Answer:
Step-by-step explanation:
To complete the square you need to add to both sides. (Parenthesis around b/2)
b = 10
b/2 = 5
(b/2)^2 = 25
+10x + 16 = 0
subtract 16 to both sides
+ 10x = -16
add 25 to both sides
+10x + 25 = 9
Perfect Square Trinomial Factoring
= 9
The answer is 92 estimates 90

<h3>
What are decimal numbers?</h3>
- The decimal numeral system is the most widely used system for representing both integer and non-integer numbers.
- It is the Hindu-Arabic numeral system's extension to non-integer numbers.
- Decimal notation is the method of representing numbers in the decimal system.
- Decimal refers to the base-10 number system, which is probably the most widely used number system.
- There are ten single-digit numbers in the decimal number system: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
- The number following 9 is 10.
- The number following 19 is 20, and so on.
Decimal numbers:
- Three hundred eight thousandths ⇒ 308/1000 ⇒ 0.308
- Sixty thousandths ⇒ 60/1000 ⇒ 0.060
Therefore, given numbers in the decimal numbers form are:

If point R(6, 2) is rotated 180 degrees clockwise about the origin, the new point would be R'(-6, -2)
<h3>What is a transformation?</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformations are r<em>eflection, translation, rotation and dilation.</em>
Rigid transformation are transformation that preserve the shape and size hence producing congruent figures such as translation, reflection and rotation.
If point R(6, 2) is rotated 180 degrees clockwise about the origin, the new point would be R'(-6, -2)

Answer:
Equation for the function: y=8x+20
Step-by-step explanation:
8 represents points per item/rate of change
20 represents the y intercept or what the person gains in the beginning that doesn't change.
8(16)+20
128+20
=148
After making 16 purchases the person will have 148 points.
