Answer: y=3
Subtract the bottom left of the triangle from the number at the top of the triangle. Then that number is multiplied by the number at the bottom right of the triangle.
To solve:
6-5=1
1•3=3
y=3
Answer:
A. 2 (I can't really see the graph clearly, I think this is right)
Step-by-step explanation:
(1,4)(2,6)
6-4 =2
2-1 =1
2/1 =2
B^2 - 4ac
(-9)^2 - 4 (2)(9)
= 81 - 72
=9 >0 yet it is a perfect square (3^2 =9)
So , it is 2 real and rational roots
(x-3) ( 2x-3) =0
x = 3 , x = 3/2
Answer:
3.7
Step-by-step explanation:
Inversely means we are taking the constant and dividing it.
So y varies inversely with x means "y=k/x".
k is a constant. We can find the constant if they give us a point on this curve.
The constant is a number that doesn't change no matter your input and output.
So they actually give us k=8.88 and y=2.4 so let's input this:

We need to solve this equation for x. You can do your favorite thing in cross-multiply. But how, Freckles? Well just slap a 1 underneath that 2.4. You can do that because 2.4/1 is still 2.4.

Cross-multiply:


Divide both sides by 2.4:

when
.
The bottom is (25 x 20) = 500 of whatever those units are, squared. Each long side is (25 x the depth of the pool, which we don't know), and each end is (20 x depth).
