Answer:

Craig earns $1,200 each month

Explanation:

We are given that Craig pays a total of $720 each year for his telephone service

We also know that a year has 12 months

This means that:

Craig pays [tex]\frac{720}{12}= 60[/tex] dollars each month for his telephone services

We are given that the monthly phone bill is [tex]\frac{1}{20}[/tex] of his monthly earnings

Assume that his monthly payment is x

We have:

[tex]\frac{1}{20}x = PhoneBill\\ \\ \frac{1}{20}x = 60\\ \\   x=60*20 = 1200[/tex] dollars

Hope this helps :)

Craig earns about $1200 each month and pays a total of $720 each year for his telephone service.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the amount earned each month

Hence:

(1/20)x * 12 months = 720

x = 1200

Craig earns about $1200 each month and pays a total of $720 each year for his telephone service.

Answer:

f(1/3) = 1

Step-by-step explanation:

Given

f(n)=3n

We have to find f(1/3).

In order to find the value of the given function at a point, we put the value in the function where the variable is used.  

i.e. to find f(2) for f(x); x will be replaced by 2 in the function. Similarly to find f(1/3), we will replace n by 1/3 in the function.

So to find  

f(1/3)=3*  1/3

=1

So, the value of f(1/3) is 1 ..

Answer: Hello there!

The system of equation given is:

y = x^2-4

y = -2x-5

And we want to solve this system:

the first step we can do is replace y in the first equation by the given in the second equation:

y = x^2-4 = -2x - 5

now we can solve it for x:

x^2-4 +2x + 5 = 0

x^2 +2x + 1 = 0

and now we can use the cuadratic equation forumla:

this is, if we have a function of the form:

ax^2 + bx + c = 0

the solutions are:

[tex]x = \frac{-b +/- \sqrt{b^2 -4ac} }{2a}[/tex]

in our equation we have a=1, b = 2 and c= 1

we replace it in the formula given, and we obtain:

[tex]x = \frac{-2 +/- \sqrt{2^2 -4*(1)} }{2} = \frac{-2 +/- \sqrt{4 - 4} }{2} = -2/2 = -1[/tex]

Now we got the value of x, and we could replace it in one of the equations and get the value of y:

y = -2x-5

y = -2*(-1) - 5 = 2 -5 = -3

then the pair is (-1, -3)

and the correct option is D.

The length of height of the box is 7 inches.

A quadrilateral is a shape with four sides, four vertices, and four angles that is only two dimensional. Convex and concave are the two main forms. Convex quadrilaterals can also be divided into a number of subgroups, including trapezoids, parallelograms, rectangles, rhombus, and squares.

Given that,

Length of box = 6 in.

Width of box   = 6 in.

Volume of box = 252 square in.

Since the length and width of box are same,

Therefore its shape is cuboid.

We know that volume of cuboid = length x width x height

Therefore,

Height of the box = volume/(length x width)

                             = 252/(6x6)

                             = 7 in.

Hence, the required height = 7in.

The first term is,  x2  its coefficient is  1 .

The middle term is,  +8x  its coefficient is  8 .

The last term, "the constant", is  +15

Answer:

i think its A if it isnt im sorry

Step-by-step explanation:

Answer:

The second option :: V = [tex](25-2x)(20-2x)x[/tex] is correct.

Step-by-step explanation:

The vertical side was 25 inches before cutting out the corners.  

The horizontal side was 20 inches before cutting out the corners.

So now, if you fold all of the corner up, you get a box that has a height of "x".  

The sides are now missing a length of x from each end.  

So the longer edges of the box are now [tex](25-2x)[/tex] inches

The shorter edges of the box are now [tex](20-2x)[/tex] inches

The volume of a box is given by V = length x width x height

So, here the volume becomes:

V = [tex](25-2x)(20-2x)x[/tex] cubic inches.

Answer:

The three friends took 6p + 5 peaches home

Explanation:

We are given that the three friends picked 2p, 4p+3 and 3p+2 peaches

This means that:

Total picked = 2p + 4p + 3 + 3p + 2 = 9p+5 peaches

Now, we know that the owner will take p peaches from each of the three friends

This means that:

Amount taken by owner = 3p peaches

Finally, to get the amount that the three friends will take home, we subtract the amount that the owner will take from the total amount they picked

This means that:

Number of peaches they took home = total picked - amount taken by owner

Number of peaches they took home = 9p + 5 - 3p

Number of peaches they took home = 6p + 5 peaches

The answers are:

- The quantity that represents the initial number of bacteria is 64.

- The quantity that represents the rate at which the number of bacteria is increasing is (1+0.12) or 1.12 which means the growth rate percentage for the bacteria is 0.12 or (0.12*100), it will be 12%.

To solve the problem, and complete the statements, we need to remember the form of the exponential growth.

The exponential growth formula is given by the following formula:

[tex]P(t)=StartAmount(1+PercentageRate)^{t}[/tex]

Where,

Start Amount, is the starting population or amount.

(1+Percentage Rate), is the increasing rate

Percentage Rate, is the growth rate percentage.

t, is the time elapsed.

Now, we are given the following expression:

[tex]P(3)=64(1.12)^{3}[/tex]

Which can be rewrited as:

[tex]P(3)=64(1+0.12)^{3}[/tex]

So, we have that:

- The quantity that represents the initial number of bacteria is 64.

- The quantity that represents the rate at which the number of bacteria is increasing is (1+0.12) or 1.12 which means the growth rate percentage for the bacteria is 0.12 or (0.12*100), it will be 12%.

Answer:

The merchant should mix 53.33 pounds of cheaper cacao and 26.67 pounds of costlier cacao.

Step-by-step explanation:

A merchant wants to blend 80 pounds of cacao worth $9.00 a pound from two kinds: one at $11.40 a pound and the other at $7.80 a pound.

Let the number of pounds of cheaper cacao be x

Let the number of pounds of costlier cacao be y

The merchant wants total pounds = 80

So, first equation becomes:

[tex]x+y=80[/tex] or [tex]x=80-y[/tex]

Now values of per pounds become [tex]7.80x[/tex] and [tex]11.40y[/tex]

As the merchant wants the mixture worth $9 so second equation becomes:

[tex]7.80x+11.40y=9(80)[/tex]

=> [tex]7.80x+11.40y=720[/tex]

Substituting [tex]x=80-y[/tex] in second equation, we get

[tex]7.80(80-y)+11.40y=720[/tex]

=> [tex]624-7.80y+11.40y=720[/tex]

=> [tex]3.60y=96[/tex]

[tex]y=26.67[/tex] pounds

We know, [tex]x=80-y[/tex]

=> [tex]x=53.33[/tex] pounds

So, The merchant should mix 53.33 pounds of cheaper cacao and 26.67 pounds of costlier cacao.

We can check this:

[tex]53.33(7.80)+26.67(11.40)=720.012[/tex] dollars

Answer:

The correct answer is (D) slope=-3 and y-intercept=-2

Step-by-step explanation:

Answer:

f(x) = x + 4

Step-by-step explanation:

Given

y - x - 4 = 0 ( add x to both sides )

y - 4 = x ( add 4 to both sides )

y = x + 4 ( let y = f(x) )

f(x) = x + 4

-4 is the slope........

Answer:

4

Step-by-step explanation:

To find slope, we will rewrite this equation into slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept,

- 4x + y = -1

+ 4x         +4x

y= -1 + 4x

y=4x - 1

Answer:

W = 7.5 in

Step-by-step explanation:

We'll use the formula for the perimeter of a rectangle:  P = 2W + 2L.

Here, L = W + 5, so P = 2W + 2L becomes:

P = 2W + 2(W + 5), and this equals 40 in.

Thus we have the equation in W (the desired variable) as follows:

2W + 2(W + 5) = 40 in, or 4W + 10 = 40.

Then 4W = 30, and W = 7.5 in.

Based on the perimeter of this rectangle, the width is 7.5 inches.

The perimeter of a rectangle is calculated by:

= Length + Width + Length + Width

Assuming the width is denoted by x, the length would be:

Length = 5 + Width

Length = 5 + x

The perimeter is given so we can solve for the width:

Length + Width + Length + Width  = Perimeter

5 + x + x + 5 + x + x = 40

10 + 4x = 40

4x = 40 - 10

x = 30/4

x = 7.5 inches

In conclusion, the width is 7.5 inches.

This graph is not a straight line .

It is a non-linear function.

y=3 and y=13 are also straight lines.

The correct choice is C.

Answer:

{-2, -14, -26, -50}

Step-by-step explanation:

The range of the function is the function evaluated at each point of the given domain. So to find the range of the function we need to find the value of the function for each point in the domain:

- For x = -8

[tex]f(x)=-2x-18[/tex]

[tex]f(-8)=-2(-8)-18[/tex]

[tex]f(-8)=16-18[/tex]

[tex]f(-8)=-2[/tex]

The first value of the range of the function is -2

- For x = -2

[tex]f(x)=-2x-18[/tex]

[tex]f(-2)=-2(-2)-18[/tex]

[tex]f(-2)=4-18[/tex]

[tex]f(-2)=-14[/tex]

The second value of the range is -14

- For x = 4

[tex]f(x)=-2x-18[/tex]

[tex]f(4)=-2(4)-18[/tex]

[tex]f(4)=-8-18[/tex]

[tex]f(4)=-26[/tex]

Th third values of the range is -26

- For x = 16

[tex]f(x)=-2x-18[/tex]

[tex]f(16)=-2(16)-18[/tex]

[tex]f(16)=-32-18[/tex]

[tex]f(16)=-50[/tex]

The fourth and last value of the range is -50

Now we can put all the values of the range together

The range of the function is {-2, -14, -26, -50}
