Which relation is a function?
a.
{(5,3), (2,8), (-5, -1),(4,7), (2, 1)}
b. {(5,3), (2,8), (-5,-1), (4,7), (-2, 1)}
{(5,3), (2,8), (-5, -1), (4,7), (5,7)}
d. {(-5,3), (2,8), (-5, -1), (4,7), (
2, 2)}
Answer: b
Step-by-step explanation:
You can determine which is a function by looking at the x values. If an x value repeats, it is not a function. In A, the x variable 2 repeats so it is not a function. In C, the x variable 5 repeats. In D, the x variable -5 repeats. The only answer choice where none of the x values are the same is B, so the answer is B. Hope this helps!
Which equations would be related to x - 7 = 38
Answer:
-7+x=38,
Step-by-step explanation:
what is the volume
Answer:
The volume is 227.5
Step-by-step explanation:
The volume for a triangular prism, such as this is, (lxwxh)/2. Because in all shapes volume equals the area multiplied by the height or depth. And an area of a triangle is l or base multiplied by the altitude or w, divided by 2. So the area would be 5x7/2, 35/2, 17.5. And the volume would be 17.5x13, 227.5
Find three consecutive integers whose sum is 57????
Answer:18 19 20
Step-by-step explanation:"Consecutive" means that the integers will follow each other in value, for example: 1, 2, 3 or 4, 5, 6. Also, no decimals are needed here because "integers" are whole, counting numbers. Here is the set up: Let x= the first integer Then X+1= 2nd consecutive integer and x+2= 3rd .
Suppose that x=1 x+1= 1+1=2 and x+2=1+2=3 However, you need specific consecutive numbers whose sum is 57. Remember that sum means to add:
x+ (x+1) + (x+2) = 57 Addition of all 3 consecutive numbers Now solve for x
and substitute into each part to come up with the three integers:
3x + 3= 57 3x=54 x=54/3 = 18 x=18, x+1= 18+1=19 x+2=18+2=20
Check your answer: 18+19+20=57 57=57 Check

At noon, a tank contained 8 in. of water. After several hours, it contained 2 in. of water. What is the
percent decrease of water in the tank?
Answer:
75%
Step-by-step explanation:
To find the percent decrease, use the percent change formula:
(difference / original) x 100
8 - 2 = 6, so the difference is 6.
Plug in the difference and original:
(6 / 8) x 100
= 75
So, the percent decrease is 75%
Help please ? What’s the inequality?
9514 1404 393
Answer:
-1 < x < 5
Step-by-step explanation:
The open circle at -1 and the shading to its right tells you ...
-1 < x
The open circle at 5 and the shading to its left tells you ...
x < 5
Both of these are true together, so the compound inequality representing that is ...
-1 < x < 5
_____
Additional comments
If the circle were filled, the relation would include the "or equal to" case: ≤.
I like to use the "left-pointing" relation symbols (<, ≤) because they put the numbers and variables in the same relationship they are on the number line. That is, -1 is on the left end of the shaded segment; the shading (variable value) is in the middle, and 5 is on the right end--the same as ...
-1 < x < 5

Find the angle from your calculator using tan-1
:)
Answer:
1 = 88 2 = 42 3 = 113
Step-by-step explanation:
2 is 42 because it is the opposite angle and then you subtract 42 and 50 from 180 to get 88 for #1 and you subtract 42 and 25 from 180 to get 113 for #3.
2. Determine the scale factor of a drawing if the scale is 1 inch = 4 feet.
Answer: Therefore the scale factor is 48 times.
Step-by-step explanation: Since the drawing is in inches, the scale will be 1/4
the scale is 1 inch to 4 FEET.
Convert feet to inches
1 inch to 48 inches
So the ratio is 1:48
Roberto wants to display his 18 sports cards in an album. Some pages hold 2 cards and others hold 3 cards. How many different ways can Robert display his figures?
Answer:
3 is an odd number, so we need an even number of sets of 3 cards because 18 is an even number.
So we need 0, 2, 4 or 6 sets of three.
0 2-card + 6 3-card, 3 2-card+4 3-card, 6 2-card+2 3-card, 9 2-card+0 3-card. There are only 4 combinations:
(2-card, 3-card)=(0,6), (3,4), (6,2), (9,0).

Jodi owes $38,000 in students loans for college. The interest rate is 7.25% and the loan will be paid off over 10 years. How much will Jodi pay TOTAL?
Answer:
Jodi will have to pay $38,000 in principal plus $27,550 in interest for a total of $65,550.00.
Step-by-step explanation:
Solution:
P = $38,000, R = 7.25% and T = 10
I = P*R*T
I = (38000)*(.0725)*(10) = $27,550.00
Answer: Jodi will have to pay $38,000 in principal plus $27,550 in interest for a total of $65,550.00.
Answer: Jodi will pay $65,550.00 in total.
Steps: 7.25% of $38,000 is $2,755.00
Multiply 2,755.00 times 10: 2,755 × 10 = 27,550
$38,000.00 + $27,550.00 = $65,550.00

ΔABC is dilated using a scale factor of 12 to produce ΔA'B'C'. Select all of the statements that apply to the transformation.
Answer:
Options (3) and (6)
Step-by-step explanation:
ΔABC is a dilated using a scale factor of [tex]\frac{1}{2}[/tex] to produce image triangle ΔA'B'C'.
Since, dilation is a rigid transformation,
Angles of both the triangles will be unchanged or congruent.
m∠A = m∠A' and m∠B = m∠B'
Since, sides of ΔA'B'C' = [tex]\frac{1}{2}[/tex] of the sides of ΔABC
Area of ΔA'B'C' = [tex]\frac{1}{2}(\text{Area of triangle ABC})[/tex]
Area of ΔABC > Area of ΔA'B'C'
Since, angles of ΔABC and ΔA'B'C' are congruent, both the triangles will be similar.
ΔABC ~ ΔA'B'C'
Therefore, Option (3) and Option (6) are the correct options.
Answer: The Third option and the sixth option.
