Answer:
He drove 63 miles in one day
Step-by-step explanation:
151.2/2.4=63
Option A is true because the sum of angles in a triangle is 180, so we can rule that one out immediately.
We can solve for x for the other 3 options by setting up this equation:
7x+2 + 4x+7 + 8x = 180 | Simplify
19x + 9 = 180 | Subtract 9
19x = 171 | Divide by 19
x=9
Now we can substitute x into all the values:
<J = 7x+2 = 65
<L = 4x+7 = 43
<K = 8x = 72
Looking at the options again, we can see that A, B, and D are true, leaving C to be false.
Answer:
slope is -3 and y intercept is 1
Step-by-step explanation:
The slope is the difference between two points on a graph. The y intersept is where the line touches the y axis. That majes the y intersept 1.
