Using the laws of indices, you can solve it.
Answer:
f= 5x
Step-by-step explanation:
x is the amount of food you want over 5 years so you would have to times it to get the whole amount eaten after 5 years.
To factor: Notice that when you factor it should turn out to be a binomial x binomial.
x^2-10x+25
When factoring you can look at the operation at the end right before the last digit. If the operation is positive then you will use the first operation in the binomial for factored number. For example the ending operation is positive and the first operation is subtraction so both binomial will be subtraction.
I know it would be factored (x-5)(x-5) and I can prove it by multiplying it out.
x^2 -5x-5x+25
x^2-10x+25
19. 19.31 times 40=$772.4
20. 52 times 772.4=$40,164.8
weekly = 40 times 19.31
yearly =weekly times 52 or 19.31 times 40 times 52
21. 15.07 times 40=$602.8
22. 52 times 602.8=$31,345.6
weekly = 40 times 19.31
yearly =weekly times 52 or 15.07 times 40 times 52
23. Monica yearly-Chris yearly=40,164.8-31,345.6=$8816.2
Answer:
18
Step-by-step explanation:
f(2)=4x+10
f=(4)(2)+10
f=8+10
f=18
