- Revathi's age is 1/3 of her mother's age. If their difference in age is 24 years, find Revathi's age.
Given,
- Mother's age = x
- Revathi's age = 1/3 x = ?
- Difference in their age = 24 years ⇨ x - 1/3 x = 24.
Now, let's solve this question using the above equation which we just formed.
Combine x and 
to get 
.
Multiply both sides by 
, the reciprocal of 
.
Express 
as a single fraction.
Multiply 24 and 3 to get 72.
Divide 72 by 2 to get 36.
We now have the age of Revathi's mother (x) = <u>36 years</u>. Now, let's find Revathi's age ⇨ 
- So, Revathi is <em><u>1</u></em><em><u>2</u></em><em><u> </u></em><em><u>years </u></em><em><u>old.</u></em>
Given:
The graph of a parabola.
To find:
The domain, range and check whether it is a function or not.
Solution:
Domain: The set of x-values or input values is known as domain.
Range: The set of y-values or output values is known as range.
A relation is a function if their exist unique outputs for each input. In other words a graph is a relation if it pass the vertical line test.
Vertical line test: Each vertical line intersect the graph at most once.
The given function is defined for all real values of x which are greater than or equal to -3. So, the domain of the given graph is:
The given function values can be any real number. So, the range of the given graph is:
For x=0, we have two values of the function because the graph intercept the y-axis at two points.
Since the graph does not pass the vertical line test therefore the given graph is not a function.
Answer:
$200
Step-by-step explanation:
Fine calculated per mile = $10
Fine calculated for 'm' mile = 10 * m = 10m
Cost paid by violator = 80 + 10m
m = 12 miles
Cost paid by the violator = 80 + 10*12
= 80 + 120
= $ 200
Answer:
y= 3/2x- 4
Step-by-step explanation:
3/2 = mx
b= -4
y=mx+b
So the correct ratio is 4:5
The only one that doesn’t mean the same as that is C.
