Which are solutions to y=x-4? Choose all correct answers. (4,0), (3,-1), (6,3), (2,-4)

Answers

The correct answers are (4,0) and (3, -1)

The coordinates (4, 0) and (3, -1) represents the solution of the function f(x).

We have a function -

y = f(x) = x - 4

We have to identify the possible solutions of this function from the ones mentioned.

What do you understand by the Solution of a function -y = f(x)?

The solution of the function is the possible values of x (say a) for which f(a) equals to y.

According to the question -

y = f(x) = x - 4

Case 1 : P(4, 0)

0 = 4 - 4 = 0

P(4, 0) represents a solution

Case 2 : P(3, -1)

-1 = 3 - 4 = -1

P(3, -1) represents a solution

Case 3 : P(6, 3)

3 = 6 - 4 ≠ 2

P(6, 3) does not represents a solution

Case 4 : P(2, -4)

-4 = 2 - 4 ≠ -2

P(2, -4) does not represents a solution

Hence, the coordinates (4, 0) and (3, -1) represents the solution of the function f(x).

If the sales tax in Maple Town is 9.5%, how much would an ice cream of $4.25 cost with the tax added? Please explain.

Answers

To find the sales tax, you need to find 9.5% of 4.25

4.25*.095 = .40375

Now we need to add the sales tax to the price.

4.25 + .40375 = 4.65375
Because dollars one have 2 decimal points we should round this to 4.65

By how much peter is overweight he is 105 kg his aim is to lose 500 g per week if he manages this how many weeks will it be until he is 90 kg

Answers

Hello There!

105 - 90 = 15kg
500g = 1/2 kg
Peter is 15kg overweight.
15 x 2 = 30
It will take him 30 weeks for this.

Hope This Helps You!
Good Luck :)
First I would turn 500g into kg and then set up an equation like the following.

So lets convert 500g to kg. We do this by using a conversion factor.
 [tex]1g = 0.001kg = 1g:0.001kg = \frac{0.001kg}{1g}[/tex]


Now that we know this conversion factor lets set it up.

[tex]500g \times \frac{0.001kg}{1g} = 0.5kg = \frac{1}{2}kg [/tex]

Ok now we know Peter wants to lose 0.5 kg or [tex]\frac{1}{2}kg[/tex] a week.



Peter wants to lose 1/2 kg a week so we use x for weeks

Lost of weight per week 
[tex] \frac{1}{2}x [/tex]

Next, it tells us that Peter wants to be 90 kg. So he needs to lose 15kg. 
105 - 90 = 15kg

Now we need to find out how many weeks will it be untill he is 15kg. So, Lost of weight per week = 15kg

[tex] \frac{1}{2}x = 15 [/tex]
Now solve for x in [tex] \frac{1}{2}x = 15 [/tex]

[tex] \frac{1}{2}x = 15 [/tex]
[tex] 2 \times \frac{1}{2}x = 15 \times 2[/tex]
[tex] x = 30 [/tex]
So it will take 30 weeks at 1/2kg a week to lose 15kg

Convert to the given unit. 40 m to cm A. 0.4 cm B. 4 cm C. 400 cm D. 4000 cm

Answers

It's D because there are are 100 cm per m and so 40*100 = 4000

Final answer:

To convert 40 meters to centimeters, multiply by 100, since there are 100 centimeters in a meter. The result is 4000 centimeters.

Explanation:

To convert 40 meters to centimeters, we need to determine the correct conversion factor between meters and centimeters. Since we are going from a larger unit to a smaller unit, we will multiply.

There are 100 centimeters in one meter, so we use this as our conversion factor.

The conversion is as follows:

40 m × 100 cm/m = 4000 cm

Therefore, 40 meters is equal to 4000 centimeters.

Jim had 3,067.48 in his checking account.He wrote a check to pay for two airplane tickets. His account now has 1,845.24. How much did each ticket cost

Answers

Each ticket is 244.648 because you subtract the money you had in the account from how much you had left. Then you multiply 1,223.24 by 2 because it says that Jim bought 2 tickets and that should get you 244.648.

Answer:

Cost of one ticket=611.12

Step-by-step explanation:

In this question we have given

Amount in account= 3067.48

After purchesing 2 airplane tickets, amount in Jim's account=1845.24

Therefore,

Cost of two tickets=[tex]3067.48-1845.24[/tex]

Cost of two tickets=1222.24

Therefore,

Cost of one ticket=[tex]\frac{1222.24}{2}[/tex]

Cost of one ticket=611.12

A survey was conducted in local town on modes of transportation to work. The following circle graph shows the number of people who utilize each mode of transportation. If 320 people were surveyed, about how many of them would be expected to take a bus to work?

A. 42

B. 112

C. 130

D. 82

Answers

the numbers in ur circle add up to 120.....so the ones that took the bus were 42...

42/120 = x / 320...42 bus riders to 120 ppl = x bus riders to 320 ppl
cross multiply
(120)(x) = (42)(320)
120x = 13440
x = 13440/120
x = 112 <===

or u can also do it this way...
42/120 = 0.35 = 35%....so 35% took the bus
35% of 320 = 0.35(320) = 112 <=

2/3p-14=p+13
How do I solve this

Answers

Add 14 to both sides
2/3p=p+27

Subtract p from both sides
-1/3p= 27

Multiply both sides by -3
p= -81

Final answer: p=-81
So here you just want to move all the like terms to either sides.

You can do this by first adding 14 to both sides.

2/3p - 14 = p + 13

+ 14           +14

2/3p = p + 27

And then by subtracting p from both sides

-1/3p = 27

And then dividing both sides by -1/3

p = -81
