Answer:
no
Step-by-step explanation:
Just plug it in
-4(4) + 3(1) = 2
-16 + 3 = 2
-13 = 2
Without even solving the second equation, the answer is no because -13 does not equal 2
Answer:
x=5
Step-by-step explanation:
we can see:
20 inches= x +3x
x?
so we have
20=4x
x=20/4
x=5
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 :-
