Percy works two part-time jobs to 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 below3x + 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?

a. percy earns a greater hourly wage of $7.00 at the library.
b. percy earns a greater hourly wage of $7.00 at the coffee cart.
c. percy earns a greater hourly wage of $7.50 at the library.
d. percy earns a greater hourly wage of $7.50 at the coffee cart.

can you make your screen more see able?

then i might be able to .

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

the battle of gettysburg is considered the "high water mark" of the confederacy because it marked the greatest advance of the confederate forces against the union.

i believe it's a.

i'm not sure on this one, most likely correct.
