Answer:

3 or (0,3)

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

a)  x represents the number of years since 2004 this means that x = 0 represent the year 2004, y represent the number of catalogs. From the table the numbers of catalogs in 2004 are y-intercepts and the slope is the growth rates. Hence the equations are:

y = 1293x + 7440           (1)

y = -1364x + 3805         (2)

b)

y = 1293x + 7440           (1)

y = -1364x + 3805         (2)

Subtract equation 2 from equation 1 to get:

0 = 2657x + 3635

2657x = -3635

Divide through by 2657

x = -1.368

Put x = -1.368 in equation 1:

y = 1293(-1.368) + 7440

y = 5671.1

This means that about 1.4 years before 2004, the number of catalogs where 5671

Answer: $69

Step-by-step explanation:

Sales tax is charged after the discount.

The calculator was originally $75 and there is a 20% discount.

The discounted price is:

= 75 * (1 - 20%)

= 75 * 0.8

= $60

Now the sales tax applies. Total cost is:

= 60 * (1 + 15%)

= 60 * 1.15

= $69

About 527.79

Step-by-step explanation:

formula is A=2πrh+2πr^2

Answer:

[tex]527.52\:\mathrm{in^2}[/tex]

Step-by-step explanation:

The surface area of this cylinder consist of two circles and a 3D outer edge with respect to the circumference. The area of a circle is given as [tex]r^2\pi[/tex]. Using [tex]\pi=3.14[/tex] as requested in the problem, the area of both these circles is:

[tex]2\cdot6^2\cdot 3.14=226.08\:\mathrm{in^2}[/tex].

The area of the outer edge is the circumference of the circle multiplied by the height. The circumference of a circle is given by [tex]2r\pi[/tex].

Therefore, the circumference's 3D outer edge is:

[tex]8\cdot2\cdot6\cdot 3.14 = 301.44\:\mathrm{in^2}[/tex].

Adding these up, the total surface area is:

[tex]226.08+301.44=\fbox{$527.52\:\mathrm{in^2}$}[/tex].

Answer:

64.93=4.73x+22.36

Step-by-step explanation:

64.93 is how much he paid

22.36 is his constant

4.73 is for 1 call

Answer:

4 feet and 11 1/4 inches left

Step-by-step explanation:

5 feet - 1 foot leaves 4 feet

1 foot - 3/4 = 11 1/4

so, 4 feet and 11 1/4 inches left

Answer:

It will be 57-2.5h=32

This is because you're starting with 57 degrees. 2.5 is constant so that is why you need a variable for it.

Answer:

I would say 57 - 2.5h = 32

Step-by-step explanation:

Because the temperatures is dropping so that why we are subtracting and we don't no how many hours are theirs every time it drops for 2.5 that why we put the h with the 2.5

Answer:

$0.26388 per oz ; $0.28225 per oz

Step-by-step explanation:

Given :

Option 1:

$4.75 for 18 oz

Option 2:

$11. 29 for 40 oz

The price per ounce (oz) for each option is :

Price / number of ounce

Option 1:

4.75 / 18 =

Price per ounce = $0.26388 per oz

Option 2:

$11.29 / 40 oz

= $0.28225 per oz

Step-by-step explanation:

~Simplify the expression~

Answer:

f(2)=2²-5×2+7=4-10+7=-6+7=1

Step-by-step explanation:

If the perimeters could be equal,

then 4(x + 3) = 2(x + 4 + x + 1).

=> 4x + 12 = 2(2x + 5)

=> 4x + 12 = 4x + 10

However 12 =/= 10 for all real values of x. Hence their perimeters can never be equal.

Answer:

Option b

multiply 6 and 4

Answer:

The solutions for both system of equations are as follows:

Step-by-step explanation:

The first set of equations is:

[tex]4x+6y=32\\3x-6y=3\\[/tex]

It can clearly be seen that the coefficients of y are already same in magnitude with different signs so we have to add both equations

So adding both equations, we get

[tex]4x+6y+3x-6y = 32+3\\7x = 35\\\frac{7x}{7} = \frac{35}{7}\\x = 5[/tex]

Putting x=5 in equation 1

[tex]4(5)+6y = 32\\20+6y = 32\\6y = 32-20\\6y = 12\\\frac{6y}{6} = \frac{12}{6}\\y = 2[/tex]

The solution is (5,2)

The second set of simultaneous equations is:

[tex]-3x+5y=-113x+7y=-1[/tex]

We can see that the coefficients of x in both equations are same in magnitude with opposite signs so

Adding both equations

[tex]-3x+5y+3x+7y = -11-1\\12y = -12\\\frac{12y}{12} = \frac{-12}{12}\\y = -1[/tex]

Putting y= -1 in first equation

[tex]-3x+5(-1)=-11\\-3x-5=-11\\-3x=-11+5\\-3x=-6\\\frac{-3x}{-3} = \frac{-6}{-3}\\x = 2[/tex]

The solution is: (2,-1)

Hence,

The solutions for both system of equations are as follows:

Answer:

slope = (4,7)

Step-by-step explanation:

The answer to this question is 32

Explanation

16/30 cross multiplies x/60

after you get, 960=30x

then divide by 30 and then you get 32.

or you can just take 16 and multiply it by two since 60 is a multiple of 30.
