The equation is y=1.55X+110,419 and they give you X so put that in: y=1.55(78,300)+110,419.
Now you multiply: 1.55(78,300)=121,365, y=121,365+110,419.
Now add: 121,365+110,419=231,784 :)
Answer: -3
Explanation: In this problem, we're given the function f(x) = 2x + 1 and we're asked to find f(-2).
To find f(-2) or the value of the function or the value of the function when <em>x = -2</em>, we simply substitute -2 in for <em>x</em> in our function.
So we have f(-2) = 2(-2) + 1 or -4 + 1 which equals -3.
So f(-2) or the value of the function when x = -3 is -3.
34 kg = 5.3 stones
34 x 2.2 = 74.8 / 14 = 5.34
