Answer:
Matt has 7/12 of the jar of marbles left.
Step-by-step explanation:
In order to find this, simply subtract the 3/4 from the full jar (1) and then add 1/3. They will need common denominators to complete this operation.
1 - 3/4 + 1/3 = Amount
12/12 - 9/12 + 4/12 = Amount
7/12 = Amount
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.
