Joy recently hired a mechanic to do some necessary work. On the final bill, Joy was charged a total of $991. The amount listed for parts was $475 and the rest of the bill was for labor. If the hourly rate for labor was $43, how many hours of labor was needed to complete the job?
(A) First write an equation you can use to answer this question. Use x as your variable. The equation is ___________
(B) Solve your equation in part (A) to find the number of labor hours needed to do the job. Answer: The number of labor hours was _____________
Answer:
12 hoursStep-by-step explanation:
Given:
The total amount = $991Cost of parts = $475Hourly labor rate = $43Number of hours = x(A)
The equation:
y = 43x + 475(B)
Solve for x:
43x + 475 = 99143x = 991 - 47543x = 516x = 516/43x = 12someone help me if you can :)

A Child’s Growth and Prosperity
When a new baby enters this world, pediatricians will monitor the baby’s growth in many areas. Weight, head circumference, length, and body mass index are just a few of the measurements collected as newborns progress through childhood. Parents of newborns are not only concerned with their child’s measurements, but they typically consider their child’s medical and financial needs, too.
As you complete the task, keep these questions in mind: How can you use linear functions to describe and analyze measurements associated with babies’ growth? How can you use functions to calculate college savings and to determine how much medicine to administer?

Answer:
a) 0.75 inch/month
b) y-20 = 0.75(x-4)
c) 17 inches
d) 44
a) 0.8 inch/month
b) yes
c) y = 0.8x + 18.8
d) 18.8 inches
Step-by-step explanation:
a) (21.5-20)/(6-4) = 1.5/2
= 0.75 inch/month
If this is correct, 2 months after the 6th month (month 8), it should be
21.5 + 2(0.75) = 23
Which it is
b) y-y1 = m(x-x1)
Where y is the length, x is the months, m is the slope and (x1,y1) is a known point
At x = 4, y = 20
y-20 = 0.75(x-4)
Or
y = 0.75x + c
20 = 0.75(4) + c
c = 20 - 3 = 17
y = 0.75x + 17
c) at birth, 4 months before month 4
So, 20 - 0.75(4) = 17
Which is also the y-intercept
d) y = 0.75(36) + 17
y = 27 + 4 = 44 inches
Generally, at the age of 3 years (36 month) the length is between 35 and 40 inches
a) slope = (30-22)/(14-4)
= 0.8 inch/month
b) 0.8 > 0.75, so yes
c) When x = 4, y = 22
y-22 = 0.8(x - 4)
y - 22 = 0.8x - 3.2
y = 0.8x + 18.8
y-intercept is 18.8
d) at birth, x = 0.
Length was 18.8 inches

Age of President G.H.W. Bush is 37.
What is Unitary Method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Age of President Bush = 54,
So, Age of President Clinton
=(54/2) + 14
=27+14
=41
Now, Age of President G.H.W. Bush
=46/2+14
=23+14
=37
Hence, the age of President G.H.W. Bush is 37.

What is the Co ordinates to fill in the grid in the top left?
Answer:
a ) x = - 3, y = 5
x = 0, y = 2
x = 5, y = - 3
b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.
Step-by-step explanation:
y = 2 - x
When x = - 3,
y = 2 - x
= 2 - ( - 3 )
= 2 + 5
y = 7
When x = 0,
y = 2 - x
= 2 - 0
y = 2
When x = 5,
y = 2 - x
= 2 - 5
y = - 3
b ) you should draw the line by marking the coordinates in the graph, then draw a straight line passing through all those three points.

15 tan^3x=5tanx,(0,2pi)
Answer:
steps below
Step-by-step explanation:
15 tan³x=5tanx .... (0,2π)
5tanx(3tan²x - 1) = 0
tanx = 0 x = π (0° is excluded)
or 3tan²x - 1 = 0
(√3 tanx + 1) (√3 tanx - 1) = 0
tanx = 1 /√3 x = π/6 (30°) or x = 5π/6 (150°)
tanx = - 1 /√3 x = 7π/6 (210°) or x = 11π/6 (330°)

Finally, suppose you decide not to finance (get a loan for) the car and to
wait two years to save up money in addition to the $4,000 you already
have saved for the car.
How much money would you have to save each month in order to
purchase this car without any financing (loan) at the end of two years?
Round your answer to the nearest cent.
Supposing a cost of $30,000, and using proportions, it is found that you would have to save $1,083.30 each month.
--------------------------
We suppose a cost of $30,000.You already have $4,000 saved.30 - 4 = 26, thus, you would need to save $26,000 in 2 years = 24 months.How much per month?We can solve it using proportions, by the following rule of three:
1 month - $x
24 months - $26,000
Applying cross multiplication:
[tex]24x = 26000[/tex]
[tex]x = \frac{26000}{24}[/tex]
[tex]x = 1083.3[/tex]
You would have to save $1,083.30 each month.

Two trains leave the same city at a right angle to each other and continue in straight lines. Train B travels 5 mph faster than train A. After two hours, they are 50 miles apart. Determine the speed of each
train.
