Step-by-step explanation:
Answer:
(x - 1)² = 16
Step-by-step explanation:
x² - 2x - 15 = 0
x² - 2x + 1 = 15 + 1
(x - 1)² = 16
3(2x+4) = 6x + 8

How to find angles in intersected lines?When lines intersect, angle relationships are formed such as vertically opposite angles, linear angles angles on a straight lines.
Therefore, angle 2x + 2 is vertically opposite to the angle 3x - 52 .
Vertically opposite angles are congruent to each other.
Vertical Angles are the angles opposite each other when two lines cross. in other words, vertical angles are formed when two lines meet each other at a point.
Hence,
2x + 2 = 3x - 52
2x - 3x = -52 - 2
- x = -54
Therefore,
x = 54

The 56th term of the following arithmetic sequence 7,10,13,16 is 172.
What is the arithmetic sequence?
A series of numbers called an arithmetic progression or arithmetic sequence has a constant difference between the terms.
Here, we have
Given
Arithmetic sequence 7,10,13,16.
We have to find the 56th term.
The common difference between terms: 10 - 7 = 3

What is a annual inflation rate?
A percentage is used to represent the inflation rate. For instance, a yearly inflation rate of 2% indicates that the cost of products and services as a whole has increased by 2%. As an illustration, a product that cost $10 last year will cost $10.20 this year.
Here, we have
Given
The cost of the gallon of milk earlier was $2.81
The cost of a gallon of milk now is $3.48.
The total time period is 10 years.

Part B: A turnpike's route is determined by the equation y equals one third times x squared period Prove algebraically how many intersections there will be between the railroad and the turnpike, showing all necessary work. (5 points)
a) The number of intersections between the railroad and the highway is of: One.
b) The number of intersections between the railroad and the turnpike is of: Two.
How to define the linear function?The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which the parameters are listed as follows:
m is the slope, representing by how much y changes when x is increased by one.b is the intercept, representing the value of y when x = 0.The points for the railroad are given as follows:
(-8, 0) and (0,5).
When x = 0, y = 5, hence the intercept is of:
b = 5.
When x increases by 8, y increases by 5, hence the slope is of:
m = 5/8.
Thus the equation for the railroad is of:
y = 5/8x + 5.
Then the number of intersections with the highway is of one, as they are linear functions with different slopes.
With the turnpike, the intersection is given as follows:
5/8x + 5 = x²/3
x² -1.875x - 15 = 0.
The discriminant is of:

Which table of values represents the equation y = 7x - 3?
The table of values which represent the equation y = 7x - 3 is: table D.
What is an ordered pair?In Mathematics, an ordered pair can be defined as a pair of two (2) elements or points that are commonly written in a fixed order within parentheses as (x, y), which represents the x-coordinate or x-axis (abscissa) and the y-coordinate or y-axis (ordinate) on the coordinate plane of any graph.
In order to determine the true ordered pair that is a solution for the given linear equation, we would have to test the ordered pair contained in each table by substituting it into the linear equation as follows;
For ordered pair (-2, -1), we have:
y = 7x - 3
-1 = 7(-2) - 3
-1 = -14 - 3
-1 = -17 (False).
For ordered pair (-2, -19), we have:
y = 7x - 3
-19 = 7(-2) - 3
-19 = -14 - 3
-19 = -17 (False).
For ordered pair (-2, -15), we have:
y = 7x - 3
-15 = 7(-2) - 3
-15 = -14 - 3
-15 = -17 (False).
For ordered pair (-2, -17), we have:
y = 7x - 3
-17 = 7(-2) - 3
-17 = -14 - 3
-17 = -17 (True).
In this context, we can logically deduce that all of the coordinates in table D represents the equation y = 7x - 3.

• March: 7% more water bottles in February
• April: 500 more water bottles in March
What is the percent change, to the nearest percent, in the number water bottles the company manufactured from February to April. show your work
Answer:
19%
Step-by-step explanation:
You want the change from February to April if 4100 bottles were manufactured in February, 7% more were manufactured in March, and 500 more were manufactured in April.
ChangeThe change from February to March is given as 7%.
The change from March to April is 500 bottles. In terms of the February quantity, this is ...
500/4100 × 100% ≈ 12.2%
Then the total of changes from February to April is ...
change = 7% +12.2% = 19.2% ≈ 19%.
The number of bottles manufactured increased by about 19% from February to April.
__
Additional comment
When working with percentages, one must always be aware of the base amount—what it is that represents 100%. Here, we know the 7% number for March uses the February value as its base.
Since we want a percent change from the February base, we can use that same base to find the percent difference from March to April. Then the total difference from February is the difference to March plus the difference from March to April.

What is a square root of a number?
In mathematics, the square root of a number is a value that gives the original number on multiplication by itself. The positive number, when multiplied by itself, represents the square of the number. Thus, the square root of the square of a positive number gives the original number.
Using Prime Factorization:
The first step in this method is to find the prime factors of 80.
80 = 2 × 2 × 2 × 2 × 5
To find the root from here, we can simplify this to
√80 = √(2 × 2 × 2 × 2 × 5)
√80 = 4√5
