Answer:
The answer is
Step-by-step explanation:
To solve the expression we use the rules of indices
Since the bases are the same and are dividing we subtract the exponents
That's
So we have
We have the final answer as

Answer:40001
Step-by-step explanation:
C. Distributive Property
D. Inverse Property of Multiplication
E. Commutative Property of Addition
The properties that can be used to solve 7y - 15 = -29 are
Addition property of equality and inverseproperty of multiplication.
Given equation is 7y - 15 = -29.
We will solve for y and see which of the given following properties are applied.
Addition property of equality
If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal.
Inverse property of multiplication
It states that every non-zero x multiplied with 1/x will equal 1.
Solve for y.
7y - 15 = -29
We will add 17 on both sides of the equation.
7y - 15 + 15 = -29 + 15
7y = -14
Now, multiply 1/7 into both sides of the equation.
7y / 7 = -14 / 7
y = -2
While solving for y we see that we have to use the addition property of equality and inverse property of multiplication.

Answer:
A and E
Step-by-step explanation:
Other 2 wouldn't make sense
Only definite of A
Addition Property of Equality ----If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal.
Commutative property of addition- changing the order of the numbers we are adding, does not change the sum. Here's an example of how the sum does NOT change, even if the order is changed
To find the equation for the linear function representing the sales, we need to find the slope (m) and the y-intercept (b).
The slope, m, can be calculated using the formula: m where (x1, y1) and (x2, y2) represent points on the line. Using the given data,
and
we have: m =
Substituting one of the points, say (1983, $990,000), into the equation y = mx + b, we can solve for b:
Therefore, the equation representing the sales is: y . To estimate the sales in 1991, we substitute x = 8 (since 1991 corresponds to x = 8) into the equation: y
Therefore, the estimated sales for 1991 would be approximately $5,534,000.
