Answer:
c
Step-by-step explanation:
Try to find ways that you can easily remember formulas. For example, when you find the line of symmetry the equation is y=-b/2a. A way you can remember that is by saying negative tuba. It seems silly but it’s something you can do for most equations so it doesn’t seem so intimidating.
Answer:
21 adults and 139 children
Step-by-step explanation:
x=adult (8$)
y=child (5$)
8x + 5y =863
x+y=160
-x -x (subtract x on both sides)
y= -x + 160
plug that in for y on the other equation
8x + 5(-x + 160) =863
distribute 5 to both
8x + -5x + 800 = 863
combine both x values
3x + 800 = 863
-800 -800 (subtract on both sides)
3x = 63
divide by 3 on both sides
x = 21 adults
now plug x in one of the equations
21 + y = 160
-21 -21
y=139 children
t = 30a + 150 .
' t ' is the total cost of treatment.
' a ' is the number of appointments.
The $150 is paid only once.
I hope Pedro gets better fast. Poor little guy.
______________________________________
Oh, I see.
Now you're saying that she pays the $150 at every appointment.
So the equation is actually

1.
was moved 4 units right and 1 unit down
2.
was moved 3 units up
3.
was moved 6 units right, scaled down along the y-axis 4 times and moved 8 unit up
4.
is moved 3 units right, reflected over the x-axis and moved 2 units up
