1)B 5.007x10 -3
2)B 103,150
Mean is just another word for average. To find the average of something you must add up all values and divide by the number of values in the set.
<em>A(a) = 24 cm²</em>
<em>A(b) = 40.04 cm² ≈ 40 cm²</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>area formula (rectangle)</em>
<em>A = l × w</em>
<em>A(a) = 8cm × 3cm = 24 cm</em>
<em>A(b) = 5.2cm × 7.7cm = 40.04 cm² ≈ 40 cm²</em>
<em>Good luck !</em>
Answer:
A) y=1/3x+5
B) y=-2x+9
C) y=-3
D) y=2x+9
E) y=-10x+80
F) y=x-2
Explanation:
Use y=mx+b
m=slope
b=starting point (or where it crosses the y-axis
For slope, use rise over run.
To determine negative slope, read from left to right and see if it’s going up or down. If down it’s negative, if up then positive.
Also BE CAREFUL, on D, the y-axis is labeled differently. Take an extra look at it.
