Consider the equation
muminat

Answer:

A. a=10\\ \\b\neq -8

B. a=10\\ \\b= -8

Step-by-step explanation:

Consider the equation

2(5x-4) = ax + b

A. This equation has no solutions when the coefficients at x are the same and the free coefficients are not the same.

First, use distributive property:

2(5x-4)=2\cdot 5x-2\cdot 4=10x-8

So, the equation is

10x-8=ax+b

This equation has no solutions when

a=10\\ \\b\neq -8

B. The equation has infinitely many solutions when the coefficients at x are the same and the free coefficients are the same too.

So, the equation

10x-8=ax+b

has infinitely many solutions when

a=10\\ \\b= -8

In other cases, the equation has a unique solution

Determine whether this statement is true or false. if two lines have the same slope, their equations describe the same line.
maksim [4K]

Answer:

False

Step-by-step explanation:

When you say "slope", Im guessing your referring to the gradient (the steepness of the line).

If two lines have the same gradient their equations won't usually describe the same line because their 'y intercepts' will be different (the point in which the line crosses the y axis)

Sean chewed 2/5 of his rawhide bones. If he had 10 bones to begin with, how many did he chew up?
Vesna [10]

Answer:

He chewed 4/10 of the bone

Step-by-step explanation:

Since the 10 will be the denominator you will need to divide it by 2 and get 5. After that you multiply the denominator of 10 and numerator of 1 by 2 and get 4/10
