The lines s and t intersect at point R.<br><br> What is the value of y?<br><br> y = ____
ozzi
Assuming that the angles are congruent, then y = 29.
4y - 8 = 79 + y
4y = 87 + y             Add 8 to both sides
3y = 87                  Subtract y from both sides
y = 29

Use the given values to make a table of solutions.
bearhunter [10]

Answer:

Step-by-step explanation:

y = 2x

when x = 1

y = 2(1).....y = 2........so when x = 1, y = 2

when x = 2

y = 2(2)....y = 4 ......so when x = 2, y = 4

when x = 3

y = 2(3)....y = 6.......when x = 3, y = 6

when x = 4

y = 2(4).....y = 8.....when x = 4, y = 8

============================

y = 4x - 1

when x = -4

y = 4(-4) - 1.....y = -17.....so when x = -4, y = -17

when x= -3

y = 4(-3)- 1..... y = -13....so when x = -3, y = -13

when x = -2

y = 4(-2) - 1.....y = -9.....so when x = -2, y = -9

when x = -1

y = 4(-1) - 1....y = -5.....so when x = -1, y = -5

you can make the tables from this info...

your basically just subbing in ur value of x into the equation to find ur value of y

Write 2/3 with the denominator 12
Nataly_w [17]

Answer:

8/12

Step-by-step explanation:

First

12 divided by 3 = 4

Second

since 12/3=4 you multiply 3x4 to get 12 so what you do to the denominator you do to the numerator so 2x4=8

Last

so that would give you

2/3 = 8/12
