How to solve to system y=x^2-2 y=2x+1
vovikov84 [41]

Answer:

the solutions are (3, 7) and (-1, -1)

Step-by-step explanation:

Insert the " = " symbol between the two equations, obtaining:

y = x^2 - 2 = y = 2x + 1

Then x^2 - 2 = 2x + 1, or

x^2 - 2x - 3 = 0, and this can be factored into (x - 3)(x + 1) = 0.

Thus, the x values that satisfy this system are {-1, 3}.

Use y = 2x + 1 to find the corresponding y values:

y = 2(-1) + 1 = -1

and

y = 2(3) + 1 = 7

Then the solutions are (3, 7) and (-1, -1)

Use the table to determine the appropriate model of the function, x       0             1             2             3

Points Lying on the undefined curve are

x :   0     1      2     3      4

f(x): 3    7     29    87    199

Plotting the points on the coordinate plane

As you will see, the value of x increases , value of y increases .

It is not linear, because slope between two points is not same.

Neither quadratic nor cubic  , it is not cutting x axis .

So, As value of x increases, value of y does not increases by a fixed quantity, but it increases.

So, option (D) Exponential ,Function word is the right word Describing these points.

Question is in picture ​
Vedmedyk [2.9K]

Answer:

C. 60%

Step-by-step explanation:

<u>Consider 1st row of table</u>

Total Price = P= 22.50

Discount=D=13.50

Percent discount=(D/P) x 100

                           =(13.5/22.5) x 100

                          = 60%

<u>Consider 2nd row of table</u>

Total Price = P= 27

Discount=D=16.20

Percent discount=(D/P) x 100

                           =(16.2/27) x 100

                          = 60%

Now we know discount rate is r=60%
