Answer:

b² - 9b + 14

Step-by-step explanation:

(b - 2) × (b - 7)

= b×b - 7b - 2b + 2×7  (Expand)

= b² - (7b + 2b) + 14  (gather like terms)

= b² - 9b + 14

The total profit for a company in February was 15% higher than it was in January. The total profit for the two months was $122,9
stepladder [879]

Answer:

The profit for January is $57,200.

Step-by-step explanation:

The total profit for the two months would be the result of adding up the profit in January plus the profit in February:

Total profits=Profit in January+Profit in February

Also, you can say that profits in January can be represented by x and you know that the profit for a company in February was 15% higher than it was in January which can be expressed as: 1.15x. Moreover, you know that the total profit for the two months was $122,980. Now, you can replace the values on the formula:

122,980=x+1.15x

Now, you can solve for x:

122,980=2.15x

x=122,980/2.15

x=57,200

According to this, the answer is that the profit for January is $57,200.

11.3 - p divided 2.8=1.5
raketka [301]

<u><em>p=27.44</em></u>

11.3-\frac{p}{2.8}=1.5

First you subtract by eleven point three (11.3) from both sides of equation form.

And it gave us ⇒ 11.3-\frac{p}{2.8}-11.3=1.5-11.3.

Then you simplify by equation.

And it gave us ⇒ -\frac{p}{2.8}=-9.8.

Next, you multiply by two decimal eight (2.8) from both sides of equation form.

And it gave us ⇒ 2.8(-\frac{p}{2.8)}=2.8(-9.8).

And then simplify by equation.

-p=-27.44.

Next, you divide by negative one (-1) from both sides of equation form.

And it gave us, \frac{-p}{-1}=\frac{-27.44}{-1}.

And finally simplify by equation form.

And it gave us the final answer is p=27.44.

Hope this helps!

And thank you for posting you for posting your question at here on brainly, and have a great day. -Charlie

Write the equation of the line in fully simplified slope-intercept form
Gennadij [26K]

Answer:

y=1/2x+8

Step-by-step explanation:

grab 2 points in this case (4,10) and (0,8)

use rise over run formula so it rises 2 and goes over 4

so 2/4 then simplify and you get 1/2

and the y intercept is 8 because thats when the slope touches the y line

so using the equation y=mx+b when m is slope and b is y interecpt

the answer should be y=1/2x+8
