Can someone help me with this please

a) 10mm each second.

b) 2 in a increasing correlation.

Step-by-step explanation:

a) we want to look at 1 and 2 seconds to recognise the increase.

1 second it reachs 10mm

2seconds it reachs 20mm

20mm-10mm=10mm

This means each second its increasing by 10mm

B) Rise / Run

our two coordinates will be (1,10) and (2,20)

the run is when it goes across, which will be 1

and the rise will be 2

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
