Find all x-intercepts and y-intercepts of the graph of the function.<br> F(x)=x³-4x² - 4x + 16

Lady bird [3.3K]

Answer: (0;16) (4;0) (2;0) (-2;0).

Step-by-step explanation:

Y-intercepts of the graph of the function F(x)=x³-4x² - 4x + 16:

$x=0\\F(x)=0^3-4*0^2-4*0+16\\F(x)=16.\\Hence,\ (0;16).$

X-intercepts of the graph of the function F(x)=x³-4x² - 4x + 16:

$F(x)=0\\0=x^3-4x^2-4x+16\\0=(x^3-4x^2)-(4x+16)\\0=x^2*(x-4)-4*(x-4)\\0=(x-4)*(x^2-4)\\0=(x-4)*(x^2-2^2)\\0=(x-4)*(x-2)*(x+2)\\x-4=0\\x_1=4.\\Hence,\ (4;0)\\x-2=0\\x_2=2.\\Hence,\ (2;0)\\x+2=0\\x_3=-2.\\Hence,\ (-2;0).$

Solve the system of equations.<br> 2x+8y=6<br> -5x-20y+-15

kondor19780726 [428]

Answer:

2x+8y=6

Step 1: Add -8y to both sides.

2x+8y+−8y=6+−8y

2x=−8y+6

Step 2: Divide both sides by 2

$\frac{2x}{2}$ = $\frac{-8y+6}{2}$

x=−4y+3

rosijanka [135]

Answer:

Step-by-step explanation:

Let x be the purchase price

5% of x = $ 174

$\frac{5}{100}*x=174\\\\x=174*\frac{100}{5}\\\\x=174*20\\$

Purchase price = $ 3480
