Answer:
7 and 9
Step-by-step explanation:
7*9=63
which make 7 and 9 factors of 63
Answer:
z=kx/y
zy=kx
zy/x=kx/x ( divided both side by x. to find k)
k=zy/x
k=6×4/3(z=6,y=4,x=3)
k=24/3
k=8
so z=kx/y
z=8×5/2(replace the numbers in the place of variables,k=8,x=5,y=2)
z=40/2
z=20
Answer:
Step-by-step explanation:
The range of a function is the set of all possible values it can produce.
For example, consider the function

No matter what value we give to x, the function is always positive:
If x is 2, then the function returns x squared or 4.
If x is negative 2, then it still produces 4 since -2 times -2 is positive 4.
So the range of the function is
"all real numbers greater than or equal to zero".
Answer:
2 * sqrt(61)
Step-by-step explanation:
a = 10
b = 12
c = ?
c^2 = a^2 + b^2
c^2 = 10^2 + 12^2
c^2 = 100 + 144
c^2 = 244
c^2 = 4 * 61
sqrt(c^2) = sqrt(4) * sqrt(61)
c = 2 * sqrt(61)
