The square root of 28 is equivalent to 2 x the square root of 7
the square root of 252 is equivalent to 6 x the square root of 7
the square root of 36 is 6
Answer:
2.5 • 10^6
Explanation:
In order for 25 • 10^6 to be written in standard form, the ‘25’ needs to be less than 10. To do that we will move the decimal one place to the left so that 25 is now 2.5; it is now a number less than 10. It should now look like 2.5 • 10^6. It is now in standard form.
X=+-4
positive and negative 4
Answer:
The (x,y) point of the vertex is usually labelled as:
Vertex = (h, k)
h = -b / 2a
k = ah^2 + bh + c
f(x) = -3x^2 + 12x -5
a = -3 b=12 c=-5
h = -12 / -6 therefore h = 2
k = -3*2^2 + 12*2 -5
k = -12 + 24 -5 therefore k = 7
Vertex (2, 7)

Step-by-step explanation:
Answer:
No, (3, 9) is not a solution of the system.
Step-by-step explanation:
y=3x
2x-y=6
-----------
3(3)=9
2(3)-9=6-9=-3, not 6
