Answer:

Step-by-step explanation:

we are given 54x + 4.99x + 7.95

we can simplify like terms

58.99x + 7.95

It is D because in C it says "the actual delivery charge is $58.98" which is not true. It states in the question that it is "$7.95 for delivery", so it has to be D

What does the remainder theorem conclude given that f(x)/x+6 has a remainder of 14? Enter your answer by filling in the boxes.

musickatia [10]

Answer:

$f(-6)=14$

Step-by-step explanation:

According to the remainder theorem, if a function f(x) is divided by (x-a), then the remainder is defined by f(a).

It is given that $\dfrac{f(x)}{x+6}$ has a remainder of 14.

Here, the function f(x) is divided by (x+6). So, on comparing (x+6) and (x-a), we get

$a=-6$

So, by remainder theorem, remainder of $\dfrac{f(x)}{x+6}$ is f(-6).

Since the remainder is 14, therefore

$f(-6)=14$

Therefore, the answer for first blank is -6 and for second blank is 14, i.e., $f(-6)=14$ .

Faith is working two summer jobs, making $13 per hour lifeguarding and $12 per hour washing cars. Last week Faith worked a total

san4es73 [151]

Answer:

Step-by-step explanation:

Let's call lifeguarding L and car washing W. In order to write a system, we need to first separate the NUMBER of hours worked from the MONEY earned, because they are very different things.

If she works 10 hours, that is the number of hours worked between both jobs. Therefore, the equation for the NUMBER of hours worked is

L + W = 10.

If she earns $13 an hour lifeguarding, the expression for that is 13L; if she earns $12 an hour car washing, the expression for that is 12W. The MONEY she earned together by doing both those jobs is

13L + 12W = 124

There you go!

Hey guys, I know this is a lot so I am offering a lot of points. I was stumped on this paper, I just need a little help on how t

Llana [10]

So for number one, you would have to divide the number by the one being multiplied. I’ll do the first one and you can do the second one, comment if you need help.
(4)*_=-12 —> -12/4 = -3
Check : -3*4 = -12
The answer would be -3.
For the second one, multiply all the numbers first and find the actual answer.
(4)*(-7)*(-1) —> 4 * -7 = -28 —> -28 * -1 = 28
Then multiply their answers.
Evangelina : (-28)*(-1) = 28
Josh : (4)*(7) = 28

Now check who has the right answer and explain why.

For number three, use the letters and plug in the values that are being given to you.

e —> -e
-e * f = -15
-e * g = 6
f * g = -10

Now solve from there!

I really hope I helped, comment if you have any questions:)
