Answer: Hello mate!
We have the equation 2x^2 + x = 14
let's solve it for x:
2x^2 + x - 14 = 0
the solutions can be obtained with the equation:
then the solutions are:
(-1 - 10.63)/4 = -2.907, that rounded to the hundreths is equal to -2.91 (because the number after the hundredth place is a 7, so we round up)
and
(-1 +10.63)/4 = 2.407, that when rounded to the hundreths place is equal to 2.41 (the same reason as before)
then the answers are -2.91 and 2.41
Answer:
the one on the right
Step-by-step explanation:
one input cannot have more than one output
Answer:
7x-4y=-8.........(i)
y=3/4x-3........(ii)
Putting the value of y in eqn(i)
7x-4y=-8
or, 7x-4(3/4x-3)=-8
or, 7x-3x+12=-8
or, 4x=-8-12
or, x=-20/4
x=-5
again,
putting the value of x in eqn(ii)
y=3/4x-3
y=-5(3/4) -3
y=-15/4 -3
y=-3/4
x=-5
y=-3/4
