If the point (5, k) lies on the line represented by the equation 2x + y = 9, the value of k is
Paladinen [302]

Answer:

<h2>k = -1</h2>

Step-by-step explanation:

We have the point (5, k) and the equation 2x + y = 9.

Put the coordinates of the point ot the equation:

x = 5, y = k

2(5) + k = 9

10 + k = 9         <em>subtract 10 from both sides</em>

10 - 10 + k = 9 - 10

k = -1

On a coordinate plane, triangle J K L has points (negative 2, 1), (0, 3), and (2, negative 1). Reflect the figure over the line
svetlana [45]

Answer:

J'(2, 1)

K'(0, 3)

Step-by-step explanation:

On a coordinate plane, coordinates of the points J, K and L are (-2, 1), (0, 3) and (2, -1) respectively.

If we reflect these points over the line x = 0 or y-axis, rule to be followed is

(x, y) → (-x, y)

Only sign of x coordinates get changed while y coordinates remain the same.

Following this rule coordinates of the images of J' and K' will be

J(-2, 1) → J'(2, 1)

and K(0, 3) → K'(0, 3)

Nastasia [14]

Answer:

Step-by-step explanation:

A. c=30+45(h)

B. 30+45(6.5)= 30+292.50= 322.50

He pays a set rate of $30.00. He also pays a charge of $45 an hour for work. The electrician worked 6.5 hours. Take the 45 and multiply that by the 6.5 hours to get $292.50. Take that charge and add the set fee of $30. You get a total of $322.50 he will pay for the electrician.
