-(2x + y) + 3(x-4y)
-(2x + y) + 3x - 12y
-2x + 3x - y - 12y
x - 13y
So therefor the answer is x - 13y

Which explanation correctly tells whether these ratios are equivalent and why?

Reptile [31]

<h3><u>Answer:</u></h3>

<u>Option A (Yes because 3 x 2 = 6 and 14 x 2 = 28.) is correct.</u>

<h3><u>Step-by-step explanation:</u></h3>

<u>This is because if we simplify 3/6 and 14/28, both of them will get 1/2. This means that only A and C are possible.</u>

=> Option A is correct because 3 x 2 does equal 6 and 14 x 2 does equal 28.
=> Option C is incorrect because 3 x 5 does not equal 14 and 6 x 5 does not equal 28.

What is the solution to the inequality below x2>25

4vir4ik [10]

Answer:

Ans: (-5, 5)

-5 < x < 5

Step-by-step explanation:

Standard form: f(x) = x^2 - 25 < 0.

First solve x^2 - 25 = 0 --> x = +- 5

Use the algebraic method to solve f(x) < 0. Between the 2 real roots (-5) and (5), f(x) < 0, as opposite in sign to a = 1.

Answer by open interval: (-5, 5)

Put the following equation of a line into slope-intercept form, simplifying all fractions. 3x-5y= -30

anastassius [24]

Slope intercept form is y=mx+b. So let's use the given equation and turn it into this form.

$3x-5y=-30$

Move the -3x to the right side

$-5y=-3x-30$

Divide both sides by -5

$y=\dfrac{3}{5}x+6$

This should be your answer, let me know if you need any clarifications, thanks!
