Write an equation in slope-intercept form of the line that passes through the
points (-5, -3) and (1, 9).

Answers

Answer 1

Answer:

[tex]\boxed{\sf{y=2x+7}}[/tex]

Step-by-step explanation:

Use a slope formula and slope-intercept formula.

Slope-intercept formula:

[tex]\sf{y=mx+b}[/tex]

The m represents the slope.

The b represents the y-intercept.

Slope formula:

[tex]\sf{\dfrac{y_2-y_1}{x_2-x_1}}[/tex]

[tex]\sf{y_2=9}\\\\\sf{y_1=(-3)}\\\\\sf{x_2=1}\\\\\sf{x_1=(-5)}[/tex]

Rewrite the problem down.

[tex]\sf{\dfrac{9-(-3)}{1-(-5)}=\dfrac{9+3=12}{1+5=6}=\dfrac{12}{6}=2 }[/tex]

The slope is 2.The y-intercept is 7.

y=2x+7

Therefore, the correct answer is y=2x+7.

Jessica’s adjusted balance for October with 3 purchases and 2 payments comes to be $1136.71.

What is the adjusted balance method?

In this method payment done by the borrower in between the month is adjusted in the final balance on which interest is to be levied.

Details of transactions for the month of October are given as:

Date     Transaction/amount            Details

10/1             $1,240.55                   beginning balance

10/2            $36.43                            purchase

10/22          $25.00                            purchase

Total balance at the end of October

= 1240.55+36.43-75-131.79+41.52-25

Total balance at the end of October =$1136.71

Therefore, Jessica’s adjusted balance for October is $1136.71.

Answers

Answer:

Pu.s - pc = 0

Pu.s -pc ≠ 0

(Answer D)

Step-by-step explanation:

Kahn

The appropriate set of hypotheses for Alex's significance test is option D.

What is Hypothesis Testing?

Hypothesis testing is the testing of the relationship between two variables for something we needed to test.

There is null hypothesis and alternate hypothesis.

Null hypothesis, H₀ is the statement we need to test.

Alternate hypothesis, H₁, is true if null hypothesis is false.

Here, given that,

Alex wonders if the same proportion of people are left-handed in the United States and Canada.

He wants to obtain a random sample of people from each country to test if there is a significant difference between the proportion of left-handed people in each country.

H₀ : there is no significant difference

H₁ : there is a significant difference

So the correct option is,

H₀ : p(U.S) - p(C) = 0

H₁ : p(U.S) - p(C) ≠ 0

Hence the correct option is D.

A symmetric data distribution is depicted on a box plot when the median is in the middle of the rectangular box, and the whiskers are of almost the same length at both sides of the box. Such data distribution is said to be normally distributed.

A normally distributed data distribution is symmetric.

Interquartile range is a measure of variability in a box plot, which is the range of the rectangular box.

If it’s a negative number like (-13, -9) go left 13 from 0 and then go down 9 and draw a little cross again.

Answers

An equation is formed of two equal expressions. The amount that is left with Ian to spend is 855,764 won.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The total expenses that Ian has to do are the cost of an extended travel pass, cost of plane tickets, cost of food, and cost of his hotel room. Therefore, the total cost can be written as,

Total Cost =  Cost of an extended travel pass + Cost of plane tickets + Cost of food + Cost of his hotel room

Total Cost = 85,210 won + 725,726 won + 203,396 won + 322,800 won

                  = 1,337,132 won

The budget for the entire trip of Ian is 2,192,896 won, while his total expenditure is 1,337,132 won, therefore, the amount that will be left for spending by Ian can be written as,

Amount left for Spending  = Total Budget - Total Cost

                                            = 2,192,896 won - 1,337,132 won

                                            = 855,764 won

Thus, the amount left with Ian to spend is 855,764 won.
