Answer:
Step-by-step explanation:
3a^4 -2a^2 + 5 - 10 -(2a^4 +4a^2 + 5a -2)
as given.. i'm wondering if the 5 in the first group is really 5a.. hmmm
I'm guessing that it is... soooo distribute the minus sign
= 3a^4 - 2a^2 +5a -10 -2a^4 -4a^2 -5a +2
= a^4 -6a^2 -8 :) voila that's your answer
Answer:
Option C: $30 is the original price of book.
Step-by-step explanation:
Let the original price of book be x
Given that:
Sale price = x - 40% of x
As it is given that the sale price was $18
So,
$18 = x - 40% of x
By simplifying:
$18 = x - 0.4x
$18 = 0.6x
Dividing both sides by 0.6:
x = $18/0.6
x = $ 30
So the original price of book will be $30
i hope it will help you!
Answer:
y = - x + - 2
Step-by-step explanation:
Using the equation y = mx + b, find the m (slope) from the graph and the b (y-intercept from the graph). The slope, m, is the rise over the run from point A to point B. The rise is -5 and the run is 5.
= -1. The y-intercept, b, is the point the graph passes through the y-axis. The b is -2 so y = -x+-2.
