What a false conditional statement that has a true converse

A conditional statement is any statement in the "If..., then..." form. The converse switches the hypothesis and the conclusion. It's easiest to demonstrate this in an example:

Our statement will be "If an animal is a dog, then it has four legs." Now to switch the hypothesis and conclusion, we take the "an animal is a dog" part, and switch it with the "it has four legs" part". I will change the wording slightly so the sentence still makes grammatical sense: "If an animal has four legs, then it is a dog".

Now the final statement from the previous example serves as the perfect false conditional statement with a true converse:

Statement: "If an animal has four legs, then it is a dog", clearly false.

Converse: "If an animal is a dog, then it has four legs", a true statement.

URGENT NEEDS ANSWERED RIGHT AWAY Talk of the Town is a cell phone provider. They charge by the month. The first month of service costs $72.99. The second month of service costs $101.44. The third month of service costs $129.89. Write an equation in the form of y=c+d(x−1) to represent this situation. Explain how you got your equation.

Answer:

Step-by-step explanation:

If we are to write an equation of the form , then the function is linear; therefore, it has a constant slope .

The slope of the function is given by

thus we have

Now we find from the fact that the first month of service costs $72.99, which gives us , or

Substituting the values of and , we get our equation in the final form:

Thirteen less than one fifth of a number equals 58. Write an equation for this situation and then find the number.

Thirteen less than one fifth of a number equals 58.

Convert it to equation is equal to:

13 - (1/5)x = 58

So we need to find the value of x by simplifying.

13 - (1/5)x = 58

-1/5 x = 45

x = -225

So the value of x is equal to -225.

Convert it to equation is equal to:

13 - (1/5)x = 58

So we need to find the value of x by simplifying.

13 - (1/5)x = 58

-1/5 x = 45

x = -225

So the value of x is equal to -225.

What is the y-value of the vertex of the function f(x) = –(x + 8)(x – 14)? The y-value of the vertex is ______

F(x) = - (x + 8)(x - 14)

The zeros (solutions) to the function are -8 and 14.

The vertex lies between these two values. Eleven is the 'x' value of the vertex. To find the y values, plug 11 into the function and solve for y.

f(11) = -(11+8)(11-14)

f(11) = -(19)(-3)

f(11)= - (-57)

f(11) = 57

The zeros (solutions) to the function are -8 and 14.

The vertex lies between these two values. Eleven is the 'x' value of the vertex. To find the y values, plug 11 into the function and solve for y.

f(11) = -(11+8)(11-14)

The length of a rectangle is 8 inches more than three times the width. the perimeter is 88 inches. find the length and width.

We can say L as length and W as the width

L= 3w + 8

The formula for perimeter is 2L + 2W = P. We can substitute L in as "3w+8" to make the equation...

2(3w+8)+2w=88 Now, we can simplify by distributing the 2 to each term

6w+16+2w=88

8w+16=88 Then subtract 16 from each side..

8w=72

w=9

So the width is 9, so we can substitue that into the previous equation, L = 3w+8.

L=3(9)+8

L=27+8

L=35, W=9

L= 3w + 8

The formula for perimeter is 2L + 2W = P. We can substitute L in as "3w+8" to make the equation...

2(3w+8)+2w=88 Now, we can simplify by distributing the 2 to each term

6w+16+2w=88

8w+16=88 Then subtract 16 from each side..

8w=72

w=9

So the width is 9, so we can substitue that into the previous equation, L = 3w+8.

L=3(9)+8

L=27+8

L=35, W=9

Graph the system of equations.

{6x−4y=−24 4x−8y=−32

6x - 4y = - 24

4x - 8y =- 32

10 x - 12y = -56

4x - 8y =- 32

10 x - 12y = -56

I think the answer is (-2,3) I hope this helps
