2x + 3y = 12
2x - y = 4
4y = 8
y = 2

2x - 2 = 4
2x = 6
x = 3

The coordinates are (3,2) and that is your answer :)

Which statement is true regarding the graphed functions?
Vladimir79 [104]

let's analyze each case to determine the solution

<u>case 1)</u> f(0) = 2 and g(–2) = 0

For x=0-----> find the value of f(0) in the graph-----> f(0)=4

For x=-2-----> find the value of g(-2) in the graph-----> g(-2)=0

therefore

the statement of the case 1) is false

<u>case 2)</u> f(0) = 4 and g(–2) = 4

For x=0-----> find the value of f(0) in the graph-----> f(0)=4

For x=-2-----> find the value of g(-2) in the graph-----> g(-2)=0

therefore

the statement of the case 2) is false

<u>case 3)</u> f(2) = 0 and g(–2) = 0

For x=2-----> find the value of f(2) in the graph-----> f(2)=0

For x=-2-----> find the value of g(-2) in the graph-----> g(-2)=0

therefore

the statement of the case 3) is true

<u>case 4)</u> f(–2) = 0 and g(–2) = 0

For x=-2-----> find the value of f(-2) in the graph-----> f(-2) is greater than 12

For x=-2-----> find the value of g(-2) in the graph-----> g(-2)=0

therefore

the statement of the case 4) is false

therefore

<u>the answer is</u>

f(2) = 0 and g(–2) = 0-------> this statement is true

Nastasia [14]
8x+10-2= 2x+44
8x+8= 2x+44
8x-2x= 44-8
6x= 36
x= 6

so A is the correct answer :)

Solve the equation: 10 = -4 + x
Sonja [21]
10= -4 + x    x=14 because you do the opposite of the sign you see in this case its a plus sign so you subtract -4 from ten and since the 4 is a negative and your subtracting you would add 4 I know this probably didn't help it sounds really confusing but I have hope that it did :)
