An equation that goes through (-2, 1) and has a slope of 4 is y = 4x + 9.


You can find this by looking for the y-intercept (b) by using the slope (m), the point and slope intercept form. The work is below for you.


y = mx + b

1 = 4(-2) + b

1 = -8 + b

9 = b


Now we can use that and the slope to create the equation y = 4x + 9

nataly862011 [7]

Answer:

Company C!

Step-by-step explanation:

In order to see which company has the best buy  we have to see the amount each company sells for one stuffed mascot. In order to do this we have to divide .

Company A:

Company A sells 16 lions for $44.32 this is the same as 1 stuffed lion for $2.77.

Company B:

Company B sells 18 lions for $50.22 this is the same as 1 stuffed lion for  $2.79.

Company C:

Company C sells 12 lions for $32.88 this is the same as 1 stuffed lion for $2.74

Thus as you can see the company with the best buy is company C.

Which of the following statements are true about the graph of f(x) = 6(x + 1)2 -9?
Sphinxa [80]

Answer:

Step-by-step explanation:

a. The vertex is (1, -9).  False.  The vertex is (-1, -9).

b. The graph opens upward.  True.  That coefficient '6' is positive.

c. The graph is obtained by shifting the graph of f(x) = 6(x + 1)2 up 9 units.  False.  It's DOWN 9 units.

d. The graph is steeper than the graph of f(x) = x^2.  True.  The given function increases 6 times faster than does x^2.

e. The graph is the same as the graph of f(x) = 6x2 + 12x - 3.

Let's put f(x) = 6(x + 1)^2 -9 into standard form.  Expanding the first term, we get f(x) = 6(x^2 + 2x + 1) - 9, or f(x) = 6x^2 + 12x + 6 - 9.  YES, TRUE
