Answer:
Step-by-step explanation:
1) 7x^2-5x+10x-8x=7x^2+5x-8x=7x^2-3x
2) -6a^3+5a^3+2a-a=-a^3+2a-a=-a^3+a
3) -4(x+5)-5(x-1)=-4x-20-5x+5=-9x-20+5=-9x-15
4) -a+5b-6a+5(a+1)=-7a+5b+5a+5=-2a+5b+5
5) 18x^4-3x^3-2x^3+x^2-10+6
=18x^4-5x^3+x^2-4
Dave + 6 friends = 7 friends in total
84 ÷ 7 = 12
Each friend paid $12
can u speak English I would love to help but I don't understand
Using y = mx + c
slope = -17+5/3-1 = -12/2 = -6
Using point (1 , - 5)
y + 5 = -6(x - 1)
y + 5 = - 6x + 6
y = - 6x + 6 - 5
y = - 6x + 1
Hope this helps.
