B 49 is the correct answer
Answer:
A
Step-by-step explanation:
The zeroes of the function are the x values when f(x) = 0 so we can write:
0 = x² + x - 30
0 = (x + 6)(x - 5) (To factor this we need to find 2 numbers that have a sum of 1 and a product of -30; these numbers are 6 and -5)
x + 6 = 0 or x - 5 = 0 (Use Zero Product Property)
x = -6, 5
Answer:
The coefficient of variable term y is -1
Step-by-step explanation:
We have an expression given in the question that is:
6 - y + 3
We have to find the coefficient of the variable term.
In mathematics, variable can be defined as any term which is to be measured. For example in the given expression, y is the variable because its value is unknown yet and it has to be measured.
Coefficients are the number the multiply the variable
For example
In 2x, x is the variable and 2 is the coefficient.
Now in the given expression, we have
6 - y + 3
or
6 + (-1)(y) + 3
So considering (-1)(y), the variable is y while its coefficent is -1
