Answer:
7/3
Step-by-step explanation:
because (x,y) is the coordinates , 3/2 is y
y = 3/2
plug in y
x * 4 * 3/2 = 14
solve
x*6 =14
simplify
x= 14/6 = 7/3
The answer is b 5x-y=7 2x+y=0

Let's first define variables.
y: number of shares of $ 10
x: number of shares of $ 12
We write the system of equations:
10x + 12y = 210
y = 2x + 5
Solving the system:
x = 75/17
y = 235/17
Answer:
she has:
75/17 shares of $ 12
235/17 shares of $ 10
Assuming 5a3 equals 5a^3, and the same for everything else, you would plug in 4 for a, so 5(4)^3 - 2(4)^2 + 4 - 45, which equals 247.
