<span>get their dot product, if the dot product is 0, then they're orthogonal (perpendicular).

also keep in mind that, if two vectors bear the same slope, namely <a,b> and <c,d>  and the simplified slope b/a  is the same value as d/c, then they're parallel vectors.</span>

It would be y=8x+2/3

Explanation:
Y=|3/4x| is an absolute value
Y=x^3+8 is quadratic
Y=8+5/6x^2 is also quadratic (you can tell it’s quadratic because it has an exponent)

Find the equation of a line passing through the point (2, 3) and having a slope of 3.
Delvig [45]

Answer:

The answer to your question is the letter B) y = 3x - 3

Step-by-step explanation:

Data

Point = (2, 3)

slope = m = 3

Process

To solve this problem just substitute the values given in the slope-point equation.

Formula

               y - y1 = m(x - x1)

   x1 = 2      y1 = 3

-Substitution

              y - 3 = 3(x - 2)

-Expand

              y - 3 = 3x - 6

-Solve for y

             y = 3x - 6 + 3

-Result

             y = 3x - 3

The united states government produced about 10.25 billion pennies one year.
Elenna [48]
1) 10.25 x 10^9 in scientific notation is 1.025 x 10^10

2) Now you have to subtract 10.25x10^9 - 3.0x10^7

To make that you have to put both numbers with the same power of ten.

1025x10^7 - 3.0x10^7 = 1022x10^7 more pennies than half-dollars.

Find the area. simplify your answer.
PolarNik [594]

Answer:

The area is:

2 {x}^{2}

Step-by-step explanation:

Area of this figure is simply the product of the base and the height, as it just happens to be a slanted or inclined rectangle.

Therefore:

a = 2x (x) = 2 {x}^{2}
