Answer:
Joint variation
Step-by-step explanation:
(a+b) (x+y-(y+z)) remove the parentheses
(a+b)(x+y-y-z) remove the opposites
(a+b)(x-z)
Answer:
C) y=3x-10
Step-by-step explanation:
All options given are in slope-intercept form.
m - slope
b - y-intercept
We are looking for the equation with a y-intercept of -10 and a slope of 3.
Options A and B have a y-intercept of -3 and 3. So, they are not the best answers.
Option D has a y-intercept of 10, not -10.
Option C has a slope of 3 and a y-intercept of -10.
This means that Option C will be the best answer.
Hope this helps.
Answer: 13
Step-by-step explanation:
8-10= 2 - 9 = 11 - 2 = 13 soo that how you got the answer 13 .
Answer:
Option C is correct.
288 degree measure could he have rotated the pentagon so that is mapped onto itself
Step-by-step explanation:
Given: Patrik rotated the pentagon about its center.
A Rotational symmetry of a regular polygon is based on the number of vertices it has.
If the Pentagon figure is rotated about its center, each vertex lands exactly on the top of where it started.
Since you have 5 vertices, so your starting vertex can land in 5 different starting places and still come up with the same figure.
So if you take rotations to each consecutive vertex.
⇒a rotation of 72 degree, 144 degree, 216 degree, 288 degree and 360 degree will result in the same figure.
Therefore, 288 degree measure could he have rotated the pentagon so that is mapped onto itself.
