If 2x/2y= 16, what is x-y

Answers

Answer:

15

Step-by-step explanation:

2x/2y = 16

First, we can cancel out the 2s as there is one on the numerator and another on the denominator.

x/y = 16

To make it fraction form, we know that 16 = 16/1.

x/y = 16/1

We then get x and y.

x = 16

y = 1

x - y = 15

1,428
1,476
2,856
2,952

Answers

Answer:

B

Step-by-step explanation:

This is a summation problem. The difference is the same all the way up.

First we have to find the last term.

t24 = a + (n - 1)*d

a = 4

n = 24

d = 5

t24 = 4 + (24 - 1)*5

t24 = 4 + 23*5

t24 = 4 + 115

t24 = 119

Now you can calculate the total

Sum = (a + t24)*n/2

Sum = (4 + 119)*24/2

Sum = (4 + 119)*12

Sum = 123 * 12

Sum = 1476

The length of a rectangle is 2cm greater than the width. If the width is increased by 4cm, the area is increased by 88cm^2. Find the original dimensions of the rectangle

Answers

Step-by-step explanation:

l = length

w = width

l = w + 2

l×w = area = (w + 2)×w = w² + 2w

l×(w + 4) = area + 88

(w + 2)×(w + 4) = w² + 2w + 88

w² + 6w + 8 = w² + 2w + 88

6w + 8 = 2w + 88

4w = 80

w = 20 cm

l = w + 2 = 20 + 2 = 22 cm

the original length is 22 cm.

the original width is 20 cm.

the original area (22×20) is therefore 440 cm².

the new area (22×24) would be 528 cm².

Find g(x), where g(x) is the reflection across the x-axis of f(x)=x2.
Write your answer in the form a(x–h)2+k, where a, h, and k are integers.

Answers

Answer:

Step-by-step explanation:

4.0/5

7

The graph of f(x) = x in a straight line passing through the origin (0,0) and  at an angle of 45 degrees to the x axis. It increases from left to right.

Reflection in the x axis  will convert all positive values of f(x) to negative values of f(x)  and vice versa.  

g(x)  = - x     and is a striaght line passing through origin  at angle of 45 degrees but the slope descends from left to right.

The reflection of function f(x) = x² across the x-axis is given by,

g(x) = -(x - 0)² + 0.

Use the concept of fucntion defined as:

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

Given that,

Function: f(x) = x²

Desired reflection function: g(x)

Reflection of f(x) across the x-axis gives g(x)

Need to find g(x) in the form a(x - h)² + k, where a, h, and k are integers.

To find the reflection across the x-axis of the function f(x) = x²,

Negate the function's y-values.

So, for g(x), the reflection of f(x) across the x-axis,

g(x) = -f(x)

g(x) = -x²

To write this in vertex form, complete the square. Let's begin:

g(x) = -x²

g(x) = - (x²)

g(x) = -1 (x²)

Now, to complete the square,

Take half of the coefficient of x, square it, and add it inside the parentheses:

g(x) = -1(x²)

Taking half of the coefficient of x, we get -1/2.

Squaring it gives 1/4.

Adding this inside the parentheses, we have:

g(x) = -1(x² + 1/4)

To maintain symmetry,

Write the expression inside the parentheses as a perfect square:

g(x) = -1(x² + 1/4)

g(x) = -1(x²  + (1/2)²)

Now, factoring out the -1, we get:

g(x) = -(x²+ (1/2)²)

Finally, we can rewrite this expression in the form a(x - h)² + k:

g(x) = -(x - 0)² + 0

Hence, the reflection of f(x) = x² across the x-axis is given by,

g(x) = -(x - 0)² + 0.

How to write the expression for a growing exponential?

The growing exponential can be written generally as f(x) = N(1 + r)ˣ, where N is the initial value and r is the rate of growth.

To find the expression different values of x and f(x) should be known.

Given that,

The value of the stock in 1940 is $1.25.

And, its rate of growth per year is 7%.

The general expression for the growing exponential can be written as,

f(x) = N(1 + r)ˣ

The given data shows N = 1.25 and r = 7/100 = 0.07.

Thus, the required expression can be written as,

V(t) = 1.25(1 + 0.07)^t

Hence, the required expression for representing the value of the stock V(t), in dollars, t years after 1940 is V(t) = $1.25(1 + 0.07)^t.

The percentage of students who do not travel by car is given by the equation A = 44 %

The mean number of students in each car is 2 students and the missing frequency is 3 cars

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The total number of students in the school = 25 students

The number of students who travel by car = 14 students

The number of students who do not travel by car = 11 students

So , the percentage of students who do not travel by car = ( number of students who do not travel by car x total number of students in the school ) x 100

Substituting the values in the equation , we get

The percentage of students who do not travel by car A = ( 11/25 ) x 100

On simplifying the equation , we get

The percentage of students who do not travel by car A = 0.44 x 100

The percentage of students who do not travel by car A = 44 %

And , the missing frequency is f = 3 cars

The total number of students in one car = 1 + 2 + 3 = 6 students

So , the mean number of students in each car = 6/3 = 2 students

Hence , the equations are solved
