<u>Answer:</u>
Beto will get to the school first.
<u>Step-by-step explanation:</u>
We are given that Delia lives 3/4 mile from school and walks at a pace of
16 minutes per mile.
So Delia takes 
12 minutes to reach school.
While Beto lives 3 1/2 miles from school and bikes at a pace of 3 minutes per mile.
So Beto takes 
10.5 minutes to reach school.
Therefore, Beto will get to the school first.
The inverse of the given function is y = √5x + 7/2 - 3
<h3>Inverse of a function</h3>
Given the function expressed below;
5y + 4 = (x+3)² +1/2
5y = (x+3)² - 7/2
y = 1/5(x+3)² - 7/10
Replace y as x
x = 1/5(y+3)² - 7/10
Make y the subject of the formula
5x = (y+3)²- 7/2
(y+3)² = 5x + 7/2
y+3 = √5x + 7/2
y = √5x + 7/2 - 3
Hence the inverse of the given function is y = √5x + 7/2 - 3

Answer:
7. Quadrilateral
8. Trapezoid
9. Quadrilateral
Pls mark me as Brainiest if that helped you :)
Step-by-step explanation:
F(x) = 2x² - 8x - 10.
This is a parabola open upward (since a>0) with an axis of symmetry = -b/2a:
a) axis of symmetry: x = -(-8)/(2*2) = 8/4 = 2. Then x = 2, which is the x component of the vertex
b) for x = 2, f(x) = f(2) = - 18 (component of y of the vertex)
c) VERTEX(2, - 18)
d) DISCRIMINENT: b² - 4.a.c = 64 - 4*2*(-10) = 144
