Bryan is asked to write an inequality to represent the graph.

Mathematics

Fittoniya [83]2 years ago

7 0

The error that Bryan has done in this inequality is that he included –14 in his solution set.

<h3>How to point out the mistake made</h3>

What Bryan has to do would be to write this inequality in such a way that the variable would appear on the left.

But the symbol that he has chosen does not move in this same direction as the graph.

The -14 should not be inclusive in the graph because it is not a part of the graph solution.

He used the wrong number in this inequality.

A company has to buy computers and printers. Each computer, x, costs $585 and each printer, y, costs $385. If the company spends

Luden [163]

The company bought 9 computers and 6 printers

Solution:

Let "x" be the number of computers bought

Let "y" be the number of printers bought

cost of 1 computer = $ 585

cost of 1 printer = $ 385

The company buys a total of 15 machines

Therefore, we can frame a equation as:

number of computers bought + number of printers bought = 15

x + y = 15 ------ eqn 1

The company spends $7,575

Therefore, we can frame a equation as:

number of computers bought x cost of 1 computer + number of printers bought x cost of 1 printer = 7575

$x \times 585 + y \times 385 = 7575$

585x + 385y = 7575 ------ eqn 1

Let us solve eqn 1 and eqn 2

From eqn 1,

x = 15 - y --------- eqn 3

Substitute eqn 3 in eqn 2

585(15 - y) + 385y = 7575

8775 - 585y + 385y = 7575

-200y = 7575 - 8775

-200y = -1200

y = 6

Substitute y = 6 in eqn 3

x = 15 - 6

x = 9

Thus the company bought 9 computers and 6 printers

The shop declare a discount of 20% and later a discount of 15% after

Zolol [24]

Let, the original amount = x
First discount = x * 0.20 = 0.20x

Amount after first discount = x - 0.20x = 0.80x
Second discount = 0.80x * 0.15 = 0.12x

Amount after second discount = 0.80x - 0.12x = 0.68x
Difference would be: x-0.68x = 0.32x

So, Your Answer would be 32%

Hope this helps!

amm1812

always put the 1st number you would like to turn to scientific notation

so the 1st number here is 3

then you turn 8 into a decimal because it is the only other number that isnt 0 and then it is 3.8

you then count every number after 3 including 8 which is

then you always put 10 x whatever number you are doing but right now it is 3.8

and the answer is

10 x 3.8^7
