Terrell's plant grew 2 5/8 inches in one month, and it is 7 1/4 inches tall. Write and solve an equation to find the height of the plant at the start of the month. Show that your answer is reasonable. Thanks

Answer 1
Answer:

Answer:

4(5)/(8) inches

Step-by-step explanation:

Let initial length of the plant was "x" inches.

Plant grew 2(5)/(8) inches or (21)/(8) inches per month.

So after one month height of the plant = (x+21)/(8) inches

Height of the plant after one month = 7(1)/(4) or (29)/(4) inches

So expression will be

(x+21)/(8) =  (29)/(4)

We further solve it    x =  (29)/(4) -  (21)/(8)

                                    =  (58-21)/(8)

                                   =  (37)/(8)

                           or x  =  4(5)/(8) inches

therefore, initial of the plant was 4(5)/(8) inches height.

7e−4=31 solve for e.

Answers

solve your equation step-by-step.

7x−4=31

Add 4 to both sides.

7x−4+4=31+4

7x=35

Divide both sides by 7.

7x/7 = 35/7

x=5
7e-4=31 add 4 to both sides = 7e=35 then divide 7 on both sides then you get the answer of e=5

Round 81.139 to the nearest tenth

Answers

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).


If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).

81.139 ≈ 81.1
the first place after the decimal place is the tenth's place, then next is the hundreth's and so on

when rounding, if the number is 5 or more then round up , if less than 5, round down
exg\
.5 runded up=1
.4 rounded would be 0


so 81.139
disregard the 9
81.13
3 is less than 5
81.10

The current value of a baseball card is 60 times its original value v(in dollars). The baseball card is worth $15. Write and solve an equation to find the original value of the baseball card.

Answers

60v = $15

60v/60 = $15/60

v = 0.25

The original value of the baseball card is $0.25

The table below shows the outputs y for different inputs x:Input
(x) 1 1 3 3
Output
(y) 4 2 12 6


Part A: Does the table represent y as a function of x? Justify your answer. (5 points)

Part B: The total cost f(x), in dollars, for renting a paddleboat for x hours is shown below:

f(x) = 20 + 10x

What is the value of f(120), and what does f(120) represent? (5 points

Answers

Answer with explanation:

Part A:

  • A relation is said to be a function where each input has only a single output.

We usually take the input variable as 'x' and the output variable as 'y'.

In the given table, we can see that 1 is the input value corresponding to 4 and 2 both.

i.e.  one input value corresponds to two different output values that contradicts the definition of the function.

Thus  the given table doesn't represent any function.

Part B: Given : The total cost f(x), in dollars, for renting a paddle-boat for x hours is shown below:

f(x) = 20 + 10x

At x= 120 ,  f(120) = 20 + 10(120)=20+1200=1220

It represents that the total cost  for renting a paddle-boat for 120 hours is $1220.
Part A)
The table doesn't represent y as a function of x.
Why? One reason is that 1 or 3 is the first element in more than one ordered pair.
 Part B)
f(x) = 10x + 20
f(120)= 10*120 + 20 = 1200 + 20 = 1220 
f(120) represents cost of boating for 120 hours.
