So, it looks like all your answers for the axis of symmetry are correct. I'm guessing you only need help on the value of the vertex.

The vertex is the peak of curve of the parabola.

In the first graph y= 3.
In the second graph, y= -3
In the third graph, y=3
In the fourth graph, y= -3

However, I can not see the lines of the graph very well, and these numbers are just what I believe the values to be. Now that you know what the vertex is and the estimated values of y, can you figure out the rest of the problem?

La suma de dos número impares consecutivos es 100 . hallar la suma de cifras del mayor<br> numero

gtnhenbr [62]

<h2><u>solución</u></h2>

deja que los números sean x, and x + 2

sabemos que su suma es igual a 100, entonces

x + x + 2 = 100

2x = 100 - 2

2x = 98

x = 98 ÷ 2

x = 49

por lo tanto, el primer número es 49

y el segundo número es x + 2 = 49 + 2 = 51 (también es el mayor entre los dos números)

entonces suma de dígitos de mayor número = 5 + 1 = 6

Respuesta correcta de la pregunta anterior = 6

You have used the Distributive Property to transform numerical expressions such as (5)(3) + (2)(3) to (5 + 2)(3). How would you

5x + 2x.....combine like terms..... = 7x

5x + 2x....subbing in 1 7x - 1....subbing in 1
5(1) + 2(1) = 5 + 2 = 7 7(1) - 1 = 7 - 1 = 6

5x + 2x...subbing in 2 7x - 1...subbing in 2
5(2) + 2(2) = 10 + 4 = 14 7(2) - 1 = 14 - 1 = 13

5x + 2x...subbing in 3 7x - 1...subbing in 3
5(3) + 2(3) = 15 + 6 = 21 7(3) - 1 = 21 - 1 = 20

5x + 2x...subbing in 4 7x - 1....subbing in 4
5(4) + 2(4) = 20 + 8 = 28 7(4) - 1 = 28 - 1 = 27

5x + 2x...subbing in 5 7x - 1...subbing in 5
5(5) + 2(5) = 25 + 10 = 35 7(5) - 1 = 35 - 1 = 34

5x + 2x result values are 1 more then 7x - 1 result values
there are no values that will make the 2 expressions equal....
because 5x + 2x = 7x......and the other one is 7x - 1......so the 7x - 1 values will always be 1 number less...because ur subtracting one
