2.)
0 = 6x + 3y +9
-3y = 6x + 3y - 3y +9

By isolating y we now have the equation in slope intercept form:

Where m = slope and b = y- intercept. Therefore, the slope is -2 and the y - intercept is -3.
4.)
Similarly, #4 is already in slope intercept form so we can solve it by inspection. So for #4 the slope is -1 and the y - intercept is 2.
Answer:
No
Step-by-step explanation:
the first one would be 65 and 23/1000, while the other one is 65 and 23/100
I would go about solving this by elimination because the x variables are already the same so all you would have to do is change one equation to the opposite signs and add them, so it would look like:
7y + 5x = 19
+ -3y - 5x = -7
-------------------
4y=12
y=3
Answer:
9.3%
Step-by-step explanation:
Given data
Principal=$11200
Futute value= $14345
Time= 3years
The simple interest expression is given as
A=P(1+rt)
substitute
14345=11200 (1+r*3)
14345=11200+r33600
14345-11200=r33600
3145=r33600
r= 3145/33600
r=0.093
Hence the rate is 9.3%
