Answer:

x > -7

Step-by-step explanation:

Isolate the variable, x. Treat the < sign like an equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& roots)

Multiplication

Division

Addition

Subtraction

First, subtract 15 from both sides:

-8x + 15 (-15) < 71 (-15)

-8x < 71 - 15

-8x < 56

Next, divide -8 from both sides of the equation. Note that when you divide by a negative number, you must flip the sign:

(-8x)/-8 < (56)/-8

x < (56)/-8

x > -7

x > -7 is your answer.

Answer:

Any number greater than but excluding -7.

Step-by-step explanation:

-8x + 15 < 71

-8x < 71 - 15

-8x < 56

56 divided by -8 = -7

So, that means anything greater than -7 would result in a lower number than 71.

Need some help with this question
Elza [17]

Answer:

5 units down.

Step-by-step explanation:

D' is the translated image. If D' is at (7,1) and the original point, D, is at (7,6), we can see a change of -5 in the y coordinate. This means that there was a translation of 5 units down.

Find the slope of the line passing through the pair of points:<br> (-6,-1), (-6,4)
Dima020 [189]

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (-6, -1) and (-6, 4).

Substitute:

m=\dfrac{4-(-1)}{-6-(-6)}=\dfrac{4+1}{-6+6}=\dfrac{5}{6}\ !!!

Dividing by 0 is not possible, therefore the slope is undefined.

<em>It's a vertical line x = -6</em>.
