how do i solve Solve 4/9=x/45.

Answers

You multiply 45 on both sides and get x=20

Answer:

x = 20

Step-by-step explanation:

I would say that there are two ways to solve this.

First way:

You could simply this equation be cross multiplying.

4/9 = x/45 → 180 = 9x

Next, divide 180 by 9.

20 = x → x = 20

Second way:

Considering that fraction bars mean division, you could cancel out x/45 by multiplying both fractions by 45.

4/9 = x/45 → 20 = x → x = 20

Answers

Answer:

Step-by-step explanation:

Answer: The error made was that the x from 24xy wasn’t taken out. Because if you multiplied 6x and -4xy it would NOT equal -24xy. So what she should done was also 6x(3-4y)

What is a number line?

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series. The endpoints of this line go on forever. Some will have a defined beginning and end. It refers to those as closed number lines. Number lines might be alternatively left empty or blank. A number ladder is a vertical number line.

Given;

we have number line that can be used to find the distance between (–1, 2) and (–5, 2)

The y-coordinates of the points are the same, therefore the distance between those points will be the difference of the x-coordinates. The first number line shows those x-coordinates plotted properly which can be used can be used to find the difference between them.

Therefore the correct answer is option A

There are 2 mixtures of light purple paint. Mixture A is made with 5 cups of purple paint and 2 cups of white paint. Mixture B is made with 15 cups of purple paint and 8 cups of white paint. Which mixture is a lighter shade of purple? Explain your reasoning. *

Answers

Answer:

Mixture B

Step-by-step explanation:

The mixture with more white paint would have a lighter shade of purple.

Mixture A is 2/7 white paint while Mixture B is 8/23 white paint.

2/7 is approximately 0.286

8/23 is approximately 0.348

0.348 > 0.286 so Mixture B is made of more white paint than Mixture A and therefore is a lighter shade of purple.

Step-by-step explanation:

To get started: You must subtitude the blank with X/variables, to get solving.

23+15=x+23

Step 1: Simplify both sides of the equation.

23+15=x+23

(23+15)=x+23(Combine Like Terms)

38=x+23

Step 2: Flip the equation.

x+23=38

Step 3: Subtract 23 from both sides.

x+23−23=38−23

x=15 (Final answer)

What is a function?

"A function is a process or a relation that associates each element 'a' of a non-empty set A , at least to a single element 'b' of another non-empty set B. A relation f from a set A (the domain of the function) to another set B (the co-domain of the function) is called a function in math. f = {(a, b)| for all a ∈ A, b ∈ B}

A relation is said to be a function if every element of set A has one and only one image in set B.

Here, the given function is y = - 2x.

When the value of 'x' is - 2, the value of 'y' is

= - 2(- 2) = 4.

When the value of 'x' is - 2, the value of 'y' is

= - 2(0) = 0.

When the value of 'x' is 2, the value of 'y' is

= - 2(2) = - 4.

Therefore, the set of values of for the given function are (- 2, 4), (0, 0), (2, -4).

What are some rules for function transformations?

Suppose we have a function f(x).

f(x) ± d = Vertical upshift/downshift by d units (x, y ±d).

f(x ± c) = Horizontal left/right shift by c units (x - + c, y).

(a)f(x) = Vertical stretch for a > 0, vertical shrink a < 0. (x, ay).

f(bx) = Horizonatal compression b > 0, horizontal stretch for b < 0. (bx , y).

f(-x) = Reflection over y-axis, (-x, y).

-f(x) = Reflection over x-axis, (x, -y).

Given, A parent function f(x) = x.

Now, The transformed function g(x) = 2x is a horizontal compression of 2 units.

I'm sorry, I don't know how to put the graph in. BTW, This was on Iready

Answers

Answer: you can add the image below this and send the pic then I will anwser it for you.

Step-by-step explanation:

Dan’s productivity is constant as slope of the straight line remains constant.

What is the general equation of a Straight line?The general equation of a straight line is -

y = mx + c

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

Other possible equations of line are -

(y - y₁) = m(x - x₁) {Point - slope form}(y - y₁) = (y₂ - y₁) × (x - x₁)/(x₂ - x₁) {Two point - slope form}x/a + y/b = 1 {intercept form}x cos(β) + y sin(β) = L {Normal form}

We have a graph as shown in the image that depicts how many identical cars Dan builds and sells them online.

Let the two points be (2, 3) and (4, 6). Then, the slope will be -

m = (6 - 3)/(4 - 2) = 3/2 = 1.5

Yes, Dan’s productivity is constant as the graph is a straight line and its slope remains constant which depicts Dan's productivity.

Therefore, Dan’s productivity is constant as slope of the straight line remains constant.
