With the given data, the first step to take is to use MS excel to plot the data then determine the trendline in which the equation's r2 value is closest to 1. From the plot obtained from Excel, the plot is a second degree polynomial and not an exponential function. the answer hence is no.
Answer:
y=5x-2
Step-by-step explanation:
5*-2=-10 -10-2=-12
5*-1=-5 -5-2=-7
5*0=0 0-2=-2
5*1=5 5-2=3
5*2=10 10-2=8
Answer:
b = - 21
Step-by-step explanation:
calculate m using the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (- 6, 3)
m = 
= 
= - 4
y = - 4x + b ← is the partial equation
to find b substitute either of the 2 given points into the partial equation
using (- 4, - 5 ), then
- 5 = 16 + b ⇒ b = - 5 - 16 = - 21
Answer:
$11.63
Step-by-step explanation:
3 packs of pens x $3.59 = $10.77 worth of pens
To find the tax--> 8%= 0.08
0.08 x 10.77= 0.8616
0.86.16+ 10.77= $11.6316
Rounded to the nearest 10th is $11.60
