The y intercept is not (360,0) or answer C :)
It is (0,360) lol
Answer:
the common ratio is 5 please do you get it
Answer:
x = 8
x = 7
Step-by-step explanation:
Solving x2-15x+56 = 0 by the Quadratic Formula .
According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 1
B = -15
C = 56
Accordingly, B2 - 4AC =
225 - 224 =
1
Applying the quadratic formula :
15 ± √ 1
x = —————
2
So now we are looking at:
x = ( 15 ± 1) / 2
Two real solutions:
x =(15+√1)/2= 8.000
or:
x =(15-√1)/2= 7.000
I would say around 8-10 ounces
Charlie's solution is incorrect. He did step 2 incorrectly. Because the equation is 5x = 30, he needs to divide by 5 instead of subtract 5 from both sides.
If this was done correctly, it would like like this:
Step 1: 5x = 30
Step 2: x = 30/5
Step 3: x = 6
This equation will only have one solution, x = 6.
