Answer:
the must be 3 it couldn't be 10-x.
Answer:
The system of equations is not independent (i.e. dependent)
Step-by-step explanation:
We see that in the system of equations
3x + 6y = 12 ............(1)
x + 2y = 4.................(2)
equation (1) is exactly the same as 3 times of equation (2).
When graphed, both lines will coincide.
Therefore the system of equations is not independent (i.e. dependent)
Answer:
135=15m+25 OR 15m+25=135
Step-by-step explanation:
To set this equation up you want to look at key words. It states that "Karina now saved $135" in meaning her total saved. Now it states she STARTED the account with 25 so that would be added to the amount she adds per month (which is $15). The equation can be set up as 15m+25=135. 15m because m stands for every month she added $15, 25 because she started the account with 25 and 135 because that's her total after the several months.
Answer:
y = -5/4x - 8
Step-by-step explanation:
Slope = m = -5/4
y = -5/4x + c (or b, depending on where you're from)
You can sub (-8, 2) and (-4, -3) into y = -5/4x - c and both are the same to where c = -8
Therefore, the equation is = y = -5/4x + (- 8)
= y = -5/4x - 8
Hope this helps
