Answer: $ 0.146 per year.
Step-by-step explanation:
Given: Average price of gas in 2000 = $1.57 per gallon
Average price of gas in 2005 = $2.30 per gallon
The rate of change for each year between 2000 to 2005
= 
Hence, the rate of change for each year between 2000 to 2005 is $ 0.146 per year.
Hi there! Thanks for asking a question here on Brainly.
Step 1: We need to simplify both sides of the equation.
⚫ <span><span><span><span>5a</span>−15</span>+<span>9a</span></span>=<span><span>3a</span>+29
</span></span>⚫ <span><span><span><span><span>5a</span>+</span>−15</span>+<span>9a</span></span>=<span><span>3a</span>+29
</span></span>⚫ <span><span><span>(<span><span>5a</span>+<span>9a</span></span>)</span>+<span>(<span>−15</span>)</span></span>=<span><span>3a</span>+29
</span></span>
Combine like terms
⚫ <span><span><span>14a </span>+<span>15 </span></span>= <span><span>3a </span>+ 29
</span></span>⚫ <span><span><span>14a </span>− 15 </span>= <span><span>3a </span>+ 29
</span></span>Step 2: Subtract 3a from both sides.
⚫<span><span><span><span>14a </span>− 15 </span>− <span>3a </span></span>= <span><span><span>3a </span>+ 29 </span>− <span>3a
</span></span></span>⚫<span><span><span>11a </span>− 15 </span>= 29
</span>Step 3: Add 15 to both sides.
⚫ <span><span><span><span>11a </span>− 15 </span>+ 15 </span>= <span>29 + 15
</span></span>⚫ <span><span>11a </span>= 44
</span>Step 4: Divide both sides by 11.
⚫ 11a11= 4411
a = 4

Answer:
A = $2130.49
Step-by-step explanation:
Given the following data;
Time, t = 5 years
Interest rate, r = 8%
Principal = $1450
To find the future value, we would use the compound interest formula;
Where;
A is the future value.
P is the principal or starting amount.
r is annual interest rate.
t is the number of years for the compound interest.
Substituting into the equation, we have;
A = $2130.49
Answer:
2x squared - 8
Step-by-step explanation:
For this kind of equation, we use the distributive property
So in the image below I used a box method (that's how I learned it in school)
So since -4x and 4x cancel each other out, or amount to 0, we don't put anything for those. So the equation left is 2x squared - 8
