to get the equation of any straight line, we simply need two points off of it, so hmmm let's use say (-1 , -1.25) and (8 , -3.5)


To find the total number of combinations, multiply all the choices together:
3 eggs x 4 meats x 5 breads x 6 juices x 4 beverages:
3 x 4 x 5 x 6 x 4 = 1,440 different breakfasts
An applicable equation of a vertical parabola in vertex form is:
y-k = a(x-h)^2
Let x=2, y=4, h=-1 and k=-1, where (h,k) is the vertex. Then,
4-(-1) = a(2-[-1])^2, which becomes 5 = a(9). Therefore, a = 5/9, and the
equation of the parabola is
y+1 = (5/9)(x+1)
<span>Which of the following equals 140 to nearest 10
A.134
B.145
C.136
D.146</span>
I assume the equation is supposed to be

Then we can write

Take the logarithm of base 3/8 on both sides:



- - -
If the equation is actually
, I'm afraid it cannot be solved exactly.
