Answer: (2, 5)

Step-by-step explanation:

y = 2x + 1 y = 4x − 3

Eliminate the equal sides of each equation and combine.

2x + 1 = 4x − 3

Solve 2x + 1 = 4x − 3 for x.

Move all terms containing x to the left side of the equation.

Subtract 4x from both sides of the equation.

2x + 1 − 4x = −3

Subtract 4x from 2x.

−2x + 1 = −3

Move all terms not containing x to the right side of the equation.

Subtract 1 from both sides of the equation.

−2x = −3 − 1

Subtract 1 from −3.

−2x = −4

Divide each term by −2 and simplify.

x = 2

Evaluate y when x = 2.

Substitute 2 for x. y = 4 (2) − 3

Simplify 4 (2) − 3.

Multiply 4 by 2.

y = 8 − 3

Subtract 3 from 8.

y = 5

The solution to the system is the complete set of ordered pairs that are valid solutions.

(2, 5)

The result can be shown in multiple forms.

Point Form:

(2, 5)

Equation Form:

x = 2, y = 5

Heyo! I need some help, please. What is the x coordinate if (x, 17) is on a line that passes through the points (1, 2) and (-1,
expeople1 [14]

Answer:

  • x = 4

Step-by-step explanation:

<u>The line with points (1,2) and (-1,-8). Work out its equation.</u>

  • y = mx + b

<u>The slope is:</u>

  • m = (-8 - 2)/(-1 - 1) = -10/-2 = 5

<u>To find the y intercept, substitute x and y-xoordinates of point (1,2):</u>

  • 2 = 5(1) + b
  • b = 2 - 5
  • b = -3

<u>The line is:</u>

  • y = 5x - 3

<u>Point (x, 17), substitute y-coordinate and solve for x</u>

  • 17 = 5x - 3
  • 5x = 17 + 3
  • 5x = 20
  • x = 20/5
  • x = 4

Parker was able to pay for 60% of his college tuition with his scholarship. The remaining $10,000 he paid for with a student loa
irga5000 [103]

Answer: The cost of Parker's tuition was $25000

Step-by-step explanation:

Let x represent the cost of Parker's tuition.

Parker was able to pay for 60% of his college tuition with his scholarship. This means that the amount of his college tuition that he was able to pay is 60/100 × x = 0.6×x = 0.6x

The remaining $10,000 he paid for with a student loan. The amount remaining is x - 0.6x = 0.4x. This means that

0.4x was paid with a student loan. Therefore,

0.4x = 10000

x = 10000/0.4 = $25000

The number of cars at a car dealership is reduced by 10% in the first sales quarter of the year. If the number of cars decreased
Sphinxa [80]

Answer:

  • B) 28%

=================

Let the initial price be x.

After the first sales quarter the price is reduced by 10% and became:

  • x - 10% =
  • x - 0.1x =
  • 0.9x

After the second sales quarter the price is reduced by 20% and became:

  • 0.9x - 20% =
  • 0.9x - 0.2*0.9x =
  • 0.9x - 0.18x =
  • 0.72x

The decrease over the two quarters is:

  • x - 0.72x =
  • 0.28x

This is equivalent of 28%, hence the <u>correct answer choice</u> is B.
