Marco is driving to the grand canyon. his distance from the grand canyon decreases 150 miles every 3 hrs. After 4 hrs, his distance from the Grand Canyon is 200 miles. Marco's distance from the Grand Canyon in miles, y, is a function of the number of hours he drives, x. Find the initial value.
Answers
Answer:
The initial value is 400.
The situation is described by a linearfunction of the form where:
m = slope/rate of change
b = initial value
In this case, the distance y is decreasing 150 miles every 3 hours. So the rate of change (m) is equal to:
-150/3 = -50 miles per hour
Now we know that after 4 hours, his distance is 200 miles. We can plug in x = 4 and y = 200 into the linear equation.
200 = -50(4) + b
200 = -200 + b
400 = b

Answer:
fourth option
Step-by-step explanation:
Given f(x) then f(x + a) represents a horizontal translation of f(x)
• If a > 0 then a shift left of a units
• If a < 0 then a shift right of a units
Thus
f(x) = (x - 11)³ ← has been translated right by 11 units
Given f(x) then f(x) + c represents a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Thus
f(x) = (x - 11)³ + 4
represents a translation 11 units right and 4 units up

There seems to be a mistake in typing. You probably type the letter "i" as "1", so it is difficult to tell which numbers are complex numbers.
I will however explain what complex numbers look like, which will help you in determining which numbers are complex numbers, and the rest are real numbers.
Step-by-step explanation:
Complex numbers are numbers that include the square root of a negative number.
It is not possible to have a value for an expression with a square root of a negative number, then the letter j or i were introduced to help represent these kinds numbers.
√-1 = i or j (anyone is fine)
Knowing the square root of -1 is i, we can write the square root of any negative number with ease.
√(-6) = √(-1) × √6, right?
= i × √6
= i√6
And so on.
So, basically, the numbers that include the letter 'i', or √(-1) in them are the complex numbers. The rest are real numbers.
