Roland hires a mechanic to do some work. He pays y dollars per hour for a 3-hour job plus $48 in replacement parts. The total cost comes to $200. Please round to the nearest cent.

Create an equation that can be used to find the amount, in dollars, the mechanic charges per hour.

Answers

So, the variable here is y: the amount of dollars per hour of work. We already know how many hours (3), the additional costs (48), and the total cost (200). What we need to do is put this into an equation. So we have number of hours times hourly rate plus additional costs:
3y + 48 = 200

In order to solve for y, this is what you have to do:
3y + 48 = 200 (subtract 48 from both sides)
3y = 152 (divide by 3 on both sides)
y = 50.666666
round to the nearest cent and you’d get a final answer of:
50.67

Which of the following lines is parallel to -5/7x-2

Answers

Answer:

The equation of a line is written in the form y=mx+b. “m” is the slope and “b” is the y-intercept. Parallel lines are lines which have the same slope but can have different y-intercepts. So, the equations that would be parallel to the given equation would have a slope of -5/7 and ANY y-intercept.

assume (-2,0) and (3,0) are the x intercepts of y=f(x). find the x intercepts of g(x)= f(x-3)

Answers

The intercepts of a graph are the points the graph crosses the x-axis

The x-intercepts of [tex]\mathbf{g(x) = f(x - 3)}[/tex] are (-5,0) and (0,0)

For y = f(x), we have

[tex]\mathbf{(x,y) = (-2,0)\ (3,0)}[/tex]

For g(x) = f(x - 3), we have:

[tex]\mathbf{(x-3,y) = (-2-3,0)\ (3-3,0)}[/tex]

[tex]\mathbf{(x-3,y) = (-5,0)\ (0,0)}[/tex]

Recall that:

[tex]\mathbf{g(x) = f(x - 3)}[/tex]

Hence, the x-intercepts of [tex]\mathbf{g(x) = f(x - 3)}[/tex] are (-5,0) and (0,0)

Marcus builds 2,744 kites for a 14-day summer kite festival.

He plans to give away about the same number of kites each day.

He gives away 492 kites the first two days. Did Marcus stick to his plan?

Use estimation to explain. Show your work.

Solution

Answers

Answer:

please use the solution

Step-by-step explanation:

solution: 492÷2=246

2744÷14=196

246≥196

so thus Marcus doesn't stick to his plan because he didn't have the number of kites.

No, Marcus did not stick to his plan.

What is Unit rate?

A unit rate means a rate for one of something.

Given that, Marcus builds 2,744 kites for a 14-day summer kite festival.

He plans to give away about the same number of kites each day.

He gives away 492 kites the first two days,

According to his plan, he should sell = 2744/14 = 196

But he sold = 492/2 = 246 each day

Hence, he sold more kites than his planning, so he did not stick to his plan.

What is the slope of the equation graphed on the coordinate plane?

Answers

Answer: slope = 0

Explanation:

Any horizontal line always has a slope of 0. The slope is rise/run. Horizontal lines don't have a rise or fall, so rise = 0. The run can be any nonzero value you want.

You can also use the slope formula

m = (y2-y1)/(x2-x1)

and you can pick any two points from that blue line.

find the values of a,b,and c

Answers

Answer:

a = 1

b = -6

c = 0

Hope this helps!

Answer:

a = 1

b = -6

c = 0

Step-by-step explanation:

A standard quadratic equation is set up in the form ax^2+bx+c. So, for this equation, "a" is the value before the x^2, which is 1, "b" is the value before the x, which is -6, and since there is no "c" value, that means c is 0.

Question Write in slope-intercept form an equation of the line that passes through the given points. (−1, −1), (1, 5)

Answers

Answer:

y = 3x + 2

Step-by-step explanation:

Slope-intercept form looks like this: y=mx+b

First, you must do⤵⤵⤵:

[tex] \frac{y _{2} - y _{1} }{x _{2} - x _{1} } = \frac{rise}{run} = slope[/tex]

y: 5 - (-1) = 5 + 1 = 6

x: 1 - (-1) = 1 + 1 = 2

6/2 = 6 ÷ 2 = 3

Slope = 3 (This automatically means 3/1 btw)

Now, from the first coordinates (-1, -1), go upwards 3 units and to the right 1 unit. Do this until you get to the second point. (Here it is graphed for you, above⤴⤴⤴) You can see that the y-intercept is 2.

Now that you know slope is 3, and y-intercept is 2, all you have to do is put it in slope-intercept form. Answer is y = 3x + 2

Hope this helps :)

Step-by-step explanation:

How many solutions are there for the system of equations containing y = x-5 and
2x - 2y = 8, and why?

Answers

Answer:

None, because 0 cannot equal 1.

Step-by-step explanation:

y = x - 5

2x - 2y = 8

First let's solve for y in the bottom equation

Subtract 2x form both sides

2x - 2y = 8

- 2x - 2x

-2y = 8 - 2x

Divide both sides by -2

-2y/-2 = (8 - 2x)/-2

y = x - 4

Now substitute the y's in both equations

x - 4 = x - 5

Move like terms to one side by adding 4 to both sides

x - 4 = x - 5

+ 4 + 4

x = x - 1

Subtract x from both sides

x = x - 1

- x - x

0 = 1

Zero cannot equal one, meaning this system of equations is invalid and has no solutions.
