Answer:
Slope intercept form:
<em>y = mx + b</em>
What we are given:
49x - 21y = -1,470
we need to keep y on the left side so we subtract 49x from both sides;
-49x -49x
-21y = -49x - 1,470
we need to make y one so we divide by -21 from both sides;
÷-21 ÷-21
y = -49x/-21 - 70
which simplifies to
y = 7x/3 - 70
The answer is "Design B bulbs will likely last longer than design A bulbs."
The box in a box plot represents the middle 50% of the data. The box for the design B bulbs is farther out than the box for the design A bulbs. Therefore, design B bulbs last longer on average than design A bulbs.

Answer:
Charmaine earns $60.90 for 6h for mowing and 1h for babysitting.
Step-by-step explanation:
We must write the data problems.
Charmaine = $8.80/h mowing
Charmaine = $8.10/h babysitting
How much will Charmaine earn for 6 h mowing and 1 h babysitting?
1 h mowing ....................... $8.80
6 h mowing ....................... $x
x = 6 h mowing * $8.80
x = $52,8
To find the total earn of Charmaine, we have to gather the earns from mowing and babysitting.
$52,8 (from mowing) + $8.10 (from babysitting) = $60.90
