Answer:
-5
Step-by-step explanation:
H is the value that is being added or subtracted from x in the equation
f(x)=a(x-h)^2 +k
The geometry sequence has the equation 
.
The 5 represents the first number of the sequence and the 3 represents the common ratio.
a(5) = 
answer: 405
The function is computed below based on the information. The answers will be:
1. -11
2. -1
<h3>How to compute the function?</h3>
f(x) = x²-11x+28
g(x) = x-4
(f+g)(-5) = (-5² - 11 × 5 + 28) + (-5 - 4)
= 25 - 55 + 28 - 9
= -11
(f-g)(5)
= = (5² - 11 × 5 + 28) + (5 - 4)
= 25 - 55 + 28 + 1
= -1

#SPJ1
She originally started with 23.
We can tell this by working the equation backwards. Since she has 5 left and she had just given half to her brother, we know she had 10 a moment ago.
Before that, Mary had eaten a cookie. So we add 1 to the total and now have 11.
Before eating that cookie, she has given half to her sister, which would give her 22.
And before giving half to her sister, she had eaten the first one, which would give us 23 to start with.
Answer:
D. (y+1)=5(x+2)
Step-by-step explanation:
Point-slope form follows: y - y1 = m(x - x1)
Since both x and y are negative for (-2,-1), it becomes a positive because two -'s become a +.
m(slope)=5
y-(-1)=5(x-(-2))
y+5=5(x+2)
