For the equation --4y = 8x, what is the constant of variation?
larisa86 [58]

Answer: 1) B is correct, constant of variation is -2.

Step-by-step explanation:

1)

Direct variation states that a relationship between the two variables. we say y varies directly as x

i.e,  or y =kx.................[1] ;  where k is the constant of variation.

Given the equation:

Divide both sides by -4 we get;

Simplify:

            .......[2]

On comparing equation [2] with [1] we get;

k = -2

What transformations were applied to the graph of the parent function y=tan(x) to produce the function graphed below?
xxMikexx [17]

Answer:

It's D.

Step-by-step explanation:

The graph of tan x passes through (0,0)  whereas this graph passes through the point (pi/4 , 0) so it  a horizontal  translation to the right.  We see that the  period is 6 units along the x axis which is  6 * pi/4 = 3 pi/2.

The degree of the function f(x) = -(x + 1)2(2x - 3)(x + 2)2 is<br> , and its y-intercept is
Serggg [28]

Answer:

Degree = 5

Y intercept = 12

Step-by-step explanation:

our function is given as

f(x)=-(x+1)^2 \cdot (2x-3) \cdot (x+2)^2

in the above polynomial our variable is x and it is being multiplied for 5 times. Hence the probable degree for the above polynomial is 5

In order to find the y intercept , we need to put x=0 in f(x) as y intercept is the point at which the function graphically meets y axis and where x = 0

Hence

f(0)=-(0+1)^2 \cdot (2(0)-3) \cdot (0+2)^2

f(0)=-(1)^2 \cdot (0-3) \cdot (2)^2

f(0)=-1 \cdot (-3) \cdot 4

f(0)=3 \cdot 4

f(0)=3 \times 4

f(0)=12

Hence the y intercept is 12 units
