Answer:
The correct option is d.
Step-by-step explanation:
The given equations are
.... (1)
.... (2)
In equation 2, multiply both sides by 2.
.... (3)
Now add equation (1) and (3).
Divide both sides by 5.
Put this value in equation (2).
Therefore the solution of the system of equation is (2.4,0.2) and the system has only one solution. Option d is correct.
Answer:
y = -2x^2 -4x +1
Step-by-step explanation:
y-3 = -2 (x+1)^2
Foil (x+1)^2
(x+1)(x+1) = x^2 +x+x+1 = x^2 +2x+1
Substitute this back in
y-3 = -2(x^2 +2x+1)
Distribute
y-3 = -2x^2 -4x -2
Add 3 to each side
y-3+3 = -2x^2 -4x -2+3
y = -2x^2 -4x +1
Error= 0.1/2, 0.05
4.8 + 0.05 = 4.85
6.3 + 0.05 = 6.35
4.85 x 6.35 = 30.7975 cm (when rounded, gives 30.80 cm).
