Answer:
-5
Step-by-step explanation:
-7u+9=2
-7u=2-9
-7u=-7
7u=7
u=7/7
u=1
3(1)-8=3-8=-5
Answer:
C) Neither
Step-by-step explanation:
y = -1/4x + 8
-2x + 8y = 4
To compare the slopes we need to convert the second equation to the same form as the first ( that is slope/intercept form).
-2x + 8y = 4
8y = 2x + 4
Divide through by 8:-
y = 1/4 x + 1/2
The slope of the first line is -1/4 and its 1/4 for the second line.
If the slopes were the same the lines would be parallel and if they were perpendicular their product would be = -1.
The product is 1/4 * -1/4 = -1/16
So they are neither parallel nor perpendicular.
Answer:
Step-by-step explanation:
Convert 2y=-3x+2 into y=mx+b form


Y intercept is 1, slope is -3/2

Answer:
I really cant find one...Ive tried all of them on the clacutaor but the closest one seems to be number 4
Step-by-step explanation:
Answer:
x = 12.
Step-by-step explanation:
This is an equilateral triangle so all the sides are congruent.
So 4x - 10 = 3x + 2
4x - 3x = 2 + 10
x = 12.
