Answer:
x = -X OR x = 0
Step-by-step explanation:
I don't know if the capital 'X' was a different variable, so I did both calculations.
2(x - 3) + 9 = 3(x + 1) + X
= 2x - 6 + 9 = 3x + 3 + X
= 2x + 3 = X + 3x + 3
= -x = X
= x = -X
2(x - 3) + 9 = 3(x + 1) + x
= 2x - 6 + 9 = 3x + 3 + x
= 2x + 3 = 4x + 3
= -2x = 0
= x = 0
Answer:
C, 2.15
Step-by-step explanation:
Arabian Plate: 1.29x10^-4 = .000129
African Plate: 6x10^-5 = .000006
Once you've converted both into standard form, divide them to find the difference.
.000129/.000006 = 2.15
Maybe it is $9.00
2 x 9 = 18
$2 per inch
18 divided by 2
$9.00?
All you do is multiply 2 by 10 to the power of -6. 2*10^(-6)
Answer:

Step-by-step explanation:
The equation of a quadratic function in vertex form is given by:

Where (h,k) is the vertex.
It was given in the question that the vertex of the parabola is (-1,4).
When we substitute the vertex into the formula we get:

The parabola also passes through (4,19) hence it must satisfy its equation.



We divide both sides by 25 to get:

Hence the quadratic function is:
