Solve for x
-18x+21>-15 or 20x-13>27

All numbers between -2 and 2, not touching -2 or 2

Step-by-step explanation:

-18x+21>-15 simplifies to -18x > 36, which in turn becomes 18x < -36, or

x < -2.

20x-13>27 simplifies to 20x > 40, or x > 2.

Then the solution set is

(-2, 2):  All numbers between -2 and 2, not touching -2 or 2.

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
