The lines represented by the equations y=\frac{4}{5}x+8y= 5 4 x+8 and 20y+25x=18020y+25x=180 are
Given:
The equations of lines are
[tex]y=\dfrac{4}{5}x+8[/tex]
[tex]20y+25x=180[/tex]
To find:
The relation between two of lines.
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
We have,
[tex]y=\dfrac{4}{5}x+8[/tex] ...(i)
[tex]20y+25x=180[/tex] ...(ii)
Equation (i) can be written as
[tex]20y=-25x+180[/tex]
[tex]y=\dfrac{-25x+180}{20}[/tex]
[tex]y=\dfrac{-25x}{20}+\dfrac{180}{20}[/tex]
[tex]y=\dfrac{-5x}{4}+9[/tex] ...(iii)
On comparing (i) with slope intercept form, we get
[tex]m_1=\dfrac{4}{5}[/tex]
On comparing (iii) with slope intercept form, we get
[tex]m_2=-\dfrac{5}{4}[/tex]
Now,
[tex]m_1\times m_2=\dfrac{4}{5}\times (-\dfrac{5}{4})[/tex]
[tex]m_1\times m_2=-1[/tex]
The product of slopes of both lines is -1. We know that the product of slopes of two perpendicular lines is -1.
Therefore, the given lines are perpendicular.

Find the slope that passes through the line (9, 3) and (2, 7)
Answer:
-4 / 7
Step-by-step explanation:
m = (y2 - y1) / (x2 - x1)
m = (7 - 3) / (2 - 9)
m = 4 / -7
m = -4 / 7
OR
m = (y2 - y1) / (x2 - x1)
m = (3 - 7) / (9 - 2)
m = -4 / 7
At the zoo the ratio of monkeys to gorillas is 5:1 if there were 20 monkeys how many gorillas would there be?
Answer:

Directions: Solve for x. Round to the nearest tenth. 16" N 37
The value of x is: x = 35.57.
Here, we have,
given that,
from the given diagram, we get,
it is a right angle triangle,
base = x
hypotenuse = 37
and angle = 16°
now, we know that,
cos θ = adjacent / hypotenuse
so, we get,
cos 16° = x/37
The value of cos 16° is equal to the x-coordinate (0.9613).
∴ cos 16° = 0.9613.
=> 0.9613 = x/37
=> x = 35.57
Hence, The value of x is: x = 35.57.

Olivia has five bracelets and three necklaces. She wants to choose one bracelet and one necklace randomly. How many possible outcomes are in this sample space?
Answer:
15 possible outcomes
Step-by-step explanation:
Given: Olivia has five bracelets and three necklaces.
She chooses one bracelet and one necklace randomly.
To find: Number of possible outcomes in a sample space
Solution:
Sample space denotes a set of all possible outcomes.
Number of possible outcomes in a sample space = [tex]\binom{5}{1}\binom{3}{1}[/tex]
Use [tex]\binom{n}{1}=n[/tex]
Therefore,
Number of possible outcomes in a sample space = [tex]\binom{5}{1}\binom{3}{1}[/tex] = [tex]5(3)=15[/tex]

Solve the following systems of equations without graphing
5x + 10y = 30
-5x +15y = 20
Answer:
(2, 2)
Step-by-step explanation:
In this case, elimination would be the most efficient means of solving.
Simply, add the two equations, and you will be left with only one variable to solve for. (In this case y) You are then able to take your solution and plug it into an equation and solve for x, therefore giving you their intercept.\
5x + 10y = 30
+
-5x + 15y = 20
(x's cancel) 25y = 50
25y = 50
y = 2
5x + 10(2) = 30
5x + 20 = 30
5x = 10
x = 2
The solution to this equation is (2, 2)

Complete the steps below to solve this problem and others like it.
Part A
Alan weighs 3 pounds more than twice what Dylan weighs. Write an explession to represent Alan's weight in terms of Dylan's weight.
Answer:
Step-by-step explanation:
a=2d+3
b=3d-12
c=a+b so
c=2d+3+3d-12
c=5d-9
Answer:
2d + 3
Step-by-step explanation:
Dylan’s weight is d.
Twice Dylan’s weight is 2d.
Three pounds more than twice Dylan’s weight is 2d + 3.
So, the expression for Alan’s weight in terms of Dylan’s weight is 2d + 3.
What is m∠1?....................
answer is 147
hope that helped
Answer:
m∠1 = 147°
Step-by-step explanation:
triangle = 180°
117 + 30 = 147
180 - 147 = 33
line = 180°
180 - 33 = 147
m∠1 = 147°
