Can someone explain to me I’m confused

Step-by-step explanation:

Here you have the function f(x) = 3x + 5 and are being asked to 'evaluate' it at x = {-1,0, 2, 4}.

Arbitrarily starting out with x = 0, we get f(0) = 3(0) + 5 = 5

Next,

f(-1) = 3(-1) + 5 = 2

f(2) = 3(2) + 5 = 11

and, finally, f(4) = 3(4) + 5 = 17

so the right hand column for this function (which are function values) is

2

5

11

17

and in set format this is {2, 5, 11, 17}

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
