i’ll give you all my points that i have and rate you good if you answer these three questions before 3:00pm est. if f(x)=8-5x, find each value. one is f(4c), the second question is f(2-k), and the third is f(4p+3)
Ok so to start you plug in what’s in the parentheses for x
4c=8-5(4c) 2-k=8-5(2-k) 4p+3=8-5(4p+3)
In the first one you distribute the -5 4c=8-20c Then add 20c to both sides 24c=8 And divide by 24 C=8/24 or 1/3
Distributing the -5 on the second one gets you 2-k=8-10+5k Then you combine like terms 2-k=-2+5k Subtract 5k from both sides 2-6k=-2 Subtract 2 from both sides -6k=-4 Divide by -6 K=4/6 or 2/3
and lastly the equation is 4p+3=8-5(4p+3)
So you distribute -5 4p+3=8-20p-15 Combine like terms 4p+3=-20p-7 Add 20p to both sides 24p+3=-7 Subtract 3 from both sides 24p=-10 And then divide by 24 P= -10/24 or -5/12
