Answer:

A. Column: boy, girl; Row: arrive by car, arrive by bus

Step-by-step explanation:

We are given that,

Lashaun created a table comparing the number of students arriving by car to the number of students arriving by bus.

He compared the number of boys and girls arriving by what means of transport.

Thus, we have that,

The table made by Lashaun consists of:

Number of boys

Number of girls

Students arriving by Car

Students arriving by bus

Thus, the column headings of the table could be 'Boys, Girls' and the row headings could be 'Arriving by Car, Arriving by bus'.

Hence, option A is correct.

A. only asked to compare the number of students who arrive to school by car and bus.

Chris Shopper received a $1,000 discount loan to purchase a washer and dryer. The loan was offered at 12% for 120 days. What are the proceeds?

The proceeds are $959.96

What is compound interest?Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.

Given that, Chris Shopper received a $1,000 discount loan to purchase a washer and dryer. The loan was offered at 12% for 120 days.

Principal = $1000

Interest = 12%

Time = 120 days = 0.33 years

n = number of times the interest rate is compounded in one year

⇒ n = 12

Compound interest = P(1+r/100)ⁿ

= 1000(1+12/12×100)³⁹⁶/₁₀₀

= $1040.04

Interest = 1040.04 - 1000

= $40.04

And the Proceeds are = Principal - Interest

= 1000 - 40.04

= $959.96

7x−5=4y−6 x determine the intercepts of the line

Answer:

see explanation

Step-by-step explanation:

to find the intercepts, that is where the line crosses the x and y axes

• let x = 0, in the equation for the y-intercept

• let y = 0, in the equation for x-intercept

x = 0

⇒ - 5 = 4y ( divide both sides by 4 )

y = - ← y- intercept

y = 0

7x - 5 = - 6x ( add 6x to both sides )

13x - 5 = 0 ( add 5 to both sides )

13x = 5 ( divide both sides by 13 )

x = ← x- intercept

To find the x-intercept, substitute in
