Answer:
Linear function: y = -15x + 75
Domain: x ≤ 5
Range: y ≥ 0
Please tell me if there are any mistakes in my answer and I will correct them.
Step-by-step explanation:
The linear function is y = -15x + 75, written in y=mx+b form. X is the amount of hours. Since the speed is decreasing, we will use -15. Since we started at 75 miles per hour, our b value will be 75.
DomainThe domain is all the possible values for x.
Since the comet slows down by 15 miles every hour until it stops moving, we can solve for x by putting in 0 for y.
0 = -15x + 75
15x = 75
x = 5
Therefore, the domain is x ≤ 5.
RangeThe range is the set of all possible values of y. In this case, the range can be anything but 0 in order for the equation to make sense.
So, the range is y ≥ 0.
Answer:
domain is 0,5
Step-by-step explanation:
after 5 hours, it stops moving
3+(-7) +(-6) add the following integers
Answer:
-10
Step-by-step explanation:
expand: 3-7-6=-10
note smaller positive number minus bigger number makes negative answer, e.g 7-8= -1
The answer is:
-10Work/explanation:
Use the integer rule:
[tex]\rhd\quad\sf{a+(-b)=a-b}[/tex]
___
[tex]\rhd\quad{\sf{3+(-7)=3-7=-4}[/tex]
[tex]\rhd\quad\sf{-4+(-6)=-4-6=-10}[/tex]
Hence, the answer is -10.

| -16+51 | absolute value
Answer: 35.
Step-by-step explanation:
The absolute value of a number is the non-negative value of the number without regard to its sign. It may be thought of as the distance of the number from zero on a number line. It is symbolized by two vertical lines, as |3| or |−3| is equal to 3. For complex numbers, the absolute value is the positive square root of the sum of the squares of the real and imaginary parts. The absolute value is used to determine the numeric value of a quantity, irrespective of sign, that has no meaning for the sign.
To find the absolute value of -16+51, you need to simplify the expression first and then apply the definition of absolute value. -16+51 = 35, so | -16+51 | = | 35 |. Since 35 is a positive number, its absolute value is itself. Therefore, | -16+51 | = 35.

The simplified form of [tex]\frac{\sqrt[3]{81} }{\sqrt[3]{-3} }[/tex]
Answer:
-3
Step-by-step explanation:
[tex]\frac{\sqrt[3]{81} }{\sqrt[3]{-3}}\\[/tex]
the index of both the numerator and denominator are "3", so they cancel each other out:
[tex]\frac{\sqrt{81} }{\sqrt{-3}} \\=\frac{9}{-3}\\ =-3[/tex]
