-6, because 8x+48=0, then 8x=-48, so x=-6

Answer:-6

Step-by-step explanation:

4(2x+12)=0

Open brackets

8x+48=0

Subtract 48 from both sides

8x+48-48=0-48

8x=-48

Divide both sides by 8

8x/8=-48/8

X=-6

Answer:

x>-\frac{11}{7}

Step-by-step explanation:

<u>Step 1:  Distribute</u>

<u />-\frac{5}{4} (8x+4)

(-\frac{5}{4} *8x)+(-\frac{5}{4} *4)

-\frac{40x}{4}-\frac{20}{4}

-10x-5

<u>Step 2:  Add 10x to both sides</u>

<u />-10x-5\mathbf{+10x}

-5

<u>Step 3:  Subtract 6 from both sides</u>

<u />-5\mathbf{-6}

-11

<u>Step 4:  Divide both sides by 7</u>

<u />-11\mathbf{/7}

x>-\frac{11}{7}

Answer:  x>-\frac{11}{7}

Photo above need help
Ira Lisetskai [31]

Answer:

m = 0

Step-by-step explanation:

<u>If two lines are parallel, their slopes are equal. </u>

The slope of x - axis is 0

(why?)

because, slope of a line is given by

\boxed{\mathsf{slope\:of\:a\:line=tan \theta}}

Θ is the angle made by the line with the x- axis.

Here, the line in question is the x- axis itself, and every line makes an angle of 0° with itself.

=> Θ = 0

=> tan Θ = 0

=> slope = 0

and the line in blue is parallel to the X- axis, therefore, it's slope is also 0

(also, a line makes an angle of 0° with the line it's parallel to)

Please someone help me and explain this question to me (the last question starting with a straw)
Anastasy [175]

Each straw is  4-1/8 inches long.
You have one gigantic piece of straw material, 123-3/4 inches long.
How many straws can you cut it up to make ?

 ===>                    (123-3/4)  divided by  (4-1/8)            straws.

Each one costs  $0.015  to make.
So, once you find the number of short straws you have,
multiply

===>                 (the number of short straws) x ($0.015) .

That'll tell you how much it costs to make all of them. 


Now you know how to do it on your own.
If you don't get  30 straws  and  $0.45 , please try again.
