Put 3x + 3y = 45 in slope intercept form
y = 15 - 3/3x
(-3/3x is just going to simplify to -1x though)
Perpendicular form of -1x would be 1x
So your perpendicular slope would be 1
Answer:
C
Step-by-step explanation:
a = 1
b = -5
c = 3
(-b ± √b² - 4ac) ÷ 2a
[5 ± √25 - 4(3)] ÷ 2
(5 ± √13) / 2
Answer:
Step-by-step explanation:
250 x 34%
250 x 34/100
25 x 34/10
5 x 34/2
5 x 7
35
Answer:
Step-by-step explanation:
Carly : y = 60x + 40
janiya : y = 50x + 80
60x + 40 = 50x + 80
60x - 50x = 80 - 40
10x = 40
x = 40/10
x = 4 <=== so at 4 weeks, they will have the same amount of money <==
The money they have is : y = 60(4) + 40.....y = $ 280 <=
so ur answer is : 4 weeks, $ 280
