How do I show work for -2x-7=3(4x+7)

Mathematics

Alona [7]3 years ago

Answer:

x=-2

Step-by-step explanation:

-2x-7=3(4x+7)

distribute

-2x-7 = 3*4x +3*7

-2x-7 = 12x+21

add 2x to each side

-2x-7+2x = 12x+2x+21

-7 = 14x+21

subtract 21 from each side

-7-21 = 14x+21-21

-28 = 14x

divide by 14

-28/14 = 14x/14

-2 =x

-2x - 7 = 3(4x + 7)      Distribute/multiply 3 into (4x + 7)

-2x - 7 = 12x + 21       Add 2x on both sides

-2x + 2x - 7 = 12x + 2x + 21

-7 = 14x + 21      Subtract 21 on both sides

-7 - 21 = 14x + 21 - 21

-28 = 14x     Divide 14 on both sides

-2 = x

Maureen bought a coat. She was excited because it was on sale, so she paid $15.25 less than the original price. She paid $48.75
irga5000 [103]

Answer:

$33.50 for coat, 5.5 hours

Step-by-step explanation:

For the coat, since it was on sale, then it would be $48.75-$15.25=p=$33.50.

If the temperature drops 4 degrees every hour, if t dropped 22 degrees, then you would do 22 divided by 4, to find out how many hours it had dropped for. 22 divided by 4=h=5.5 or 5 1/2.

Consider the function represented by 9x + 3y = 12 with x as the independent variable. How can this function be written using
MArishka [77]

Answer:

f(x) = -3x + 4

Step-by-step explanation:

Step 1: Write it in slope-intercept form

9x + 3y = 12

3y = -9x + 12

y = -3x + 4

Step 2: Replace <em>y</em> with f(x)

f(x) = -3x + 4

In math, function f(x) is equal to the variable <em>y</em>.
