15x + 7
Step-by-step explanation:
x + (7 + 14x)
x + 7 + 14x
15x + 7


Therefore, the man is shorter than 141 centimeters.
Answer:
B. Parallel
Step-by-step explanation:
Equation 1 simplified: y = 3x+7
Equation 2 simplified: y = -x/3-3
The slopes are completely different, ruling out the possibility of the lines being parallel.
But we also see the slopes of the equations are opposite and negative to each other. Making the lines perpendicular.
We use quadratic formula for that one
remember that √-1=i
so
for
ax^2+bx+c=0

so
given
5x^2-6x+2=0
a=5
b=-6
c=2
