Answer:
$ 2,050
Step-by-step explanation:
Earnings last year : x
0.4(x + 200) = 900
(x + 200) =900/0.4
x + 200 = 2250
x = 2250 - 200
x = $2,050
Let's put the chart into ordered pairs:
(x, y)
(2,1)
(3,4)
(3,3)
(4,2)
(5,5)
In bold, we see that there are two y-values at x=3. This means that this relation fails the vertical line test (two points on the same verticle line). This is not a function.
The answer options may be mis-written.
The answer is no, because one x value corresponds to more than one y-value.
First:
F=m.a
=4*7
=28N
Second:
F=m.a
28=m.2. (force is constant,so F=28N)
28/2=m
m=14kg.
It is 3. Because a square root is anything times itself to make an answer. For example:
