A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
DedPeter [7]

Answer:

C

Step-by-step explanation:

Any time you move up or down, it affects the "y" coordinate, and going up is positive so 5 units up is y + 5.

Moving left or right affects the "x" coordinate and moving left is negative so

x - 3

(x - 3, y + 5)

 Hence, C is the correct answer

PLEASE HELP WILL GIVE BRAINLIEST TO CORRECT ANSWER
ioda

Answer:

Step-by-step explanation:

h(x) = 7 - x - 2x^5

h(-1) = 7 + 1 - 2(-1)^5

h(-1) = 7 + 1 + 2

h(-1) = 10

Now differentiate h(x)

h'(x) = -1 - 2*5*x^4

h'(x) = -1 - 10x^4

h'(x) = -1 - 10(x)^4

h'(x) = -1 - 10 (x)^4

h'(-1) = -1 - 10(10000)

h'(-1) = -1 - 100000

h'(-1) = - 99999
