Answer:

The x-coordinate of the solution to this system of equations is 2

Step-by-step explanation:

we have

3x-y=2 ------> equation A

x+y=6 ------> equation B

Adds equation A and equation B

3x-y=2\\x+y=6\\--------\\ 3x+x=2+6\\4x=8\\x=2

<span>3x − y = 2

y = 3x - 2

x + y = 6

x + 3x - 2 = 6

4x - 2 = 6

4x = 6 + 2

4x = 8

x = </span>\frac{8}{4}

x = 2

Hence, the x co-ordinate is 2.

What value of x makes f(x) = -2 if f(x) = 3.4x - 7.1
enyata [817]

Option C

For x = 1.5 we get f(x) = -2

<em><u>Solution:</u></em>

Given function is:

f(x) = 3.4x - 7.1

We have to find the value of "x" so that f(x) = -2

Substitute f(x) = -2 in given function

-2 = 3.4x - 7.1

Solve for "x" by moving the constants to one side and variables to other side

3.4x = -2 + 7.1\\\\3.4x = 5.1\\\\ \text{Divide both the sides of equation by 3.4 }\\\\x = \frac{5.1}{3.4}\\\\x = 1.5

For x = 1.5 we get f(x) = -2

We can verify by substituting x = 1.5 in given function

f(1.5) = 3.4(1.5) - 7.1\\\\f(1.5) =5.1-7.1\\\\f(1.5) = -2

Thus for x = 1.5 we get f(x) = -2

Determine the solution to the system of equations graphed below and explain
lawyer [7]

If x - 4 ≥ 0, then |x - 4| = x - 4, so

G(x) = F(x)   ⇒   3x + 2 = (x - 4) + 2

⇒   3x + 2 = x - 2

⇒   2x = -4

⇒   x = -2

Otherwise, if x - 4 < 0, then |x - 4| = -(x - 4), so

G(x) = F(x)   ⇒   3x + 2 = -(x - 4) + 2

⇒   3x + 2 = -x + 6

⇒   4x = 4

⇒   x = 1

However,

• when x = -2, we have

G(-2) = 3(-2) + 2 = -4

F(-2) = |-2 - 4| + 2 = 8

• when x = 1, we have

G(1) = 3(1) + 2 = 5

F(1) = |1 - 4| + 2 = 5

so only x = 1 is a solution to G(x) = F(x).

Can somebody please help me!!
xxMikexx [17]
So to solve for x, you'll need to combine all the angles and equal it to 720, and from there we can solve.

120+100+120+x+10+120+x=720

Combine like terms to get 2x+470=720

Subtract 470 on each side to get 2x=250

Then just divide on each side and you'll get x=125


To find the value of the (x+10) angle, just substitute 125 for x and solve.

125+10=135
