Daily profit, y, as a function of T-shirts sold, x, is
y = -10x² + 160x - 430
In order to generate $50 in daily profits, the number of T-shirts sold is determined by solving the equation
-10x² + 160x - 430 = 50
Divide through by -10.
x² - 16x + 43 = -5
x² - 16x + 48 = 0
Answer:
This quadratic equation can be solved by factorization.
Explanation:
Note that
48 = 4 x 12, and
4 + 12 = 16
Therefore
x² - 16x + 48 = (x - 4 )(x - 12 ) = 0
The solutions are
x - 4 = 0 => x = 4, and
x - 12 = 0 => x = 12
Answer:
No, they are not equivalent.
Step-by-step explanation:
Answer:
6y = 12x + 36 is x=
1
/2
y−3
15y = 45x + 60 is x=
1
/3
y+
−4
/3
Step-by-step explanation:
2x - 4 = 40 so I put 4 under both of them and crossed it out
2x = 44 I got rid of the -4 on the left side
X=22 I got rid of the 2 on the left side by dividing it and making the answer for 1 x be simple and x=22
