<u><em>Answer:</em></u>
The slope of the line is 77
<u><em>Explanation:</em></u>
We know the speed is constant and that the mile-marker location over time can be represented by a line. This means that the equation is linear.
<u>The slope can, therefore, be calculated as follows:</u>

where (x₁ , y₁) and (x₂ , y₂) are two points on the line
We are given that the two points (1, 123) and (3, 277) are two points in the line
<u>Substitute with them in the above equation to get the slope as follows:</u>

Hope this helps :)
I believe the answer is 1. One is the only number that can go into both 8 and 9.
Answer:
x = -3
y = 7
Step-by-step explanation:
y = -2x + 1
7 = -2x + 1
<u>-1 -1 </u>
6 = -2x
divide by -2
x = -3
Y=kx
k=constant of variation
given
k=12
y=36
36=12*x
divide both sides by 12
3=x
x=3
Answer:
Step-by-step explanation:
<u>Use cosine:</u>
- cos = adjacent / hypotenuse
- cos ∠L = KL/JL
- cos 21° = 4/x
- x = 4 / cos 21°
- x = 4.3 (rounded)
