Answer: an equation that has one term which is nameless and squared also no term which gets raised to higher power.
Step-by-step explanation:
Answer:
Line 1, y=-3, x=-3
Line 2, y=2, x=1 1/3
Step-by-step explanation:
solution is (4, - 7 )
given the equations
y = 2x - 15 → (1)
4x + 3y = - 5 → (2)
substitute y = 2x - 15 into (2)
4x + 3(2x - 15) = - 5
4x + 6x - 45 = - 5
10x - 45 = - 5 ( add 45 to both sides )
10x = 40 ( divide both sides by 10 )
x = 4
substitute x = 4 into (1) for corresponding value of y
y = (2 × 4 ) - 15 = 8 - 15 = - 7
solution is (4, - 7 )
25 anything raised to zero equals one
