This year, a company produced 8 percent more items than last year. If the company produced 243 items this year, how many items d

Ilya [14]

Answer:

Last year company produce 225 items

Step-by-step explanation:

let the number of items produced last year be x

Here we are asked to find the percent increase in the production of the items from last year

The production for the last year = x

The production for the current year = 243

Total increased production =243-x

Hence percentage calculation = $\frac{\increase \in \sale}{\last \year \sale} \times 100$ %

Increased percentage = $\frac{243-x}{x} \times 100$ %

Percentage increased = 8 %

Hence

$\frac{243-x}{x} \times 100 = 8$

${243-x}\times 100 = 8 \times x$

$24300-100x = 8x$

$24300=100x+8x$

$24300=108x$

$x= \frac{24300}{108}$

x=225

Hence Last year production was 225 items

What is the slope of the line that passes through the points (1,7) and (-4,-8)?

julia-pushkina [17]

Answer:

The slope of the line that passes through the points (1,7) and (-4,-8) is 3.

Step-by-step explanation:

The equation of a line has the following format.

$y = ax + b$

In which a is the slope.

Passes through the point (1,7)

When $x = 1, y = 7$

$y = ax + b$

$7 = a + b$

Passes through the point (-4, -8)

When $x = -4, y = -8$

$y = ax + b$

$-8 = -4a + b$

We have to solve the following system

$a + b = 7$

$-4a + b = -8$

We want to find a.

From the first equation

$b = 7 - a$

Replacing in the second equation

$-4a + b = -8$

$-4a + 7 - a = -8$

$-5a = -15$

$5a = 15$

$a = \frac{15}{5}$

$a = 3$

The slope of the line that passes through the points (1,7) and (-4,-8) is 3.
