Mrs. Castro left her parents' house in the province and drove home.
After driving for 3 hours, she was 90 km from home, and after
5 hours, she was 25 km from home. Assuming that the distance from
home and the number of hours driving form a linear relationship,
how long did it take Mrs, Castro to drive from her parents' house
to her home? How far was Mrs, Castro from home after driving
6 hours? How long had Mrs. Castro been driving when she was
50 km from home?
Answer:
Distance problems are word problems that involve the distance an object will travel at a certain average rate for a given period of time.
The formula for distance problems is: distance = rate × time or d = r × t.

In evaluating the limits of rational functions, the numerator and the denominator was found out to be both equal to zero, what does it mean?
Answer:
If only numerator found as zero the answer would be zero. If only denominator found as zero the answer is undefined. In your situation both are zero. But, when denominator becomes zero the answer always be undefined. Therefore, your answer is undefined when both numerator and denominator are zeros.

Which could be used to evaluate the expression -6(4 2/3)?
Answer:
The answer is A
-6[4 2/3]
= -6[4+2/3] because 4 2/3 is 4 and 2/3rds
so a(b+c) = a(b) + a(c)
so -6(4) + -6(2/3)

a air balloon is at a height of 2,520 feet. it begins to descend at the rate of 140 feet per minute.
1.Write an expression to model its height after x minutes
2. Find the expression for 2,5,8,10,15 minutes
Answer:
2,520 - 140x
2,520 - 140(2) = 2,240
2,520 - 140(5) = 820
(etc etc)
Step-by-step explanation:
This equation can handle any numbers.
Answer:
1. 2520 - 140x
Add up the minutes
2+5+8+10+15=40
Subsitute x for 40 minutes.
2. 2520 - 140(40)
I hope this makes sense!

Find two numbers whose product is -6 and whose sum is 1.
Answer:
-2, 3
Step-by-step explanation:
yeah that's it I don't have any explanation or formula
let the numbers be x and y
xy = -6
x + y = 1
from x + y = 1
y = 1 - x
x(1 - x) = -6
x - x² + 6 = 0
-x² + x + 6 = 0
on solving,
x = -2 or x = 3
y = 1 - (-2) = 3
y = 1 - 3 = -2
x1 = -2, y1 = 3.
x2 = 3, y2 = -2.

A little boy accidentally let go of his balloon, and it floated away. It was 3 feet above the ground when he let go, and it steadily rose 3 feet per second. Write an equation that shows the relationship between the number of seconds since the boy let the balloon go, x, and its elevation in feet, y.
The equation that shows the relationship between the number of seconds since the boy let the balloon go is y = 3x + 3.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A little boy accidentally let go of his balloon, and it floated away. It was 3 feet above the ground when he let go this height is our constant value in the function.
It steadily rose 3 feet per second.
Assuming time in seconds to be x and total height is y.
∴ An equation that shows the relationship between the number of seconds since the boy let the balloon go is,
y = 3x + 3.
