Answer:
x = 3/2 y + 3
Step-by-step explanation:
2x – 3y = 6.
Add 3y to each side
2x – 3y+3y = 3y+6.
2x = 3y+6
Divide each side by 2
2x/2 = 3y/2 + 6/2
x = 3/2 y + 3

Answer: 110 square cm
=======================================================
Explanation:
All sides of a regular polygon are the same length. So the bottom side is also 8 cm.
Draw lines from the center to each vertex of the pentagon. Five triangles form. Each triangle has a base of 8 and a height of 5.5 (since all five triangles are congruent)
area of one triangle = 0.5*base*height = 0.5*8*5.5 = 22
area of five triangles = 5*(area of one triangle) = 5*22 = 110
0.4x - 5 = 0.08x + 3 srry I forgot the x
Answer:
x= 25.
Step-by-step explanation:
To isolate "x", I first moved all terms containing x to the left side of the equation: 0.32x-5=3 (0.4-0.08=0.32). Then moved all terms not containing x to the right side of the equation: 0.32x=8. Finally, I divided 8 by 0.32 which equals 25. Thus, x=25. I hope this helped!

Since, Points P, Q, and R are collinear and Point Q is between P and R.
[tex] \therefore \: PR = PQ + QR \\ 13n - 10 = 4n + 3 + 6n + 8 \\ 13n - 10 = 10n + 11 \\ 13n - 10n = 11 + 10 \\ 3n = 21 \\ n = \frac{21}{3} \\ n = 7 \\ \\ PQ =4n + 3 = 4 \times 7 + 3 = 31 \\ QR = 6n + 8 = 6 \times 7 + 8 = 50 \\ PR = 13n - 10 = 13 \times 7 - 10 = 81[/tex]
Use f(x)=-3/2x+11, g(x)=x^2-7x, and h(x)=|15-9x| to evaluate the function h(2/3)= ________
Answer:
The answer is nine
Step-by-step explanation:
The required solution of the the function is 9.
It is required to evaluate the function.
What is function?A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Given :
Now the given function is,
f(x)= -3/2x+11
g(x)=x^2-7x
h(x)=|15-9x|
To evaluate the function
h(2/3)
Put x = 2/3 in h(x) we get,
h(x) = |15 - 9(2/3)|
h(2/3)= |15 - 18/3|
h(2/3)= |15 - 6|
h(2/3)= |9|
h(2/3)= 9
Therefore, the required solution of the the function is 9.

What would be the cost for 5 of the gift cards? $80 $90 $100 $110
Answer:

Step-by-step explanation:
The cost for 5 of the gift cards is $100. Therefore, option C is the correct answer.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
Given that, blue diamonds appear at points (1, 20), (2, 40), (3, 60), (4, 80).
Now, we will find m and c using the points (1,20) and (2,40)
Let x be the number of gifts cards and y is total cost (in $).
The slope, m = (40-20)/(2-1)
m = 20
Equation of straight line is given as,
y = mx + c
Put the value of m,
So, y = 20x + c
Substitute with the point (1,20) in y=20x+c, we get
20 = 20×1 + c
20 = 20 + c
c = 0
The equation of the line, y = 20x
To find the cost for 5 of the gift cards substitute with x = 5
y = 20×5 = 100
So, the cost for 5 of the gift cards = $100
Therefore, option C is the correct answer.

Step-by-step explanation:
For this problem, we will simply combine like terms after using the distributive property:
7x^2 + 3 - 5(x^2 - 4)
= 7x^2 + 3 - 5x^2 + 20
= 7x^2 - 5x^2 + 3 + 20

For the given octagon, if its diagonals are made then it will be divided into 8 triangles, such that each triangle will be equal to the other.
Now, if the area of a single triangle is calculated then the area of the triangle will be,
Area of triangle = (1/2) × b × h
Further, since there are 8 triangles, therefore, the area of the octagon can be written as,
Area of octagon = Area of triangle × 8
= (1/2) × b × h × 8
= 4bh
Hence, the area of the octagon is 4bh.
B.)
The formula can be solved for h as shown below,
Area of octagon = 4bh
A = 4bh
Divide both the sides by 4b, therefore, we can write,
A/4b = 4bh/4h
h = A/4b
Hence, the formula when solved for h will be equal to A/4b.

The definition of parallel lines requires the undefined terms line and plane, while the definition of perpendicular lines requires the undefined terms of line and point. What characteristics of these geometric figures create the different requirements?
Answer:
Parallel lines requires the terms line and plane because line and plane that are parallel cannot cross each other therefore they will never make a point of intersection. The characteristics of that parallel lines consists of lines and planes. Perpendicular lines requires the terms line and point because whenever two lines intersect, it creates a point and whenever two planes intersect, it creates a line. The characteristics of that perpendicular lines are points and lines.
The characteristics of the geometric figures that create the different requirements are;
Parallel lines are lines on the same plane and that are equidistant from each otherPerpendicular lines are lines that form a 90 degree angle at the point of their intersection.Reasons:
The characteristics of parallel lines are;
The shortest distance between the lines that are parallel is the same at all points along the lines.The lines are on the same plane.As the plane is extended indefinitely, the lines do not intersect.The characteristics of perpendicular lines are;
Perpendicular lines are lines that intersect at a point.Where two lines are perpendicular, the slope of one line is the negative reciprocal of the other, such that the product of the slopes of two lines that are perpendicular is -1.The angle formed at the intersection of perpendicular lines is 90°.An horizontal and a vertical line on the same plane are perpendicular to each other.Therefore, the characteristics of the geometric figures that create the different requirements are;

19. The midpoint of JK is M(0, 1). One endpoint is /(-6, 3). Find the coordinates of
endpoint K. (Section 1.3)
Answer:
(6,-1)
Step-by-step explanation:
let coordinates of K be (x,y) then
[tex]0=\frac{-6+x}{2}\\or~-6+x=0\\x=6\\1=\frac{3+y}{2}\\y+3=2\\y=2-3=-1\\so ~K~is ~(6,-1)[/tex]
The coordinates of endpoint K will be (6,-1).
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.
Given that the midpoint of JK is M(0, 1). One endpoint is (-6, 3). The other end will be calculated as below:-
0 = ( -6 + x ) / 2
-6 + x = 0
x = 6
The value of the y coordinate will be calculated as below:-
y = 2 - 3 = -1
Therefore, the coordinates of endpoint K will be (6,-1).

angle 2 = 103° ( vertically opposite angles )
angle 1 = angle 3
103° + 103° + 2 ( angle 1 ) = 360° ( angle 1 = angle 3 )
or, 206° + 2 (angle 1) = 360°
or, 2(angle 1) = 360 - 206
or, 2(angle 1) = 154°
or, angle 1 = 154/2 = 77°
Answer:angle 2 = 103° (vertically opposite angles)
angle 1 = angle 3 = 77° (vertically opposite angles)
