What a false conditional statement that has a true converse

Answers

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.

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

Answers

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.

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

Answers

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

Answers

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
