Answer:
x = 5 - a
Step-by-step explanation:
Given
6x + a = 5(x + 1) ← distribute
6x + a = 5x + 5 ( subtract 5x from both sides )
x + a = 5 ( subtract a from both sides )
x = 5 - a

Answer:

Step-by-step explanation:
This problem can be answered by using proportions based on similar triangles.
Notice that a person and its shadow on the ground form a right angle (therefore they can be considered the two "legs" of a right angle triangle)
The same runs for the tree and its shadow.
Since the inclination of the rays of the sun are the same at the same time for both objects (the boy and the tree), their hypothenuses form the same angles with the ground and therefore belong to similar triangles.
We can create the following proportion to solve for the shadow of the tree (ST) using the information provided: the height of the boy (HB), the shadow of the boy (SB), and the height of the tree (HT)

Answer:
The inverse of x² +1 is:

Step-by-step explanation:
Given
y = x² + 1, x>0
We know that A function g is the inverse of a function f if for y = f(x), x = g(y)
y = x² +1
Replace x with y
x = y² + 1
solve for y
y² = x - 1
Taking square root

Thus, the inverse of x² +1 is:
