Answer:

y = -2/3 + 18

Step-by-step explanation:

2x + 3y = 18 ----- here is the equation...

-2x - 2x ----- bring the 2x to the other side

3y = -2x + 18 ----- now you have to divide everything by 3 to get y by itself

y = -2/3 + 18 ----- Done!

Answer:

y= -2/3x + 6

Step-by-step explanation:

Subtract 2 from both sides of the Equation:

3y=18-2x

Divide each term by 3 and simplify:

y= - 2x/3 +6

Rewrite into slop-Intercept form;

y=2/3x+6

What is the value of y if y = |– 5|?<br><br> explain how you would get the answer step by step

Andrews [41]

Answer:

y=5

Step-by-step explanation:

The answer is 5 because that sign around the -5 is the absolute value sign. What the absolute value sign does is it measures the distance from 0 the number is. Since the number -5 is 5 units away from the number 0, then y=5.

Solve for x: 4/x - x/8 = 0

Lostsunrise [7]

Answer:

$x = \sqrt{32}$

Step-by-step explanation:

$\frac{4}{x} - \frac{x}{8} = 0\\\\\frac{4}{x} = \frac{x}{8}\\\\x^2 = 32\\\\x = \sqrt{32}$

What is the GCF of -2xy and -9y

NNADVOKAT [17]

Answer:

$- y(2x + 9)$

Step-by-step explanation:

The GCF doesn't have to be a number. In this case, it is -y because both the -2xy and -9y share it. It's also easier when you take out a negative. Once you take the GCF out, your new expression should be:

$- y(2x + 9)$

If M is the midpoint of PQ and X is the midpoint of PM then PX = a PQ Which statement is True? a is equal to 1 a is equal to 1/2

garik1379 [7]

Answer:

D. a is equal to $\frac{1}{4}$

Step-by-step explanation:

Let us assume that segment PQ is 8 units, so that its midpoint M is at 4 units to both P and Q.

Given that X is the midpoint of PM, this implies that X is at 2 units to both P and M.

Then;

PX = aPQ

⇒ = a x 8

= 8a

Therefore, a must be equal to $\frac{1}{4}$ , so that;

PX = 8a

= 8 x $\frac{1}{4}$

= 2 units

Thus, a is equal to $\frac{1}{4}$ is the correct option.
