Step-by-step explanation:
Answer:
First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).
Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).
Answer:
17 degrees is your answer.
Step-by-step explanation:
A triangle is 180 degrees.
<em>140 + 23 = 163</em>
You take 163 and subtract it from 180
<em>180 - 163 = 17</em>
17 degrees is your answer.
