Answer:
he spent $0.15 on each pencil
Step-by-step explanation:
12x4= 48, which is the exact amount of pencils he bought, and then divide them by the price
7.20 divided by 48 is 0.15.
Therefore, each pencil is 0.15 cents a piece

Answer: x = -8</h3>
Explanation:
Both points have the same identical x coordinate, so this line is completely vertical. Vertical lines are always of the form x = k, where k is some constant.
The equation must be x = -8 since we want both x coordinates to be -8.
Side note: The slope of this line is undefined, which applies to any vertical line.
Answer:
Step-by-step explanation:
if C is the right angle,
AB is the hypotenuse
AB^2=AC^2+BC^2
AC^2=13^2-5^2
AC^2=169-25=144
AC=
=12
AC=12
How does this have anything to do with factoring?
Perimeter of the rectangle would just be 2(3t-2)+2(5t+7)
Simplify that to get 6t-4+10t+14, then 16t+10
To find slope subtract the two points in the coordinate (y). We have 8 and 4 so subtract those two. You get 8-4=4. Now start from the same coordinate expect this time subtract (x). Which is 9-3=6. You have 4/6 simplify and you get 2/3. Your slope is 2/3. Hope this helps
