B. (x - 3)
Odd integers are 2 apart
they are n, n+2, n+4
the sum is 75
n+n+2+n+4=75
3n+6=75
minus 6 both sides
3n=69
divide both sides by 3
n=23
n+2=25
n+4=27
the integers are 23,25,27
Answer:
y = - 3/2x - 4
Step-by-step explanation:
m = - 3/2 ( use the opposite reciprocal of the slope given) Perpendicula lines have opposite reciprocal slope
2. Find b by plugging in the m and one of the points given into y = mx + b
5= - 3/2 ( - 6 ) + b
5 = 9 + b
- 4= b
3. Write the equation using the m and the b you just found
y = - 3/2x - 4
