Answer:

8x² + 5x - 3

Step-by-step explanation:

Given

(3x² - 2) + (5x² + 5x - 1)

Since both parenthesis are distributed by 1 just remove them, that is

3x² - 2 + 5x² + 5x - 1 ← collect like terms

= (3x² + 5x²) + 5x + (- 2 - 1)

= 8x² + 5x - 3

inessss [21]

Answer:

Step-by-step explanation:

Noon is 12:00

5am to 12noon is 7 hours

6,000 to 6,500

It grew by 500 in 7 hours

So one hour it is 500/7

In 12 hours that is from 12noon to 12midnight it will be 12×500/7+6500 since at 12noon it was 6500 that will be 6500+857=7357

Need help please thanks

Answer:

x-intercept = 3 ; y-intercept = -5

Step-by-step explanation:

Lets rearrange the equation into the form y = mx + b:

5x - 3y = 15

-3y = 15 - 5x

Divide by -3:

y = 5x/3 - 5

Here we know that b (-5) is the y-intercept, and we can find the x-intercept by starting at the y-intercept and using the slope till we get the x-intercept. Or you can set y = 0 and solve for x, either way you get x-intercept = 3.
