Solve: |4x + 5| + 8 >(or equal to)45

1 answer:

8 0

This is pretty simple once you get used to this

First set it equal to the original and the negative one
(>_) is the bigger and equal to part

4x+5>_45 or 4x+5>_-45

Then solve for x for both

4x>_40. 4x>_-50
X>_10 X>_-25/2

Answer:

y = 3x+9

Step-by-step explanation:

We can use the slope intercept form

y = mx+b

where m is the slope and b is the y intercept

y = 3x +b

Substitute the point into the equation

6 = 3(-1) +b

6 = -3+b

Add 3 to each side

6+3 = -3+3+b

9 = b

y = 3x+9

Answer:

p = 3

Step-by-step explanation:

27p + 6.25 = 87.25

- 6.25 -6.25 = 27p + 0 = 81 = 27p = 81

81/27 = 3

p = 3

Micah was asked to add the following expressions: 3x2−x−9x2+3x+2+−2x2+2x+5x2+3x+2 First, he combined like terms in the numerator

shtirl [24]

Micah was asked to add the following expressions:

$\frac{3x^2-x-9}{x^2+3x+2} + \frac{-2x^2+2x+5}{x^2+3x+2}$

First, he combined like terms in the numerator and kept the common denominator

First step is correct. He added the like terms in the numerator, because the denominators are same.

$3x^2 -x -9 -2x^2+2x+5becomes x^2 +x -4$

So he got , $\frac{x^2+x-4}{x^2+3x+2}$

In the next step, he cannot cancel out x^2 from the top and bottom . Because x-4 and 3x+2 are added with x^2

If we have x^2 is multiplied with other terms at the top and bottom , then we can cancel out x^2.

So Micah added the expression incorrectly. Final answer is not correct.
