Ok let’s solve it
5(x-2)^2-20=0
first let’s foil (x-2)
5(x^2-4x+4) -20=0
now distribute the 5
5x^2 -20x +20 -20 = 0
combine like terms
5x^2-20x=0
take the gcf
5x(x-4)=0
x=0, 4
solutions are (4,0) and (2, -20) because the original vertex form a(x-h)^2+k
Answer:
what is it?
Step-by-step explanation:
what's up? to convert this into a fraction, simply multiply 12.3/1 by 10 in order to get 123/10. you can also do it by seeing .3 is in tenths, so it would be 3/10. you are left with 12 (whole number) so 12 3/10 which is also 123/10
best of luck with your studies
Answer:
The equation of the line is:
Therefore, option a is the correct answer.
Step-by-step explanation:
Given the points
Finding the slope
As the point-slope form of the equation of the line is
where m is the slope
substituting the values and the point (-2, 2)
∵
Add 2 to both sides
Hence, the equation of the line is:
Therefore, option a is the correct answer.
(k-9)²
=(k-9)(k-9)
=k(k)-9(k)-9(k)-9(-9)
=k²-9k-9k+81
=k²-18k+81. As a result, the product of (k – 9)2 using the perfect square trinomial rule shown on the left is k²-18k+81. Hope it help!
