Answer:
exactly one
Step-by-step explanation:
The system of linear equations have:
one solution, infinitely many solutions or no solution.
One solution if the lines intersect.
Infinitely many solutions if the lines are the same (overlap)
There is no solution if the lines are parallel (they do not have a common point).
In the graph, two lines intersect. Therefore, the system of equations has one solution (0, 3).
B - 4 >_ 0
b >_ 4
-3b + 5 > 8
-3b > 3
b> -1
Answer:
y = 2/5x + 1/5
Step-by-step explanation:
First, plug in the slope.
y = mx+b
y = 2/5x + b
Then, plug in the point given, in order to find b.
-1 = 2/5(-3) + b
-1 = -6/5 + b
1/5 = b
So the final equation is:
y = 2/5x + 1/5
<h2>
Answer with explanation:</h2>
The formula to calculate the compound amount is given by :-
, where P is the Principal amount invested , r is the rate of interest ( in decimal ), and t is the time period ( in years).
As per given , we have
P= $500 , r= 6%=0.06
Then the formula to find the compound amount after t years :
(Put values of P and r in the formula)
For t=1
Jack will have $530 after 1 year.
For t=2
Jack will have $561.8 after 2 years.
For t=5
Jack will have $669.11 after 5 years.
For t=10
Jack will have $895.42 after 10 years.
14:1 can also be written as 14 to 1 and 14/1. Aka 14/1 is in fraction form not division.
