Answer:

m = -4

Step-by-step explanation:

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

m = (-7 - -19)/(-2 - 1) = (-7 + 19)/(-3) = 12/-3 = -4

Suppose PR = 54, solve for QR<br> 4x-1<br> 3x-1<br> P<br> R

Svet_ta [14]

Answer:

$QR = 23$

Step-by-step explanation:

P, A, and R are collinear.

PR = 54

$PQ = 4x - 1$

$QR = 3x - 1$

To solve for the numerical length of PR, let's generate an equation to find the value of x.

According to the segment addition postulate:

$PQ + QR = PR$

$(4x - 1) + (3x - 1) = 54$ (substitution)

Solve for x

$4x - 1 + 3x - 1 = 54$

Combine like terms

$4x + 3x - 1 - 1 = 54$

$7x - 2 = 54$

Add 2 to both sides

$7x - 2 + 2 = 54 + 2$

$7x = 56$

Divide both sides by 7

$\frac{7x}{7} = \frac{56}{7}$

$x = 8$

$QR = 3x - 1$

Plug in the value of x into the equation

$QR = 3(8) - 1 = 24 - 1$

$QR = 23$

Lace edging is sold by the foot for $0.80 or by the foot for $1.99. Which is more expensive

vampirchik [111]

Answer:

$1.99 is more expensive.

Step-by-step explanation:

Given:

One type of lace edging cost $0.80 per foot

Another type of lace edging cost $1`.99 per foot.

We need to find which is more expensive.

In $0.88 where one's place is 0.

In $1.99 where one's place is 1.

By comparing the one's place obviously $1.99 more expensive.

Hope you will understand the concept.

Thank you.
