Answer:

  $750

Step-by-step explanation:

The 20% discount multiplies the price by (1 - 20%) = 0.80.

The 15% discount multiplies the price by (1 - 15%) = 0.85.

After applying the discounts to the initial price P, we have ...

  P(0.80)(0.85) = $510

  P = $510/(0.80·0.85) = $750

The price before discounts was $750.

Answer: Each shelf is 2ft

Step-by-step explanation:

16 = (2 x 4) + 4s

16 = 8 + 4s

8 = 4s (subtract 8 from both sides)

8/4 = 4s/4 (divide both sides by 4)

2 = s

Answer:

6/8

Step-by-step explanation:

Answer:

As the x=-2 does not satisfy the inequality.

Therefore, the solution is False!

Step-by-step explanation:

Given the expression

[tex]x-10x+1<\:20+\:5x\:[/tex]

substituting the value x = -2

[tex]\left(-2\right)-10\left(-2\right)+1<20+5\left(-2\right)[/tex]

[tex]-2+20+1 < 20-10[/tex]

[tex]19 < 10[/tex]

As the x=-2 does not satisfy the inequality.

Therefore, the solution is False!

Answer:

The constant rate is 4

Step-by-step explanation:

40 ÷ 10 = 4

80 ÷ 20 = 4

120 ÷ 30 = 4

160 ÷ 40 = 4

They all equal 4 so that is the constant rate.

Answer:

if I'm correct, it should be 6.125. I'm sorry if I'm wrong,

Step-by-step explanation:

take 3.5 and divide it by 4, which gives you the amount for 1 lemon. times that by 7, and you get 6.125

Answer:

8 lemons

Step-by-step explanation:

7- 3.5= 3.5

Therefore we multiple 3.5 by 2.

We always do the same on the other side.

4 times 2 equals 8

7 liters of water: 8 lemons

Answer:

its gonna be whatever the y value is when x is 22

Step-by-step explanation:

Answer:

The answer is: 37

Step-by-step explanation:

The reason its this answer because first thing you have to do is the order operations Please Excuse My Dear Aunt Sally, since there is no parenthesis, or exponents we cross those out. Since, there is multiply we put in -14 where is x.

-3x-5=-3(-14)=5

Next, we multiply -3 and -14 and we get:

42, there reason its not a negative because two negatives equal to a positive.

There is Division or Addition, those are out. The only thing that is left Subtraction... So we are going to subtract 42-5 which equals;

Answer:

10.80

Step-by-step explanation:

12% of $9 dollars is $1.08 rounded is 1.080

btw if this was a real job id quit even though im in 6th

The minimum number of hours you will need to work in order to save enough money for your tuition alone is 125 hours.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

You are going to attend night classes for 4 months. You have to earn an additional $987 for tuition within this time.

You decide to take a second job that pays $9 dollars an hour.

Taxes are 12% of your earnings, and you are able to save the rest.

Let x be the minimum number of hours you will need to work in order to save enough money for your tuition alone.

From the data given, we can frame a linear equation in one variable.

987 = 9x - 12% of 9x

987 = 9x - (0.12)(9)x

987 = 9x - 1.08x

7.92x = 987

x = 987/7.92

x = 124.62 ≈ 125 hours

Thus, the minimum number of hours you will need to work in order to save enough money for your tuition alone is 125 hours.

Answer:

6 movies = 1st plan

7 movies = 1st plan

8 movies = Either is fine. (They're the same price)

9 movies = 2nd plan

10 movies = 2nd plan

Step-by-step explanation:

6 movies (1st plan) = 20 + 5 × 6

                               = 50 (less than 60 so it is cheaper)

7 movies (1st plan) = 20 + 5 × 7

                               = 55 (less than 60 so it is cheaper)

8 movies (1st plan) = 20 + 5 × 8

                               = 60 (same as 2nd plan so either is fine)

9 movies (1st plan) = 20 + 5 × 9

                               = 65 (more than 60 so 2nd plan is better)

10 movies (1st plan) = 20 + 5 × 10

                               = 70 (more than 60 so 2nd plan is better)

Answer:

D

Step-by-step explanation:

189 boys is 54%

x is 46%(100-54)

Cross multiply:

189*46%=54%*x

86.94=0.54x

x=161

189 boys 161 girls

350 altogether

So D

Answer:

x=2

Step-by-step explanation:

move x to the 3x side and move 5 to 9 side.

you get 2x=4

then you divide 2 from both sides and get 2

Answer:

x=2

Step-by-step explanation:

•Original Expression;

3x+5=x+9

•Group like terms;

3x-x=9-5

•Simplify

3x-x

=2x

Then

9-5

=4

Which is going to be;

2x=4

•Divide both sides by 2 to find x

4 can be divided by 2 two times so;

x=2

Answer:

D. x = 3

Step-by-step explanation:

We would like to find out for what value of x does f(x) = g(x). This is essentially the same as asking us to find the x-value for which f(x) = k, where k is some number, and g(x) = k, as well.

Looking at the two tables provided, we notice that when x = 3, both f(x) and g(x) equal -2. So, the answer is D.

Answer:

2. Eunju is right

3. [tex]x^2+5x+6[/tex] is a factor of [tex]x^4+5x^3+2x^2-20x-24[/tex].

Step-by-step explanation:

Polynomial Remainder Theorem

The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-a) is equal to f(a).

As a consequence, if a polynomial is divisible by x-a, f(a)=0.

Part 1:

Let's make:

[tex]f(x)=(x+b)^3+(x+c)^2-(b-c)[/tex]

To find out if x+b is a factor of f(x), we find f(-b):

[tex]f(-b)=(-b+b)^3+(-b+c)^2-(b-c)[/tex]

Operating:

[tex]f(-b)=(-b+c)^2-(b-c)[/tex]

The value of f(-b) is not zero. This means Eunju is right, x+b is not a factor of f(x).

Part 2:

We must find out if [tex]x^2+5x+6[/tex] is a factor of [tex]x^4+5x^3+2x^2-20x-24[/tex] without using long division or synthetic division.

We can use the polynomial remainder theorem again, but since the factor is not in the form (x-a), we can factor it as follows:

[tex]x^2+5x+6 =(x+2)(x+3)[/tex]

Now we just apply the theorem twice. If both remainders are zero, then the assumption is true.

Let's make:

[tex]f(x)=x^4+5x^3+2x^2-20x-24[/tex]

Find f(-2):

[tex]f(-2)=(-2)^4+5(-2)^3+2(-2)^2-20(-2)-24[/tex]

[tex]f(-2)=16-5*8+2*4+40-24 =16-40+8+40-24=0[/tex]

Find f(-3):

[tex]f(-3)=(-3)^4+5(-3)^3+2(-3)^2-20(-3)-24[/tex]

[tex]f(-3)=81-5*27+2*9+60-24[/tex]

[tex]f(-3)=81-135+18+60-24 =0[/tex]

Since both f(-2) and f(-3) are zero, [tex]x^2+5x+6[/tex] is a factor of [tex]x^4+5x^3+2x^2-20x-24[/tex].

Step-by-step explanation:

The other person is correct.

Answer:

[tex]R= 2.6[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 40e^{.06t[/tex]

[tex][a,b] = [0,3][/tex]

Required

Determine the average rate of change (R)

This is calculated as follows:

[tex]R = \frac{f(b) - f(a)}{b - a}[/tex]

Where

[tex]a = 0[/tex] and [tex]b = 3[/tex]

Substitute 0 for a and 3 for b

[tex]R = \frac{f(3) - f(0)}{3 - 0}[/tex]

[tex]R = \frac{f(3) - f(0)}{3}[/tex]

[tex]R = \frac{1}{3}[f(3) - f(0)][/tex]

Calculate f(3)

[tex]f(x) = 40e^{.06t[/tex]

[tex]f(3) = 40e^{.06*3}[/tex]

[tex]f(3) = 40e^{0.18}[/tex]

[tex]f(3) = 40 * 1.197[/tex]

[tex]f(3) = 47.88[/tex]

Calculate f(0)

[tex]f(x) = 40e^{.06t[/tex]

[tex]f(0) = 40e^{.06*0}[/tex]

[tex]f(0) = 40e^{0}[/tex]

[tex]f(0) = 40*1[/tex]

[tex]f(0) = 40[/tex]

So, the expression:

[tex]R = \frac{1}{3}[f(3) - f(0)][/tex]

[tex]R= \frac{1}{3}[47.88 - 40][/tex]

[tex]R= \frac{1}{3}[7.88][/tex]

[tex]R= 2.62666666667[/tex]

[tex]R= 2.6[/tex]

Hence, the average rate of change is approximately 2.6
