Hey there!
when x = 3 and y = 9
Let's first move to x and y.
Now multiply 5 by x and y(3+9).
Now we have the number 2 left, so we have to multiply 60 by 2.
Hope this helps!
Answer:
x₁ = - 5, x₂ = 5
Step-by-step explanation:
x^2 + 3 = 28
x^2 = 28 - 3
x^2 = 25
x = ± 5
x = - 5
x = 5
Answer:
The value of f(-2) is 1/2 or it can be written as 0.5.
Step-by-step explanation:
The given function is
We have to find the value of f(-2).
Substitute x=-2 in the given function to find the value of f(-2).
Therefore the value of f(-2) is 1/2 or it can be written as 0.5.
