Answer:
D) the system has no solution.
Step-by-step explanation:
A student is solving a system of equations by substitution and comes up with the solution -3=2.
So, the unknown variables are canceled out and there are only numbers in the equation but -3 ≠ 2.
If we assume that she solved the problem correctly, then there will be no solution for that system of equations because there is no variable remaining in the final equation to solve for. (Answer)

Step-by-step explanation:
When there as a remainder, polynomial division does not result in a polynomial. The set of polynomials is not closed for <em>division</em>.
Answer:
15^3=15×15×15=3375
0^4=0×0×0×0=0
5^5=5×5×5×5×5=3125
3.5^2=3.5×3.5=12.25
6^5=6×6×6×6×6=7776
7^4=7×7×7×7=2401
1^8=1×1×1×1×1×1×1×1=1
2.5^3=2.5×2.5×2.5=15.625
Step-by-step explanation:
The linear function that is modeled by the table is given by:
y = -5x - 3.
<h3>What is the complete problem?</h3>
The problem is incomplete, and was not found on a search engine, but one idea is to find a linear function that models the data in the table.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For this problem, we have that when x increases by 3, y decays by 15, hence the slope is given by:
m = -15/3 = -5.
Hence:
y = -5x + b.
When x = 1, y = -8, hence we use it to find b as follows:
-8 = -5(1) + b
b = -3.
Hence the function is:
y = -5x - 3.
