Step-by-step explanation:
slope = -9
y - -4 = 9(x - 2)
y+ 4 = 9x -18
y = 9x - 22
Answer:
B
Step-by-step explanation:
f(x)= -3(x+1)^2 +2
> -3, Has to negative because its facing down
>(x+1) means it goes to the left 1 unit
> +2 at the end means it goes up by 2 units
Answer:
Step-by-step explanation:
(a+b)(a-b)=a^2-b^2
Answer:
12 fives and 18 tens
Step-by-step explanation:
solving this we need 2 different equations
one for he total bills and one for the total money
x+y=30
that is total bills
5x+10y=240
combining both equations we can use elimination method and get
12 five dollar bills and 18 ten dollar bills
If we have a circle with a radius of 3 we need to find the diameter of the circle. Remember radius is half of the diameter. So, the diameter is 6 units.
Use the circumference formula: C=3.14D
C=3.14(6)
C=18.84 units
