1 answer:
vichka [17]2 years ago

Answer:

  a, b – linear

  c – nonlinear

Step-by-step explanation:

When classifying a function from its table, you generally are looking at the way y changes when x changes. When the x-values are evenly-spaced, as they are here, then it is much easier to identify the function type from the y-values.

For evenly-spaced x-values ...

  y-values have a common difference: linear function

  y-values have changing differences: non-linear

     y-values have a common ratio: exponential function

     y-values have common "second differences": quadratic

__

a) Differences of y-values are ...

  11 -14 = -3, 8 -11 = -3, 5 -8 = -3 . . . linear function

b) Differences of y-values are ...

  -1 -(-3) = 2, 1 -(-1) = 2, 3 -1 = 2 . . . linear function

c) Differences of y-values are ...

  3 -5 = -2, 1 -3 = -2, 3 -1 = 2 . . . nonlinear function

Steven sold two less boxes of candy for the school fundraiser than Rodney with some of the boxes they sold with 8 how many boxes
wel
If Steven sold two boxes of candy less than Rodney and they sold 8 boxes, you can calculate how many boxes did each sell using the following steps:

Steven ... s = r - 2
Rodney ... r

s + r = 8
r - 2 + r = 8
2 * r = 8 + 2
2 * r = 10    /2
r = 5

s = r - 2 = 5 - 2 = 3

Result: Steven sold 3 boxes of candy and Rodney sold 5 boxes of candy.

The isosceles triangle below has one angle measure as shown what is the measure of each of the other angles?
SSSSS [86.1K]
The answer would be 65°.
This is because 180° -50° equals 130°. And 130° divided by two equals 65°. The two remaining angles must be equal because it is an isosceles triangle.
