Answer:

For input value, x = -6, output value will be y = 1.2

Step-by-step explanation:

In this question graph of a quadratic 'f' function has been given.

Input values of a function are represented by the x-values and output values by the y-values on the graph.

Let's take a point (5, -1) on this graph.

For input value of 5, output value of the function is (-1).

Similarly, for an input value of x = -6, output value of the function will be y = 1.2

[ordered pair (-6, 1.2) given on the graph)

Answer:

  D

Step-by-step explanation:

The x-values are evenly-spaced, so any linear function table will have constant differences between the y-values. Here are the y-differences for the different options:

  A 1, 2, 4

  B 1, -1, 3

  C -1, -2, 1

  D 5, 5, 5 . . . . this represents a linear function

The ages of three siblings are consecutive integers. The sum of their ages is 42. Calculate their ages. *
stealth61 [152]

Answer:

13, 14, 15

Step-by-step explanation:

Let x = age of one of the siblings

Since the age of the siblings are consecutive integers, the age of the next sibling would be x + 1 and the age of the third sibling would be x + 2

x +( x +1) + (x +2) = 42

3x + 3 = 42

collect like terms and solve for x

x = 13

The age of the first sibling is 13

The age of the second sibling is x + 1 = 13 + 1 = 14

The age of the third sibling is x + 2 = 13 + 2 = 15

Please help me with this question
Y_Kistochka [10]

Answer:

2(a - 4) + 5(b + 1) = 8. The result of this equation when solving is a = - 5b/2 + 11/2.

3(a - 1) - 2(b - 2) = -11. The result of this equation when solving is a = 2b/3 - 4.

Step-by-step explanation:

Hope this helps =)
