Answer:

2.5 - 1.2x < 6.5 - 3.2x

add 3.2x to both sides;

2.5 + 2x < 6.5

minus 2.5 from both sides;

2x < 4

 x < 2

Step-by-step explanation:

This is the exact same as doing a linear equation, so brush up on this skill.

Answer:      x<2   or   xϵ(-∞; 2)

Step-by-step explanation:

Add +3.2x to both sides of inequality:

2.5-1.2x+3.2x<6.5-3.2x+3.2x

2.5+2x<6.5

Deduct 2.5 from both sides of inequality:

2.5-2.5+2x<6.5-2.5

2x<4

Divide both sides of inequality by 2

2x/2<4/2

x<2   or   xϵ(-∞; 2) ( the answer can be written in 2 ways)

Which equation is represented by the intersection of the graphs below?<br><br> Image is above.
zaharov [31]

Option B:

sin x = 1 is the equation represented by the intersection of the graph.

Solution:

The graph lies between -1 and 1 in y-axis.

x-axis of the graph is all real numbers.

The graph oscillates between -1 and 1 and a shape that repeats itself every 2π units.

That is the domain of the graph is all real numbers.

The range of the graph is [-1, 1].

It clearly shows that, it is the graph of sinx = 1.

Hence sin x = 1 is the equation represented by the intersection of the graph.

Option B is the correct answer.
