Answer:
- Distance in 47 minutes = 0.75 × 47 = 35.25 miles
- Distance in 1 hour or (60 minutes) = 0.75 × 60 = 45 miles
Step-by-step explanation:
Given that the car is traveling at a steady speed.
Distance traveled in 2 1/3 or 7/3 or (2.33) minutes = 1 3/4 miles
= 7/4 or 1.75 miles
Thus,
distance in 1 minute: 1.75/2.33 = 0.75 miles per minute
Thus,
- Distance in 47 minutes = 0.75 × 47 = 35.25 miles
- Distance in 1 hour or (60 minutes) = 0.75 × 60 = 45 miles
Well, it’s quite surprising to learn that washing and drying may take up to 80 minutes.

Answer:
- f(-2) = 4
- f(1) = -5
- D: [-3, ∞)
- R: [-5, 11]
Step-by-step explanation:
You have marked the points on the graph corresponding to ...
f(-2) = 4
f(1) = -5
__
The domain is the horizontal extent, from x = -3 to +∞.
The range is the vertical extent, from y = -5 to +11 (inclusive).
You can find counterexamples to disprove this claim. We have positive integers that are perfect square numbers; when we take the square root of those numbers, we get an integer.
For example, the square root of 1 is 1, which is an integer. So if y = 1, then the denominator becomes an integer and thus we get a quotient of two integers (since x is also defined to be an integer), the definition of a rational number.
Example: x = 2, y = 1 ends up with
which is rational. This goes against the claim that
is always irrational for positive integers x and y.
Any integer y that is a perfect square will work to disprove this claim, e.g. y = 1, y = 4, y= 9, y = 16. So it is not always irrational.
TSR because if u look at the lines of where their similar on the second one you match it up
