Answer:
false
Step-by-step explanation:
you only need to reverse the sign when you are dividing by a negative number
The river will not reach a level of 7 ft. after 5 hours.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the height of the water level after x hours.
Since the river is 1 ft below its average water level and begins to rise by a constant rate of 1.5 ft per hour. Hence:
b = -1, m = 1.5. The equation becomes:
y = 1.5x - 1
To reach a level of 7 ft. That is y = 7:
7 = 1.5x - 1
1.5x = 8
x = 5.3 hours
The river will not reach a level of 7 ft. after 5 hours.

Hello there!
To start off this problem, let's replace f(x) with x in the equation. This gives us the following.

Subtract 3/4*x from both sides.



Now, multiply both sides by 4 to eliminate the fraction on the left side.

Your answer is B. Hope this helps! :)
