Work:
1) 11y - 3 = 13x
2) 11y = 13x + 3
3) y = 13/11x + 3/11
Answer: f(3) = 14
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
<u>Given function</u>
f(x) = 4x + 2
<u>Substitute value of the x into the expression</u>
f(3) = 4(3) + 2
<u>Simplify by multiplication</u>
f(3) = 12 + 2
<u>Simplify by addition</u>
f(3) = 
Hope this helps!! :)
Please let me know if you have any questions
Answer:x = 6.5
Step-by-step explanation: Subtract 5 from both sides and you get 1/2x=13 then isolate the x by dividing both sides by 1/2 to get x=6.5.
A fraction and a percentages are equivalent.
30 out of 60
= 30/60
= 3/6
= 1/2
but especially:
= 50/100
which means:
50 out of 100
or
= 50%
