Harlamova29_29 [7]

Answer:

C

Step-by-step explanation:

A) not true. Sin A = some decimal

Cos 720 = 1

D) That means that d is not true either. not true

B) Sin55 = cos55 is not true either only sin(45) = cos(45) is true. So B is not true.

That leaves C. I think if you check it, you'll find it is right. sin(A) = cos(90 - A)

In at least five (5) sentences, explain the effects of changing the “m" and the "b" in y=mx+b.
victus00 [196]
Changing the “m” or “b” would change the overall line on the graph. Meaning the line could be steeper or flatter. It could also change whether the line has a positive slope or negative. Likewise, when you use negative numbers for the m, the line will have a negative slope and will have a decreasing look to it. When you use negative numbers for the b, the y-intercept will be negative which will put the line further down the y-axis.

I hope this is what you were looking for! I kinda did it off the top of my head so of course feel free to change anything!!

vitfil [10]

Answer:

Step-by-step explanation:

Y= the total ammount she pays.

X= the number of games she wants to play.

$7 for the "shoes" and $3 for each game she wants to play

7+(3*4)= Y

7+12= $19

$73 = 3x + 7

 -7           -7

$66 = 3x

66/3 = 3x/3

 22  =  x

x=22
