You plug in x+1.75 into the second equation to get 4x-2(x+1.75)=4. Once you simplify and solve that problem for x you should get x = 3.75. Plug the x-value that you got back into one of the equations (y=x+1.75) or (4x-2y=4). Either way your y-value should be 5.5.
Your answer would be A. because (x,y) or (3.75,5.5) in this case
A (x^4)/(9(y^3)) i would solve the equation with a caculator
Answer:
1.38
Step-by-step explanation:
tan Ø = 2/3
Ø = tan⁻¹(2/3)
Ø = 33.69
sin 33.69 ≈ 0.55
cos 33.69 ≈ 0.83
sin Ø + cos Ø ≈ 1.38
