Answer:
y=2x^2 + 2x - 3 x -2 -1 0 1 2
Step By Step Explanation:
The values can be find by plugging the x values in the equation which gives us the y value ,
x -2 -1 0 1 2
y 1 -3 -3 1 9
(b) Plot the points on the graph and join by a smooth curve.
(c) The line y=1 will be passing through 1 and parallel to x-axis.
(d) solve 2x^2 + 2x - 3 = 1
Subtract 1 from both the sides ,
2x^2 + 2x - 2 = 0
Factoring out the 2 from the equation ,
2(x^2 + x - 1) = 0
x^2 + x - 1 = 0
Apply the quadratic formula
x=(-1-sqrt(5))/2 and x = (-1+sqrt(5))/5
Answer:
Step-by-step explanation:
a= adult ticket
a= student ticket
5a+1s=2874
1a+1s=1246
Subtract the second equation from the first one
4a=1628
a=407
a+s=1246
407+s=1246
s=839
We have
C is the cost
x is the units of a product at the factory
If
C= 35170
we need to find the value of x
The equation given is
so we have the value of C, so the equation if we substitute the value of C is
we need to isolate the x
In that month,490 units can be produced for $35170.
