Given:
The graph of a parabola.
To find:
The equation of the parabola.
Solution:
From the given graph, it is clear that the vertex of the parabola is at point (0,0) and it is a horizontal parabola.
The general equation of a horizontal parabola is:
Where, a is a constant.
If a<0, then the parabola opens left and if a>0, then the parabola opens right.
Equations in options B and D are of the form but a<0 in option B and a>0 in option D.
In the given graph the parabola opens right, so the value of a mus be a positive number. So, the required equation is:
Therefore, the correct option is D.
7x-10 is greater than or equal to 16.
First, add 10 to both sides.
This will give you 7x is greater than or equal to 26.
Now, you dived 26 by 7.
This gives you 3.7142. Hope this helped!
Answer:
10
Step-by-step explanation:
E={2,3,5,7, 11, 13, 17, 19, 23, 29}
therefore,
n(E)={10}
Hello,
x²+5x-6=0
Δ=5²+4*6=49=7²
x=(-5+7)/2 or x=(-5-7)2
==>x=1 or x=-6
Answer B
M = (22 - 7)/(8 - 5) = 15/3 = 5
<span>using point (5, 7) </span>
<span>y - 7 = 5(x - 5) in point-slope form </span>
<span>y - 7 = 5x - 25 </span>
<span>y = 5x - 18 in slope-intercept form.</span>
