The boundary line of a linear inequality passes through the points (3,0) and (0,6). The points (3,0) and (2,6) are not solutions of the inequality. Write the linear inequality
Answer:
[tex]y<-2x+6[/tex]
Step-by-step explanation:
The boundary line of a linear inequality passes through the points (3, 0) and (0, 6).
The points (3, 0) and (2, 6) are not solutions of the inequality.
We want to find the equation of the linear inequality.
First, we will simply find the line that crosses the points (3, 0) and (0, 6).
We can determine the slope to be:
[tex]\displaystyle \frac{6-0}{0-3}=\frac{6}{-3}=-2[/tex]
Notice that (0, 6) is the y-intercept.
Then by the slope-intercept form:
[tex]y=mx+b[/tex]
Our equation will be:
[tex]y=-2x+6[/tex]
Now, we will need to determine our inequality sign.
First, (3,0) is on the boundary line yet it is not a solution. Therefore, our line is dotted. That is: we do not have the "or equal to" statement.
So, our inequality signs can only be either < or >.
We are given that (2, 6) is not a solution.
So, we can test for the sign. Substitute 2 for x and 6 for y:
[tex]\displaystyle 6\text{ }?\text{ }-2(2)+6[/tex]
Evaluate:
[tex]\displaystyle 6\text{ } ?\text{ } 2[/tex]
Since 6 is not a solution, the above statement needs to be false.
It will be false is the sign is <, since 2 is not greater than 6.
Therefore, our sign is <.
And our inequality is:
[tex]y<-2x+6[/tex]

64/109 ≈ 0.5872
Step-by-step explanation:
41 + 23 = 64 of the events have outcome E.
An additional 35 + 10 = 45 do not.
The probability of an outcome of E is 64 out of a total of 64+45 = 109 events.
P(E) = 64/109 ≈ 0.5872

Choose the triangle in which angle 2 is not an exterior angle.
help me...new freinds?
Answer:
The third triangle
Step-by-step explanation:
The Exterior Angle is the angle a side of a shape and a line extended from the side next to it.
So for example, the first picture shows an exterior angle because a line was extended and it forms an angle with the triangle's side.
The second picture is still an exterior angle because the angle is formed with an extended line and the triangle's side.
The third photo shows an angle formed between a random line and the triangle's side. This is not an exterior angle because the angle is not formed with any side's extension.
The fourth photo is an exterior angle because it shows the angle being formed with an extension of a line from the triangle and a side of the triangle.
Hope this helps! Feel free to ask any questions! :)
Answer:
C the third triangle. Hope this helps

Answer:
$20 was the original price. 16÷20= .8=80%
Answer:
The original price is 100%. and 80%
Step-by-step explanation:
The original price is 100%. and 80%=$15. ⇒1%=$1580=$0.1875. ⇒100%=$0.1875×100=$18.75.
Ryan bought a brand new car for $18,000. Its value depreciated at a rate of 1.2%.
Write a function to represent the value of the car as a function of time.
A. v(t)=18000(0.012)^t
B.V(t)=18000(1.2)^t
C.v(t)=18000(98.8)^t
D(t)=18000(0.988)^t
Answer:
A(t)= 18000(0.988)^t
Step-by-step explanation:
Given data
Ryan bought a brand new car for $18,000
Its value depreciated at a rate of 1.2%
Let us use the compound expression
A= P(1-r)^t
substitute
A= 18000(1-0.012)^t
A(t)= 18000(0.988)^t
Hence the expression is A(t)= 18000(0.988)^t
A function to represent the value of the car as a function of time is v(t) = 18000(0.988)^t
Exponential functionThe standard exponential equation is in the form y = ab^x
b is the rate which can be growth or decline
If the value of b < 1, it is a depreciationIf the value of b > 1, it is an appreciationIf Ryan bought a brand new car for $18,000 and its value depreciated at a rate of 1.2%, the exponential equation represented by this statement is;t
v(t) = 18000(1-0.0012)^t
v(t) = 18000(0.988)^t
Hence a function to represent the value of the car as a function of time is v(t) = 18000(0.988)^t

A toll road company has two plans for customers. One plan charges $10 per month for rental of a transponder (a box that identifies your car on the toll roads) plus $0.60 per mile driven. The second plan does not require that you rent a transponder. Instead, it charges customers $0.75 per mile driven on the toll road. Find the minimum number of miles you would need to drive in a month to make the first deal a better deal.
Answer:
The minimum number of miles you would need to drive in a month to make the first deal a better deal is 66.6 miles.
Step-by-step explanation:
For the first deal to be a better deal it has to cost less than the second plan and you can write an equation in which the first plan has a lower cost than the second one:
10+0.60m<0.75m, where:
m is the number of miles driven
Now, you can solve for m:
10<0.75m-0.60m
10<0.15m
10/0.15<m
m>66.6
According to this, the answer is that the minimum number of miles you would need to drive in a month to make the first deal a better deal is 66.6 miles.

from the basic knowledge of Angels in a trapezium
115 + 18 y + 10y + ( 3y + 6) = 360
31y + 120 = 360
31y = 320-120
31y = 240
y = 240/31

You are given $400 as a graduation gift. You decide to place the money in a savings account with an annual interest rate of 7.5% for 9 months. Find the amount of interest you will earn
Answer: $22.50
Step-by-step explanation:
The interest will be gotten by using the formula:
= PRT
= Principal × Rate × Time
= 400 × 7.5% × 9/12
= 400 × 0.075 × 0.75
= $22.50
The interest is $22.50
Tyler bought two pieces of pizza and three diet Pepsi for $7.25 Scotty but for pizzas a pizza and diet Pepsi for $8.25 set up a system of equations to determine how much a slice of pizza cost and how much a diet Pepsi cost
Answer:
The cost of
1 slice of pizza = x = $1.75
1 diet pepsi = y = $1.25
Step-by-step explanation:
Let us represent:
The cost of
1 slice of pizza = x
1 diet pepsi = y
Tyler bought two pieces of pizza and three diet Pepsi for $7.25
2x + 3y = 7.25.......Equation 1
Scotty but four pizzas and a diet Pepsi for $8.25
4x + y = 8.25......Equation 2
Combining the Equations
2x + 3y = 7.25.......Equation 1
4x + y = 8.25......Equation 2
y = 8.25 - 4x
We substitute 8.25 - 4x for y in Equation 1
2x + 3(8.25 - 4x) = 7.25
2x + 24.75 - 12x = 7.25
Collect like terms
24.75 - 7.25 = 12x - 2x
17.5 = 10x
x = 17.5/10
x = $1.75
Solving for y
y = 8.25 - 4x
y = 8.25 - 4(1.75)
y = 8.25 - 7
y = $1.25
Therefore,
The cost of
1 slice of pizza = x = $1.75
1 diet pepsi = y = $1.25
