2x + 3 +2x +3 hhhhhhh

In this situation I think x=1.5 because you combine like terms so 2x+2x=4x and 3+3=6 so after that it’s 4x=6 and 4(1.5)=6

Find the point of the intersection for the given systems y=x^2+1 and y=x+1

mario62 [17]

set them equal to each other

x²+1=x+1

minus 1 from both sides

x²=x

minus x both sides

x²-x=0

factor

x(x-1)=0

set each to 0

x=0

x-1=0

x=1

subsitute back to find y values

y=x+1, y=0+1, y=1, one point is (0,1)

y=x+1, y=1+1, y=2, another point is (1,2)

the 2 points of intersection are (0,1) and (1,2)

Find the volume of the sphere

romanna [79]

V = $\frac{4}{3}$ $\pi$ $r^{3}$ is the formula to find the volume of a sphere.

First cube the radius (12)

$12^{3}$ = 1728

Now multiply 1728 by 4/3 by multiplying it by 4, and then dividing the result by 3.

1728 x 4 = 6912

$\frac{6912}{3}$ = 2304

Now, we multiply this number by $\pi$ to get our final answer.
You typically use 3.14 to approximate $\pi$ .

2304 x 3.14 = 7234.56

Therefore, the volume of a sphere with a radius of 12 will be approximately 7234.56

Hope this helps!!
Let me know if there's anything you don't understand and I'll try to explain as best I can.
