Determine if the lines are parallel, perpendicular, or neither.
3y = -2x + 18 and 6x + 9y = 18
Parallel
Perpendicular
Neither
Answers
Answer:
parallel
Step-by-step explanation:
1st step get the equations in y=mx+b
3y = -2x + 18
(÷ each side by 3)
y = -2/3x + 6
6x + 9y = 18
(subract 6x to get it to the other side)
9y = -6x + 18
(÷ both sides by 9)
y = -6/9x + 2
(simplify -6/9)
y = -2/3x +2
2nd step look at the equations
y = -2/3x + 6 and y = -2/3x +2
The lines are at different places and will never touch, having same slope theres never a possibility they would look something like this \\

Answer:
b=100 and c=100
Step-by-step explanation:
Because 100 is across a no value which is also 100 because they are the same and the b and c sides too so they both are 100
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]100° + b = 180°[/tex]
Because they make straight line.
Also ;
[tex]100° + c = 180°[/tex]
Thus :
[tex]b = c[/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]100° + b = 180°[/tex]
Subtract sides 100°
[tex] - 100° + 100° + b = 180° - 100° \\ [/tex]
[tex]b = 80°[/tex]
So ,
[tex]b = c = 80°[/tex]

Use the graphs of f and g to describe the transformation from the graph f to the graph g
Answers
Answer:
The graph of g is a VERTICAL translation 2 unit(s) UP of the graph of f
The graph f(x) is translated vertically upward by 2 units to g(x).
Given that,
To describe the transformation from graph f to graph g.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
f(x) = -2x
Now,
g(x) = f(x) + 2
g(x) = -2x + 2
Implies f(x) is increased by 2 or graph translated 2 units upwards.
Thus, the graph f(x) is translated vertically upward by 2 units to g(x).

whats the answer to (5² -4) ∙ 2 – 18
Answers
Answer:
Solving the equation [tex](5^2 -4) \cdot 2 -18[/tex] we get 24
Step-by-step explanation:
We need to solve the equation [tex](5^2 -4) \cdot 2 -18[/tex]
We will solve using DMAS rule i.e first bracket will be solved, then multiplication and at the end subtraction will be done.
First we will solve the bracket
[tex](5^2 -4) \cdot 2 -18\\=(25-4) \cdot 2-18\\=21 \cdot 2-18[/tex]
Now multiply 21 by 2
[tex]=42-18[/tex]
Now subtract
[tex]=24[/tex]
So, solving the equation [tex](5^2 -4) \cdot 2 -18[/tex] we get 24

x²-4 / x²+9x+20 is greater than/equal to 0
Answers
Answer:
true
Step-by-step explanation:
x²-4/x²+9x+20 >=0
cross multiplying the equation we have,
(x²-4/x²+9x+20)*x²+9x+20 >= 0*x²+9x+20
= x²-4>=0
x²>=4
taking the square root of both sides, we have:
√x²>= √4
x >=2
What percent of 80 is 20
Answers
Answer:
25%
Step-by-step explanation:
If 45% of a number is 63 and 35% of the same number is 49, find 80% of that number.
Answers
Answer:
Step-by-step explanation:
1) Let the number be y
45%of y=63
45y/100=63
Y=6300/45
Y=140
So 80%of a number =80y/100
=80×140/100
=112.
Let the number be y
35%of y=49
35y/100=49
Y=4900/35
Y=140
So 80%of a number =80y/100
=80×140/100
=112.

In the rhombus, the measure of angle 1 = 18x, the measure of angle 2 = x + y, and the measure of angle 3 = 30z. Find the value of x + y + z. The diagram is not drawn to scale.
Answers
Answer:
A. 93
Step-by-step explanation:
Each angle is 90 degrees.
18x = 90
x=5
x + y = 90
5 + y = 90
y = 85
30z = 90
z = 3
5 + 85 + 3 = 93

A weight lifter does 9.8 J of work while lifting a weight straight upward through a distance of 0.12m. What was the force exerted by the weight lifter?
Answers
Answer:
The force exerted by the weight lifter is 81.7 N.
Step-by-step explanation:
We can find the force exerted by the weight lifter using the definition of work:
[tex] W = F*d [/tex] (1)
Where:
F: is the force
d: is the displacement
We have W = 9.8 J of work and d = 0.12 m, so by solving equation (1) for F we have:
[tex] F = \frac{W}{d} = \frac{9.8 J}{0.12 m} = 81.7 N [/tex]
Therefore, the force exerted by the weight lifter is 81.7 N.

The regular octagon shown is divided into 8 congruent triangles. Each triangle has an area of 2.17 square centimeters. The perimeter of the octagon is 48 centimeters. What is the length of each side of the octagon?
Answers
Answer:
The length of each side of the Octagon is 6 centimeters
Step-by-step explanation:
An Octagon is an 8 sided polygon
The perimeter of the octagon can be obtained by the addition of all the sides of the octagon
Since it is a regular octagon, it means that all the sides are of equal length
Mathematically, what this mean is that the perimeter of the Octagon is simply 8s
where s is the length of the side of the Octagon
Thus, mathematically, the length of each side of the Octagon will be 48/8 = 6 centimeters
