Answer:
1. y=5/2x+4
2. y=-7x-3
Y=mx+b is slope intercept form
Step-by-step explanation:
You have to add it in the slope intercept formula
2. M=-7 and B=-3
so y=-7x-3
M = 5/2 B = 4
So y = 5/2x+4
Answer:
9
Step-by-step explanation:
Calculate the absolute difference of the 2 points, that is
| - 7 - 2 | = | - 9 | = 9 , or
| 2 - (- 7) | = | 2 + 7 | = | 9 | = 9
Answer:
.0087
Step-by-step explanation:
8.7 x 10^-3
10^-3 means move the decimal to the left 3 places. The negative means left, positive would mean right. We add 0 to make enough places to move it to the left 3
008.7
Move it 3 places left
.0087
This is in standard form
Answer:
Step 2
18 over 8 to a decimal is 2.25
Step-by-step explanation:
Step 1, 20, subtract 16 labeled as
Step 2, 40 labeled as
Step 3, subtract 40, and 0 labeled as Step 4.
Divisor = 8
Divided = 18
Quotient = 2.25
2.25
8 √18
- 16
2 0
- 16
4 0
- 40
0
The first error is at step 2
18 over 8 to a decimal is 2.25
