Because it’s important to know the equation so that would be easy to know the quadratic formula and easy to solve the problem
6.75 + 3x/8 = 13.25
3x/8 =13.25 - 6.75
3x/8 = 6.5
3X = 6.5 x 8
3x = 52
x= 52/3
So your answer would be 52/3 :)
Answer:
0.021/yr or 2.1%/yr
Step-by-step explanation:
Find the quotient:
$36.75/$36.00
This comes out to 1.021,
so the inflation rate is 1.021 - 1.000 = 0.021 or 2.1%/year
Answer:
f(x) = 4/7x + 20/7
Step-by-step explanation:
If we were to graph this function, we would see that the two points would be, (-5, 0), and (2, 4). First, we have to find the slope, which is equal to:
<u>(first y-coordinate - the second y coordinate)</u>
(first x-coordinate - second x coordinate)
= <u>(0 - 4)</u>
(-5 - 2)
= -4/-7 = 4/7. now, we multiple -5 by 4/7 and get -20/7. we have to add 20/7.
Thus, the answer is f(x) = 4/7x + 20/7
