Answer:
Third option
Step-by-step explanation:
In this case we must write a quadratic equation in the vertex form.
We have the vertice. (-1, 5)
We know that the vertex form for a quadratic equation is:
.
Where (h, k) is the vertex.
So if the vertex is (-1, 5), the equation sought is:
Therefore the answer is the Third option.
Answer:
x = 77 degrees
Step-by-step explanation:
To get the value of x, we use the angle arc relationship
Mathematically, we have this as follows;
x = (76 + 78)/2
x = 77
Answer:
4250 times a minute
Step-by-step explanation:
5 x 850 =
Step-by-step explanation:
I think you are trying to find x, I dunno, but if you are here's the solution.
when trying to find x, your main goal is to shift all x terms to one side.
For the first one
4x-3 = 5x-3
Carry all x terms to one side:
(4x-3)-5x = (5x-3)-5x
4x-5x-3 = -3
Shift all constants (purely just numbers, no x) to the other side
(4x-5x-3)+3 = (-3)+3
4x-5x = 0
-x = 0
x = 0
The second one:
-2x = 3x-5
5x = -5
x = -1
Done, have fun with math!
Answer:
Step-by-step explanation:
72 + 4t > 400
X could = 83 (since 82 will give you 400) or higher
