Please help im desperate if f(x) = 5 + 3x find the value of the dependent variable if the if he independent variable is -4 and if you know hoew to do this pls answer my other question

the dependent variable is -7

Step-by-step explanation:

this is really simple all we have to do is plug -4 instead of x

so the equation is going to be f(-4)=5+3(-4)

now we just solve like normal so that would be...

f(-4)= 5+ -12 (3*-4 is -12)

f(-4)= -7

i hope it helps

answer: -0.5 would be the most likley outcome

step-by-step explanation:

55.44 inches

step-by-step explanation:

part a. assuming a perfectly linear relationship, we can find the slope from the first two data points.

slope = m = (change in rainfall)/(change in years)

= (61.80 -62.33)/(2005 -2004) = -0.53/1 = -0.53

then the point-slope form of the equation of the line can be written as

y = m(x -h) +k . . . . . m = -0.53, (h, k) = (0, 62.33)

y = -0.53x +62.33 . . . x = years after 2004

part b. in 2017, x = 2017 -2004 = 13. then the predicted rainfall is

y = -0.53·13 +62.33 = 55.44 . . inches

the predicted rainfall in 2017 is 55.44 in.
