Answer:

the last one is the answer I thin

Answer:

D

Step-by-step explanation:

Hey There!

Remember in order for the relation to be a function none of the x values can repeat

For the first one the x value 0 repeats therefore it is not a function

for the second one the x value -7 repeats thus meaning that its not a function

for the third one the x value 6 repeats hence, it is not a function

for the last one each input has a different output therefore it is a function

Answer:

y=5.4

Step-by-step explanation:

So first we cross multiple.

2*112=35*(y+1)

224=35y+35

-35 on both sides

189=35y

÷35 on both sides

5.4=y

Answer:

1

Step-by-step explanation:

Note that:

a = -4

b = 3

Plug in the corresponding numbers to the corresponding variables:

2a + 3b

2(-4) + 3(3)

Remember to follow PEMDAS. First multiply, then add:

2 * -4 = -8

3 * 3 = 9

-8 + 9 = 1

1 is your answer.

Answer:

De acuerdo a la información proporcionada, dado que se van a repartir 5 barritas entre 8 niños, se tiene que dividir las barritas entre el número de niños y a partir de aquí, se construye la fracción 5/8. Esto lo que indica es que cada barrita se divide en ocho pedazos y cada niño recibiría 1/8 de cada barrita y para las 5 barritas sería:

1/8*5=5/8

Answer: 30 cubic units

Step-by-step explanation:

Since the base has a volume of 2x3 or 6 and he plans on making the height 5 we must mutliply the base by height to get the new voulme so 6*5=30

Answer:

M= ([-1],[1/2])

The number in the green box is -1

Step-by-step explanation:

M= ([x1+x2/2], [y1+y2/2])

M= ([2+(-4)/2], [5+1/2])

M= ([-2/2, 6/2])

M= ([-1, 3])

Answer:

9

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

Based on what is stated in the question :

Expressing the worded equation Mathematically,

(5x - 7) / 2 = y

If y = 28

(5x - 7) / 2 = 28

Cross multiply

5x - 7 = 28 * 2

5x - 7 = 56

5x = 56 + 7

5x = 63

x = 63 / 5

x = 12.6

Hence, x ≠ 9

Answer:

I think it's c

Step-by-step explanation:

Answer:

You are going to take the shape and flip if across the x Axis, reversing it essentially. then you will move it up 4, so of it is a square with one corner at (2,3) it will go to (5, 7) and all the other point will move together if I remember right. I last did this 3 years ago, I hope I help, next time show the whole graph with the number and I would have put a visual to show you the answer. Good luck

Answer:

-48 ; - 16

Step-by-step explanation:

Given the expression :

X /4 = - 12

Multiply both sides by 4

X/4 * 4 = - 12 * 4

X = - 48

For the second :

X/2 = - 8

Multiply both sides by 2

X/2 * 2 = - 8 * 2

X = - 16

Answer:

9.75

Step-by-step explanation:

Answer: 58.33π units ³

Step-by-step explanation:

The volume of a cylinder = πr²h

The volume of a cone = 1/3πr²h

Since we have been told that the volume of this cylinder is 175pi cubic units and that the cone has the same base area and the same height, then the volume of the cone will be the volume of the cylinder divided by 3. This will be:

= 175π / 3

= 175/3π

= 58.33π units ³

The volume of the cone is 58.33π units ³

Answer:

183

Step-by-step explanation:

When multiplied by pi, it rounds out to 183.

Complete question :

Laura and Martin obtain a 30-year, $180,000 conventional mortgage at 10.0% on a house selling for $210,000. Their monthly mortgage payment, including principal and interest, is $1566.00. Determine the total amount they will pay for their house. How much of the cost will be interest? How much of the first payment on the mortgage is applied to the principal?

Answer:

$563760 ; $383760 ; $66

Step-by-step explanation:

Given that:

Monthly mortgage payment = $1566

Period = 30 years

Number of months in period = (30 * 12) = 360

Principal = $180,000

1.)

Total amount paid :

Monthly payment * period

$1566 * 360 = $563760

2.)

Total amount paid = Principal + Interest

Interest = Total amount paid - principal

Interest = $563760 - $180000

Interest = $383760

3)

First payment = 1566

Interest rate = 10% per annum = 0.1 / 12 = 0.0083333

monthly interest: 180,000 * 0.0083333 = 1500

Principal = 1566 - 1500 = $66

Answer:

110888

Step-by-step explanation:

v=surface area *radius

v=528*21=110888cm3

Answer: the height is 4

I think you make mistakes

but that is the height

Step-by-step explanation:

h =height=?cm

R=radius=21cm

A =surface area 528cm

Answer:

x=28

Step-by-step explanation:

I am assuming the mean is arithmetic mean. So we first add up the numbers:

6+10+12+18+16+x

=22+10+30+x

=22+40+x

=62+x

Then since there's 6 numbers in total, we have an equation:

[tex]\frac{62+x}{6}=15\\62+x=90\\x=28[/tex]

The answer is 28!

Have a nice day! :)
