digit at tens place of two digit number is twice the digit at units place .if sum of this number and the no.formed by reversing
Dima020 [189]
Let the number be     xy ,

xy = 10x + y.   when reversed = yx = 10y + x

x = 2y          ........(a)

10x + y + 10y + x = 66.........(b)

10(2y) + y + 10y + 2y = 66

20y + y + 10y + 2y = 66

33y = 66

y = 66/33

y = 2

x = 2y = 2*2 = 4

Recall the original number is xy =     42.

Please solve for me ill give brainliest
Black_prince [1.1K]

Answer:

\displaystyle (0, -1); maximum

Step-by-step explanation:

First off, <em>B</em> is zero, so there is no <em>phase shift</em>, meaning that the vertex stays on the y-axis. Next, <em>A</em> is negative, so the parabola opens down, and whenever you have a parabola opening down, it does so at maximum. Finally, <em>C</em> represents our y-intercept, or in this case, our <em>vertical shift</em>. Our y-intercept is (0, −1), and so as our vertex, hence our answer.

I am joyous to assist you anytime.
