Answer:

6.5 rounded from 6.53...

to see if this is correct we can:

13.5+9.5+6.5*3 = 42.5

but since we rounded it we can say its 6.5

Answer:

6.55 meters each day

Step-by-step explanation:

You know that in the end the fence must be 42.6 meters long.

On Monday & Tuesday, he installed 22.95 meters of fence. (We know this because 13.45 + 9.5 = 22.95).

So, how much is left? You find that by subtracting 22.95 from 42.6.

42.6-22.95 = 19.65 meters

There are 3 days left of fencing, and these days he will install equal lengths, so you can divide 19.65 meters by 3 days.

19.65 / 3 = 6.55 meters of fence per day

x² - 9 / х^2 - 3x

Answers

Answer:

[tex]\frac{x+3}{x}[/tex]

Step-by-step explanation:

Factorise numerator and denominator

x² - 9 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

x² - 9

= x² - 3² = (x - 3)(x + 3)

x² - 3x ← factor out x from each term

= x(x - 3)

Then

[tex]\frac{x^2-9}{x^2-3x}[/tex]

= [tex]\frac{(x-3)(x+3)}{x(x-3)}[/tex] ← cancel common factor (x - 3) on numerator/denominator

= [tex]\frac{x+3}{x}[/tex]

Find the equation (in terms of x) of the line through the points (-2,3) and (4,-9)
y =

Answers

Answer:

y =5

Step-by-step explanation:

m=

−9−7

5−5

=

−16

0

=0

y=mx+b

5=(0)(7)+b

b=5

therefore y = 5

Answer:  y = -2x - 1

Step-by-step explanation:

We can calculate the slope from the two given points.  Slope is the change in y per the change in x, sometimes called the rise (y) over the run (x)

Rise is (-9 -3) = -12

Run is (4 - (-2)) = 6

Slope = Rise/Run = -12/6 = -2

The line is y = -2x + b

Find b by using either of the two known points (solutions).  I'll choose (-2,3) [because I like smaller numbers]

y = -2x + b

3 = -2*(-2) + b

b = -1  [That was only slightly easier than -9 = -2*(4) + b; b = -1]

The equation is y = -2x - 1

This is the only question I cant answer somebody help me please and thank you

Answers

Answer:

d.

Step-by-step explanation:

The answer to this question would be A. But why? First you see the point on (-2,3) and than it asks for you to rotate the point 90 degrees. Now, this is where things get tricky because it doesn’t specifically ask for any sort of rotation and in seeing this we assume they mean clock wise because they didn’t state otherwise. So after rotating the point 90 clockwise we land at the point (2,3). I hope this helps!

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

Let h represents the hourly fee.

Let C be the total charge and t be the rental time in hours.

C = ht + 43

Putting the given values into the equation, we get:

64 = 7h + 43

7h = 21

h = 3

Therefore, the hourly fee is $3.00 per hour.

Larry Gold’s gross pay for this week as a stock clerk for Hensley’s is $375.15. He is single and claims 2 allowances. Using the percentage method of withholding, what is his withholding for federal income tax?

Answers

Larry gold is withholding $22.38 in federal tax income.

The federal government and the majority of states in the US impose income taxes.

Applying a tax rate to taxable income, which is the entire income less permissible deductions, yields the income taxes, which may rise as income rises. Income is a broad concept. Estates and trusts may be subject to taxation on income that has not been dispersed, in addition to individuals, corporations, and the government. (With a few exceptions for Federal income taxation) Partnerships are not subject to taxation; however, the partners of a partnership are. While nonresidents are solely subject to local taxes, residents and citizens are subject to worldwide taxes. Numerous credit kinds lower taxes, and some credit types may even be more than taxes before credits. There is an alternative tax.

Given that Larry gross pay for this week is $375.15

Now we know from the income tax table that the withheld tax is calculated by calculating 6% of the gross pay when there are 2 allowances.

Tax  = 6% of 375.15 = 22.38

Hence the withholding for federal income tax is $22.38 .

the question is kinda incomplete

when writing the equation of a line in slope-intercept form, how can you determine the value of m in y=mx+b if you know the coordinates of two points on the line?

Answers

To determine the value of m in the equation, apply the slope formula, m [tex]= \frac{y_2 - y_1}{x_2 - x_1}[/tex].

How to Determine the Slope of a Line?

The slope of a line (m) = change in y / change in x = (y2 - y1)/(x2 - x1).

In the slope-intercept form of an equation that represents a line, the slope is represented as "m" in y = mx + b.

The equation we can use to determine the slope (m) if we are given two points on a line is, m = (y2 - y1)/(x2 - x1).

For example, if two points, (-4,2) and (8,5) are points on the line, we can find the value of the slope (m) as:

m = (2 - 5)/(-4 - 8) = -3/-12

Slope (m) = 1/4

The value of m to use in the equation of the line would be 1/4.
