The problem gives you X, so replace X witht he given vaule and solve for y:
y = -0.1x^2 + 4X
X = 40
y = -0.1(40)^2 +4(40)
y = -0.1(1600) + 160
y = -160 + 160
y = 0
The difference between (3x+6y)(3x+6y) and (4x+9y)(4x+9y) is 7x² +36xy+45y²
<h3>What is an Expression ?</h3>
An expression is a mathematical statement which has variables , constants and mathematical operators simultaneously.
The expression given in the question is
(3x+6y)(3x+6y) and (4x+9y)(4x+9y)
the difference when (3x+6y)(3x+6y) is subtracted from (4x+9y)(4x+9y)
(4x+9y)(4x+9y) - (3x+6y)(3x+6y)
16 x² + 36xy+36xy +81y²-9x²-18x -18x -36y²
7x² +36xy+45y²
Therefore in simplest term , The difference between (3x+6y)(3x+6y) and (4x+9y)(4x+9y) is 7x² +36xy+45y²

The upper quartile is the numbers after the median and the lower is the numbers before the median. you find the median of each quartile
Answer:
(goh) (4) = 7
Step-by-step explanation:
(goh) (x) = g(h(x))
Plug in
g(h(x)) = 5(√x) - 3
if x = 4 then
g(h(4)) = 5(√4) - 3
g(h(4)) = 5(2) - 3
g(h(4)) = 10 - 3
g(h(4)) = 7
Answer:
0.25
Step-by-step explanation:
5x-3 > 15x-11/2
5x-15x > 3-11/2
-10x > -2.5
x > -2.5/-10
x > 0.25
