Answer:
<h2>f(-3) = 22</h2>
Step-by-step explanation:
f(x)=x² - 2x + 7
To find f(-3) substitute the value of x that's - 3 into f(x). That is for every x in f (x) replace it with - 3
We have
f(-3) = (-3)² - 2(-3) + 7
= 9 + 6 + 7
We have the final answer as
f(-3) = 22
Hope this helps you
As with any "solve for" problem, you undo what has been done to the variable, in reverse order.
Subtract 9, divide by 3, take the 5/3 power
.. 3*(a +4)^(3/5) +9 = 36 . . . . . original equation
.. 3*(a +4)^(3/5) = 27
.. (a +4)^(3/5) = 9
.. a +4 = 9^(5/3)
.. a = 9^(5/3) -4 ≈ 34.9407
<span>All you've got to do is multiply both 13 and 20 by 5 so the fractions would be 65/100. Since you're trying to convert it into a decimal, you would move the decimal point 2 units to the right. This will result in the answer : 0.65.</span>
Changing 13/20 into a decimal would be 0.65
