Answers
Answer:
40x=120
10r=130
Step-by-step explanation:
8(5x=15-5y)= 40x=120-40y
5(8y+26=2r)= 40y+130=10r
40x=120-40y
10r=130+40y
40x=120
10r=130

Write the equation g(x) of the transformation of the parent graph f(x) = |x| translated right 5 units.
Answers
Answer:
g(x) = |x-5|
Step-by-step explanation:
f(x) = |x|
y = f(x + C) C < 0 moves it right
g(x) = |x-5| moves it to the right 5 units
We start off with: f(x) = |x|
c < 0 means move right
y = f(x + c)
Move 5 units to the right
After: g(x) = |x - 5|
Best of Luck!

In 1979, zoologists estimated the number of fish in a local pond to be about
540. In 1989, 10 years later, the zoologists estimated that the number of
fish had increased to 990. Assuming that the fish population increased
linearly, how many fish lived in the pond in 1986? *
ann
Answers
Answer:
693 fish
Step-by-step explanation:
In 10 years, we can tell that the amount of fish increased by 1.833...(990 divided by 540) times. If we divide 1.833... by 10, we can find how much the pond increases by yearly. we get 0.1833... If we multiply that by 7 (because the gap between 1986 and 1979 is 7 years), we get 1.2833... So, if we multiply 540 by 1.28333..., we get 693 fish.

Answers
g(x) = -(x + 1)^2 - 3
Let's simplify this equation
g(x) = -(x^2 + 2x + 1) - 3
Distribute the negative sign

Combine like terms
g(x) = -x^2 - 2x - 2

When you reflect a point over the y-axis, the sign of the number changes. It goes from negative to positive and positive to negative. Since both our numbers are positive, only the y-coordinate become negative because it is only being reflected over the y-axis, not x-axis. (6,-10)

Aaron puts $1,000 in an account that pays 10% interest compounded quarterly. He leaves it in the account for six months. Estimate how much interest he earns.
Answers
Answer: $50.63 --- Interest
Step-by-step explanation:
Step 1
Using the formulae
A = P(1 + r/n)^nt
Where
A = principal + interest Amount
P = Principal Amount = $1000
t = Time in years= 6months = 0.5 years
n = number of compounding periods= quarterly =4
Step 2
6 months = 6/12 = 0.5 years
Rate = 10 % = 0.1
A = P(1 + r/n)^nt
= 1000 ( 1 + 0.1/4)^(4 x 0.5)
=1000(1 +0.025)^2
= 1000(1.025)^2
= 1000 x 1.050625
A= $1,050.625
but A = principal + interest Amount
Interest = A- Principal=$1,050.625-$1,000
=$50.625
