Answer:
9
Step-by-step explanation:
if you mean -3.2x+9 then the answer is 9 because you plug in 0 into x and solve the equation, you get the x intercept
Answer:
<em>Yes, this is a linear function because the rate of change is constant</em>
Step-by-step explanation:
<u>Linear Functions</u>
We can recognize a linear relation between variables x and y when they can be represented by a formula like
y=mx+b
Where m is the rate of change and it has a constant value. More specifically, a proportional relationship is a special case where b=0, meaning that every value of y divided by the corresponding value of x, is constant.
The situation described in the question says a bathtub is being filled at a rate of 4 liters per minute. It means that every minute, 4 liters are constantly being added to the existing quantity. This is a constant rate of change, so the correct answer is
"Yes, this is a linear function because the rate of change is constant"
Answer:
Y=0.2
X=0.9
Step-by-step explanation:
-6x+5y=1
+6x -> 5y=1 -> y=0.2
6x+4y=-10
+6x -> 12x+4y=-10
12x+4*0.2=-10
12x+0.8=-10
-0.8
12x=-10.8
x=0.9
Answer:
B.
y = $0.79x + $46.88
Step-by-step explanation:
total cost of bill = flat rate plus cost per mile times miles driven
y = $46.88 +$0 .79 *x
