Answer:
BC = 20
Step-by-step explanation:
AC = AB + BC
28 = x-10 + x+2
Combine like terms
28 = 2x -8
Add 8 to each side
28+8 = 2x-8+8
36 = 2x
Divide by 2
36/2 = 2x/2
18 =x
We want to find BC
BC = x+2
=18+2
=20
There are an infinite number of 3 number sets that will equal 9000, unless your looking for whole numbers.
If you want to find a set of whole numbers, first break 9000 into its factors:
5 * 5 * 5 * 3 * 3 * 2 * 2 * 2 = 9000
Now to find a set of 3 numbers, just combine some of the factors.
For example:
(5 * 5 * 5) * (3 * 3) * (2 * 2 * 2) = 9000
125 * 9 * 8 = 9000
Answer:
-3/2
Step-by-step explanation:
We can find the slope between two points using
m = (y2-y1)/(x2-x1)
= (-7 - -1)/(5 - 1)
(-7+1(/(5-1)
-6/4
-3/2
Answer:
y>0.5
Step-by-step explanation:
Rearrange the equation so "y" is on the left and everything else on the right.
Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>
Shade above the line for a "greater than" (y> or y≥)
or below the line for a "less than" (y< or y≤).
y+x>1
-y -y
x>1-y
2x+y<3
-y -y
2x<3-y
divide by 2
x<1.5-y/2
1.5-y/2>1-y
-1.5+y -1.5+y
<u>y>0.5</u>
