Answer:
y = 1
Step-by-step explanation:
Given:
- equation of the parabola:
- points on the parabola: (-1, -9) and (1, 1)
Substitute point (1, 1) into the given equation of the parabola to find q:
Substitute the found value of q and point (-1, -9) into the given equation of the parabola to find a:
Therefore, the equation of the parabola is:
The maximum or minimum point on a parabola is the vertex.
Vertex form of a parabola: where (h, k) is the vertex.
Therefore, the vertex of the parabola is (1, 1) and so the maximum value of y = 1
The equation in slope-intercept form that represents the total fee "y"
to become a member of the library-all-star-members club for "x"
months is y = 2 x + 40
Step-by-step explanation:
The linear in the form of slope-intercept is y = m x + c, where
1. m is the slope of the line
2. c is the y-intercept
Slope of the line represents the monthly fee ⇒ paid every month
y-intercept represents the sign-up fee ⇒ paid once
To become a member of the library-all-star-members club, there is
a $40 sign-up fee and a $2 monthly fee
∵ The monthly fee is $2
∴ m = 2
∵ The sign-up fee is $40
∴ c = 40
∴ The equation is y = 2 x + 40, where y is the total member fee for
x months in the library-all-star-members club
The equation in slope-intercept form that represents the total fee "y"
to become a member of the library-all-star-members club for "x"
months is y = 2 x + 40

I think what the question asks is T.A = K
Answer:
7 years
Step-by-step explanation:
Simple interest is given by
I = PRT where I is the interest, P is the principle r is the rate and t is time
If we have 249 in the account and started with 200,
the interest is 249-200 = 49
The principle is 200 and the rate is 3.5% or in decimal form .035
Putting into the equation
49 = 200 (.035) t
49 =7t
Divide each side by 7
49/7 = 7t/7
7 =t
