The profit is 10,000 dollars if the profit she sells is 60 kilograms
Answer:
The Y intercept doesn't exist, and the slope is undefined
Step-by-step explanation:
The graph provided for us is a vertical line. x= 7
this means the line will go up and down forever without a slant because x will always equal 7.
Ex:
X | Y
7 | -3
7 | -2
7 | -1
7 | 0
7 | 1
7 | 2
7 | 3
Answer:
x = $3.50; y = $2.25
Step-by-step explanation:
First, come up with your two equations where x= price of walnuts and y= price of chocolate chips: 8x + 4y = 37 and 3x + 2y = 15. Solve the first equation.
3x + 2y = 15
3x = 15 - 2y
x = (15 - 2y)/3
Plug in the answer to your second equation.
8(15 - 2y)/3 + 4y = 37
(120 - 16y)/3 + 4y = 37
120 - 16y + 12y = 111
120 - 4y = 111
-4y = -9
y = 2.25
Plug in your answer to find <em>x.</em>
3x + 2(2.25) = 15
3x + 4.5 = 15
3x = 10.5
x = 3.5
Check your equation.
1) 3(3.5) + 2(2.25) = 15
10.5 + 4.5 = 15
15 = 15
2) 8(3.5) + 4(2.25) = 37
28 + 9 = 37
37 = 37
You can use the <u>determinant</u><u> (square root)</u> of a quadratic equation to determine the number and type of solutions of the equation.
> 0 → 2 real solutions
- if is a perfect square, then rational sol'ns
- if is not a perfect square, then irrational sol'ns
= 0 → 1 real solution (double root)
< 0 → 2 imaginary(complex) solutions
