Answer:
x equals 3 :) if i helped, please give brainliest!
Step-by-step explanation:
Minus 36 from each one you can do it on a calculator:)
To find the rate of change find the difference in the Y values for every X value.
From X 1 to X 3 the Y value changes by -10
-10 / 2 = -5.
The rate of change is -5.
The initial value is when X = 0
When X is 1, the Y value is 20, using the rate of change of -5, this means when X is 0, the Y value would be 25.
The answer would be, the initial value is 25, rate of change is -5
Answer:
or 2.738
Step-by-step explanation:
Let’s just look at the triangle on the top with the
on the top and x on the bottom. (Basically the top half to the equilateral triangle)
There is a small square in the bottom right corner, which indicates that this triangle is a right triangle. This means that we can use the Pythagorean Theorem: 
We know that \sqrt{10} is our hypotenuse, and therefore our c in our equation. Let’s say that x=a in our equation. Therefore we are left to find b. However, b is half the length of the side of the original equilateral triangle. An equilateral triangle means that all three sides are the same length. Therefore our side would also be \sqrt{10} units long. However we know that b is half of that value, so b=
or 
Plugging these values into the equation:
x^2+ (\frac{\sqrt{10} }{2})^{2}=\sqrt{10} ^{2}




This approximately equals 2.738
