Given:
For a function f,
.
To find:
The coordinates of a point on the graph of f.
Solution:
We have,

It means the value of function f is 10 at -4.
On a coordinate plane x-axis represents the input values and y-axis represents the output values of a function. So,
x-coordinate = input value = -4
y-coordinate = output value = 10
Therefore, the required coordinates of a point on the graph of f are (-4,10).
Step 1: 1/10 + 1/10 = 2/10
Step 2: 4/5 - 2/10
GCF: multiply both sides of 4/5 by 2 = 8/10
Step 3: 8/10 - 2-10 = 6/10
ANSWER: C <span>fraction 6 over 10, because fraction 4 over 5 minus 2 times fraction 1 over 10 equals fraction 4 over 5 minus fraction 2 over 10 </span>
Answer:
40%
Step-by-step explanation:
In order to find percent, you can set up the fraction 2/5 to the equation x/100.

Then solve using algebra to cross-multiply.



so the answer is 40%.
To find his age 4 years ago, you need to subtract 4 from his current age.
His current age is Y, so his age 4 years ago is: y - 4
