Answer:

143

Step-by-step explanation:

-13x +39 - 4x +5 = 180

-17 x + 44 =180

- 17 x = 180 - 44

-17 x = 136

- X = 136 / 17

X = - 8

(-13 * - 8) + 39 = 104+39 = 143

(-4 * - 8) + 5 = 32 +5 = 37

In J, K is the midpoint. The coordinates of ) are (2, 2), and the coordinates of Kare (10, 11). What are the coordinates of L?

DiKsa [7]

Answer:

L(18, 20)

Step-by-step explanation:

In JL, K is the midpoint. The coordinates of J are (2, 2), and the

coordinates of K are (10, 11). What are the coordinates of L?

Solution:

If O(x, y) is the midpoint between two points A( $x_1,y_1$ ) and B( $x_2,y_2$ ). The equation to determine the location of O is given by:

$x=\frac{x_1+x_2}{2} \\\\y=\frac{y_1+y_2}{2}$

Since JL is a line segment and K is the midpoint. Given the location of J as (2, 2) and K as (10, 11). Let ( $x_2,y_2$ ) be the coordinate of L. Therefore:

$10=\frac{2+x_2}{2} \\\\20=2+x_2\\\\x_2=18$

$11=\frac{2+y_2}{2} \\\\22=2+y_2\\\\y_2=20$

Therefore L = (18, 20)

Krystal and Danielle each improved their yards by planting daylilies and ivy. They bought their supplies from the same store. Kr

Eddi Din [679]

Answer:

$9 and $6

Step-by-step explanation:

Let the cost of daylilies = d and ivy = i, then we have below equations:

d + 12i = 114
10d + 10i = 150

Simplify the second equation:

d + i = 15

Subtract the second equation from the first:

d - d + 12i - i = 114 - 15
11i = 99
i = 9, ivy costs $9

Now find d:

d = 15 - 9 = 6, daylilies cost $6
