Answer:
x= 8
Step-by-step explanation:
17x + 3 = 139
17x = 136
x = 8

Answer:
(a, b, c) = (-0.425595, 11.7321, 2.16667)
f(x) = -0.425595x² +11.7321x +2.16667
f(1) ≈ 13.5
Step-by-step explanation:
A suitable tool makes short work of this. Most spreadsheets and graphing calculators will do quadratic regression. All you have to do is enter the data and make use of the appropriate built-in functions.
Desmos will do least-squares fitting of almost any function you want to use as a model. It tells you ...
a = -0.425595
b = 11.7321
c = 2.16667
so
f(x) = -0.425595x² +11.7321x +2.16667
and f(1) ≈ 13.5

<em>Additional comment</em>
Note that a quadratic function doesn't model the data very well if you're trying to extrapolate to times outside the original domain.
Answer:
point slope: y-7=2(x-4
slope intercept: y=2x-1
Step-by-step explanation:
point slope form: y-y1=m(x-x1)
(4,7) and m=2
using all the info here is it in point slope form: <u>y-7=2(x-4)</u>
turning the point slope equation into slope intercept...
slope intercept form: y=mx+b
first simplify y-7=2(x-4) into y-7=2x-8
then add 7 to both sides...
which would be <u>y=2x-1 </u>
and thats your answer!!
