Consider the following conditional statement.If a + 1 = b, then b > a.

A. Create a pair of values for a and b in which the numerical relationship shown in the given conditional statement is true. In your final answer, include the values of the variables and proof of truth.
B. Is it possible to create a pair of values for a and b in which the numerical relationship shown in the given conditional statement is false? Use complete sentences to explain your answer.

Answers

Answer:

Step-by-step explanation:

Part A:

Lets take the value of a=10

Thus a+1=b

10+1=11 , it means the value of b is 11

11>10 or b>a

Now take the value of a as -3

Therefore a+1=b

-3+1= -2

-2>-3 or b>a

The pair of values for a and b are: a=10 then the value of b would be 11;

And a=-3; then the value of b would be: -2.

Part B:

It is not possible to create a pair of values for a and be, in which the numerical relationship shown in the given conditional statement is false, therefore b>a if a+1=b....

Multiply the binomials (3x - 5) and (4x + 6).

Answers

Answer:

12x² - 2x - 30

Step-by-step explanation:

When multiplying binomials, remember to follow the FOIL method:

FOIL =

First

Outside

Inside

Last

Follow FOIL: (3x - 5)(4x + 6)

(3x)(4x) = 12x²

(3x)(6) = 18x

(-5)(4x) = -20x

(-5)(6) = -30

Combine like terms, simplify:

12x² + 18x - 20x - 30

12x² + (18x - 20x) - 30

12x² - 2x - 30

12x² - 2x - 30 is your answer.

Plis help me!!

Answers

Answer:

x = 4

Step-by-step explanation:

Given

- 8 - x = x - 4x, that is

- 8 - x = - 3x ( add 3x to both sides )

- 8 + 2x = 0 ( add 8 to both sides )

2x = 8 ( divide both sides by 2 )

x = 4

Answer:x=4

Step-by-step explanation:

-8-x=x-4x

-8=-4x+x+x

-8=-2x

divide both sides by -2

x=4

Step-by-step explanation:

which statement is true for the pair of fractions shown? A 4/6 is equal to 9/12. B 4/6 is less than 9/12 C 4/6 is greater than 10/12. D 4/6 is greater than 10/12​

Answers

To figure this out, we just need to simplify as much as we can for each problem, and then find a common denominator.

A

4/6 = 9/12

2/3 = 3/4

this is false

B

4/6 < 9/12

2/3 < 3/4

8/12 < 9/12

this is true, but let's look at the others just in case

C

4/6 > 10/12

2/3 > 5/6

4/6 > 5/6

this is false

D

It looks like C and D are the same. This means D is also false.

So B is the only true statement

Answer: B
