Answer:
Part A: the parabola opens upwards
Part B:
Part C: The vertex point is
Part D:
Part E: and
Step-by-step explanation:
We have the function:
Where the coefficients are:
a = 2
b = -6
c = 4
Part A:
Here we can see that the leading coefficient of our parabola (a = 2) is positive, so by the definition, the parabola opens upwards.
Part B:
The axis of the symmetry equation is given by:
Part C:
The vertex is the minimum point of our parabola.
Using the x value founded in Part B we can find f(x)=y.
Therefore, the vertex point is
Part D:
To get the y-intercept we just need to do x = 0.
The y-intercept is (0,4)
Part E:
To get the x-intercept we just need to do y = 0.
The x-intercept is (1,0) and (2,0)
I hope it helps you!
Answer:
40
Step-by-step explanation:
You can
1. Use a calculator if you are allowed and do 5 divided by eight and 3 divided by 10 and multiply the out comes = 0.1875
OR
2. set them up like fractions:
and multiply across
This question was kind of confusing but if you divide 121212 by 222 it results into 546 which then is multiplied by (I assume was ment) 1.51515 and you get 827.2719 minutes!
I searched it online and it seems similar to the following: instead of "222" laps it's "2" laps and its "1.5" instead of "1.51.51, point, 5", and "12" instead of "121212". In this case the answer would be 9 minutes!
Answer:
2) x=5
4) 6y-3
Step-by-step explanation:
2) 2x-3=7
Add 3 on both sides (-3+3 cancel each other out and 7+3 is 10)
Now your equation is 2x=10
Divide 2 from both sides
2x/2 cancel each other and 10/2 is. Therefore, x=5
4) 3(2y-1)
3 times 2y is 6y
3 times -1 is -3 (negative times positive is negative)
Equation: 6y-3
