Answer:

x = - 5

Step-by-step explanation:

Remember that f(x) is the same value as y. So if f(x) = 1 then y = 1

There is only 1 point that has a y value of 1 and it is on the far left. The value you want is - 5

The answer is x = - 5 when f(x) = 1

Molly bought 4.25 pounds of fish for $10.20. What is her unit rate (cost per pound)?

Answers

Answer:

$2.40 per pound

Step-by-step explanation:

Take the cost and divide by the pounds

$10.20/ 4.25 pounds

$2.40 per pound

Answer: The answer is 2.4

To find out the cost per pound, you just have to divide. For example, in this problem, you would divide 10.20 by 4.25 to see how much money it is for one pound of fish

A bacteriologist estimates that there are 5.2×10^4 bacteria growing in each of 20 petri dishes. About how many bacteria in total are growing in the petri dishes? Express your answer in scientific notation

Answers

Answer:

1X10^6

or

1.04x10^6

Step-by-step explanation:

You start by multiplying 5.2x10^4 by 20 because there are 20 petri dishes with this amount growing, and you get 1,040,000. Now we need to convert it to scientific notation. We know that 1,000,000 is 10^6, so we would move the decimal to the left 6 places and get 1.04x10^6. This is in scientific notation, but we need to keep in mind significant figures (sig figs), so your final answer would be 1x10^6, if that is not what your instructor is looking for, try 1.04x10^6.

What the answer to PTR?

Answers

Answer:

∠ PTR = 140°

Step-by-step explanation:

∠ PTQ and ∠ RTS are vertical and congruent, thus

2x + 16 = x + 28 ( subtract x from both sides )

x + 16 = 28 ( subtract 16 from both sides

x = 12

Thus ∠PTQ = x + 28 = 12 + 28 = 40°

∠ PTQ and ∠ PTR are adjacent and supplementary, thus

∠ PTR = 180° - 40° = 140°

Answers

Answer:

John's ball hit the court first

Step-by-step explanation:

to solve for who hit the court first we have to look for when x was 0

John's ball hit the court in 1 second

now to look for the other guy we substitute 0 to the equation

0 = (-16t - 2) (t - 2)

we cannot substitute 0 to t because its looking for when it hit the court. x is 0 because it hits the ground

soo i guess we distribute ?

or actually we equate both to 0 i think

-16t - 2 = 0   t - 2 = 0

-16t =  2.      t = 2

t = 2/-16

t = 1/-8   t = 2

theres two answers but 1/-8 is wrong because theres no such thing as the ball going underground (LOL) so his ball hit the court two seconds later

John's ball hit the court first i think

im not sure how to do the rest, but i do know how to do the first. Sorry but hope this helps you a little!
