Y= -2x=20 All you have to do is use the equation y=mx+b. For the y you plug in 8, the m= -2, plug in x which is 6 and since you're finding the b you just put +b at the end. So it looks like this, 8=-2(6)+b.

Now you solve it... Just drop the 8 and multiply -2 x 6 which ='s -12. Then you just drop the +b so the equation now looks like this, 8=-12+b. You'll notice there's a -12 so you just simply add 12 to both sides and your answer should be 20=b.

Knowing m=-2, your answer should be y= -2x+20.

B) 2x+y=20

Step-by-step explanation:

Answer from: Quest

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x : 0 5

y : 5 0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x : 0 2

y : -1 4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.

Answer from: Quest

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
