Actually in response to the other person’s answer, the answer would be a negative number since the slope is falling and not rising. 3 is right though so
-3
If you don’t understand rise over run, rise is vertical so going up or down and run is horizontal going left or right. Choose two random points that have both x and y as whole numbers. From the most left point going to the most right point, count the whole numbers in between to get to the right point.
Ex: (0,3) & (1,0). Vertically * going | , which is basically the y* 3 to 0 is subtracting 3 so -3 will be the numerator. Horizontally * going _ , which is the x) 0 going to 1 is adding 1 so 1 will be the denominator. -3/1 is -3
Another way to find slope is take two points and do y2-y1/x2-x1 Where you plug in the (x,y)
Ex: (0,3) & (1,0) 0-3/1-0 = -3/1 = -3

We need I = prt, where p = principle, I = interest, r = interest rate and t = time (in years).
I = prt
14 = 100r(1)
We now solve for r.
14 = 100r
Divide both sides by 100 to isolate r.
14/100 = 100r/100
0.14 = r
Now change 0.14 to a percent multiplying by 100.
100(0.14) = r
14 = r
The interest rate is 14%.
3/4 = .75 so you have to find 75 % of 3/9
100% = 3/9
1% = (3/9)/100
75% = (3/9)/100 * 75 =.25
10 square units.
The quadrilateral is 2 x 2 = 4
Triangle a 2 x 2 = 4; divided by 2 = 2
Triangle b 4 x 2 = 8; divided by 2 4
4 + 2 + 4 = 10 units squared
Answer:
-8n + 9
Step-by-step explanation:
Given that,
A = -3n + 2
B = 5n - 7
Before solving you have to know that,
( + ) × ( + ) = ( + )
( - ) × ( - ) = ( + )
( + ) × ( - ) = ( - )
Let us solve now.
A - B
-3n + 2 -(5n - 7)
-3n + 2 - 5n + 7
Combine like terms
-3n - 5n + 2 + 7
-8n + 9
Hope this helps you.
