Answer:
B and C
Step-by-step explanation:
We are going to look at each choice:
Let's look at choice A.
f(5)=1
f(5) means look at function f and then see which piece contains x=5.
5>1 so we are looking at for x=5 which gives you , this is not 1.
The answer is not A.
Let's look at choice B.
f(2)=4
f(2) means look at function f and then see which piece contains x=2.
2>1 so we are looking at for x=2 which gives you , so this is true that f(2)=4.
Let's look at choice C.
f(1)=5
f(1) means look at function f and then see which piece contains x=1.
1=1 which means we are using for x=1, so f(1)=5 which is what choice C says so choice C is true.
Let's look at choice D.
f(-2)=4
f(-2) means look at function f and then see which piece contains x=-2
-2<1 so we use for x=-2, so we get 2(-2)=-4 which is not 4 so f(-2)=4 is not true.
Answer:
She would have to do 219 haircuts in a month for the costs to be the same, which would be $428.
Step-by-step explanation:
To find this we take the costs of the first place.
$438
Next we can look at the costs of the second place using x as the number of haircuts she'd do.
2x
Now we can set the two equal to each other to find the number of cuts.
438 = 2x
219 = x
Answer:
Q 2 = B
Q3 = B
Q4 = C
Step-by-step explanation:
Q2 = B because if you do: cost per person ÷ Entrance cost
the proportinality will be correct
Q3 = B because 2 x 3.5 =7
4 x 3.5 = 7, so on and so forth.
Q4 = C because a pizza cost $15 with no topings. So if it has 2 toppings that will be 2x2 + 15 = $19. And they're asking you to find the cost of a pizza with two toppings
