Answer:
x+10/
Step-by-step explanation:
Quotient of 4 =divide by 4
a number increased by 10= x+10
Answer:
B
Step-by-step explanation:
cos(ax) reduces the period by a. So y will have a period of (2*pi)/4=pi/2
Answer:
Answer:
Domain is
All real number except at x=0
Step-by-step explanation:
We are given
Firstly, we will find (fog)(x)
now, we can plug back g(x)
Domain:
we know that domain is all possible values of x for which any function is defined
and we know that denominator of any function can not be zero
so, we set denominator =0
so, function will be defined for all values of x except at x=0
So, domain will be
All real number except at x=0

You’re basically doing 12×9-3×4×2 and then you get 84!
Your answer is the last option, 7 or 12.
We can write this question as an equation, if we call the number ‘x’:
(x - 9)² = x - 3
Then we can expand the bracket and solve for x:
x² - 18x + 81 = x - 3
x² - 19x + 84 = 0
(x - 7)(x - 12) = 0
x = 7 or x = 12
The factorisation is a bit difficult so you could also use the quadratic formula to get to the same answer.
I hope this helps! Let me know if you have any questions :)
