9 divided by 3 = 3
12 divided bye 3 = 4
Answer:
x = 3
Step-by-step explanation:
Since the two legs of the outer triangle equal the same (12), it is safe to assume the two legs of the inner triangle will equal the same. Therefore, x is equal to 3.

Slope = 2
Y intercept = -3
====================================================
Explanation:
We'll use the template y = mx+b
m = slope
b = y intercept
The y intercept always occurs when x = 0. In this case, b = -3 due to the first row of the table.
The slope is m = 2 because each time we increase x by 1, the y value goes up by 2.
So we can say
m = slope = (rise)/(run) = (change in y)/(change in x) = (2)/(1) = 2
Or we can apply the slope formula
m = (y2-y1)/(x2-x1)
using any two points of the table.
--------------------
Since we know m = 2 and b = -3, this means we get
y = mx+b
y = 2x+(-3)
y = 2x-3

Can someone PLEASE solve this quadratic equation by factoring with the steps? :(
y= x squared +2x - 2
Answer:
There are no simple factors to this expression. You can however solve for x, giving you:
x = -1 ± √(y + 3)
Step-by-step explanation:
There is no simple pair of factors to this equation, so we'll have to go through the full process. You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2. We can however solve for x:
[tex]y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}[/tex]
solve for x
925 + x = 652
Answer:
x=-273
Step-by-step explanation:

7.) (0, 2)
Slope of (0, 2) and (-10, -16) = 2 - (-16) ÷ 0 (-10) = 18/10 = 9/5
8.) a. Slope of (17, -12) and (17, 8)
8 - (-12) ÷ 17 - 17 = 20 ÷ 0 = undefined
b. Slope of (6, -2) and (-3, 1)
1 - (-2) ÷ -3 - 6 = 3/-9 = -1/3
9.) (-3, 33) and (4, -9)
-9 - 33 ÷ 4 - (-3) = -42/ 7 = -6
10.) Hourly: c = 75h + 15
c - charge
h - hours
1 hour
c = 75 (1) + 15
c = 75 + 15 = 90
The hourly charge for services is $90.
11.) C. A newborn weighs 8 pounds and gains 1.5 pounds each month for the next 3 months.
A rectangle has a height of 4x and a width of 3x + 1.
Answer:
area of rectangle= length x width
height 4x and width = 3x+1
area of recatangle=4x(3x+1)
=12x^2+4x
perimeter of recatangle=4x+3x+1+4x+3x+1=14x+1

Answer:
12.4949707813 MPH ( it might want you to round, which then of course would be 12.5 MPH.
Step-by-step explanation:
You need to take the number 20 (the diameter) and multiply it by pi. You then get 62.8318530718. You need to multiply that by 3.5, which then gets 219.911485751.

A car rental agency charges 150 per week +0.45 per mile to rent car express the weekly cost to rent a car if as a function of the number of miles driven during week X
Answer:
The required function is:
[tex]C(x) = 150+0.45x[/tex]
Step-by-step explanation:
We have to represent the given scenario as an equation or function
Let x be the number of miles driven in a week
Let C(x) be the function of the number of miles driven
As it is given that charges are 150 per week, these charges are constant so they will be used as it is.
It is also given that the cost of car is 0.45 per mile so for x miles the cost will be:
0.45x
Combining both terms, we get
[tex]C(x) = 150+0.45x[/tex]
Hence,
The required function is:
[tex]C(x) = 150+0.45x[/tex]
