Answer:

C

Step-by-step explanation:

From the midsegment theorem we can conclude that

QR = \frac{1}{2} NP

Using QR = 3x + 2 and NP = 2x + 16, then

3x + 2 = \frac{1}{2}(2x + 16) = x + 8 ( subtract x from both sides )

2x + 2 = 8  ( subtract 2 from both sides )

2x = 6 ( divide both sides by 2 )

x = 3

As a check

QR = 3x + 2 = 3(3) + 2 = 9 + 2 = 11

NP = 2x + 16 = 2(3) + 16 = 6 + 16 = 22

Thus QR is one half NP is confirmed

Answer:

<h2>C.  QR=1/2NP  ;  x=3</h2>

Step-by-step explanation:

QR=1/2NP ⇔ NP=2QR ⇔ 2x+16=2(3x+2) ⇔ 2x+16=6x+4 ⇔ 12=4x ⇔ x=3

blagie [28]

Answer:

12

Step-by-step explanation:

x will be the age of her younger brother

 34 = 2x + 10

She is ten more than twice his age

 34 = 2x + 10

- 10         - 10

Then she twice his age

24 = 2x

÷2   ÷2

So his age is 12

x = 12

HELP HELP ASAP THANKS
mylen [45]

Answer:

Step-by-step explanation:

the range is written as (min y value, max y value)

the domain is written as (min x value, max x value)

question 6

the min y value on the picture is -3, while the arrows point upward, so the max is infinity, so the domain is [-3,∞), with a bracket on -3 because -3 is included

[-3,∞)

question 7

the min x value is the leftmost point, which is at x = -3, while the max is the rightmost point at x = 3, and both are included in the domain so there should be brackets on both

[-3,3]

question 8

the arrow on the left points to the left and up infinitely, so the min is -∞, the arrow on the right points to the right and up infinitely, so the max x value is ∞

(-∞,∞)

question 9

the min value is the bottommost point at y = -2, and the arrow points upward infinitely so the max y value is ∞

[-2,∞)

question 10

the arrow on the left points to the left infinitely so the min x value is -∞, the arrow on the right points to the right infinitely so the max x value is ∞

(-∞,∞)

The equation of line AB is y 5x+ 1. Write an equation of a line paraliei to line AB in slope-intercept form that contains point
Alchen [17]

Answer:

The equation would be y = 5x - 15

Step-by-step explanation:

To find the equation to this line, we first have to note that parallel lines have the same slope. Since the original line has a slope of 5, we know that the new line will also have that slope. Then we can use the slope and the point in point-slope form and solve for y.

y - y1 = m(x - x1)

y - 5 = 5(x - 4)

y - 5 = 5x - 20

y = 5x - 15
