To find the X-INTERCEPT, substitute in 0 for y and solve for x. To find the Y-INTERCEPT, substitute in a 0 for x and solve for y.

x-intercept: (16,0)
y-intercept:(0,-4)

4y = 9x - 21<br> y = x-4
Anastaziya [24]

Answer:

x = 1

y = -3

Step-by-step explanation:

if y = x - 4

then reorganise the first equation

4 (x - 4) = 9x -21

4x - 16 = 9x - 21

5 = 5x

x = 1

What is the approximate volume of a basketball with the circumference of 42ft ?
Semmy [17]
We know that

[volume of a sphere]=(4/3)*pi*r³

length of a circumference=42 ft
[length of a circumference]=2*pi*r-------> r=[length of a circumference]/(2*pi)
r=[42]/(2*pi)---------> r=6.6845 ft

[volume of a sphere]=(4/3)*pi*6.6845³-----------> 1251.11 ft³

the answer is 1251.11 ft³

Explain why the solution to 3r =2 must be less then 1.
saveliy_v [14]
For this you have to get r by itself so you put 1 over 3 and move it to the other side and then you get 2/3 as an answer

<h2>Answer:</h2>

D. \ 408in^2

<h2>Step-by-step explanation:</h2>

This is a square pyramid because it's a solid having a square base. The point up the pyramid is called the apex and is directly above the middle of the square base. The surface area of a solid is the total area of its outer surface. If we unfold this pyramid, we'll get one square and four identical triangles. So the surface are can be calculated as follows:

s=s_{square}+4s_{triangle}

FOR THE SQUARE:

s_{square}=L^2 \\ \\ L=12in \\ \\ s_{square}=12^2=144in^2

FOR THE TRIANGLE:

s_{triangle}=\frac{bh}{2} \\ \\ b=12in \\ h=11in \\ \\ s_{triangle}=\frac{12\times 11}{2}=66in^2

Finally:

s=s_{square}+4s_{triangle} \\ \\ s=144+4(66) \\ \\ s=144+264 \\ \\ \boxed{s=408in^2}
