Answer:
the unit rate is 80 miles per hour
Step-by-step explanation:
Just divide the total amount of miles by the number of hours it took to get there.
8000km per hour.
96,000/12=8000
In 4 hours, she read 3 chapters.
In 1 hour, she reads 3/4 chapters.
In 10 hours, she reads 3/4 x 10= 3/2 x 5 = 15/2 = 7 and a half chapters.
This is true. It would only be incorrect if dilations were there, because dilations don’t keep the shapes congruent.
ANSWER
|PQ|=10
EXPLANATION
The first line is
y=2x+8
We put y=0 to find the x-intercept.
0=2x+8
-2x=8
x=-4
(-4,0) are the coordinates of P.
The second equation is
y=2x-12
To find the x-intercept, we put x=0 into the formula:
0=2x-12
-2x=-12
x=6
The coordinates of Q are (0,6).
The distance between these two points.
|PQ|=|6--4|=10
