5th grade math ! plz answer 1.,2.,3.,4.

Step-by-step explanation:

1. 10 to the power of 1 is 10 so 9x10 = 90

2. 8x1000 = 8000

3. 10 to the power of 2 = 100 so 5x100 = 500

4. 10 to the power of 5 is 100,000 so 2x100,000 = 200,000

1. 90

2. 8000

3. 500

4. 200,000

Step-by-step explanation:

we don't have enough info to solve this

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
