Answer:
y=7 so all of the y's are 7 but the last one is 4
The slope of the linear function is negative. Then the correct option is B.
<h3>What is the slope?</h3>
The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
The graph of a linear function is shown.
From the graph, as the value of x is increasing then the value of y is decreasing. Then the slope is negative.
Then the correct option is B.

Answer:
Step-by-step explanation:
Let
C(t) ---->the total cost of the electrician's services in dollars
t ---> the number of hours
we know that
The linear function in slope intercept form is equal to
where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
the y-intercept is equal to
----> set fee
we have the ordered pair (2,250)
substitute the given values
Solve for m
The linear function is equal to
Answer:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
a-(9*x^2-6*x+1)=0
STEP
1
:
Equation at the end of step 1
a - ((32x2 - 6x) + 1) = 0
STEP
2
:
Equation at the end of step 2
a - 9x2 + 6x - 1 = 0
STEP
3
:
Solving a Single Variable Equation:
3.1 Solve a-9x2+6x-1 = 0
