Lines are perpendicular if the slope of one is the negative reciprocal of the other. In this case the slopes are -8/3 and 8/3, so while negative they are not reciprocal. So no, the two lines intersect but are not perpendicular.
Step-by-step explanation:
2x + 7x - 10 = 180° because these rwo angles are supplementary
10x - 10 = 180°
10x = 190° divide both sides by 10
x = 19
measure of angle on the right:
8x - 10 ➡ 8 × 19 - 10 = 142°
measure of angle on the left:
2x ➡ 2 × 19 = 38°

Answer:
No. This graph does not represent a function.
Step-by-step explanation:
Functions have one output for each input. For example;
(1, 3) (2, 6) (3, 9) etc.
This is not a function because the same input has multiple outputs;
(-5, 1) (-5, 2) (-5, 3) etc.
49 because he can play all the cards at the same time if he can, also he can play his cards between 1 and 7 times so you would multiply 7 by its self.
