Haley S.

first, solve for x in the first equation, which gives you x=(9-4y)/3 then, plug into the x in the second equation: 5((9-4y)/3)-7y=3 solve for y: y=36/41 plug y=36/41 into first equation and solve for x: 3x+4(36/41)=9 --> x=75/41. yayyyy you solved a system of equations

Haley S.

the derivative of x^2 is 2x because the derivative of an expression in the form x^n is always nx^(n-1)

Question:

translate: amo canes

"i love dogs"... because amo is the 1st person, present form of the verb "amo, amare" meaning "to love" and canes is the plural, accusative case form of the noun "canis" meaning "dog"
