3g + h = 1 -2g + h= 10 ?

denpristay [2]

Answer:

{g,h} = {-9/5,32/5}

Step-by-step explanation:

h = 2g + 10

3g + (2g+10) = 1

[1] 5g = -9

5g = - 9

g = - 9/5

g = -9/

h = 2g+10

h = 2(-9/5)+10 = 32/5

{g,h} = {-9/5,32/5}

Which ordered pairs are soultions to the inequality y-2x<-3

Anna35 [415]

Answer:

(-3, 3/2)

Step-by-step explanation:

Given the inequality function y-2x<-3, to get the solution, we will need to find the x and y-intercept of the inequality function

y-intercept occurs at x = 0

Substitute x = 0 into the expression

y - 2(0) < -3

y < -3

Find the x-intercept by substituting y = 0 into the expression

0 - 2x < -3

-2x < -3

x > 3/2

Hence the ordered pair is (x, y) = (-3, 3/2)

Graphic image of the kite jklm after a reflection across the line Y= 1

olchik [2.2K]

Answer: see image

Step-by-step explanation:

Draw the line y = 1. Count how many units away the point is from that line. Move that point the same number of units in the opposite direction to create the reflection.

J is 2 units above y = 1. The new point is 2 units below y = 1. → (3, -1)

K is 3 units above y = 1. The new point is 3 units below y = 1. → (6, -2)

L is 5 units above y = 1. The new point is 5 units below y = 1. → (3, -4)

M is 3 units above y = 1. The new point is 3 units below y = 1. → (0, -2)
