I hope that's right I'm not too sure lol
Answer: m= 1/420
Step-by-step explanation:
5x + 6y - 6y - 425x = 42
5x -425x = 42
0 = -420x - 42
m = -420
slope of a perpendicular line = 1/420
if that helps.
A) (8-8/6-2)=0
B) (3-4/7-3)= -1/4
C) (9-3/6-2)=3/2
D) (5-3/7-7)= 1/0 (not identified)
Answer:
7 : 5
Step-by-step explanation:
let the age of the younger be x , then the older is x + 18, thus
x + x + 18 = 108, that is
2x + 18 = 108 ( subtract 18 from both sides )
2x = 90 ( divide both sides by 2 )
x = 45
Thus younger is 45 and older is 45 + 18 = 63
ratio older : younger = 63 : 45 = 7 : 5
<h3>Given</h3>
The current balance is $420.
The current balance is 7/6 of the original balance, b
<h3>Find</h3>
equation to use to find b
<h3>Solution</h3>
Equate the two descriptions of the current balance.
... $420 = (7/6)b . . . . . equation to use to find b
