Solve the following system:
3x + 2y = 7
-4.5x - 3y = -10.5
Answer:
infinitely many solutions
Step-by-step explanation:
The system of equations :
3x + 2y = 7-4.5x - 3y = -10.5Multiplying Equation 1 times 3 and Equation 2 times 2 :
9x + 6y = 21-9x - 6y = -21Putting the equations in standard form after simplifying :
6y = -9x + 21 ⇒ y = -1.5x + 3.5-6y = 9x - 21 ⇒ y = -1.5x + 3.5As both equations are the same, the system will have infinitely many solutions.

The access code for a company's security system consists of four digits. Each digit can be 0 through 9. The company want to issue a different security code to each of its 200 employees. The company also has to re-issue new codes to each employee every month for security purposes. How many access codes are possible if..
Each digit can be used only once and NOT repeated?
Please help someone :(
Answer:
2 codes are possible
Step-by-step explanation:
4 6
2571
0389
There are only 10 digits and you can only use the digits onces so the answer would be 2 codes are possible.
The number of possible codes will be 5,040.
How to get the possible codes?If each digit can be used only once, then the number of possible access codes is calculated as follows:
The first digit can be any of the 10 digits (0 through 9).
The second digit can be any of the remaining 9 digits (since one digit has already been used).
The third digit can be any of the remaining 8 digits.
The fourth digit can be any of the remaining 7 digits.
Therefore, the total number of possible access codes is:
10 x 9 x 8 x 7 = 5,040
So, there are 5,040 possible access codes if each digit can be used only once and not repeated.
Since there are 200 employees, the company has enough unique codes for each employee for 25 months. After that, the codes will have to be repeated, which may compromise the security of the system.

You invest $500 into an account that collects 1% interest each month. If you add an additional $50 each week, what will the balance of the account be after 5 months?
Answer:
$1555.91
Step-by-step explanation:
First Month:
You start out with $500.
You add $200 in the first month, and have 700.
Multiply 700 by 1.01, to add the interest and you get 707.
Second Month:
707 + 200 = 907
907 x 1.01 = 916.07
Third Month:
916.07 + 200 = 1116.07
1116.07 x 1.01 = 1127.2307
Fourth Month:
1127.2307 + 200 = 1327.2307
1327.2307 x 1.01 = 1340.503007 (round to .50)
Fifth Month:
1340.50 + 200 = 1540.50
1540.50 x 1.01 = 1555.905
Round to 1555.905 1555.91, and there's your answer. Hope this helps!

Consider the division of 8y2 – 12y + 4 by 4y.
What are the values of a and b?
a = 2y and b = 3
a = and b = –3y
a = 2y and b = –3
a = and b = 3y
Notice that the dividend [tex]8y^2-12y+4[/tex] has tree terms with [tex]a=8y^2[/tex], [tex]b=-12y[/tex], c [tex]c=4[/tex]
Now, to divided our dividend [tex]8y^2-12y+4[/tex] by the monomial (single term) [tex]4y[/tex], the easiest thing to do is divide each term of the dividend by the monomial:
[tex]8y^2-12y+4[/tex] ÷ [tex]4y[/tex] = [tex]\frac{8y^2-12y+4}{4y}=\frac{8y^2}{4y}-\frac{12y}{4y}+\frac{4}{4y}=2y-3+\frac{1}{y}[/tex]
After performing the division we get that now [tex]a=2y[/tex] and [tex]b=-3[/tex]
We can conclude that the correct answer is a = 2y and b = –3

Answer:
5.32 inches
Step-by-step explanation:
It is given that 1 inch represents 50 feet, or 1 in = 50 feet.
The actual dome is 266 feet. To find the amount of inches, divide 266 with 50:
266 total feet/50 feet per inch = 5.32 inches.
The scale model in inches, therefore, would be 5.32 inches.

angle p?°
Answer:
A) 75°
Step-by-step explanation:
It is the property of a polygon that the sum of the external angles is equal to 360°.
===============================================================
Solving :
⇒ p + 55 + 30 + 75 + 55 + 70 = 360
⇒ p + 85 + 130 + 70 = 360
⇒ p + 285 = 360
⇒ p = 360 - 285
⇒ ∠p = 75°
Answer :
A) 75°
because the property of polygon is equal to 360° the sum of external angles.
