Answer:
a) (1,3)
b) x=1
Step-by-step explanation:
The general form of a parabola in vertex form is f(x)=a(x-h)^2+k, where h is the x coordinate of the vertex, and k is the y coordinate, while a indicates how "squished" the graph is, or how quickly it grows in relation to the parent graph. In this case, h is shown to be 1, and k is 3, meaning that the vertex is at (1,3). The axis of symmetry , for a vertical parabola, just runs vertically through the vertex, meaning that in this case it is at x=1. Hope this helps!
Answer: B. Linear
Step-by-step explanation: Y: -5, -1, 1, 3, 7
X: -3, -1, 0, 1, 3
Ok, when you are doing a problem like this you are going to have to line you X and Y's up from least to greatest. Then, you will look at the X and see if any of the X values repeat. If any of your X values repeat, then they are "Non-Linear." If they do not repeat, then that means they are "Linear."
25÷100=0.25
0.25×680=170 is the answer
Answer:
The coordinates are: (-3,-4).
First, I would simplify the given equation to find the slope of the parallel line as it will be the same for the line we are looking for.
3y=x+12
y=(x/3)+4
Slope= 1/3
Our equation now looks close, but we need the intercept.
y=(x/3)+B
Plug in the given point to find the intercept.
3=(-1/3)+B
4/3=B
Plug all the known values into the equation to complete the slope-intercept form.
y=(x/3)+4/3
