Three students, Javier, Sam, and Corrine, participated in a fundraiser where people donated a certain amount of money per lap that the student ran. Each student also had some initial donations that were collected before the run. The equations that represent each student's total donation,
y, based on the number of laps ran, x, is shown below.
Match each equation with the correct rate of change for that student.
$7.75 for every one lap
$19.50 for every one lap
$15 for every one lap
$19.17 for every one lap
$23.25 for every one lap
$16.32 for every one lap
>
Corrine had a total
donation
of $228.50 after 14 laps.
y-228.5 = 7.75fx-14)
Sam had a total donation
of $186 after 8 laps.
y = 19.5x + 30
Javier had a total donation
of $230 after 12 laps.
y-230 = 15(x - 12)

The answer would be d i think but i’m for sure it is not a and c

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
