Subtract 7x on both sides of the equal sign (it'll cancel out) then -3=-3 which makes a true statement.
The given function is
f(x)= 0.2 x²
Since f(x) will be defined for all real values of x.
So, Domain of f(x) will be ( x| x is a real number.)→This is set builder notation.
Finding the inverse of f(x):
y = 0.2 x²
→ x²= 5 y
→x =
→ → Inverse of f(x)
Replacing x by y and y by x,we get inverse of the given function
y =
→ →Domain x ≥ 0, x∈[0,∞]
Graph of function and its inverse are shown below.
Answer:

Step-by-step explanation:
we know that
If triangles EFG and QRS are similar
then
the scale factor is equal to the measure of the smallest side of triangle QRS divided by the smallest side of triangle EFG
so
Let
x-------> the smallest side of triangle QRS
y-------> the smallest side of triangle EFG
z-------> the scale factor
we have

substitute the values


Find the length of the longest side of QRS
The length of the longest side of QRS is equal to multiply the scale factor by the length of the longest side of EFG
so

Answer:
1/12
Step-by-step explanation:
The probability of landing heads is 1/2, the probability of rolling a 3 is 1/6. Multiply them to get the answer.
Hope this helped!
X=7, y=6. that’s your answer!
