Answer:
increase, decrease
Step-by-step explanation:
Since you multiply x by 4, it should get bigger if it is positive. Multiplying y by .88 makes it smaller because it is less than 1.
A perfect square is when a trinomial can be factored into a binomial multiplied by itself right? If that's the case then I think b=8
x^2-8x+16
x^2-2×x×4+4^2
(x-4)^2
For these, we just have to expand then collect like terms.
1) 4x^+2x+4x+2 ~ 4x^+6x+2
2) 6x^+12x+2x+4 ~ 6x^+14x+4
3) 6x^+12x+3x+6 ~ 6x^+15x+6
4) 5x^+5x+2x+2 ~ 5x^+7x+2
Hope these help, have a great day
It is not provable because both sides are not equivalent.
Answer:
y=-5/4x+3
Step-by-step explanation:
y=mx+c
m = (y1-y2)/(x1-x2) =(-2-3)/(4-0) =-5/4
sub the values y=3, x=0 to find c,
3 =-5/4(0) + c
c = 3
