R1 ÷ 2 =
R2 ÷ -5 =
R2: R1 - R2 =
R2 ÷ 3.2 =
R1: R1 - 3R2 =
Answer: x = 0.65625, y = 0.71875
slope = (y2-y1)/(x2-x1)
= (70-52)/(8-1)
= 18/7
=2.6
point slope form
y-y1 = m(x-x1)
y-52 = 2.6(x-1)
distribute
y-52 = 2.6x-2.6
add 52 to each side
y = 2.6x+49.4
y = 2.6x +49
the initial temperature is 49.4 or about 49
and it increases about 2.6 degrees each week
The solution possible can be correct by dividing both sides by -5 ;Sooo x>-5.....
I think it’s C i think is right
