I think a. But I don’t understand this question.
7x - 4y + 8=0 slope intercept is y=mx+b so you have to get y alone
+4y =+4y so add for y on both sides
7x + 8=4y Then divided 4y on both sides
7x/4 8/4= 4y/4
slope intercept form is y=7/4x+2
A - Area
V - Volume
A = 4piR^2
V = 1.33piR^3
With the info given, 289 = 4piR^2, making R = 4.8
Plug this into the volume formula, and you'll get 1.33*pi*(4.8^3), which equates to 463.3 cubic centimeters.
Answer: (-1, -2) or (-2, 1)
Step-by-step explanation:
i graphed it on desmos and used the intersected points.
