Answer:
The simplified equation is as follows 2x^5 -x^4 + 9x^2
Step-by-step explanation:
Remove the parentheses around each equation and pair like exponents together
4x^5 - 2x^5 - x^4 + 3x^2 + 6x^2
Then combine the like terms
2x^5 - x^4 + 9x^2
It is in that order due to the proper form being to go from the highest to lowest exponents in an answer
25% of $80=$20
$80-$20=$60 remaining after you purchased shorts
65% of %60=$39
Answer: Sandals cost $39.00
You first need to cross multiply to get 8x+8=6x^2-6. Then make the function into 6x^2-8x-14=0 which can be simplified into 3x^2-4x-7=0 by dividing the equation by 2. Then you must split the middle(-4x) to get 3x^2+3x-7x-7=0. This simplifies to 3x(x+1)-7(x+1)=0 and then to (3x-7)(x+1)=0. From here you just solve for each root which you will find are x= -1 and 7/3
(a) y = 2x + 3
(b) (1,5), (3,3); y = 3x + 3 5 = m1 + b, 3 = m3 + b
(c) coincident i believe, because it is not independent or inconsistent
(d) 2x + 3 = 3x + 3
(-2x)(-3) (-2x)(- 3)
0 = -2x
x = 0
hope this helps
