First, you need to collect the like terms; 7x + (-20 - 90). Next simplify; 7x - 110
answer; 7x - 110
Answer:
y intercept: 250
slope: -10/3
Step-by-step explanation:
y intercept is where x = 0
slope is found by using the equation (y2 - y1) / (x2 - x1) = (200 - 250) / (15-0) = -50 / 15 = -10 / 3
Standard form:6x^3+x^2-6x+1
The degree is 3
Assume the number 100. 100*1.09=109. You then do 109*0.86=93.74.
So the overall decrease is 6.26%.
