Answer:
<h2>y=7x+10</h2>
Step-by-step explanation:
Step one:
Base fee Charge= $10
Charges per hour= $7
Let the number of hours be x
and let the total charges be y
Step two:
the linear function for the total charges can be represented using the equation of a straight line, which is
y=mx+c
where y= tota charges
m= the charges per hour
x= is the number of hours worked
c= the base fee
Step three:
the equation is
y=7x+10

Here is my anser:
We need to find the slope of the of and from the graph, we see that if x increases from 2 to 4, y decreases from 4 to -2. Thus, the slope of the blue line is :
= -3
But the slope of the perpend. bisector of the blue line is the negative reciprocal of -3, or m= 1/3.
Let's find the slope-intercept form of this bisector. We need to determine b in y=mx+b. Referring to the midpoint of the blue line, x= 3; y= 1; and m=1/3. Then
y=mx+b becomes 1=(1/3)(3) + b. Solving for b: 1=1+b. Then b=0.
Thus, the equation of the perpendicular bisector of the blue line through (3,1) is y=mx + b, or y=(1/3)x + 0, or y=x/3.
Answer:
Step-by-step explanation:
y = -8x - 49
y = -x
- -8x - 49 = -x
- -8x + x = 49
- -7x = 49
- x = -7
- y = - (-7) = 7
