How to solve a quadratic equation by substitution?
The equation is first transformed into a more familiar form. Replace the substitutions with the original variables after factoring the problem. The difference of squares equation is used to finish the factorization and locate the answers for x.
Given, the equation for solving is: (x + 2)² - 2(x + 2) - 15 = 0 --(i)
Let in the equation, y = x + 2 --(ii)
Equating (i) and (ii), we get:
y² - 2y - 15 = 0 ⇒ y² - 5y + 3y - 15 = 0 ⇒ y(y - 5) + 3(y - 5) = 0

If the car cost a total of $4500 how many yards will you have to mow?
Step-by-step explanation:
You have found a used car and your parents have agreed to pay the first $750 for you. You have a summer job mowing yards for $25 per yard. Write and inequality that will calculate the number of yards (y) you will have to mow to get to at least the cost (C) of the car.
25y + 750 = C
If the car cost a total of $4500 how many yards will you have to mow?
25y + 750 = 4,500
subtract 750 from both sides:
25y + 750 - 750 = 4,500 - 750
25y = 3,750
divide both sides by 25:
25y/25 = 3,750/25
y = 150
Must mow 150 yards.
check:
25(150) + 750 = 4,500
3,750 + 750 = 4,500
4,500 = 4,500

A smiley face (orange) and its image (open) are graphed on the coordinate plane below. Which sequence of transformations maps the solid smiley face onto the open smiley face?A. reflect over x-axis, rotate 270° counterclockwiseB. rotate 270° counterclockwise, translate right 8 unitsC. translate up 8 units, reflect over y-axisD. reflect over y-axis, rotate 90° counterclockwise
The only way to check which one is the correct answer is to perform each set of transformations and check which one is the correct one. First, note that the initial position of the smiley face is the third quadrant. So, we will first apply vaguely the transformations to check to which one is the smiley face located in the first quadrant once we are done with the transformations.
So, let us analyze each set of transformations separately.

Describe a series of transformations Matt can perform to device if the two windows are congruent
We can generate congruent shapes by combining the three types of transformations: rotations, reflections, and translations. Actually, using a combination of one or more of these three transformations, any pairs of congruent shapes can be matched to one another.
What are transformations?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
Given Data
We now understand that the size and shape of the figures are preserved during stiff transformations (reflections, translations, and rotations). Pre-image and image are always congruent with one another.
Series of transformation Matt can perform:
Reflection (Flip)
Because the equivalent points from the pre-image to the image remain at the same distance from the line of reflection, a reflection maintains its original shape.
Rotations as a Transformation of Congruence
A rotation is when a figure turns. Although the figure is the same size and shape, it appears to have fallen over. A clock is a fantastic example of a rotation in the real world. Every hour or every day, the connecting arms of a clock revolve around its central point. The degree of rotation is used to characterize a rotation; popular rotations include 90 degrees, 180 degrees, and 270 degrees. The figure returns to its original position after a full 360-degree spin. A rotation must additionally include the direction, either clockwise or counterclockwise. A rotation's degree amount and direction can be computed using this information.
Congruence transformation through translation
When we move an object or shape from one location to another without changing its size, shape, or orientation, we call that movement a translation. A translation, often known as a slide, involves moving each point on an object or shape by the same amount and in the same direction.

If the length of a side of cube is "s", then total edge length (E = 12s), total surface area (A = 6s²) and Volume (V = s³).
As per the question statement, the length of a side of cube is "s".
We are required to write down the equations for total edge length "E", total surface area "A" and Volume "V" of the cube with respect to "s".
To solve this question, we need to know a couple of basic structural properties of a cube, that is,
There are 12 edges in a cube, all of equal length,
And, there are 6 faces in a cube, all of equal surface area.
[A reference image is attached hereby for better understanding;
The 12 edges of the cube are: AB, BC, CD, AD, CG, DH, BF, AE, EF, FG, GH and EH,
And, the 6 Faces of the cube are: ABCD, ABEF, CDGH, BCFG, ADEH and EFGH]
Therefore, total edge length (E) = (12 * s) = 12s,
Or, (E = 12s)
Total surface area (A) = [6 * (s)²] = 6s²,
Or, (A = 6s²)
[Since, area of a square of edge length "s" = s², and every face of a cube is a square]
Finally, Volume (V) of the cube = [s * s * s] = s³,
Or, (V = s³).

To find the two numbers that are located 5/8 of a unit from 1/6 on the number line, we have to first understand that for a number on a number line, there are numbers both ahead and behind the number.
So, the numbers that are 5/8 from 1/6 on the number line will be:
=> one number that is +5/8 from 1/6
=> one number that is -5/8 from 1/6
Therefore, the two numbers are:
[tex]\begin{gathered} \frac{1}{6}\text{ + }\frac{5}{8}\text{ and }\frac{1}{6}\text{ - }\frac{5}{8} \\ \Rightarrow\text{ }\frac{19}{24}\text{ and }\frac{-11}{24} \end{gathered}[/tex]Those are the two numbers.
