Answer:

9/140

Step-by-step explanation:

9/20⋅5/35

Factor the number: 35= 5⋅7

9/20⋅5/5⋅7

Cancel the common factor: 5

9/20⋅1/7

Apply the fraction rule

9⋅1/20⋅7

Answer:

x<6

Step-by-step explanation:

b. x≤6

so the empty circle means it's (in this case) less than or equal to 6. the < looks like an L, so think, L is for Less than. Also, the < looks like part of <-, so that's the way the arrow points! hope this helps, good luck!

Answer:

Step-by-step explanation:

x+y=180; y+z=180

145+z=180

z= 35

y=180-35

y =145

x=180-145

x= 35

Answer:

y = 40x + 30

Step-by-step explanation:

The equation for a linear function is given by:

y = mx + b;

where y and x are variables, m is the slope or rate of change of the function and b is the initial value of y at x = 0 (that is y intercept).

Let y represent the total cost and x represent the number of hours worked.

The electrician charges 110 after 2 hours of work and 190 for 4 hours of work.

Representing in coordinate form as (x, y) we get:

(2, 110) and (4, 190)

The equation of the function can be gotten using the formula:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Therefore:

[tex]y-110=\frac{190-110}{4-2}(x-2)\\\\y-110=40(x-2)\\\\y-110=40x-80\\\\y=40x-80+110\\\\y=40x+30[/tex]

Answer:

5x3+9x2+15x+27

Step-by-step explanation:

The expression that is equivalent to (mn)(x) is 5x³ + 9x² + 15x + 27.

Option A is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example: so

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To find the product of m(x) and n(x), we need to multiply the two polynomials term by term:

m(x) = x² + 3

n(x) = 5x + 9

mn(x) = (x² + 3) (5x + 9)

Multiplying the two polynomials using the distributive property.

mn(x) = 5x³ + 9x² + 15x + 27

Thus,

The expression that is equivalent to (mn)(x) is 5x³ + 9x² + 15x + 27.

Answer:

y=8x+7

Step-by-step explanation:

Use the form y=mx+b

M= the slope

B= the y-intercept

y=8x+?

Since the y coordinate of (0,7) is 7

b=7

So y=8x+7

Answer:

No.

Step-by-step explanation:

Your line should start at the point (0,-4) and move up 3 and over 1. The next point should be at (1,-1).

Answer:

This is not correct

Explanation:

To show this, I will use the equation y = 3x - 4.

Let's say that x = 3

In this case, 3x = 9

9 - 4 = 5

So y = 5

Since I can see you have the line hitting 3 on the x axis and the line hitting 2 on the y axis in the same spot, the line is not corresponding with the equation.

So if the line is at 0 on the x-axis, it should be -4 on the y-axis

If it is 1 on the x-axis, it should be -1 on the y-axis

And so on and so forth

Answer:

WY = 12 units.

Step-by-step explanation:

Given the number line

The distance between W and Y can be calculated such as:

WY = [Location of Y] - [Location of W]

WY = [7] - [-5]

WY = 7+5

WY = 12

Therefore, WY = 12 units
