The answer is 2 and negative 9
Hi there
First we need to find the rate of increases
551.25=500 (1+r)^2
Solve for r
First divide each side by 500 to get
551.25/500=(1+r)^2
And take the square root for both sides to get
(551.25/500)^ (1/2)=1+r
(Note that the square root is the same as the power of 1/2)
After that subtract each side by -1 to get
R=(551.25÷500)^(1÷2)−1
R=0.05
Since we have the rate of increases the formula is
Y=500 (1+0.05)^x
Y=500 (1.05)^x ....answer
Good luck!

Answer:
D -13/35 ( negative 13/35 )
Step-by-step explanation:
4/5 + x = 3/7
Convert to equivalent fractions with a common denominator:
28/35 + x = 15/35
Subtract 28/35 from both sides
x = - 13/35
