A number x divided by 18 is equal to 4.6

Answers

Answer:

x is 84.

Step-by-step explanation:

this is because 84 divided by 18 equals 4.6

hope this helped :D

Answer:

if you're looking for the value of x: a number x/18=4.6 x=82.8

Step-by-step explanation:

it's a one step equation: x is being divided by 18 to get 4.6, so to get x by itself, multiply by 18 on the left side because (x/18) * 18 = x, but what you do to one side you have to do to the other, so then multiply 4.6 by 18 also to get x=82.8.

What does it mean to get 150% salary raise? Explain in words and then give an example showing calculation.

Answers

To get a 150% salary raise, you’re increasing the amount of money in your raise. For example, if your salary is 15,000 you would set up an inequality part/whole = %/100 So in this situation x is what we’re trying to find. X/15,000=150/100 which is 22,500 which we add to the salary. 15,000+22,500=37,500

Answer:

y = -2x + 17

Step-by-step explanation:

The line is parallel to 4x + 2y = 10, and parallel lines have the same slope. Let's convert this line into slope intercept form:

2y = 10 - 4x,

y = -2x + 5

So the slope of this line and our line [the line which we want to determine in slope intercept form] is -2

Given the point (7, 3) and slope -2 we can solve for the y-intercept;

y = mx + b,

3 = -2(7) + b,

-14 + b = 3,

b = 17

Your solution is y = -2x + 17 (First option)

Please answer, Thank you.

Options A and B are the correct answer.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

From the graph,

We can have two coordinates:

(x, 0) and (0, y)

Now,

Slope.

= (y - 0)/(0 - x)

= y/-x

= - y/x

Now,

The slope is a negative value.

This means,

-2 and -8/5 can be the slope.

Thus,

The slope of the line is -2 or -8.5.

What is the domain of g?

Answers

Answer:

Solution. The domain of g(x) consists of all real numbers except x = 32, since that input value would cause us to divide by 0. Likewise, the domain of f consists of all real numbers except 1. So we need to exclude from the domain of g(x) that value of x for which g(x) = 1.
