Answer:
-6x +9
Step-by-step explanation:
You're apparently expected to recognize that equation solution processes generally involve eliminating parentheses using the distributive property. When you do this, you get ...
... (-3)(2x) + (-3)(-3)
... = -6x +9

<em>Comment on the question</em>
Depending on the inequaltiy, you may want to divide by -3 first in your solution process. The question seems to assume there is One Right Way. In math, there is not.
Answer:
Speed = 20 mi/h
Explanation:
There are two points A and B
Distance between both the points are define with function -20t + 45 miles
where t represent the number of hours of travelling.
Now firstly we find the initial position. At starting time is 0, so we put t=0 in given function of t.
At t=0;
d₀ = -20(0) + 45 = 0 + 45 = 45 miles
Now we find the distance travell after starting first hour.
Than we put t = 1 in the given function
At t = 1;
d₁ = -20(1) + 45 = -20 + 45 = 25 miles
Difference between d₁ & d₀ is
45 - 25 = 20 miles
We see that in one hour, total distace is covered 20 miles
Now we use time, speed, distance relation
Speed = 
S = 
S = 20 miles/hour
That's the final answer.
I hope it will help you.
Answer: 379.94
Step-by-step explanation: To find the area of a circle, you do radius squared times pi. To find the radius, divide the diameter in half. So 22 divided by 2 is 11. 11 squared is 121. Then multiply 121 by 3.14. That equals to 379.94
Answer: $20.01
$20.99
$20
$80
$1,000
Step-by-step explanation:
The reason why is because they are $20 or more. if it was $19.99 then no.
The limits to the given function are as follows:
1. ∞
2. -∞
3. ∞
4. 1
5. -∞
<h3>What is a limit?</h3>
A limit is given by the <u>value of function f(x) as x tends to a value</u>.
For this problem, at x = 0, we have that to the left the function goes to positive infinity, while to the right it goes to negative infinity, hence:
1. lim f(x) = ∞
x->0-
2. lim f(x) = -∞
x->0+
At x = 2, the function goes to infinity to the left and to the right, hence:
3. lim f(x) = ∞
x->2
To the left of the graph, the function goes to negative infinity, while to the right it goes to 1, hence:
4. lim f(x) = 1
x-> ∞
5. lim f(x) = -∞
x-> -∞
