Answer:
Step-by-step explanation:
So we want to make x the subject of the formula:
First, distribute the left side:
Combine all the terms with x with it on one side. To do this, first subtract bx from both sides. The right side cancels:
Remove the -ab from the left. Add ab to both sides. The left side cancels:
Now, distribute out the x from the left side:
Divide both sides by (a-b). The left side cancels:
Therefore:
Answer:
-20/33
Step-by-step explanation:
y2 - y1 / x2 - x1
1/6 - (-1/4) / -5/16 - 3/8
5/12 / -11/16
= -20/33
Step-by-step explanation:
The parent function of the functions of the form f(x)=√x−a+b is f(x)=√x . Note that the domain of f(x)=√x is x≥0 and the range is y≥0 . The graph of f(x)=√x−a+b can be obtained by translating the graph of f(x)=√x to a units to the right and then b units up.

Answer:
13
Step-by-step explanation:
where n is the number of terms, a1 is the first term and an is the last term. The sum of the first n terms of an arithmetic sequence is called an arithmetic series . Example 1: Find the sum of the first 20 terms of the arithmetic series if a1=5 and a20=62 .An arithmetic sequence is a sequence where the difference between any two consecutive terms is a constant. ... As with any recursive formula, the initial term of the sequence must be given. An explicit formula for an arithmetic sequence with common difference d is given by an=a1+d(n−1) a n = a 1 + d ( n − 1 ) .
To solve this, you would do:
x + 75% * x = 35
7/4 * x = 35
x = 20
