Answer:
We can simplify everything to the power of 2:
[tex]8^{x+2} = 2^{3*(x+2)}=2^{3x+6[/tex]
[tex]16^{x+1} = 2^{4*(x+1)}=2^{4x+4[/tex]
As the two equations are equal to each other and they have common bases, their powers must be equal too. We can come up with this equation:
3x+6=4x+4
solve for x
x=2
D (last answer choice)
plug x=2 in and check and you will get 4096=4096

Answers
Multiply so there are no parentheses
5y-40y+16=-25y-46
Add 40y to both sides
5y+16=15y-46
Add 46 to both sides
5y+62=15y
Subtract 5y from both sides
62=10y
Divide both sides by 10
6.2=y
Why are there certain question where you multiply to a power and some you don't. Like tree diagrams. This is for probability of compound events.

Take for instance
P(A and B) = P(A) and P(B)
This gives
P(A and B) = P(A) * P(B)

Annika sells 6-inch pies for $5.00 and 8-inch pies for $9.00 each. Last week she sold twice as many 6 inch pies as she did 8-inch pies. She made $133.00 from her sales. Annika defined x as the number of 6 inch pies she sold and y as the number of 8-inch pies she sold. She wrote the system below.
6 x + 8 y = 133. 2 x = y.
Which statements about the system are true? Check all that apply.
1. Since the cost for each pie is $5 and $9, the first equation should be 5 x + 9 y = 133.
2. Since the 8-inch pies are 2 inches larger, the second equation should be x + 2 = y.
Since there are fewer 8-inch pies, the second equation should be x = 2 y to balance the values.
3. The first equation is correct because 6x represents the money earned for 6-inch pies and 8y represents the money earned for 8-inch pies.
Answers
Answer:
The number 3 is more accurate
Answer:
Since the cost for each pie is $5 and $9, the first equation should be 5x+9y=133
Since there are fewer 8-inch pies, the second equation should be x=2y to balance the values.

Option A, B, and D are true.
Explanation:
A coefficient is the number that is being multiplied by a variable. For example, in 7b, 7 would be the coefficient.
Terms are the numbers used in the equation. For example, in 3 + 2, 3 and 2 would be the terms.
3n and 5m are not coefficients as there are variables included. 3n and 5m are examples of a variable.
A constant is a number that is not multiplied by a variable. For example, in 8x + 3 + 2b, 3 would be the constant.

m = (6 -5)/(-4 -(-3)) = 1/-1 = -1
The y-intercept can be found from ...
b = y -mx
b = 5 -(-1)(-3) = 2
The slope-intercept equation for the line is ...
y = mx +b
