Problem 1
We replace every copy of x with 4c and simplify like so:
f(x) = 8 - 5x
f(4c) = 8 - 5*4c
f(4c) = 8 - 20c is the answer
This is equivalent to -20c+8.
====================================================
Problem 2
Same idea as before, but this time we'll plug in x = 2-k
Each x gets replaced with (2-k)
f(x) = 8 - 5x
f(2-k) = 8 - 5(2-k)
f(2-k) = 8 - 10 + 5k
f(2-k) = -2 + 5k
This is the same as saying 5k - 2.
====================================================
Problem 3
The steps are similar to earlier.
f(x) = 8 - 5x
f(4p+3) = 8 - 5(4p+3)
f(4p+3) = 8 - 20p - 15
f(4p+3) = -7-20p
This is the same as writing -20p - 7.
Answer:
28
Step-by-step explanation:
Answer:
8) Parallelogram.
10) Point W.
Step-by-step explanation:
8) Give another name of plane V.
As shown the plane represents A flat shape with 4 straight sides where opposite sides are parallel and also opposite sides are equal in length.
So, plane V represents parallelogram
10) Name a point that is not coplanar with R, S and T.
Coplanar points are the points which all lie in the same plane.
So, as shown:
R, S and T are coplanar points, they all lie in the plane V
So, the point which doesn't lie in the plane V is the point W
So, <u>the point W</u> is not coplanar with R, S and T.
Answer:
-3/4
Step-by-step explanation:
To find the slope, plug the coordinates into the slope formula.
y2 - y1 / x2 - x1
4 - (-2) / -7 - 1
6 / - 8
-3/4
Answer:
g(2) =7
Step-by-step explanation:
g (x)= 3/2x+4
Let x = 2
g (2)= 3/2 *2+4
= 3 +4
= 7
