The answer is A I believe.
At hour 1, the equation must equal 130,
therefore s(1) = 9(1-1) + 130
s(1) = 9(0) + 130
s(1) = 130
then so on when
s(2) = 9(2-1) + 130
s(2) = 139
Answer:
An Integer is a whole number
Step-by-step explanation:
Integers can be positive, negative, and even zero.
Integers can't be fractions, decimals, ect.
An example of some Integers are:
1, 2, 3, 0, -1, -2 , -3
Hope this helps you out!
Divide everything by 4 getting:
7y=3x+21
then get all of the variables on one side by subtracting 3x:
7y-3x=21
2/9 is 32/144 in simplest form
Answer:
y = (x-0)^2 + (-5) ⇒ y = x^2 - 5
Step-by-step explanation:
The general vertex form of the parabola y = a(x - h)² + k
Where (h,k) is the coordinates of the vertex.
As shown at the graph the vertex of the parabola is the point (0, -5)
So,
y = a(x-0) + (-5)
y = ax^2 - 5
To find substitute with another point from the graph like (1,-4)
So, at x = 1 ⇒ y = -4
-4 = a * 1^2 - 5
a = -4 + 5 = 1
<u>So, the equation of the given parabola is ⇒ y = x^2 - 5</u>
