(x, y)->(x, y+5)

Answers

It’s the first answer choice... the translation was 5 units to the right (horizontal movement so it affects the x) and it’s to the right (which makes it a positive 5). It didn’t move up or down so the y stays the same

The zeros of a quadratic function are 4 and 8. What is the axis of symmetry of the function?

PLS HELP AND IF YOU COULD SHOW UR WORK IT WOULD HELP A LOT <33

Answers

So if you want to have a factored form...

If the zeroes are +4 and +8, you would write
(X-4) (x-8)
Then you would multiply it out to get to quadratic form...

So, (x-4)*(x-8)
X^2 - 12x + 32

Then you would plug it into the formula for axis of symmetry...
X= -b/2a

X=12/2 = 6

Henry spent 1 hour 30 minutes less than Joey reading last week. Joey spent 50 minutes less than Pete. Pete spent 3 hours reading. How long did Henry spend reading?

Answers

Answer: Henry read for a total of 40 minutes

Step-by-step explanation: 3:00 - 0:50 is 2:10 then 2:10 - 1:30= 40 minutes

Answer:

Henry spent 40 minutes reading

Step-by-step explanation:

Pete spent 3 hours of reading = 180 minutes

Joey spent 50 minutes less than Pete 180 - 50 = 130

180 - 50 = 130

Joey spent 2 hours and 10 minutes

But Henry spent 1 hour and 30 minutes less than Joey which is 90 minutes

s=t+5
4s+2t=110
pls help me

Answers

Answer:

t = 40/3 (exact)

t = 13.3 (decimal)

t = 13 1/3 (mixed number)

Step-by-step explanation:

Simplify 4 (t + 5) + 2 (t + 5).

6t + 30 = 110

Move all terms not containing t to the right side of the equation.

6t = 80

Divide each term by 6 and simplify.

t = 40/3

The result can be shown in multiple forms.

t = 40/3 (exact)

t = 13.3 (decimal)

t = 13 1/3 (mixed number)

Answer:

s=20

Step-by-step explanation:

First, plug in s to the equation.

4(t+5) + 2t =110

Then, distribute. That means multiply 4 to the variable and number inside the parentheses.

4t + 20 +2t = 110

Now, add like terms. The two numbers, 4t and 2t can be combined because they have the same variable.

6t + 20 = 110

Subtract 20 from 110 to isolate the variable.

6t = 90

Now, divide 90 by 6 to further isolate the variable.

t = 15

Now we have to find s. To find s, plug t = 15 into the equation.

s = 15 + 5

Lastly, add the two numbers to find s.

s = 20

Check your work! Plug in t = 15 and s = 20 to the equation.

4(20) + 2(15) = 110

Multiply.

80 + 30 = 110

110 = 110

This means your answers are correct! Hope this helped! :)

Like terms are numbers that are... well alike. For example 2x and 4x are like terms because they the x in common.
