Answer:

A. a = 0, b = 2

B. a = 10, b = 0

C. a = 10, b = -8

Step-by-step explanation:

2(5x-4)=ax+b

10x - 8 = ax + b

When a = 10, b = -8

This equation becomes true for all x. Hence infinite solutions.

When a = 10, b is not -8,

This equation has no solution.

One possible combination could be:

a = 10, b = 0

When a is not 10,

The two sides of the equation become two non parallel lines which will intersect at one point.

A combination could be:

a = 0, b = 2

Using the numbers 0-6 once, make 2 equivalent ratios
fenix001 [56]

Step-by-step explanation:

As we have to use the number 0-6 once to make 2 equivalent ratios.

so lets solve the problem.

Determining first equivalent ratio

as

  • 5 times 2 = 10

and

  • 32 times 2 = 64

so

  • Together will get 10/64

Therefore, first equivalent ratio

\:\frac{5}{32}=\frac{10}{64}

Determining second equivalent ratio

\frac{13}{65}=\frac{4}{20}

as

\frac{13}{65}=\frac{1}{5}

and

\frac{4}{20}=\frac{1}{5}

Therefore, second equivalent ratio

\frac{13}{65}=\frac{4}{20}

Which of these expressions are equivalent? Show your work
ivanzaharov [21]

Answer:

7(2+3x)-3x and 4(3+3x)+2(1+3x)

Step-by-step explanation:

7(2+3x)-3x

= 14 + 21x - 3x

= 18x + 14

2(6x+7)+10x

= 12x + 14 + 10x

= 22x + 14

4(3+3x)+2(1+3x)

= 12 + 12x + 2 + 6x

= 18x + 14

7(2+3x)-3x and 4(3+3x)+2(1+3x) are equal expressions.
