This is pretty weird: ax+ b > c is equivalent to ax + b > 0, for instance. c might always be chosen as zero, or b, or any value!

280x <= 348.76, or -280x + 348.76 >= 0,

so a = -280, b = 348.76 and c = 0 is one solution

can someone answer my question????? pls this is already missing i’ll give brainlist and points don’t ignore

Reminder: y = mx + b, to isolate y, you would need to subtract mx value, and what you do to one side, you do to all. If there’s a coefficient in front of your y value, you then divide the equation by that coefficient. Once y is isolated, m and b values are easier to find.

Answer:

1) y = -2x + 1 // m = -2, b = 1

2) y = 5/8x - 1 // m = 5/8, b = -1

3) y = 7/8x - 3/4 // m = 7/8, b = -3/4

4) y = 3/4x + 4 // m = 3/4, b = 4

The volume of a sphere is 3,000 m^3. What is the surface area of the sphere to the nearest square meter?
vovangra [49]

Answer:

C

Step-by-step explanation:

V=4 /3πr3

3000=1 1/3*3.14*r*r*r

3000=4.18666667*r*r*r

716.560509=r^{3}

Cube root the number

8.94851471456=r

TSA=4\pir^{2}

TSA=4*3.14*8.94851471456*8.94851471456

TSA=1006.26

Since we used different numbers for pi and I rounded our answer will be different but the answer is C
