how do you solve for Y
problem #5
9514 1404 393
Answer:
y = 26
Step-by-step explanation:
You have already correctly solved for x, so you know that ...
m∠8 = 4(17)+10 = 78
Angle 12 is an alternate interior angle with respect to angle 8, so is congruent to angle 8.
m∠12 = m∠8
3y = 78
y = 78/3 . . . . divide by the coefficient of y
y = 26

Carlos picked one of four equations in the table to solve. Carlos correctly solved the equation he chose. His answer was x = 5.
Equation 1 6x + 40 = 82
Equation 2 12x- 1 = 2
Equation 3 2x + 21 = 31
Equation 4 18x+ 9 = 13
Which equation did Carlos choose to solve?
If the point of the preimage is (5,2) and the point of the image is (1,2), what RULE was applied to the preimage to obtain the image?
A) (x, y + 4)
B) (x + 4, y)
C) (x - 4, y)
D) (x, y - 4)
Explanation:
We have x = 5 turn into x = 1. We need to subtract 4 from the x coordinate to get this. Therefore x turns into x-4.
The y coordinate stays at y = 2 the entire time, so y isn't altered. We have y map to y.
Overall, the rule is [tex](x,y) \to (x-4, y)[/tex] which translates the point 4 units to the left.

Solve the following equation and justify each step by stating the property used or providing an explanation for each step 6x-9=8x11
Answer:
6x9=54 11x8=88
Step-by-step explanation:
i dont get it hope it helps
Answer: x= -10
Step-by-step explanation:
Let's solve your equation step-by-step.
6x−9=8x+11
Step 1: Subtract 8x from both sides.
6x−9−8x=8x+11−8x
−2x−9=11
Step 2: Add 9 to both sides.
−2x−9+9=11+9
−2x=20
Step 3: Divide both sides by -2.
−2x /-2= 20/-2
x=−10
Answer:
x=−10
