what is 15 meters decreased by 60%

Answer:

Step-by-step explanation:

The inverse is found by interchanging the x and y values and solve the result for y.

I will use y for f(x)

y = 4x^2

Inverse

x = 4y^2              Divide by 4

x/4 = 4y^2 /4    

x/4 = y^2             Take the square root of both sides.

sqrt(x/4) = sqrt(y^2)

y = sqrt(x/4)

g(x) = sqrt(x/4)  If you have a very fussy teacher, the inverse function could be written as

g(x) = +/- sqrt(x)/2

I expect that if the question is computer marked, I would try g(x) = sqrt(x)/2 first.

The system of equations that can be used to determine the rates of each type of service are:

45x + 50y = $27.75

70x + 30y = $36.

Simultaneous equations are sets of equations that have to be solved together or at the same time in order to determine the required values. The two above equations have to be solved together in order to determine the cost of the peak and nonpeak services.

The methods that can be used to solve simultaneous equations are:

Here is the complete question: The price of a cellular telephone plan is based on peak and non-peak service. Kelsey used 45 peak minutes and 50 non-peak minutes and was charged $27.75. That same month, Austin used 70 peak minutes and 30 non-peak minutes and was charged $36. Write a system of equations that can be used to determine the rates for each type of service.

Use x for peak minutes and y for non-peak minutes.

Answer:

slope (m) = -8.

Step-by-step explanation:

Slope-intercept form is y = mx + b, in which:

m = slope

b = y-intercept

x = (x , y)

y = (x , y)

~

With the given information on top, it means that -8 is your answer.

~

Hey, There !

Your answer will be is :

slope (m) = -8

The "slope-intercept" is form is y = mx + b, when m is the slope and b is the y-intercept.

[tex]y~=~mx~+~b[/tex]

Using the slope-intercept form, the slope is -8

[tex]m~=~-8[/tex]

Answer:

22

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable. x = 22

Answer:

22

Step-by-step explanation:

The diagonals are divided into 2 parts. They're both equal to each other in order to equal the total length.

Setting them up to equal each other is the easiest way to solve.

2x + 18 = x + 40.

Now with simple algebra, we can find the sidelength of x.

Subtract both sides by x.

x + 18 = 40

Subtract both sides by 18.

x = 22.

Answer:

a₃ = 135

Step-by-step explanation:

using the recursive rule and a₁ = [tex]\frac{5}{3}[/tex] , then

a₂ = a₁ × - 9 = [tex]\frac{5}{3}[/tex] × - 9 = 5 × - 3 = - 15

a₃ = a₂ × - 9 = - 15 × - 9 = 135

Answer:

135

Step-by-step explanation:

since this is a recursive formula it shows that 5/3 is our 1st term and the common ration is -9 see: Step 1. a(1)=5/3  a(2) = Step 2. a(1)x-9=-15

Step 3. a(3) = -15x9=135 i hope this helps :D bye have a good day!!!!

The cost for one steak burger is $4.5. The price/ The cost of one order of fries is $2.25

Let one steak burger cost $x

and one fries order cost $y

Hence, we have

3x+2y = 18-----------1

2x+3y = 15.75-------2

multiply equation 1 by 2 and equation 2 by 3

6x + 4y = 36 ---------3

6x +  9y = 47.25 ----4

subtraction 4 from 3 we have

0x -5y = -11.25

Divide both sides by -5

y = 11.25/5

y = $2.25

Put y = 2.25 in equation 1 to find x

3x+2(2.25) = 18-----------1

3x + 4.5 = 18

3x = 18 -4.5

3x = 13.5

Correct response:

The given parameters are;

Dimensions of apples in the rectangular base = 7 apples by 5 apples

Number of apples on which each apple above rests = 4 apples

Required:

The number of apples in the stack.

Solution:

The dimensions, length and width of the apples in each row decreases

by 1 compared to the row on which the apple rests, as follows;

In the base, the dimension = 7 by 5

In the row directly above, the dimension = (7 - 1) by (5 - 1)

The number of apples sequence continues and is completed by a singles row of apples at the top, from which gives;
