Yes because it passes the vertical line test (meaning that every x-value has exactly one y-value)

Answer:

yes

Step-by-step explanation:

it passes the verticle line test which states that if you put a verticle line anywhere on the graph it will only have one point in where the two lines intersect

Write each vector in component form

meriva

Answer to problem 1 is (9,9)
Answer to problem 2 is (0,-4)

----------------------------------------------------

Explanation:

To find the component form, they basically want the translation rule. To find the translation rule, we subtract the coordinates tip - head

In general, if we have two vectors M and N such that
M = (a,b)
N = (c,d)
then
vector MN = (c-a, d-b)

Applying this to the vector CD gives us
vector CD = (7-(-2), 10-1) = (7+2, 10-1) = (9, 9)
Basically meaning that we shift point C nine units to the right and nine units up to get to point D

Similarly,
vector RS = (-4-(-4), -3-1) = (-4+4, -3-1) = (0,-4)
so we shift point R four units down to get to point S

The perimeter of a rectangle is 100 inches. If the length of the rectangle is (3x + 5) inches, and the width is (x – 9) inches.

hodyreva [135]

Answer:

value of x is 13.5 inches.

hope this answer helps you dear....take care!

perimeter = 2l + 2b too and it is also 

2 ( l + b )

→ 2l + 2b

breadth and width are same!
