What is the solution to the equation -10.3+y=5.2

Answers

Answer 1

Answer:

Step-by-step explanation:

I think it would be something like this, maybe

-10.3+y=5.2

-103/10+y=52/10

(-103)+10y/10=2*2*13/2*5

y=31/2

which is 15.5

What is 1/5 + 2/3 help

Answers

You need to simplify so one-fifth would be 3/15 and 2/3 would be 10/15 so you need to add that together and it would be 13/15

13/15 is the right answer. First you had to add by the fractions. And it gave us, $(3)/(15)+ (10)/(15)$ . Since the denominator are equal, and then combine by the fraction. And it gave us, $(3+10)/(15)$ . Finally, add the numbers and it gave us the answer is 13/15 is the right answer. Hope this helps!

Answer:x=4

Isolate the variable by dividing each side by factors that don't contain the variable.

The answer is x=4 I hope it correct

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.
