Answer:

Simplifying

4x + 9 = 12x + -3

Reorder the terms:

9 + 4x = 12x + -3

Reorder the terms:

9 + 4x = -3 + 12x

Solving

9 + 4x = -3 + 12x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12x' to each side of the equation.

9 + 4x + -12x = -3 + 12x + -12x

Combine like terms: 4x + -12x = -8x

9 + -8x = -3 + 12x + -12x

Combine like terms: 12x + -12x = 0

9 + -8x = -3 + 0

9 + -8x = -3

Add '-9' to each side of the equation.

9 + -9 + -8x = -3 + -9

Combine like terms: 9 + -9 = 0

0 + -8x = -3 + -9

-8x = -3 + -9

Combine like terms: -3 + -9 = -12

-8x = -12

Divide each side by '-8'.

x = 1.5

Simplifying

x = 1.5

Identify the reciprocal of each number. Type it in the blank, using a slash () to show a fraction,

amid [387]

Answer: 6/5

Step-by-step explanation:

When finding the reciprocal, we essentially just "flip" or take the inverse of the number we are given. For example, the reciprocal of 1/2 would be 2/1 or 2. The given number multiplied by the reciprocal should always equal 1. If it does, then we know we are correct.

In this case, we are finding the reciprocal of 5/6, so we "flip" the numerator and the denominator to get 6/5.

To check our work, we need to multiply our original number and its reciprocal.

5/6 x 6/5 = 30/30 = 1

Now, we know we are correct, that the reciprocal of 5/6 is 6/5.

If a and b are positive, then a-b is positive identify the conclusion of the statement

Elanso [62]

Answer:

The statement is wrong. a-b can be positive but not always.

Step-by-step explanation:

There can be three possible situations that are:

Now taking first condition, the result will be positive because a smaller integer is subtracted from a greater one. Such as 5-2=3

In second condition, the result will be negative because a greater integer is subtracted from smaller one. Such as 2-5= -3

In the third condition, the result will always be zero because both the integers will cancel each other. Such as 5-5=0

The two equations:
Daisy’s: y = 4x + 14
Donald’s: y= 2x + 26

The point of intersection is (6, 38)
This point refers to how many of passengers it will take for both equations to have have the same cost output.

Daisy’s deal is better if you have less than 6 passengers. We can tell because the line for the equation is lower than Donald’s line. Donald’d deal will be better if you have more than 6 passengers since the line is lower than daisy’s deal.
