Answer:
4 months and you can check for yourself by plugin in 4 in both equations (e.g. 1(4)+16=4(4)+4
Step-by-step explanation:
To do this: Agora = 1x+16
Key Club = 4x+4
1x+16=4x+4
1x+12=4x
12=3x
4=x
I have a lot to say about the
The sale price was 30% off the original price, which means it was on sale for 70% of the original cost ( 100% - 30% = 70%)
To find the original cost, divide the sale price by the percent of the original cost:
21 / 0.70 = 30
The original price was $30
check:
30 x 0.3 = 9 ( amount of discount)
30 - 9 = 21 ( sale price)
Câu trả lời:
0,7
Giải thích từng bước:
Xác suất để một sự kiện xảy ra = 0,3
Cho sự kiện = A
P (A) = 0,3
Xác suất mà sự kiện không xảy ra có thể thu được bằng cách sử dụng quy tắc bổ sung;
P (A ') = 1 - P (A)
Vì thế,
P (A ') = 1 - 0,3 = 0,7
Answer:
slope of line (m) : 3
Step-by-step explanation:
P1: (-2 , -2)
P2: ( 1, 7)
the slope formula is
m = ( Y2-y1)/(x2-x1)
m = (-2-7)/(1+3)
m=3
Equation of line is y=mx+b
Using P2 ( 1,7)
7 = 3(1) + b
7 = 3+ b
7-3 = b
b = 4
so that, line equation is:
y = 3x +4
