Answer:
c - 12ft
Step-by-step explanation:
The answer is x = -2 +- sqrt 7
You would do 22x8 and that would be your answer of 176! I hope this helped! :D
1/5÷2/3
to divide by a fraction flip the second and multiply
=1/5×3/2
multiply tops by tops and bottoms by bottoms
=3/10
so 3/10 cm per year
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.
