Answer:
45,78%
Step-by-step explanation:
42 + 67 = 109
109 x 42 / 100 = 45,78 %
if we take 6 to be the 100%, what is 8 off of it in percentage?

Answer:
Because we have a point and slope, we can use at the beginning the point-slope form: y-y1=m(x-x1)
Step-by-step explanation:
m=3 , x1=1 , y=-3
y-(-3)=3(x-1)
y+3=3x-3 subtract 3 from both sides
y=3x-6 the answer in the slope-intercept form y=mx+b
This is a famous triangle ( 5 -12 -13)
So y1= -7
