Answer:
O No
Explanation:
Given equation: y = 13x + 12
To check if (2, 8) is a solution of the given equation.
Substitute x and y value in equation and check if it is true.

(x, y) = (2, 8)

simplify

This following statement is false and hence (2, 8) is not a solution.
Answer:
Step-by-step explanation:
simplify (5-3)
PEMDAS= parentheses- e -MULTIPLY- DIVIDE - ADD- SUBTRACT
2(5-3)2+62
(2*2)2+62
8+62
70
Answer:
R1 = {(1, 7) (2, 7) (4, 7) (6, 7)}
R3 = {(x, y) (y, z) (z, t) (t, v)}
R1 and R3 are functions because first element in the ordered pair is not repeating, i.e they have unique images
26+26=52 which is the side lengths.
116-52=64 which is the other side lengths together. So one side length 32. 32+32+26+26=116
First multiply them all by 8
2x - 1 = 7 + 4x
Subtract 2x
-1 = 7 + 2x
Subtract 7
-8 = 2x
Divide by 2
X = -4
