Which system of inequalities is represented by the graph?

a. y< or equal to 3x
y> -2x-1

b. y> 3x
y < or equal to -2x -1

c. y< -3x
y > or equal to 2x -1

d. y > - 3x
y < or equal to 2x -1

Option A. ,

Step-by-step explanation:

we know that

Inequality of the solid blue line

The solution is the shaded area below the solid blue line

The slope of the blue line is positive

The equation of the solid blue line is

so

The equation of the inequality is equal to

Inequality of the dashed red line

The solution is the shaded area above the dashed red line

The slope of the dashed red line is negative

The equation of the dashed line is

so

The equation of the inequality is equal to

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
