{-10, 9}
Step-by-step explanation:
The above are Simultaneous equations
<h2>
What are simultaneous equations?</h2>
These are two or more equations that share same variables.
8X + 10Y = 10--------(1)
5X + 4Y = -14-------(2)
<h3>Multiply equation (1) by 5 and equation (2) by 8</h3>
40X + 50Y = 50 ---------(3)
40X + 32Y = - 112--------(4)
<h3>Subtract equation (4) from (3)</h3>
18Y = 162
<h3>Divide bothsides by 18</h3>

<h3>Substitute y = 9 into equation (3)</h3>
40X + 50Y = 50
40X + 50(9) = 50
40X + 450 = 50
40X = 50 - 450
40X = - 400

Hello,
f(1)=2-9+12-12+10-3=0 ===>(x-1)*....
f(3)=2*3^5-9*3^4+12*3^3-12*3^2+10*3-3=0 ===> (x-3)*....
f(1/2)=2*(1/2)^5-9*(1/2)^4+12*(1/2)^3-12*(1/2)^2+10*1/2-3=0 ===>(2x-1)*...
f(x)=(x-1)(x-3)*(2x-1)*(x²+1)

The formula is
A=p (1+r/k)^kn
A future value?
P present value 500
R interest rate 0.05
N time 4 years
K compounded monthly 12
A=500×(1+0.05÷12)^(12×4)
A=610.45
