Answers

Answer:

-2

Step-by-step explanation:

The two angle are internal alternate relative to the two parallels, so they have the same measure.

[tex]-8x+8 = -6x+20\\-2x=12 \rightarrow x = -2[/tex]

Answer:

x = -6

Step-by-step explanation:

The two angles given are alternate angles - this means they are equal. Therefore:

-8x + 8 = -6x + 20

We can solve this by first putting all the x's on one side and the numbers on the other side:

-8x + 6x = 20 - 8

Now we can simplify both sides down:

-2x = 12

Finally divide both sides by -2 to get x on its own:

x = -6

Which equation can be used to describe the relationship between x and y shown in the table below?

Answers

Answer:

y = 3x/2 + 24

Step-by-step explanation:

y = ax + b

⇒ 6 = -12a + b

9 = -10a + b

⇒ 2a = 3, a = 3/2

⇒ b = 24

⇒ y = 3x/2 + 24

Find MP.
Segment addition

Answers

Answer:

MP  = 29

Step-by-step explanation:

MP = 5y + 9

MP = MN + NP

MP = 17 + 3y

Step 1 - As both equations are equal to MP:

3y + 17 = 5y + 9

Step 2 - Subtract 9 from both sides to isolate the 5y:

3y + 17 - 9 = 5y + 9 - 9

3y + 8 = 5y

Step 3 - Subtract 3y from both sides:

3y + 8 - 3y = 5y - 3y

8 = 2y

Step 4 - Divide both sides of the equation by 2:

[tex]\frac{8}{2} = \frac{2y}{2}\\4 = y[/tex]

Step 5 - Plug known variable y back into the equation:

5y + 9 = MP

5(4) + 9 = MP

20 + 9 = MP

MP  = 29

Write the equation of a line that is perpendicular to the given line and that passes through the given point.

y= 2/3x + 9; (–6, 5)
A. y= 2/3x + 9
B. y= -2/3x + 1
C. y= -3/2x - 4
D. y= -3/2x + 3/2

Answers

Answer:

B

Step-by-step explanation:

I had this question before

Answer:

C. y= -3/2x - 4

Step-by-step explanation:

Option 2, y=-3/2x-4

Step-by-step explanation:

Solve with the point-slope formula: y-y1=m(x-x1). The line is perpendicular, meaning the slope of the new equation will be the oppposite reciprocal of the original slope.

First, we need to rewrite the original equation into standard form.

2x-3y=13

-3y=13-2x

y=-13/3+2/3x

From this, we can see that the slope here is 2/3. Since the line we're looking for is perpendicular, the opposite reciprocal of that slope is -3/2.

Now, we can plug in the coordinates we have into the formula (-6, 5), along with our slope (-3/2).

y-(5)=-3/2(x+6)

y-5=-3/2x-9

y=-3/2x-4

And to check, we can just plug the coordinates into our new equation:

Check:

(5)=-3/2(-6)-4

5=9-4

5=5
