Answer:
-2
Step-by-step explanation:
Put the given values of x and y in the equation, and solve for "a".
-40 = a(1 +3)(1 -2)(1 -6) = 20a
-40/20 = a = -2
The value of "a" is -2.
Answer: a. n+16
b. n-22

Answer:
Step-by-step explanation:
The quadratic formula helps us find the roots of a quadratic equation. The equation is:
where
The discriminant is just the part under the square root. This helps tell us if there are two, one, or zero real solutions.
The discriminant is:
We are given the quadratic:
Therefore, a is 9, b is -8, and c is -2.
Solve the exponent.
Multiply 4, 9, and -2.
The discriminant is 136. Since it is a non-zero, positive number, this quadratic has 2 real solutions/zeroes/roots.
