Response:
Her brother catches up to her at 11 am + 4 hours = 15 p.m
Detailed explanation:
Provided information;
Ariel's speed = 45 mph
She departed at 9 a.m
Her brother's speed = 60 mph
He began at 11 a.m
Inferred from the question: Since Ariel's speed is 45 mph, after two hours she is ahead by 90 miles.
Meanwhile, her brother travels at 60 mph, hence he is traveling (60 - 45) = 15 mph faster
Therefore, with this speed, he will catch up to her in
= 4 hours.
So her brother catches up with her at 11 am + 4 hours = 15 p.m
Answer:
Hours
Step-by-step explanation:
This is an incorrect figure.
Answer:
The constant pay of $25 signifies the intercept
Step-by-step explanation:
To address this query, we first need to comprehend and relate it to the formula for a straight line.
i.e
this represents the line's equation
where m= slope
y= dependent variable
x= independent variable
c= intercept
Given

by comparing the two expressions, we can observe that
25 is equivalent to c, which denotes the intercept
BD=7x-10
Solution: x=bd/7 + 10/7
BC=4x-29
Solution: x=Bc/4 + 29/4
CD=5x - 9
Solution: x= cd/5 + 9/5
