WILL SOMEONE HELP ME ANSWER THIS PLEASE!!!!
Luca and William are playing a video game and they have scored a total of 20,000 points. Luca scored 4,000 more points than William. If you let l= the number of points that Luca scored, and w= the number of points that William scored, then the problem can be represented by the system:
l+w=20,000 and l=w+4,000
Graph the system. How many points did each boy score?
My possible answers are:
a. William = 8,000 and Luca = 12,000
b. William = 12,000 and Luca = 8,000
d. William = 4,000 and Luca = 16,000
l+w=20000
l=w+4000
w+4000+w=20000
2w+4000=20000
2w=16000
w=8000
l = 8000 +4000 = 12000
William scored 8000, Luca scored 12000

Which options show the correct steps for finding the x-coordinate of the vertex in the equation y=x^2+6x+8?
Ajay analyzed two companies and has formulated tables to model each company’s growth, where x represents the age of the companies in years and y represents growth in terms of number of employees. Company 1 Company 2
Table 1 Table 2
x l y x l y
0 l 0 0 l 1
1 l 6 1 l 6
2 l 12 2 l 36
3 l 18 2 l 216
4 l 24 4 l 1,296
If the number of employees is an indicator of a successful business, in which company should Ajay invest? company 1 because it is adding six employees each year while company 2 is multiplying its number of employees by six each year company 1 because it is multiplying its number of employees by six each year while company 2 is adding six employees each year company 2 because it is adding six employees each year while c
Answer:
Company 2 because it is gaining six times the number of employees, while Company 1 is only adding 6 employees every year.
Step-by-step explanation:
Looking at the table, the number of employees in Company 1 goes up by 6 employees per year.
The number of employees in Company 2 is multiplied by 6 every year; this means they gain more employees after the first year than Company 2 does (they go from 6 to 36, which is a gain of 30, while Company 1 goes from 6 to 12, a gain of 6).
If we are looking strictly at the number of employees, Company 2 is the better choice.
Answer:
company 2 is multiplying

A photo that is 4 in wide and 6 in high is enlarged to a poster that is 3ft wide and 4 1/2 ft high what is the ratio of the width of the photo to the width of the poster
Answer:
Required ratio in the simplest form = 1 : 9
Step-by-step explanation:
Width of photo = 4 inches
Height of the photo = 6 inches
Width of the poster = 3 feet
Now, 1 feet = 12 inches
So, Width of the poster = 3 × 12 = 36 inches
Height of the poster = 4.5 feet
= 54 inches
We need to find the ratio of the width of the photo to the width of the poster
⇒ Required Ratio = 4 : 36
⇒ Required ratio in the simplest form = 1 : 9

The equivalent expression is a^m − n
What are properties of exponents?The properties of exponents are mentioned below.
Law of Product: a^m × a^n = a^m+nLaw of Quotient: a^m/a^n = a^m-nLaw of Zero Exponent: a^0 = 1Law of Negative Exponent: a^-m = 1/a^mLaw of Power of a Power: (a^m)^n = a^mnLaw of Power of a Product: (ab)^m = a^m*b^mLaw of Power of a Quotient: (a/b)^m = a^m/b^mGiven expression:
am ÷ an
Now, using the law of exponents we have
a^m ÷ a^n
=a^(m-n)
Hence, the equivalent expression is a^m − n
