Answer:
False
Step-by-step explanation:
Answer:

Step-by-step explanation:
The equation given is 
and also we have that
, thus:

------------
I think the question is missing which variable is defined as
, so I will solve for
since is the only other variable in the equation.
substituting
into
:

and we solve for m:

m is equal to 18.
I solved it on paper & took a pic ^ here ya go!
Answer:
28+104 = 132cm^2
Step-by-step explanation:
We can find the area of this figure by breaking it into two separate pieces. The top is a rectangle and the bottom is a trapezoid.
A rectangle = l*w = 7*4 = 28 cm^2
A trapezoid = 1/2 (b1+b2) *h = 1/2 (19+7) *8 = 1/2 (26)*8 =104 cm^2
Add these areas together
28+104 = 132cm^2
Answer:
The lines are perpendicular.
Step-by-step explanation:
If the lines are parallel, then the slopes are equal
If the lines are perpendicular, then the slopes are negative reciprocals
If neither of the above occur, then the lines are neither parallel or perpendicular.
y = 2x + 3 is in slope-intercept form, so the slope = 2
2y + x = 6
Solve for y: 2y = -x + 6
y = -1/2(x) + 3 so the slope = -1/2
2 and -1/2 are negative reciprocals, so the lines are perpendicular.
Note: Negative reciprocals have a product of -1. 2(-1/2) = -1
