Answer:
4
- 4x³ + 20x² - 20x
Step-by-step explanation:
(g × f)(x) = g(x) × f(x) = (x³ + 5x)(4x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
x³(4x - 4) + 5x(4x - 4) ← distribute both parenthesis
= 4
- 4x³ + 20x² - 20x
This can also be done using FOIL, that is
(x³ + 5x)(4x - 4)
= 4
- 4x³ + 20x² - 20x
Answer:
the answer is 90 (typing more to reach the limit)
I'm not sure, but I know that it is longer than 5
Simply a right triangle. because two equal lines that lead up to 90 makes a right triangle
Answer:
(a) ![y+1.4=1.9(x-4.5)](https://tex.z-dn.net/?f=y%2B1.4%3D1.9%28x-4.5%29)
(b) ![y-1=2(x+8)](https://tex.z-dn.net/?f=y-1%3D2%28x%2B8%29)
Step-by-step explanation:
If a line passes through a points
with slope m, then the point slope form of the line is
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
It is given that the slope of the line is 1.9 and it passes through the point (4.5, -1.4). So, the equation of line in point-slope form is
![y-(-1.4)=1.9(x-4.5)](https://tex.z-dn.net/?f=y-%28-1.4%29%3D1.9%28x-4.5%29)
![y+1.4=1.9(x-4.5)](https://tex.z-dn.net/?f=y%2B1.4%3D1.9%28x-4.5%29)
It is given that the slope of the line is 2 and it passes through the point (-8,1). So, the equation of line in point-slope form is
![y-1=2(x-(-8))](https://tex.z-dn.net/?f=y-1%3D2%28x-%28-8%29%29)
![y-1=2(x+8)](https://tex.z-dn.net/?f=y-1%3D2%28x%2B8%29)
