To solve this, since you know that h(x) is 11 and that it also equals -4x+3, you set them equal to one another which would look like this: 11=-4x+3.
Then, to solve for x, which is what I am assuming the question is asking, you would subtract 3 from both sides to isolate -4x, which would result in this:
-4x=8
Now, to solve for x, divide both sides by -4, and you get your answer which is x=-2
Answer: ~5
Step-by-step explanation:
It's been awhile for me but I think you do sin=opp/hyp
sin(45)=3sqrt(2)/x
x = 3sqrt(2)/sin(45) = (approx) 5
Answer:

Step-by-step explanation:
We have the following variables:
y: hours of sleep
x: age
Each day, a young person should sleep 9 hours
This means that y is 9 added to something
plus 1 4 hour for each year that the person is under 18 years of age.
For each year the person is under 18 years of age, she should sleep 1/4 = 0.25h on top of the 9 hours.
So the equation relating hours of sleep y and age x is:

Use the compound amount formula: A = P(1 + r/n)^(nt).
Here we have
A = $1500(1 + 0.023/2)^(2t), where t is the number of years.
Answer:
16x^2 - (12+12)x + 9
16x^2 -12x -12x +9
4x(4x-3)-3(4x-3)
(4x-3)(4x-3)
hence length of one side is 4x-3
