Answer:

The equation is;

2y = 3x + 6

Step-by-step explanation:

We start by calculating the slope of the line

m= y2-y1/x2-x1

m = (6+3)/(2+ 4) = 9/6 = 3/2

The point slope form would be;

y-y1 = m(x-x1)

Let us use the point (-4,-3)

Thus, we have

y + 3 = 3/2(x+ 4)

2y + 6 = 3x + 12

2y = 3x + 12-6

2y = 3x + 6

A store owner had 225 suits. At the end of a sale he had sold 4/5 of them. How many suits were left?

AleksAgata [21]

The store owner sold 4/5 of the suitces. That means 1/5 of the suitcases are left. Multiple 225 to 1/5

$225* \frac{1}{5} = \frac{225}{1}* \frac{1}{5} = \frac{225*1}{1*5} = \frac{225}{5} =45$

There are 45 suitcases left

Answer: 1) $9000

2) $5340

3)59.3%

Step-by-step explanation:

Since we have given that

Worth of life insurance = $60000

Amount of premium = $900

After the end of 10 years,

1) Amount of premium Tom had paid is given by

$10\times 900=\$9000$

2) At the end of 10 years ,

The cash value of his policy by using the table is given by

$\frac{89}{1000}\times 60000\\\\=\$5340$

3) At the end of 10 years ,

Ratio of cash value to premiums paid be

$5340:9000\\\\=\frac{5340}{9000}\times 100\\\\=59.3\%$
