7 (x+1)

Then there is an x in both x2 and 2x so you take that out.

x (x+2)

f 6 6 7 8 8

c = the number of children
f = the fee per hour

The given information is
f = $6 when c = 2;
f = $7 when c = 3;
f = $8 when c = 4 or c = 5.

A graph of the data is shown below.
Notice that the fee for 1 child was not provided, but it was provided in the table.

Let us examine the given answers.
(a) The relationship is not linear between c and f.
TRUE
(b) The relationship is linear between c and f.
FALSE
(c) The relationship is not linear for and linear for f.
FALSE
(d) The relationship is linear for c but not f.

Triangle ABC is transformed to create triangle MNO and triangle PQR as described below.

Alik [6]

The missing options are located here; brainly.com/question/18156103

The option that correctly describes the transformation that took place with triangle ABC is; Option A.

In transformations, translation simply means shifting an object from one position to the other while dilation simply means increasing or decreasing an object by a scale factor.

This means that translation preserves the lengths and angles of the object while the lengths and angles change with dilation.

Option A; Triangle MNO represents a translated triangle and as such the lengths and angles remain unchanged and so this option is correct.

Option B; Not true because both lengths and sides are preserved as stated above.

Option C; Transformation to PQR denotes dilation by a factor of 2 and as such the lengths and angles change. Thus this option is not true.

Option D; This is not true for the same reason in option C above.
