(04.07A MC) The figure below shows a line graph and two shaded triangles that are similar:
o
- 15-12-253036 9 12 15
Which statement about the slope of the line is true? (5 points)
Ont is throughout the line
O
It is -3 throughout the line.
The slope from point o to point is times the slope of the line from point A to point B.
O
The slope from point o to point A is 3 times the slope of the line from point A to point B.

What is the perimeter, p, of a rectangle that has a length of x + 8 and a width of y − 1? p = 2x + 2y + 18 p = 2x + 2y + 14 p = x + y − 9 p = x + y + 7

An equation where variables are used to represent known values—function notation true or false

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
