What is the answer for -5x^2=-500 by factoring the quadratic equation?
evablogger [386]

Answer:

x=10

Step-by-step explanation:

I think..i tired

 

Divide both sides by 55.

{x}^{2}=-\frac{500}{5}x2=−5500

2

 

Simplify  \frac{500}{5}5500  to  100100.

{x}^{2}=-100x2=−100

3

 

Take the square root of both sides.

x=\pm \sqrt{-100}x=±√−100

4

 

Simplify  \sqrt{-100}√−100  to  \sqrt{100}\imath√100ı.

x=\pm \sqrt{100}\imathx=±√100ı

5

 

Since 10\times 10=10010×10=100, the square root of 100100 is 1010.

A linear function g models a relationship in which the dependent variable decreases 3 units for every 5 units the independent va
Sever21 [200]

Answer:

Slope=-2/3,  y-intercept=2, x-intercept=3

Step-by-step explanation:

Let the independent variable be x and dependent variable be y

y=h(x)

h is a linear function so it is represented in the general form of y=mx+c where

m is slope and c is the y-intercept.

Given "the dependent variable decreases 2 units for every 3 units the independent variable increases."

When x increases by 3, y decreases by 2

So the slope = rate of change of y / rate of change of x = -2/3

Given h(0)=2, h(0)=m(0)+c=2

c=2

Combining slope and y-intercept, y=-2/3*x+2

x-intercept is when y=0

0=-2/3*x+2

2/3*x=2

x=2*3/2=3

x-intercept=3
