Step-by-step explanation:
-7,-3,1,5,... is a arithmetic sequence.
Arithmetic sequences have a common difference. That is, it is going up by 4 each time.
When you see arithmetic sequence, you should think linear equation.
The point-slope form of a line is
.
m is the common difference, the slope.
Any they are using the point at x=1 in the point slope form. So they are using (1,-7).
So let's put this into our point-slope form:


Subtract 7 on both sides:

So your answer is

The tax is found by mult. the total purchase by 1.07:
1.07(3)($0.99) = $3.18 (rounded up to the nearest cent)
The possible length of segment AB is 27 < AB < 81
From the question, we have
In triangle ABC
AC = 27
CB = 54
Using Pythagoras theorem,
AC² = AB² + CB²
54² = AB² + 27²
AB = 47
The possible length of segment AB is 27 < AB < 81
Multiplication:
To determine the sum of two or more numbers, mathematicians multiply the numbers. It is a basic mathematical procedure that is widely used in daily life. Multiplication is used when we need to mix groups of like sizes. Multiplication is a representation of the underlying idea of adding the same number repeatedly. The outcome of multiplying two or more numbers is referred to as the product of those numbers, and the factors are the quantities that are multiplied. Multiplying the numbers makes it simpler to add the same number repeatedly.
