Answer:

{324, 0, -6, 54}

Step-by-step explanation:

Given that F(x) = 3x² − 3 x − 6 If the domain of a the function f(x) is { -10, -1, 1, 5 }.

To get the range, we will find f(x) for all the domains

at x = -10

f(-10) = 3(-10)²-3(-10) - 6

f(-10) = 3(100)-3(-10) - 6

f(-10) = 300+30-6

f(-10) = 330-6

f(-10) = 324

at x = -1

f(-1) = 3(-1)²-3(-1) - 6

f(-1) = 3(1)-3(-1) - 6

f(-1) = 3+3-6

f(-1) = 6-6

f(-1) = 0

at x = 1

f(1) = 3(1)²-3(1) - 6

f(1) = 3(1)-3(1) - 6

f(1) = 3-3-6

f(1) = 0-6

f(1) = -6

at x = 5

f(5) = 3(5)²-3(5) - 6

f(5) = 3(25)-3(5) - 6

f(5) = 75-15-6

f(5) = 60-6

f(5) = 54

Hence the range of the relation are {324, 0, -6, 54}

=

16

We multiply it by

because that's our total and by

then that would mean we got every question right.

Given that :

Number of adults = 24

Number of children = 64

Number of people per van = 8

Number of vans required :

Total number / number per van

(64 + 24). / 8

= 88 / 8

Answer: Not sure if the second one is times or just the variable x, i assume its the variable x. Answer:

x=5

Step-by-step explanation:

Let's solve your equation step-by-step.

3x−12=−4x+23

Step 1: Add 4x to both sides.

3x−12+4x=−4x+23+4x

7x−12=23

Step 2: Add 12 to both sides.

7x−12+12=23+12

7x=35

Step 3: Divide both sides by 7.

Step-by-step explanation:

[tex]-4(-3x-8)-34[/tex] (Distribute the -4)

[tex]12x+32-34[/tex] (Subtract)

[tex]12x-2[/tex]

And if you want to find x.

[tex]12x-2=0[/tex] (Add 2 on both sides)

[tex]12x=2[/tex] (Divide by 12 on both sides)

Answers and Step-by-step explanations:

9:  (4/6) (-5/8)  

This is just multiplication of fractions, so all you need to do is multiply both numerators by eachother and both denominators by eachother.  Assuming that only the 5 is negative, (this is just an assumption since it's not clear which one is, or you can do the 8,)  You get -20/48, since 4 x (-5) = -20, and 6 x 8 = 48.  Simplify and you get -5/12.  

10:  (3/4) (-1/5)  

Multiply the numerators, (3 and -1), and the denominators, (4 and 5,) to get -3/20.  This is the lowest it can be simplified to, so therefore your answer is -3/20.  

11.  (-1/8) (-6/7)  

Multiply -1 and -6 to get 6, (since two negatives make a positive.)  Multiply the denominators, (8 and 7,) to get 56.  This maks 6/56, which simplifies to 3/28.  

12.  (-4/9) (1/5)  

Multiply the numerators, (-4 and 1,) to get -4.  Multiply the denominators (9 and 5,) to get 45.  Your answer is -4/45.    

I'm really sorry if I'm wrong for anything, hope this helps!  :)

Answer:tttaergfzgsfbvzfsbzfzbfs

The amount of interest that you earn after a year will be $7.875.

A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.

We know that the compound interest is given as

[tex]\rm A = P \left (1 + \dfrac{r}{n} \right ) ^{nt}[/tex]

Where A is the amount, P is the initial amount, r is the rate of interest, and t is the number of years.

You have $350 in your savings account, which has a 2.25% interest rate.

Then the amount of interest that you earn after a year will be given as,

I = A - P

I = $350(1 + 0.0225) - $350

I = $350 (1.0225) - $350

I = $357.875 - $350

I = $7.875

The amount of interest that you earn after a year will be $7.875.

Answer:

Step-by-step explanation:

A possible error is (c) C.12×4 does not equal 13.

From the question, we have the following parameters that can be used in our computation:

Rate = 1/3 miles in 4 minutes

When converted to unit rate, we have

Rate = 1/3 miles/4 minutes

Evaluate the quotient

So, we have

Rate = 1/12 miles per minute

This means that a possible error is (c) C.12×4 does not equal 13.
