Answer:
Y = -2X + 7
Step-by-step explanation:
Y = a(x-h)^2 + k
From (h,k) h = 0 k = 7 x = 2 y = 3
3 = a(2-0) + 7
3 = 2a - 0 + 7
Collect like terms
2a = 3 - 7
2a = -4
Divide both sides by 2
2a/2 = -4/2
a = -2
y = a(x-h) + k
y = -2(x-0) + 7
y = -2x + 0 + 7
y = -2x + 7 or
y + 2x - 7 = 0
Answer:
D
Step-by-step explanation:
When somethin is decreasing you would subtract the percent it was decreasing by, by 1.
.024 - 1 = .976
Answer:
p+2=-15 step1:-2 on both sides

p=-17
The correct answer for the question that is being presented above is this one: "<span>C. 600 mi./hr. "</span>
Plane flies from City A to City B in 12 minutes. The distance is 120 miles.
12 minutes is just 0.2 of 60 minutes.
= 120 miles / 0.2 hour
= 600 miles / hour
Answer: 27
Step-by-step explanation:
The given sequence : 13, 24, 35, ....
Here, first term : a= 13
Common difference: d=24-13 =11
The nth term of arithmetic sequence is given by :-
It is given that the nth term is 299, so put 
Subtract 13 from both sides , we get
Divide both sides by 11, we get
Add 1 on both sides , we get
Hence, the value of n= 27
