Answer: it's x,w I believe
Step-by-step explanation: I'm pretty sure they both have the same vertex
Answer: Option D
Step-by-step explanation:
The equation of the line in slope intercept form is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where m is the slope and b the y-intercept.
Solve for y from both equations:
![5y=-3x+9\\y=\frac{-3}{5}x+\frac{9}{5}](https://tex.z-dn.net/?f=5y%3D-3x%2B9%5C%5Cy%3D%5Cfrac%7B-3%7D%7B5%7Dx%2B%5Cfrac%7B9%7D%7B5%7D)
![5y=-3x+15\\y=\frac{-3}{5}x+3](https://tex.z-dn.net/?f=5y%3D-3x%2B15%5C%5Cy%3D%5Cfrac%7B-3%7D%7B5%7Dx%2B3)
As you can see, the slopes of the lines are equal, therefore, they are parallel.
If the lines are parallel then the system of equtions has no solution.
Answer:
=
Step-by-step explanation:
9, 6, 3, 0
a =Ist Term = 9.
Common difference is = T2 - T1 = 6 - 9 = -3.
The sequence is an Arithmetic Progression AP = a + (n-1)*d
Tn = a + (n-1)*d
Tn = 9 + (n-1)*(-3). Expand and simplify.
Tn = 9 - 3n +3.
Tn = 12 - 3n.
Hence the recursive formula is = 12 - 3n. Where n = position of term. n = 1, 2, 3, ..
