Solve for X Explain if possible :)

The two labeled angles are alternate interior angles, and as such, they are the same.

From this result you can build the equation

$15x-2 = 13x+2$

and solve it for x: subtract 13x from both sides to get

$2x-2=2$

and add 2 to both sides to get

$2x = 4 \implies x = 2$

Check: if we plug the value we found we have

$13\cdot 2 + 2 = 26+2 = 28 = 15\cdot 2 - 2 = 30-2$

So the angles are actually the same, as requested.

Which ordered pair represents the y-intercept of the graph of the equation y = -3x - 9?

Mnenie [13.5K]

------------------------------------------------------------------------------------------
Equation
------------------------------------------------------------------------------------------
y = -3x - 9

------------------------------------------------------------------------------------------
Option 1
------------------------------------------------------------------------------------------
If I substitute x = -9, I should get y = 0

When x = -9
y = -3 (-9) - 9
= 18 (I did not get 0, wrong)

------------------------------------------------------------------------------------------
Option 2
------------------------------------------------------------------------------------------
If I substitute x = -3, I should get y = 0
y = -3(-3) - 9
y = 9 - 9
y = 0 (Yes, I got 0, correct)

------------------------------------------------------------------------------------------
Option 3
------------------------------------------------------------------------------------------
If I substitute x = 0, I should get y = -3
y = -3 (0) - 9
y = 0 - 9
y = -9 (I did not get -3, wrong)

------------------------------------------------------------------------------------------
Option 4
------------------------------------------------------------------------------------------
If I substitute x = 0, I should get y = -9
y = -3 (0) - 9
y = 0 - 9
y = -9 (Yes, I got -9, correct)

------------------------------------------------------------------------------------------
Answer: (-3, 0) and (0, 9) are ordered pairs of the equation (Answer B, D)

larry,mary and terry each had a full glass of juice. larry drank 3/4 of his mary drank 3/8 of hers larry drank 3/4 of his terry

Katena32 [7]

3/4 is greater than 1/2

7/10 is greater than 5/10

and 3/8 is less the 4/8 (4/8=1/2)
