Which of these systems of linear equations has an infinite number of solutions? A. 5x - 2y = 10
12x - 4y = 20

B. 5x - 2y = 10
10x - 4y = 12

C. 5x - 2y = 10
10x - 4y = 20

D. 5x - 2y = 10
12x - 4y = 10

more detail

step-by-step explanation:

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45

good luck on ur quiz test or homework. have a good day : )
