How many solutions does this system of equations have?
y = -1/3x + 7
y = -2x^3 + 5x^2 + x - 2
Answers
Answer:
its one solution
Step-by-step explanation:
This system of equations have a unique solution.
What is a system of equation?A system of equations is a set or collection of equations that you deal with all together at once. For a system to have a unique solution, the number of equations must equal the number of unknowns.
For the given situation,
The system of equations are
y = -1/3x + 7 ------- (1)
y = -2x^3 + 5x^2 + x - 2 ------- (2)
Equation 1 is a linear equation and equation 2 is a polynomial equation.
So graph these two equations to find the solution.
The graph below shows the plotting of these two equations and
solution of these equations.
From the graph, it is clearly seen that this system of equation has only one solution.
Hence we can conclude that this system of equations have a unique solution.

Rob's first four test scores are 80, 85, 100 and 85. What does he have to score on the last test in order to have a test average of 90?
Answers
Answer:
100
Step-by-step explanation:
85 +80+100+85+x(the unknown),/the number of numbers ie 5
350+x/5=90
350+x=90 * 5
350+x=450
x=450-350
x=100
The score on the last test in order to have a test average of 90 is 100.
Given that, Rob's first four test scores are 80, 85, 100 and 85.
We need to find the score on the last test in order to have a test average of 90.
What is an average?By definition, an average is the arithmetic mean of the sum of all the values divided by the total number of values in a given set. An average is calculated for those sets of values which are more or less the same. The term average describes the numeric value that represents a large amount of data. An average can be derived by calculating the ratio of the sum of all the values to the number of units or values.
Let the score on the last test be x.
Now, average=(80+85+100+85+x)/5 =90
⇒350+x=450
⇒x=100
Therefore, the score on the last test in order to have a test average of 90 is 100.
