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]

Which set of numbers is arranged in increasing order?
O A.

3.14, 7, 2, VTO
Oc. 44, V1O. 3.14. 7
OD V10, 42, 3.14, 5
Answer:
[tex]\textsf{B.} \quad 3.14, \; \pi, \; \dfrac{22}{7}, \;\sqrt{10}[/tex]
Step-by-step explanation:
The given set of numbers (in any order) is:
[tex]\pi, \;\sqrt{10}, \; 3.14, \; \dfrac{22}{7}[/tex]
Convert each number to its decimal equivalent to 4 decimal places:
[tex]\implies \pi=3.1416\;(\sf 4\;d.p.)[/tex]
[tex]\implies \sqrt{10}=3.1623\;(\sf 4\;d.p.)[/tex]
[tex]\implies 3.14 = 3.1400\;(\sf 4\;d.p.)[/tex]
[tex]\implies \dfrac{22}{7}=3.1429\;(\sf 4\;d.p.)[/tex]
Each number has 3 units and 1 tenth.
Comparing the hundredths, all the numbers have 4 hundredths except √10 which has 6 hundredths. Therefore, √10 is the largest number since 6 > 4.
Comparing the thousandths of the other three numbers, 3.14 is the smallest number as it has zero thousandths.
π is the next smallest as it has a one thousandth.
Therefore, the given set of numbers in increasing order is:
[tex]3.14, \; \pi, \; \dfrac{22}{7}, \;\sqrt{10}[/tex]

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

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

The owner of a small store buys coats for $60.00 each. Answer parts a and b.
a. She sells the coats for $72.00 each. What percent of the purchase price is the sale price?
The sale price is
% of the purchase price.
The percent of the purchase price would be 20% of the sale price.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
First we need to calculate the difference between the purchase and sale price.
$72.00 - $60.00 = $12.00
Since $12 is the increase in dollars.
To increase as a percentage we need to divide the increase by the original purchase price.
12.00 ÷ 60.00 = 0.2
This simply means moving the decimal place two columns to the right;
0.2 x 100 = 20
Therefore, the percent of the purchase price would be 20% of the sale price.

Answer:
At the point where x = 2.
Step-by-step explanation:
First find the derivative which gives us the gradient of the tangent at any point on the curve:
y = 5x^2 - 16x
y' = 5*2 x^(2-1) - 16 x(1-1)
y' = 10x - 16.
y' is the gradient at point of coordinate x.
So when the gradient = 4:
4 = 10x - 16
10x = 20
x = 2.
Answer:
x=2
