(5x - 2)²
Step-by-step explanation:
25x² - 20 + 4
(5x - 2)(5x - 2)
(5x - 2)²
Answer: 2x^3
Step-by-step explanation: Find the prime factors of each term in order to find the GCF (Greatest Common Denominator).
Hope this helps you out! ☺
G(9,-3) being dilated by a scale factor of 1/3 is G'(3,-1) so D. All I did was divide the coordinates by 3 and there you go.
Have you tried multiplying 5(3)+2(2)+1?
15 + 4 + 1 = 20 ?
Im sorry I'm not real good with math.
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
