Answer:
See below
Step-by-step explanation:
we have f(x) = -(x-7) + 3
and we want to find f(4)
essentially, f(4) means that the input is 4 and to find the output we plug in the value of the input where ever x is and evaluate.
So for f(x) = -(x-7) + 3
To find f(4) we replace all x's with 4
f(4) = -(4-7) + 3
we now evaluate
==> subtract 7 from 4
f(4) = -(-3) + 3
==> apply two negative rule ( basically if there are two negative signs they cancel out and the number turn positive )
f(4) = 3 + 3
==> add 3 and 3
f(4) = 6
Answer:
-1/5
Step-by-step explanation:
slope can be found with the equation found in the image.
assign each coordinate with the according variable
x1 = 3 x2 = -7 y1 = 2 y2 = 4
and input the values accordingly.
4 - 2 / -7 - 3 PEMDAS (order of operations)
= 2/ -10 Simplify
= 1/ -5
=-1/5
M is also the midpoint of the diagonal BD.
In a parallelogram, the diagonals are perpendicular bisectors of each other. That means that midpoint of one of the diagonals is also the midpoint of the other diagonal.
Angle P is equal to 74. Do you need to know the working?
