Answers
Direct Variation; k=3 best describes the function on the graph
Option A)
Direct variation is a linear function defined by an equation of the form y = kx when x is not equal to zero. Inverse variation is a nonlinear function defined by an equation of the form xy = k when x is not equal to zero and k is a nonzero real number constant. In direct variation, as one number increases, so does the other. This is also called direct proportion: they're the same thing. An example of this is relationship between age and height. As the age in years of a child increases, the height will also increase. In inverse variation, it's exactly the opposite: as one number increases, the other decreases. This is also called inverse proportion. An example would be the relationship between time spent goofing off in class and your grade on the midterm. The more you goof off, the lower your score on the test
The given equation is a Straight line with equation y = 3x.
Thus the given graph is direct Variation graph with k=3.

Convert the following quadratic equation to vertex form. 2) 3x2 - 12x - 5
Answers
Answer:
2*12x-5
Step-by-step explanation:
In geometry, a vertex form is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices. For example, a square has four corners, each is called a vertex.

Answers
Answer:
14x + 6y = 10
14x + 35y = -77
Step-by-step explanation:
Multiply the top one by 2
14x + 6y = 10
Multiply the bottom one by 7
14x + 35y = -77
His next step is to subtract. You could have done this by multiplying the top one by -2
-14x - 6y = - 10
14x + 35y = -77 Now all you need do is add. The question now becomes what do you do? What answer do you give? I think the expected answer is the top two equations, but if I was actually doing the problem, I'd use the bottom 2.
Answer:
A) 14x + 6y = 10
-14x - 35y = 77
Step-by-step explanation:
multiple the first equation by 2 and the second equation by -7
2( 7x + 3y = 5)
-7( 2x + 5y = -11)
14x + 6y = 10
-14x - 35y = 77

By what percent will a fraction change if its numerator decreases by 85% and the denominator decreased by 25%
Answers
Let x/y be the original fraction.
After decreasing the numerator by 50% and decreasing the denominator by 25%, the fraction is:
(x - 0.5x) / (y - 0.25y) = (0.5x) / (0.75y)
= (2/3)(x/y) = 66 2/3% of x/y
So, the fraction decreased by 33 1/3%.
The correct answer is 80%

The elevator of John Hancock Center in Chicago travels at a faster rate.
The standard equation of a line is y = m + bm is the slope or rate of changeb is the y-intercept.For the equation represented by the height of the elevator of John Hancock Center in Chicago given as y = 30x, the rate of change is 30 ft/s which is equivalent to 1800 per minute.
Since the express elevator in the Empire State Building in New York City travels nonstop from the ground floor to the top floor at a rate of 1,400 feet per minute, hence the elevator of John Hancock Center in Chicago travels at a faster rate.
