Answer:
Dude the answer is 8!
Step-by-step explanation:
You literally multiply the two together. Come on man...
All you need to do is divide -1/2 onto the other side.
-1/2x<-12
-12/ (-1/2)= 6 (a negative and a negative equals a positive)
Also, since you are dividing a negative, you flip the sign.
x>6
I hope this helps!

Answer:
Step-by-step explanation:
Formula for calculating the surface area of the box S = 2(LW+LH+WH) where
L is the length of the box
W is the width of the box
H is the height of the box
If the box is square based with dimension 4 * 4in, then L = W = 4in. substituting this values given into the formula we will have;
S = 2(4(4)+4H + 4H)
S = 2(16+8H)
S = 32+16H
<em>Hence, The function that represents the surface area of this box as a
</em>
<em>function of its height is S = 32+16H where H is the height of the box</em>
<em></em>
Given H = 6.5in, to evaluate the function, we will substitute h = 6.5in into the modeled equation;
S = 32+16H
S = 32+16(6.5)
S = 32+106
<em>S = 138in²</em>
<em>Hence the total surface area of the box is 138in²</em>
Answer:
<h2>width = 6 feet</h2>
Step-by-step explanation:
let l be the length of the rectangle
let w be the width of the rectangle
The statement
The length of a rectangle is 6 feet more than three times the width of the
rectangle is written as
l = 6 + 3w
From the question
l = 24 feet
Substitute the value into the above formula and solve for the width
That's
24 = 6 + 3w
3w = 24 - 6
3w = 18
Divide both sides by 3
w = 6
Therefore
<h3>width = 6 feet</h3>

Answer:
B. y=7x+3
Step-by-step explanation:
You find the changes of y over the changes of x. y sub 2 - y sub 1 divided by x sub 2 over x sub 1. So, 17 - 10 over 2 - 1 = 7. 3 is the y-intercept. y=7x+3
