So k in the first problem would =1/2
and i guess in the second problem just put k in place of the first space and in the second space put 8 for x. y would then =4. Idk if I did this right, though, I'm honestly a little confused too.
Answer:
D ( if you add +4 to the (x + 3)^2)
Step-by-step explanation:
Parent function is f(x) = x^2
A translation 3 units left gives y = )x + 3)^2
- and 4 up gives y = (x + 3)^2 + 4 - vertex form.
Standard form :
y = x^2 + 6x + 9 + 4
= x^2 + 6x + 13.
The perimeter of a shape is the sum of the lengths of its sides.
So, to find the perimeter of this quadrilateral, all we have to do is add the side lengths and simplify.
(x² - 6) + (2x + 5) + (x² - 3x) + (4x² + 2x)
x² + x² + 4x² + (-3x) + 2x + 2x + (-6) + 5
6x² + (-3x) + 2x + 2x + (-6) + 5
6x² + x + (-6) + 5
6x² + x + (-1)
6x² + x - 1
So, the perimeter of the quadrilateral is the quantity (6x² + x - 1).
Hope this helps!

if you divide the number and range them out. That's all i can tell you for now. Kinda busy. sorry
Answer:
Step-by-step explanation:
hello :
(x + 2)2 – 2(x + 2) – 15 = 0
let : t= x+2
t²-2t-15 =0
(t-5)(t+3)=0
t-5=0 or t+3=0
t=5 or t=-3
but : t =x+2
if : t=5 x+2 =5 so : x=3
if : t= -3 x+2 = -3 so : x= -5
conclusion two solutions : 3 , -5
