.
6x+3y=-12
Now just subtract it from the other equation.
6x+3y=-12
5x+3y=-6
***x=-6***
Usually after doing the elimination method you will have to solve for x but in this case its already solved for you. If you want to find y now you just take the first equation and fill x with -6 and solve for y.
2(-6)+y=-4
-12+y=-4
y=8
