The answer is (4x+3y=4 2x-7=7: 5/2 and y=-2) hope it helps and have a good day!
The volume is length * width * height. Length * width is 4 * 5 or 20, so we have that 20 * height = 200. Divide by 20 to get height = 10.
You need to know:
Tangent function has range of <span>(-∞, ∞)
Sine function has range of [-1,1], which is the same as cosine function
So [-3,3] matches the 1st, [0,2] matches the 2nd, [-1,7] matches the 3rd, the 4th will be the rest </span>
