Answer:
y-int=(0,40.5), x-int=(-18,0)
Step-by-step explanation: First you need to calculate the slope, which is 9/4. Then plug in a point into the y=mx+b, or slope intercept, equation using that slope.
9=(9/4)x+b. You'll get b is 40.5 which is y-int. Then plug in 0 for y and solve for x, which is your x int coordinate.

Step-by-step explanation:
what i find useful is if you flip the percentage of whatever, it makes it pretty easy. in this situation itd be 50% of 8, which is 4. for the total price, you just add the tax to the price

Answer: 
Step-by-step explanation:
(3x^2+x-1)(x^4-2x+1)
=3x^6-6x^3+3x^2+x^5-2x^2+x-x^4+2x-1
=3x^6+x^5-x^4-6x^3+x^2+3x-1
