Answer:
yes it look right like the one you have to do 2x+5=39
Answer:
f(x) = -3x + 12
Step-by-step explanation:
The chart could be represented like this:
x y
0 12
1 9
2 6
3 3
Suppose that f(x) = y
And substitute x values.
y = -3x + 12
"x = 0"
y = -3(0) + 12
y = 0 + 12
y = 12
"x = 3"
y = -3(3) + 12
y = -9 + 12
y = 3
From the results, it corresponds to the function.
Answer:
- 4 1/2 + 3 1/4
-9/2 + 13/4
the lcm is 4
-18/4 + 13/4
=-5/4
= -1 1/4
Step-by-step explanation:
12x40=480
You can first multiply 12x4=48 and then you could put a zero next to the 8
Answer:
<u>Proportional relationship formula:</u>
- y = kx, where k is the constant of proportionality
Use one of the ordered pairs to calculate the value of k
<h3>Company A</h3>
Point (2, 20)
The equation: y = 10h
<h3>Company B</h3>
Point (3, 20)
- 20 = k*3
- k = 20/3
- The equation: y = 20/3h
Company A has greater unit rate as 10 > 20/3
