X = 1/cos(30)
X = 1.154700538
X = 1.2 (nearest tenth)
The blue ribbon would be 19 inches. We know the red ribbon is 12 inches and it’s 7 inches less than the blue one, so you would add 7 to 12 to figure out that the blue ribbon is 19 inches.
A proportional relationship is between two variables where their ratios are equivalent. Another way to explain is one variable is always a constant value times the other . Which is known as the “constant proportionality”
This is point slope form so you start with
y-b = m(x-a)
then you would find a point (5, - 1)
then fill in
y-5 = 3(x-1)
then if you want solve it for slope intercept form
y = 3x + 2
graph that and check your work
