The answer is .75=a
2a+3=4a+5
-2a -2a
3 = 4a+5
-5 -5
3 = 4a
3/4 4/4
.75 = a
Yes. Speed is distance over time. Since Rachel rode 18.2 miles in 1.4 hours, her speed was 13miles/hour.

Step-by-step explanation:
<u>Given points:</u>
<u>Let's calculate it's equation:</u>
- y = mx +b
- m = (4 + 11)/(6 +3) = 15/9 = 5/3
- y = 5/3x + b
- -11 = 5/3*(-3) + b ⇒ b = -11 + 5 = -6
- y = 5/3x - 6
<u>The given line:</u>
Compared, the lines have different slope (5/3 vs 32) but same y- intercept (-6), so both pass through the point of (0, -6). y= 32x - 6 has greater rate of change.

Step-by-step explanation:
Given that:
Credit card balance = $34
Amount of sandwich purchased = $40
The cost of sandwich purchased us added to the Initial credit card balance as the balance in a credit card is amount owed.

Hence; new card balance :
(Intial card balance + cost of sandwich)
$34 + $40 = $74
