Step-by-step explanation:
5.
a.
Variable y is independent
Variable x is dependent
b.
f_f(x)=0.063*x+0 . Computer's best guess is this given the points. Needing further information. [DO NOT TRUST THIS ANSWER] (for b.)
c.
Unit rate = a rate for one of something. Calculate how much y, cost increases for one fluid ounces, x.
d.
Cost, y = 2.
6.
a.
y = [UNABLE TO FIND]
b.
Let's say user chooses a random area of 6. 6 = 1/2bh. We know, in accordance to the table that the height, x correlating to area, 6 is 2.
1/2 * 2 = 1
1 * b = 6, b = 6.
7.
a.
y = 64x
In accordance to the graph, an increase of 128 miles takes 2 hours. That means in 1 hour, there is an increase of 64 miles.
b.
64 miles per hour.

When x = 6.4, y=117, therefore
15*6.4 + b = 117
b = 117 - 96 = 21
Confirm this value by checking (6.6, 120).
15*6.6 + 21 = 120 (Correct)
Answer: b = 21
Answer:Answer:
f(-2) = 2
f(0) = 3
f (4) = -1
Step-by-step explanation:
The equation of the straight line passing through the points (0,3) and (-4,1) is
⇒ 2(y - 1) = x + 4
⇒ 2y - 2 = x + 4
⇒ 2y = x + 6
⇒
Again, the equation of the line passing through the points (0,1) and (4,-1) is
⇒ - 2 ( y + 1) = x - 4
⇒ - 2y = x - 2
⇒
Therefore, the function is defined as
for x ≤ 0 ........... (1) and
for x > 0 ............ (2)
Therefore, f(-2) = 2 from equation (1).
f(0) = 3 from equation (1)
And f (4) = -1 from equation (2). (Answer)
Step-by-step explanation:
I believe the answer is (7,-1) after you plot the point and draw a line connecting then you can see the point on the line.
