Answer:
(8, - 3 )
Step-by-step explanation:
Given the 2 equations
x - y = 11 → (1)
3x + 10y = - 6 → (2)
Multiplying (1) by 10 and adding to (2) will eliminate the y- term
10x - 10y = 110 → (3)
Add (2) and (3) term by term to eliminate y
13x + 0 = 104
13x = 104 ( divide both sides by 13 )
x = 8
Substitute x = 8 into either of the 2 equations and solve for y
Substituting into (2)
3(8) + 10y = - 6
24 + 10y = - 6 ( subtract 24 from both sides )
10y = - 30 ( divide both sides by 10 )
y = - 3
solution is (8, - 3 )
F(m)=4m(3m-2)
f(m)=12(m^2)-8m
f(-3.3)=12(-3.3^2)-8(-3.3)
f(-3.3)=12(10.89)-(-26.4)
f(-3.3)=130.68+26.4
f(-3.3)=157.08
Answer: The most typical system you will find is a system of linear equations. And frequently, you will find systems of equations that are linear, with two equations and two unknowns. These systems are usually call 2x2 system of linear equations.
