Percy works two part-time jobs to help pay for college classes. On Monday, he works 3 hours at the library and 2 hours at the coffee cart and earns $36.50. On Tuesday, he works 2 hours at the library and 5 hours at the coffee cart and earns $50. His hourly wage at the library, x, and hourly wage at the coffee cart, y, can be determined using the system of equations below.3x + 2y = 36.50

2x + 5y = 50.00

At which job does Percy earn the greater hourly wage? How much does Percy earn each hour at this job?

Answers

The answer is C. Percy earns a greater hourly wage of $7.50 at the library.

Axis of symmetry and vertex of F (x) = x2 + 4x -5

Answers

axis of symmetry is also the x coordinate of the vertex
if you have
f(x)=ax^2+bx+c
vertex x coordinate is
-b/2a
a=1
b=4
-4/2(1)=-4/2=-2
x coordinate of vertex=-2 aka axis of symmmetry
find y coordinate
input -2 for x
y=(-2)^2+4(-2)-5
y=4-8-5
y=-9

axis of symmetry is x=-2
vertex is (-2,-9)

r= -b/2a = -4/2=-2 k=f(r)=-2^2-8-5=-9 (-2,-9)
