Answer:
Vertex: (-1,-4)
Axis of Symmetry: x=-1
Step-by-step explanation:
The vertex is the minimum of the parabola, or (h,k), which is located at (-1,-4)
The axis of symmetry is a vertical line that marks the halfway point of the parabola, which is equal to x=h. Therefore, the axis of symmetry is x=-1
Answer:
y= 2x
Step-by-step explanation:
To figure out what the equation would be you would set up an equation..
16 = 8z
Then you find z
16/8 = 8z/8
2 = z
Now you can set up a variable expression although it isn't necessary
y = zx
Now you plug in the value of z to complete the equation
y= 2x
I hope this is what you wanted!!!
Answer:
there are 18 girls
Step-by-step explanation:
for every 2 boys there are 3 girls
so then you can say 2/5 of the class are boys and 3/5 are girls
and you have to calculate 3/5 of 30 so you have to divide 5 and then multiply by 3 so 30 divided by 5 is 6 the n multiply 6 by 3 and the answer is 18.
Hope this helps
Answer:
and
Step-by-step explanation:
A simple way to solve this problem is to plug the corresponding x and y into the function. We need only one pair since all the functions are quasi-linear (y=kx) and the increase is proportional.
In when x=3, y=15/4≈2.14
In when x=3, y=1.8
In when x=3, y≈2.33
In when x=3, y≈1.90
We can observe that in two cases, and , y is greater than 2.
