Answer:
x = 3, y = - 9
Step-by-step explanation:
5x + 5y = - 30...... (1)
2x - y = 15
-y = 15 - 2x
y = 2x - 15..... (2)
From equations (1) & (2)
5x + 5(2x - 15) = - 30
5x + 10x - 75 = - 30
15x = 75 - 30
15x = 45
x = 45/15
x = 3
Plug x = 3 in equation (2)
y = 2*3 - 15
y = 6 - 15
y = - 9
Therefore,
x = 3, y = - 9
or
(x, y) = (3, - 9)
The answer is 4,615.8 cubic centimeters
The volume of a cylinder is pi*radius^2*height
If pi is 3.14 and you plug in the radius (7cm) and the height (30cm), you get 3.14*7^2*30, which equals 4,615.8 cm cubed
The answer is A.
5(10)+13(14)=232
50 + 182 =232
12(10)+7(14)=218
120 + 98 =218
2/1x or 2x since it rises 2 and runs 1 and it’s going right so it’s positive
