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

Answers

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]

HELP In △ABC, m∠A = 75° and m∠C = 20°, What is m⁢∠⁡⁣B?

Answers

180-(75+20)=180-95=85 B

To solve this question, we must know the the angle sum property of a triangle. Therefore the value of ∠⁡⁣B is 85° when ∠A = 75° and ∠C=20° in △ABC

What is angle sum property of a triangle?

According to angle sum property of a triangle, the sum of all angles of a triangle is always 180 degree. It can never be more than or less than 180 degree. If two angles of a triangle is given then the third angle can be calculated by subtracting the sum of two angle from 180°

The sum of the three angles in a triangle = 180° , that is

∠ A + ∠ B + ∠ C = 180°

Substituting the given values in the given equation we get

75° + ∠ B + 20° = 180°

∠ B + 95° = 180°

subtracting 95° from both sides we get

∠ B = 85°

Therefore the value of ∠⁡⁣B is 85° when ∠A = 75° and ∠C=20° in △ABC

Step-by-step explanation:

Given that :

Number of stickers sold = y

Cost of sticker = 50

Cost of bag tag = 75

Number of bag tags sold = x

Total worth of items sold ≥ 1000

50y + 75x ≥ 1000

To make atleast 15 stickers

y ≥ 15

Atleast 15 stickers :

How to determine why he might be wrong

From the question, we have the following parameters that can be used in our computation:

Rate = 1/3 miles in 4 minutes

When converted to unit rate, we have

Rate = 1/3 miles/4 minutes

Evaluate the quotient

So, we have

Rate = 1/12 miles per minute

This means that a possible error is (c) C.12×4 does not equal 13.

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.

Answers

20%

First we calculate the difference between the purchase and sale price.

$72.00 - $60.00 = $12.00

$12 is the increase in dollars. In order to increase as a percentage it is now necessary to divide the increase by the original purchase price.

12.00 ÷ 60.00 = 0.2

To get the final percentage we multiply the answer by 100. This simply means moving the decimal place two columns to the right.

0.2 x 100 = 20

Therefore the percent of the purchase price is 20% of the sale 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.

A circular flower bed is 24 m in diameter and has a circular sidewalk around it that is 2 m wide. Find the area of the sidewalk in the square meters.

Answers

The area of the sidewalk is 144.44 m².

The 2-m wide walk adds 4 m to the diameter, making it 21+4=25.

Since the radius is half the diameter, r = 25/2 = 12.5.

The area of the entire bed with walkway is 3.14(12.5)² = 490.625 m².

The diameter of the bed is 21, so the radius is 21/2 = 10.5.
The area of just the flower bed is 3.14(10.5)² = 346.185.

The difference between the two is 490.625-346.185 = 144.44 m². This is the area of the walkway.

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

Answers

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 function

The 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 appreciation

If 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
