The mistake is there is no parenthesis around 4x+12
X-intercept => 2x = 6 => x = 3
x-intercept is 3.
y-intercept => 3/2y = 6 => y = 4
y-intercept is 4.
z-intercept => 3z = 6 => z = 2
z-intercept is 2.
Step-by-step explanation:
As all angles in a triangle add up to 180°
we can write:
(m+18)+(2m+28)+(3m+47) = 180
6m + 93 = 180
6m = 180 - 93
6m = 87
m = 87 / 6
m = 14.5
Answer:
y = 5x + 3 is a nonproportional relationship.
Step-by-step explanation:
We need to find the equation that represents a nonproportional relationship.
If y is directly proportional to x, it would mean that,
y ∝ x
y = kx
Option (b) shows the equation of a line i.e. y=mx+x, where m is slope and x is y-intercept.
Hence, we can say that option (b) represents a nonproportional relationship.
