The equations of the perpendicular lines are: y = 1/2x + 6, y = 15, y = -x - 2, y = 6x + 3 and y = 1/3x - 4

<h3>How to determine the equations?</h3>

When a linear equation is represented as:

Ax + By = C

The slope (m) is:

m = -A/B

When the linear equation is represented as:

y = mx + c

The slope is m

A line perpendicular to a linear equation that has a slope of m would have a slope of -1/m

Using the above highlights, the equations of the lines are:

<u>6. y = -2x + 5; (2, 7)</u>

The slope is:

m = -2

The perpendicular slope is:

n = 1/2

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = 1/2(x - 2) + 7

Evaluate

y = 1/2x - 1 + 7

This gives

y = 1/2x + 6

<u>7. y = -5; (11, 15)</u>

The slope is:

m = 0

The perpendicular slope is:

n = 1/0 = undefined

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = 15

<u>8. Graph ; (-12, 10)</u>

The slope is:

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

Using the points on the graph, we have:

m = (2 - 3)/(3 - 4)

m = 1

The perpendicular slope is:

n = -1

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = -1(x + 12) + 10

y = -x - 12 + 10

Evaluate

y = -x - 2

<u>9. y = -1/6x + 1; (-2, -9)</u>

The slope is:

m = -1/6

The perpendicular slope is:

n = 6

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = 6(x + 2) - 9

Evaluate

y = 6x + 12 - 9

This gives

y = 6x + 3

<u>10. 6x + 2y = 14; (12, 0)</u>

The slope is:

m = -6/2

m = -3

The perpendicular slope is:

n = 1/3

The equation of the perpendicular line is:

y = n(x - x1) + y1

This gives

y = 1/3(x - 12) + 0

Evaluate

y = 1/3x - 4

Hence, the equations of the perpendicular lines are: y = 1/2x + 6, y = 15, y = -x - 2, y = 6x + 3 and y = 1/3x - 4

Answer:

  1. 18x - 9 = 72
  2. 3(6x - 3) = 72
  3. x = 45

Step-by-step explanation:

Apply the distributed property:

  1. Apply the distributed property: 3/5 × 30x = 18x, 3/5 × 15 = 9
  2. Re-write the equation: 18x - 9 = 72
  3. 18x - 9 = 72 is an option listed, so that's one of the answers.

See the other options:

  1. Another option that looks like it could be the answer is 3(6x - 3) = 72
  2. Apply the distributed property like we did above, so it now looks like this: 18x - 9 = 72
  3. This is the same as what we got above, so it is also an answer.

Solve:

  1. Add 9 to each side, so it now looks like this: 18x = 81
  2. Divide each side by 18 to cancel out the 18 next to x. It should now look like this: x = 4.5
  3. x = 45 is an option listed, so that's one of the answers.

I hope this helps!

Solve the equation 6(2x + 4)2 = (2x + 4) + 2.
Lemur [1.5K]

Answer:

x = -21/11

Step-by-step explanation:

6(2x + 4)2 = (2x + 4) + 2

12(2x +4) = 2x + 4 + 2

24x + 48 = 2x +6

22x = -42

x = -21/11

Show your work everywhere you can!<br><br> solve for x. <br><br> c.x/5-12=48
Keith_Richards [23]
Remember you can do anything to an equation as long as you do it to both sides

x/5-12=48
add 12 to both sides
x/5+12-12=48+12
x/5+0=60
x/5=60
multiply bot sides by 5/1
5x/5=60 times 5
x times 5/5=300
x times 1=300
x=300

jeka94

Answer:

50-50 chance I suppose (1/2 or 5/10) or 40% to 60% percent chance

Step-by-step explanation:

He can guess all of the questions and get all of them right, and it is a possibility that he can also get all of them wrong. So I say, 50-50. I can't lie, I'm having trouble with probability as we speak.

The slope y intercept form of y+5=2 (x+3)
leva [86]
Answer :
Y= 2x+1

Explanation :
Y + 5 = 2 (x+3)
Multiply parenthesis by 2
Y + 5 = 2x +6
Move constant to the right
Y = 2x + 6 -5
Subtract the numbers
y= 2x + 1
And the answer should be
y= 2x + 1
