Answer:
x=-5 x=-4
Step-by-step explanation:
y=x^2 + 9x + 20
We need to factor the equation
What 2 numbers multiply to 20 and add to 9
4*5 = 20
4+5 =9
y=(x+5) (x+4)
To find the zero's we set the equation equal to zero
0= (x+5) (x+4)
Using the zero product property
x+5 = 0 x+4=0
x=-5 x=-4
A function is a relationship that each input (element of the domain) is paired with exactly one output (element in the range).
In function notation, f(x), the “x” is the input and the entire “f(x)” represents an output.
That means the last two options are wrong. They’re purposely switched up in what they say.
The correct answer is the second one, because that one is saying “each input will be paired with exactly one output.”
Answer:
h = b(√3)/2
Step-by-step explanation:
The ratio of base to height of an equilateral triangle is ...
... b/h = 2/√3
Multiplying both sides of the equation by (√3)h/2, we get
.. h = b(√3)/2 . . . . . . your equation with h as the subject
