Answer:
y = 4
x = -16
Step-by-step explanation:
this time we should multiply the first equation with -1 because we only need to change its state of negativity
2x + y = -28
-2x - 2y = 24 ➡ -y = -4 ➡ y = 4
if 2x + y = -28 the 2x + 4 =-28 ➡ 2x = -32 x = -16
Answer:
3/5
Step-by-step explanation:
When you are given an x-intercept, the y value will always be 0.
When you are given a y-intercept, the x value will always be 0.
With the intercepts we are given, we can make two points we can solve for the slope with.
(5, 0)
(0, -3)
Now, find the slope with the formula [ y2-y1/x2-x1 ]
-3-0/0-5
-3/-5
3/5 or 0.6
Best of Luck!

Answer:
true
Step-by-step explanation:
Answer
the V of cylinder is V=Pi r² H, si H = V/Pi x r², or r = d/2,
so H=4V/Pi x d²
