Answer:
-5
Step-by-step explanation:
First, put the equation into the form y = mx +b (where m is the slope and b is the y-intercept)
This would look like:
![5x + y = 3\\y = -5x + 3](https://tex.z-dn.net/?f=5x%20%2B%20y%20%3D%203%5C%5Cy%20%3D%20-5x%20%2B%203)
This means the slope is -5.
Parallel lines always have the same slope, so the slope of the parallel line is also -5
The answer would be 56.10
Answer:
a = 10
Step-by-step explanation:
Since the quantities vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the point (2, 5 ) with x = 2 and y = 5
k =
=
= 2.5
y = 2.5x ← equation of variation
Using the point (4, a) with x = 4, then
y = a = 2.5 × 4 = 10
Simple interest uses the equation/formula A=P( 1 + RT) where A = the amount after T years, T = the number of years, R = the interest rate, and P = Principal amount of what you started with. "65 hundred" = 6500
Just plug in to get 6500 = 5000(1 + 15R). Distribute to get 6500 = 5000 + 75000R. Subtract 5000 both sides then divide by 75000 to isolate the R.
You get 1500/75000 = R. R = 0.02 or 2%
The interest rate is 2%
