There are several other rules that go along with the power rule.such as the products to power rule and the quotient to power rule.
Log2 (x)=3
Log 2 × x=3
Log x=3-2
Log x=1
X=1
1/x = log2/3 (x)
Add 21 to both sides. -10+21 is 11. So x=11.
Coordinate of Q = (-10, -20)
Coordinate of P = (40, -20)
Distance = 40 - (-10) = 50 units
In vertical, x-coordinate would be same, and y will increase by 30, so -20 + 50 = 30
Coordinate of R = (-10, 30)
In short, Your Answer would be: Option 3
Hope this helps!
Answer: Choice A
Step-by-step explanation: You are given the inequality g is less than or equal to. Greater/less than and equal to, you use solid circle. Greater/less than, you use open circle. From there, you just look at the inequality in which direction is it going at and from there, you should be able to select your choice which happens to be the first one.
I hope this explanation helps.
Best to you!
