Please send help! I would be so grateful if someone could show the answer, with work!

Answers

Answer 1

Answer:

n = 25

Step-by-step explanation:

-2n + 15 = n - 60

Subtract 15 to both sides

-2n = n - 75

Subtract n to both sides

-3n = -75

Divide -3 to both sides

n = 25

Best of Luck!

Answer 2

Answer:

n=25

Step-by-step explanation:

-2n+15=n-60

-3n+15=-60

-3n=-75

n=25

Refering to the equation, tell how
you know g(x) = 2x² is a vertical
Ishrink of the PQE F(x) = x²

Answers

Answer:

  the scale factor is the vertical expansion factor.

Step-by-step explanation:

The scale factor of 2 in

  g(x) = 2·F(x)

means g(x) is a vertical expansion (not shrink) of F(x) — by a factor of 2.

_____

Additional comment

The equation g(x) could be considered to be ...

  g(x) = F(x·√2)

in which case g(x) could be interpreted as a horizontal shrink by a factor of (√2)/2. Squeezing a parabola horizontally has the same effect on its appearance as stretching it vertically.

Use the figure to the right to find the value of PT. T is the midpoint of PQ.
PT = 4x + 5 and TQ = 8x-7

Answers

Answer:

PT = 17

Step-by-step explanation:

Since T is the midpoint of PQ, then

PT = TQ , substitute values

4x + 5 = 8x - 7 ( subtract 4x from both sides )

5 = 4x - 7 ( add 7 to both sides )

12 = 4x ( divide both sides by 4 )

3 = x

Thus

PT = 4x + 5 = 4(3) + 5 = 12 + 5 = 17

Answer:

17

Step-by-step explanation:

since T is mid point of PQ

PT=TQ

[tex]4x + 5 = 8x - 7 \\ 5 + 7 = 8x - 4x \\ 12 = 4x \\ x = 12 \div 4 \\ x = 3 \\ [/tex]

so

[tex]pt = 4x + 5 \\ = 4(3) + 5 \\ = 12 + 5 \\ pt = 17[/tex]

A plumber charges $75 per hour and spends $30 a day on gasoline. Write an algebraic expression to represent his earnings for one day. Let x represent the number of hours the electrician works in one day.

Answers

Answer:

75(x)+30

Step-by-step explanation:

The algebraic expression to represent a plumber's earnings for one day is 75x - 30, where x is the number of hours.

What is an Expression?

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

A plumber charges $75 per hour and spends $30 a day on gasoline. Therefore, the total earnings and the total spending of the plumber is,

Total Earning = $75 × x

Total Spending due to gasoline = $30

Therefore, the net earnings of the plumber are,

Net Earning = Total Earning - Total spending

Net Earning = $75x - $30

What is distance?

Distance makes reference to the numerical calculation of how far away an object is from a specific location. It may also refer to a physical length or an assessment made in accordance with the criterion.

Therefore, a distance from X to Y can be swapped for a distance from Y to X. In addition to these facts, we can compute distance  by taking into account a number of variables, such as the speed and time required to travel a particular distance.

Additionally, speed is a measurement of how swiftly a body or thing moves from one location to another.

Given parameters:

Caroline's car used 16 gallons to travel 544 unit.

Caroline's car used 1 gallons to travel 544÷16 unit =34 unit.

Caroline's car used 9 gallons to travel 9×34 unit = 306 unit.

Hence, she  can travel 306 unit on 9 gallons.
