Answer:
You should graph the lines (0, 0) to (2, 120), (2, 120) to (2.5, 120), and (2.5, 120) to (3.5, 150).
Step-by-step explanation:
If we see, for the first part, she drive 60 miles an hour and drives for 2 hours. This means that after 2 hours, she has driven 60 * 2 = 120 miles in 2 hours. Then she spends 30 minutes, or half an hour, no moving forward as she changes the tire. Finally, she drives at 30 miles an hour for an hour. This means she has driven 120 + 30 = 150 miles in total after 3 and a half hours.
Our first line goes from (0, 0) to (2, 120), as thats how far we drove in 2 hours. The next line goes from (2, 120) to (2.5, 120), as she was changing a tire and made no progress. Finally, the last line goes from (2.5, 120) to (3.5, 150), as she drives for another hour at 30 miles an hour.
My other answer got deleted.. I did answer your question, but whatever.
You are correct, the answer is D. a reflection across y = x then a positive rotation of 270 degrees about the origin.
Answer:
5
Step-by-step explanation:
● 2(5v+3) - 4(7v+1) = -88
● 10v + 6 - 28v - 4 = -88
● (6-4) + (10v-28v) = -88
● 2 + -18 v = -88
● -18v = -90
● v = 90/18
● v = 5
Answer:
• x = 0
• x = b/a
Step-by-step explanation:
Subtract the term on the right and factor:
ax^2 -bx = 0
x(ax -b) = 0
The zero product rule lets you write this as two equations:
x = 0
ax -b = 0
The latter can be rearranged to ...
ax = b
x = b/a
Of the choices shown, the equations for x are ...
x = 0
x = b/a
Answer:
a
