Answer:
y=3/2(x)+4
Step-by-step explanation:
Because line AB is perpendicular to line BC, the slope of AB is equal to 3/2. Substituting (-2,1) into the new equation gives us "1=3/2(-2)+b" which simplifies to 1=-3+b. This means that b=4.
The number of miles for which the car has been driven if one paid $122.50 as in the task content is; 2.5 miles.
<h3>For how many miles was the car driven?</h3>
It follows from the task content that the total amount paid was; $122.50.
Hence, after subtraction the constant charges, for the day and for gas, the remainder is;
$122.50 - $50 - $35
= $37.50.
Ultimately, if the charge per mile is $15, then the number of miles driven is; $37.50/$15
= 2.5 miles.

Answer:
10
Step-by-step explanation:
The formula is
the square root of y1-y2 +x1-x2 (square root of everithing)
(-11)-(-1) + 0-0
(-11) - (-1) = -11 +1 = -10 0-0 = 0
The quare root of 10 squared is 10
You plug -3 into -2x-7 and you get B -1.
