Question 1 Simplify the following expression: (5x2 + 3x + 4) − (2x2 − 6x + 3). If the final answer is written in the form Ax2 + Bx + C, what is the value of B?
Solution:
5x^2 + 3x + 4 - 2x^2 + 6x - 3 = 3x^2 + 9x + 1
Then, B = 9 Hope this helped=)

To make concrete it take 8 parts crushed gravel, 7 parts water and 5 parts cement mix. A worker needs to make 220 kg of concrete
Romashka-Z-Leto [24]

A complete load of concrete = 8 parts gravel + 7 parts water + 5 parts cement.

Total number of parts in every load = 8 + 7 + 5 = 20 parts

If total load = 220 kg, then       20 parts = 220 kg

Divide each side by  20 :             1 part = 11 kg

gravel   = 8 parts = 8 x 11 kg = <em>88 kg</em>
water    = 7 parts = 7 x 11 kg = <em>77 kg</em>
cement = 5 parts = 5 x 11 kg = <em>55 kg</em>

<u>Check:</u>    88 + 77 + 55 = 220         yay !

A semiconductor manufacturing company employs 1,000 people. The average weekly salary of each employee is $750.
Novay_Z [31]

Answer:

Graph A is the correct choice.

Step-by-step explanation:

Let x be the number of weeks.

We have been given that a  semiconductor manufacturing company employs 1,000 people. The average weekly salary of each employee is $750.

Let us find the weekly salary for 1000 employees by multiplying 1000 by $750.

\text{The weekly salary for 1,000 employees}=1,000\times \$750

\text{The weekly salary for 1,000 employees}=\$750,000

Let us find amount of salaries after 52 weeks as 1 year equals 52 weeks.

\text{The amount of salaries after 52 weeks for 1,000 employees}=52*\$750,000

\text{The amount of salaries after 52 weeks for 1,000 employees}=\$39000000  

Since at week 0, the salaries for 1000 employees will be also 0, so point (0,0) will be on the line of our graph.

Now let see which of our given graphs has point (0,0) and (52,39000000).

We can see that graph A has y-value 39 million on x equals 52, therefore, Graph A is the correct choice.
