Answer:
A= 320 and B = 280
Step-by-step explanation:
- Amount of sodium from first material = 0.15*A
- Amount of sodium from second material = 0.3*B
Now, if we combine the two chemicals to get a new chemical, which is 22% sodium, then the total amount of combined sodium is amount of sodium from both sources
<=> 0.15A + 0.3B = 0.22*(A+B)
<=> 0.07A - 0.08B = 0 (1)
- But we have a second equation, because we know that A + B = 600 (2)
Solve the system of two equations, (1) and (2), we have:
A= 320 and B = 280
Answer:
see image...
start with Graphing Form: y = a(x-h)²+ k
knowing that h is the x value (negative of it) of the vertex , and k is the y value of the vertex
Graphing Form Equation: y = a(x+3)²+32
you are also given that when the x value is 5 the y value has to be 0
0 = a(4)^2 + 32
a has to be - 1/2
