63x+ 82y-15x - 36y
= 48x + 46y
answer
C. 48x + 46y
Answer:
-6 and 3
Step-by-step explanation:
3-(-6)=3 +6=9 (two negative signs= positive sign)
-6 +3 = -3
It you have 6 negative tiles and add 3 positive tiles, the 3 negative tiles cancel 3 positive tiles. So hat is left is 3 negative tiles
An equation for the parabola would be y²=-19x.
Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form
(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.
Beginning with the directrix:
x=h-p=4.75
h-p=4.75
Since the vertex is at (0, 0), this means h=0 and k=0:
0-p=4.75
-p=4.75
p=-4.75
Substituting this into the standard form as well as our values for h and k we have:
(y-0)²=4(-4.75)(x-0)
y²=-19x
Answer:
False
Step-by-step explanation:
You are 1 unit more than the whole.
