One crew is doing 1.3 miles daily, the other is doing 1.4 miles daily, so both together are doing 1.3 + 1.4 miles daily, namely 2.7 miles.
now, they are 6.75 miles apart, how many days will it be at a rate of 2.7 miles per day, that 6.75 miles will be done?

days
Answer:
rewrite it to y=2x+3 and graph?
Step-by-step explanation:
<u>☁️</u><u>My Answer☁️:</u>
y = 90°
<u>✧My Step-by-step explanation✧:</u>
The angle x forms a straight line with the both the 50° angle and the 40° angle:
x + 50° + 40° = 180°
x = 90°
Which means…
y = x = 90°
Answer:

Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point (8,1) and a slope from the equation. We will chose point-slope since we have a point and slope.
Point slope:
in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is
.
We will substitute
and
.


This is the equation of the line perpendicular to the equation given that crosses through (-2,3).
