Please help! I’m in 6th grade and I can’t remember how to do this

Answers

Answer 1

Answer:

2a + 4 + 7b

Step-by-step explanation:

ohh so to do this umm if you want it to be easier you can put a different symbols under the ones with the same variable. like a dot under 4a and - 2a, a square under .....

but if you want to do it without that, all you have to do is add them like numbers

you can also move them closer to each other. for example:

4a - 2a + 8 - 4 + 7b

4 - 2 is 2 so you just have to write 2a

2a + 8 - 4 + 7b

simplify

2a + 4 + 7b

since there are no other numbers with the variable b the equation above is the answer

help????????????????

Answers

x = 0 is a vertical line.

If a point is reflected across a vertical line, x-value becomes the distance from the reflection line and the sign changes most likely.

Thus if (-4,3) is reflected across a vertical line, its sign change and it becomes (4,3)

The answer is (-3,4) because mirrored give you -3 and then mirror the -4 and you get just 4

Answer:

No.

Step-by-step explanation:

In a function, two points CANNOT be directly above each other. In this case, (1,3) and (1,-2) are above each other.

For this question I would say No. The reason why is because you can tell in the picture of the points can’t be like above one another.

Make sure to enter your answer as an ordered pair. (x,y)

Answers

Answer:

(12, -23)

Step-by-step explanation:

Equate the equations:

y = y

⇒ -3x + 13 = -2x + 1

Add 3x to both sides:

⇒ -3x + 13 + 3x = -2x + 1 + 3x

⇒ 13 = 1 + x

Subtract 1 from both sides:

⇒ x = 12

Substitute x=12 into one of the equations to find y:

⇒ -2(12) + 1 = -23

Therefore, the ordered pair is (12, -23)

(X,y)=(12,-23)
All you had to do was solve for x first and once you found your answer plug it in for x and then solve for y

A swimming pool holds 250,000 gallons of water and is being drained at 200 gallons per minute. How many gallons remain in the pool after 5 minutes than after 20 minutes?

Answers

Answer:

After 5 minutes, the pool will hold 249,00 gallons of water.

After 20 minutes, the pool will hold 246,000 gallons of water.

After 5 minutes the pool will have 249,000 gallons since 5x200=1000 and 250,000-1000=249,000.
After 20 minutes it will be at 246,000 gallons since 20x200=4000 and 250,000-4000= 246,000.

Youssef has $40 in his piggy bank and he spends $2 a day on a soft pretzel at lunch. Tiernan is selling his lunch each day at school to save up for an electric skateboard. After 3 days, he has a total of $22 and after 6 days he has a total of $34. In how many days will the two have the same amount of money?

Answers

Answer: 5 days

Explanation:
Tiernan
10 + 4d
10 + 4(5) = 30

Youssef
40 - 2d
40-2(3) = 34
40-2(4)= 32
40-2(5) = 30

They two shall have the same amount of $30 after 5 days

[Consider "d" is number of days, "y" is total amount]

For Youssef:

Starting amount = $40Spending amount = $2

1) Equation created: y = 40 - 2d ____ eq(1)

For Tiernan:

3 days = $226 days = $34

Unit rate: (change in amount)/(change in day) = (34 -22)/(6-3) = $4

2) Equation created:

y - 22 = 4(d - 3)y = 4d - 12 + 22y = 4d + 10 ____eq(2)

For them to have same amount, solve simultaneously:

4d + 10 = 40 - 2d4d + 2d = 40 - 106d = 30d = 30/6 = 5 days

Amount after 5 days: 4(5) + 10 = $30
