27.7 cm
Step-by-step explanation:
(12,45cm + 2.8cm)=(belinda's shoe+felix added cm)= felix's shoe
12,45cm= belinda shoe
combined lenght = 12,45+ 15,25=27.7 cm
Answer: -1 and 4
Explanation: the others aren’t because they have variables in one and numbers in the other
Answer:
The answer to your question is: y = -1/2 x + 3
Step-by-step explanation:
Data
slope = m = 2
y-intercept = 3
line l is ⊥
Process
1.- Calculate the slope of line l
l = - 1/ m
l = - 1 / 2
(m)(l) = (2)(-1/2)
= -1 As m x l is "-1" the lines are perpendicular
2.- Find the line of line l
Equation y - y1 = m (x - x1)
Point (0, 3)
y - 3 = - 1/2 (x - 0) Substitution
y - 3 = -1/2 x Simplification
y = -1/2 x + 3
