The vertex is x = 3 and the maximum is at (3, 23)
1.
The <u>new system</u> of equivalent equations are 4x + 6y = 8 and 12x + 3y = 1
To get an equivalent equation, we multiply the original equation by a constant and replace it with the new equation.
So, 2x + 3y = 4 (1)
12x + 3y = 1 (2)
We multiply equation (1) by 2
So, 2x + 3y = 4 (1) × 2
⇒4x + 6y = 8 (3)
Replacing (1) by (3), we have
4x + 6y = 8 (3)
12x + 3y = 1 (2)
So, the <u>new system</u> of equivalent equations are 4x + 6y = 8 and 12x + 3y = 1.
2.
The <u>new system</u> of equivalent equations are 3x - 21y = 24 and 5x + 4y = 20
To get an equivalent equation, we multiply the original equation by a constant and replace it with the new equation.
So,
x - 7y = 8 (1)
5x + 4y = 20 (2)
We multiply equation (1) by 3, we have
So, x - 7y = 8 (1) × 3
⇒3x - 21y = 24 (3)
Replacing (1) by (3), we have
3x - 21y = 24 (3)
5x + 4y = 20 (2)
So, the <u>new system</u> of equivalent equations are 3x - 21y = 24 and 5x + 4y = 20.

Answer:
d. 22
Step-by-step explanation:
It gives you the perimeter which is 49. You subtract the given sides from 49. That leaves you with 22.
49-9-18=22
Answer:
4.44
Step-by-step explanation:
The tangent of B is the relation of the opposite cathetus to the lying cathetus
tg B= AC/CB= 40/9= 4.44
Answer:
Step-by-step explanation:
We are given that TechWiz sold MP3 player and DVD player and makes profit.
We have to find an expression for the combined total profit (in dollars) what TechWiz made from MP3 and DVD player last week.
We are given that
Let number of MP3 players sold in last week=x
Number of DVD players sold in last week =y
When TechWiz sold combined total MP3 and DVD players=153
Profit on one MP3 player=$35
Profit on one DVD player=$18
Total profit on x MP3 players= 35 x
Total profit on y DVD players= 18 y
Therefore, the combined total profit in last week
The expression for the combined total profit what TechWiz made from Mp3 players and DVD palyers
