Describe a math tool you could use to determine if a relation is a function. Explain how you would use it. Select all that apply.
Multiple select question
A)
I could use a mapping diagram. If more than one arrow points from an input value to the output values, I know it is not a function.
B)
I could use a straight object like a pencil. If the pencil intersects a graph at more than one point when it is held vertically, I know it is not a function.
C)
I could use a table. If I see that there is more than one output for an input, then the relation is a function.
D)
I could use a straight object like a pencil. If the pencil intersects a graph at more than one point when it is held horizontally, I know it is not a function.
E)
I could use a mapping diagram. If more than one arrow points from an output value to the input values, I know it is not a function.
Answer:
C, Identify the input values. Identify the output values. If each input value leads to only one output value, classify the relationship as a function. If any input value leads to two or more outputs, do not classify the relationship as a function.

4. Eric has 54 yards of fencing to use for a flowerbed. Some possible measurements are
shown below. For which flowerbeds does Eric have enough fencing? Color in all the
possible answers.
A.
length = 30 yards
area = 300 square yards
B.
length = 20 yards
width = 5 yards
C.
width = 12 yards
perimeter = 48 yards
D.
length = 26 yards
width = 22 yards
E.
length = 16 yards
width = 14 yards
F.
width = 9 yards
area = 162 square yard
Answer:
Step-by-step explanation:
1
perimeter = 9 · 4 = 36 m
area = 9² = 81 m²
2
perimeter = (10+14) · 2 = 24 · 2 = 48 in
area = 10 · 14 = 140 in²
3
width = 63 : 7 = 9 km
9 · 2 = 18 km
7 · 2 = 14 km
area = 18 · 14 = 252 km²
4
A 300 : 30 = 10
(10 + 30) · 2 = 40 · 2 = 80 (no)
B
(20 + 5) ·2 = 25 · 2 = 50 yd (ok)
C
perimeter is 48 yd (ok)
D
(22 +26) · 2 = 48 · 2 = 96 yd (no)
E
(16 + 14) · 2 = 30 · 2 = 60 yd (no)
F
length = 162 : 9 = 18 yd
(18 +9) · 2 = 27 · 2 = 54 yd (ok)
Answer:
1
perimeter = 9 · 4 = 36 m
area = 9² = 81 m²
2
perimeter = (10+14) · 2 = 24 · 2 = 48 in
area = 10 · 14 = 140 in²
3
width = 63 : 7 = 9 km
9 · 2 = 18 km
7 · 2 = 14 km
area = 18 · 14 = 252 km²
4
A 300 : 30 = 10
(10 + 30) · 2 = 40 · 2 = 80 (no)
B
(20 + 5) ·2 = 25 · 2 = 50 yd (ok)
C
perimeter is 48 yd (ok)
D
(22 +26) · 2 = 48 · 2 = 96 yd (no)
E
(16 + 14) · 2 = 30 · 2 = 60 yd (no)
F
length = 162 : 9 = 18 yd
(18 +9) · 2 = 27 · 2 = 54 yd (ok)

Carmela mixes 3/4 kilograms of walnuts, 1/2 kilograms of almonds,and 1/4 kilograms of pecans together. She divides the mixed nuts into 3/10 kilogram bags. How many bags of mixed nuts does she have. PLEASE HELP DUE TOMORROW.
Answer:
5 bags of mixed nuts.
Step-by-step explanation:
First, we add the amount of nuts together.
3/4 + 1/4 = 1
1 + 1/2 = 1 1/2
1 1/2 = 3/2 as an improper fraction.
Then we divide 3/2 by 3/10
To divide fractions, use "Keep, Switch, Flip"
Keep the first number, switch the sign, and flip the second fraction.
3/2 * 10/3 = 30/6 = 5.

2(m + 2) =22 Describe what it means to distribute the 2 to each term inside the parenthesis
Answer:
Step-by-step explanation:[tex]\frac{2(m+2)}{2}[/tex]
step 1
2(m+2)=22=2x11
step 2
:[tex]\frac{2(m+2)}{2}=\frac{2*11}{2}[/tex]
step 3
(m+2)=11
step 4
m=11-2=9
Answer: (see below)
Step-by-step explanation:
2 distributed to each term inside 2(m + 2) looks like this:
2m + 4
first multiply 2xm, then 2x2
Now you have an expression where you can solve for m:
2m + 4 = 22
2m = 22 - 4 = 18
m = 18/2 = 9
