The expression 7•3x is not equal to the expression 21x. You might think that the two expressions are the same since 7x3 is 21 but the first expression is a dot product. This kind of expression includes the magnitude and direction of the vector in an expression, for example, <span>7•3x. The second expression, 21x, expresses only the magnitude and does not include the direction.</span>
Okay so basically an integer is just a whole number that isn’t a fraction. Comparing integers is basically comparing whole numbers. For example, comparing the numbers 2 and 34 would be 2<34 and that’s comparing them to each other! :)
Answer:
See below.
Step-by-step explanation:
<u>Simplify</u>
y - 2 = 5(x - 6)
y - 2 = 5x - 30
y = 5x - 28

Answer:

Step-by-step explanation:
The equation of a hyperbola centered at the origin with vertices on the y-axis is given by: 
The vertices of the hyperbola are the y-intercepts (0,12) and (0,-12)
This implies that:



The asymptote equation of a hyperbola is given by:

The given hyperbola has asymptote: 
By comparison; 


The required equation is:
