You can try to use the points: (3, 3) and (-3, -1)
if you plug the values listed above using the slope formula : y2 - y1/x2 - x1
you should get the answer: - 4/6 which is simplified to 2/3
hope this helps :)
Answer:
Step-by-step explanation:
I take it that the expression is
Collect like terms and add the coefficients
Coefficients are y and x
Variables are the number with the letters
The terms are the numbers
Answer = $39.78
100-20 =80
100-25=75
Multiply 60 x .80 to get $48
Then multiply 48 x .75 to get $36
Sales tax %10.5 = move decimal two places to left .105
Now multiply 36 x .105 =3.78
$3.78 equals your sales tax
Finally add $3.78+$36= $39.78
P=1
p^4+p^2+p-k=0
1+1+1-k=0 k=3
