Answer:
1 1/12 cups
Step-by-step explanation:
2 1/4 = 9/4
9/4 - 1/3
27/12 - 4/12
23/12 = 1 1/12
Solve the equation using the quadratic formula ⇨ x² + 11x + 9 = 0
All equations of the form can be solved using the quadratic formula: . The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.
This equation is in standard form: ax² + bx + c = 0. Substitute 1 for a, 11 for b and 9 for c in the quadratic formula .
Square 11.
Multiply -4 times 9.
Add 121 to -36.
Now solve the equation when ± is plus. Add -11 to √85.
Now solve the equation when ± is minus. Subtract √85 from -11.
The equation is now solved. The solution set is :-
Answer:
46
Step-by-step explanation:
You need just substitute values of x and y, and calculate.
24x - 13y = 24*3 - 13*2 = 72 - 26 = 46
1 is 8 weeks because 8 times 25 is 200. #2 is 1.75 minus 10
Which is 8.25 divided that by .65 is 12.69
Answer:
A
Step-by-step explanation:
The parabola opens to the left, so this eliminates C and D.
Also, the vertex is at (-17, 2), and out of A and B, the only parabola with this vertex is A.
