Answer:
6. 3x^3-7x^2+4x-1
7. -6x^4-2x^2+6x+10
8. 42x^4
Step-by-step explanation:
Answer: Addition Property of Equality
We add 7 to both sides to go from 19 = 2x-7 to 26 = 2x
Round 396.6 to 396, because 396/9=44, making a whole number. Hope this helps!!
Multiply by 4 to get rid of fraction
4(18) = 4(x/4 + 7)
72 = x + 28
x = 44
Solution; x = 44
Answer:
y = -1/4x + 7
Step-by-step explanation:
Plug in the point and slope into y = mx + b, and solve for b:
y = mx + b
8 = -1/4(-4) + b
8 = 1 + b
7 = b
Plug in the slope and b into y = mx + b:
y = mx + b
y = -1/4x + 7
So, the equation of the line is y = -1/4x + 7
