Answer: 4x-16

Step-by-step explanation:

Answer:

y=4x+5

Step-by-step explanation:

x= the number of hours

y= total number of money

4x means each hour = 4 dollars

5 = the rent of the shoes

Therefore, y = 4x + 5

Answer:

y=-3/5x-5

the slope would be -3/5

Answer:

450 words in 10 minutes

Step-by-step explanation:

To set this up you need to put it like this:

[tex]\frac{180}{4}[/tex] = [tex]\frac{x}{10}[/tex]

From here, you need to cross multiply, which will get you to: 180(10) = 4x

Multiply 180 and 10: 1,800

The equation will now be: 1,800 = 4x

Now, divide both sides by 4:   450 = x

The required word that tara would type in 10 minutes is 450 words.

Given that,
Tara can type 180 words in 4 minutes. At this rate,
To determine how many words would you expect her to type in 10 minutes.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The rate of typing = 180 / 4 = 45 word per minute
Now a number of words typed in 10 minutes,

= 10 * 45
= 450 words per minute,

Thus, the required word that tara would type in 10 minutes is 450 words.

Step-by-step explanation:

I plugged in the points (-1,4) and (4,-4) into the formula y2-y1 divided by x2-x1

Answer:

Slope = -2

Step-by-step explanation:

x1   y1     x2   y2

(-1 , 9)     (2 , 3)

Slope = y2 - y1

             x2 - x1

3 - 9  = -6  

2 -(-1) =   3

                      = -2

The slope between the two points is -2.

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,

The  slope is given as,

m = (d - b) / (c - a)

Where (a, b) and (c, d) are the two points.

Now,

(-1, 9) = (a, b) and (2, 3) = (c, d)

m = (3 - 9) / (2 + 1)

m = -6 / 3

m = -2

Thus,

The slope is -2.

There is no slope so there is a slope of 0

The y-intercept is the origin so also 0 so the equation will be y=0

Answer:

It will take 5.3 years to reach $39,500

Step-by-step explanation:

Compound Interest

It occurs when the interest is reinvested rather than paying it out.

Interest in the next compound period is then earned on the principal sum plus the previously accumulated interest.

The formula is:

[tex]\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}[/tex]

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

We are required to find the time needed to convert the principal P into a given final amount.

Solving the above equation for t, we get:

[tex]\displaystyle t=\frac{log(A/P)}{n\cdot log\left(1+r/n\right)}[/tex]

Anne invested P=$28,000 in an account at r=6.5%=0.065 compounded daily. There are 360 days in a year, so n=360. The final amount A=$39,500.

Substituting into the formula:

[tex]\displaystyle t=\frac{log(39,500/28,000)}{360\cdot log\left(1+0.065/360\right)}[/tex]

t=5.3 years

It will take 5.3 years to reach $39,500

-5y = 40

y = -8

Answer:

-8

Step-by-step explanation:

replace X with 5

subtract 5 from both sides of the equation:

-5y = 40

divide by - 5

y = -8

Answer:

Step-by-step explanation:

If we're going by estimation, then you can do 11 and 7 hours, meaning that she would make 77 for the 7 hours but the exact answer would be a bit less than the estimation

10.9 times 6.75 is 73.58 roughly. so 3 dollars and 42 cents off

Answer:

1. She could use 7 hours and 11 dollars per hour.

2. $77 (7x11)

3 I'd say my estimate is a little more than the exact amount because I did 6.75 (6.75 because 45 minutes is 75% of a hour) x 10.90 and got 73.575.
