Select all answers that have a value of 22?? Help..
Tom [10]

Let's plug in the variables one by one.

6g - 2h

plug in 5 for g and 4 for h

6(5) - 2(4)

multiply

30 - 8

subtract

→ 22

20g

plug in 2 for g

20(2)

multiply

40

2(g + 1)

plug in 10 for g

2(10 + 1)

add

2(11)

multiply

→ 22

4g + 5h

plug in 1 for g and 4 for h

4(1) + 5(4)

multiply

4 + 20

add

24

Therefore, the answers that have a value of 22 are 6g - 2h and 2(g + 1)

-2(3x+5y)=10 in slope intercept form
lesantik [10]

Answer:

The equation in the slope-intercept form is:

  • y = -3/5x - 1

Step-by-step explanation:

Given the equation

-2(3x+5y)=10

We know that the slope-intercept form of a line equation is

y = mx+b

where

  • m is the slope
  • b is the y-intercept

Writing the equation in slope-intercept form

-2(3x+5y)=10

-6x -10y = 10

Add 6x to both sides

-6x -10y + 6x = 10 +  6x

-10y = 10 + 6x

Divide both sides by -10

-10y / -10 = (10 + 6x) / -10

y = -3/5x - 1

Thus, the equation in the slope-intercept form is:

  • y = -3/5x - 1
