Answer:
The equation that represents the line passing through the point (2, -4) with a slope of one half is

Step-by-step explanation:
The equation of a line can be described by a first order equation in the following format:

In which a is the slope of the line.
Solution:
The line slope is
, so
.
The equation of the line now is:

The problem states that the line passes through the point(2,-4). This means that when x = 2, f(x) = -4
So:




So, the equation that represents the line passing through the point (2, -4) with a slope of one half is

B. 7 because 24 + 24 = 48 meaning 6 cars have been washed within 48 mins. 1 car can be washed in 8 mins. 48 + 8 = 56
Answer: 750 miles
Step-by-step explanation:
The gas mileage is 75 miles per 1/2 gallon of gasoline.
First find how many miles it can go on 1 gallon of gasoline:
= 75 ÷ 1/2
= 150 miles
If the scooter can go 150 miles on 1 gallon, the number of miles it will go on 5 gallons is:
= 5 * 150
= 750 miles
Step-by-step explanation:
questions 8, obviously the mid part of the parabola is 3, that is the axis of symmetry.
question 9, only one solution because you only have one parabola.
