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 = 12Need helppppppppppppppppppppppppppppppppp

18. You have no more than $60 to spend. You want a drink that costs $1.50 including tax, and you want to buy a
pair of pants, which will have 4% sales tax.
a.) What is the inequality that represents the amount of money you have to spend?
b.) Given that you can spend no more than $60, what is the most a pair of pants could cost?
Answer:
a. pants + tax + drink ≤ 60 b. $56.16
Step-by-step explanation:
60-1.5 = 58.5 = money left for pants+tax
58.5/100 = 0.585 = 1%
0.585x 4= $2.34 = highest possible tax
58.5 - 2.34 = $56.16 most
pants + tax + drink ≤ 60

9514 1404 393
Answer:
y = 2·2^x
Step-by-step explanation:
When the exponential function is of the form ...
y = a(b^x)
The value of 'a' is the value of y when x=0. The table tells us a = 2.
The value of 'b' is the ratio between values of y when their corresponding x-values differ by 1. The table tells us b = (4/2) = 2.
Then the exponential function describing the table is ...
y = 2(2^x)

how do i calculate slope?
Answer:
In order to calculate the slope, you'll need 2 ordered pairs (x, y).
The formula for calculating the slope is:
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
where m = slope
(x1, y1) = first ordered pair
(x2, y2) = second ordered pair
Regardless of which values for the (x1, y1) and (x2, y2) you choose, you would still end up with the same slope (as long as it's done correctly).
As an example, let's say you have the following set of points:
(2, 4) (8, 1)
Let (x1, y1) = (2, 4)
(x2, y2) = (8, 1)
Plug these values into the slope formula:
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
[tex]m = \frac{1 - 4}{8 - 2} = \frac{-3}{6} = -\frac{1}{2}[/tex]
Therefore, the slope of the line is - 1/2.
To prove that you'll end up with the same value for the slope:
This time, let (x1, y1) = (8, 1)
(x2, y2) = (2, 4)
[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]
[tex]m = \frac{4 - 1}{2 - 8} = \frac{3}{-6} = - \frac{1}{2}[/tex]
Therefore, the value of the slope is still -1/2.

Step-by-step explanation:
A line passes through (-2,4), (-4, 8), and (n, -4). Find the value of n.
Answer: n = 2 ....... (2, -4)
Step-by-step explanation:
To find n, one must write the equation for the points given, which are (-2, 4) and (-4, 8). Remember, the standard linear equation is y = mx + b, where m is the slope of the line.
To find the slope, refer back to (y2-y1)/(x2-x1), or in this case, (8-4)/(-4+2), which gives us -2
With our slope of -2, we can write the equation as y = -2x+b. Now, we need to find b (the y-intercept) by plugging in a point as (x,y)
Let's use (-4,8) point and plug it into our linear equation: y = -2x+b
to get 8=(-2)(-4) +b
8=8+b
0=b (which means our y-intercept is 0)
Now, our official linear equation is y=-2x
The problem gives us (n, -4) where -4 y, so we plug in -4 as y in the equation to get:
-4=-2x
-4/-2=x
2 = x
And there we go :) I hope this helps!
Answer:
The value of n = 2.
Step-by-step explanation:
Given the following points passing through a line, (-2, 4), (-4, 8), and (n , -4) wherein we must find the value of n:
It helps to determine the equation of the line, using the slope-intercept form: y = mx + b, where:
m = slope (rate of change), which measures the steepness of the line.b = y-coordinate of the y-intercept; it is the point on the graph where it crosses the y-axis. Slope:In order to solve for the slope of the line, use the following slope formula:
[tex]\displaystyle\mathsf{m =\:\frac{y_2 - y_1}{x_2 - x_1}}[/tex]
Let (x₁, y₁) = (-2, 4)
(x₂, y₂) = (-4, 8)
Substitute these values into the slope formula.
[tex]\displaystyle\mathsf{m =\:\frac{y_2 - y_1}{x_2 - x_1}}[/tex]
[tex]\displaystyle\mathsf{m =\:\frac{8 - 4}{-4 -(-2)}\:=\:\frac{4}{-4+2}\:=\Frac{4}{-2}\:=\:-2}[/tex]
Hence, the slope of the line is: m = -2.
Y-intercept:Next, we must solve for the y-intercept. Since it is the point where the graph crosses the y-axis, set x = 0 and solve for the value of y.
Use the slope, m = -2, and one of the given points, (-2, 4), and substitute these values into the slope-intercept form to solve for the value of the y-intercept, b:
y = mx + b
4 = -2(-2) + b
4 = 4 + b
Subtract 4 from both sides:
4 - 4 = 4 - 4 + b
0 = b
The y-intercept is: b = 0.
Linear Equation in Slope-intercept Form:Therefore, the equation of the line in slope-intercept form is:
y = -2x + 0 or y = -2x.
Find the value of n in (n, -4)In order to determine the value of n, substitute its corresponding y-coordinate, -4, and substitute into the equation in the previous step:
Set y = -4:
y = -2x
-4 = -2x
Divide both sides by -2 to solve for x:
[tex]\displaystyle\mathsf{\frac{-4}{-2}\:=\:\frac{-2x}{-2}}[/tex]
x = 2
Therefore, the value of n = 2.

Find the surface area and volume of the basketball. Round your answer to the nearest hundredth.
Answer:
Surface area: 277.59 in^2
Volume: 434.89 in^3
Step-by-step explanation:
Radius = C/(2*pi)
29.5/3.14 = 9.39
Radius = 9.39/2 = 4.7 in
A = 4 pi r^2
A = (4) (3.14) (4.7)^2
A = 277.59 in^2
Volume = (4/3) (pi)(r)^3
(4/3)(3.14)(4.7)^3
= 434.89 in^3
Answer:
Surface area: [tex]277.59[/tex] in^[tex]2[/tex]
Volume: [tex]434.89[/tex] in^[tex]3[/tex]
Explanation:
