Jermaine is solving the system of equations. $$y=6x+10$$ , $$y=-4$$ Jermaine says the system can be solved by using the equation $$y=6(-4)+10.$$ Is Jermaine correct, and why?

No. The equation should be $$-4=6x+10$$

Yes. The equation $$y=6(-4)+10$$ results in a solution of $$(-4,-14)$$

When solving a system of linear equations algebraically, Meredith obtained $$0=0$$ . How can Meredith interpret the results?

There are infinitely many solutions to the system.

The solution to the system is (0, 0).

This result is impossible, therefore Meredith made a mistake.

There is no solution to the system.

The graph of a function $$f(x)$$ is graphed on the classroom's chalkboard. Then the teacher asked the class where the function $$f(x-2)$$ is in relation to the original function. Which answer is correct?

$$f(x-2)$$ will be graphed two units to the right of the original function.

$$f(x-2)$$ will be graphed two units below the original function.

$$f(x-2)$$ will be graphed two units above the original function.

$$f(x-2)$$ will be graphed two units to the left of the original function.

Mike records the heights and arm spans of his classmates in the table shown. Mike plots the line-of-best fit as shown. Which statement describes why the line-of-best fit Mike draws is likely correct or incorrect?

The line-of-best fit is likely correct because it passes close to most of the data points.

The line-of-best fit is likely correct because it passes through the first and the last data points.

The line-of-best fit is not likely correct because the data points do not lie below the line.

The line-of-best fit is not likely correct because the data points do not lie above the line.

Consider the scatter plot shown. Which statement regarding the data in the scatter plot is correct?

The two variables have a strong negative correlation.

The two variables have a strong positive correlation.

The two variables have a weak negative correlation.

The two variables have a weak positive correlation.

Georgia did a project in which she measured the change in height (inches) that plants grew for different amounts of water (ounces) they were given each day. After one week, her data created the linear equation $$y=1.47x-2.43$$ to describe the correlation. What is the meaning of the slope in this equation?

For every additional ounce of water, her plants grow another 1.47 inches.

For every additional seed planted, 1 plant grows another 1.47 inches.

For every additional ounce of water, her plants grow another 2.43 inches.

For every additional inch a plant grows, it needs another 1.47 ounces of water.

A line was created that connects the amount of time spent studying and the grade that a student can expect to get on his or her final. What does it mean if the y-intercept is 67.2?

A student can expect to get about a 67.2 if he or she spends 0 minutes studying.

Any student can have a grade that is 67.2 points higher than his friend.

A student needs to spend at least 67.3 minutes studying to pass the final.

A student can expect that his or her grade will increase by 67.2 points for each minute him or her studies.

Mike records the heights and arm spans of his classmates in the table shown. Mike plots the line-of-best fit as shown. What is the correlation coefficient for the relationship between the variables, and does it suggest a strong correlation?

The correlation coefficient is 0.994, which suggests a strong correlation.

The correlation coefficient is 0.989, which suggests a strong correlation.

The correlation coefficient is 0.989, which suggests a weak correlation.

The correlation coefficient is 0.994, which suggests a weak correlation.

The table shows the time spent exercising and the number of calories burned. Which statement is true?

There is a very strong positive correlation between the time spent exercising and the number of calories burned.

There is a very weak negative correlation between the time spent exercising and the number of calories burned.

There is a very weak positive correlation between the time spent exercising and the number of calories burned.

There is a very strong negative correlation between the time spent exercising and the number of calories burned.

Use the information and table given to answer the question. Antonia is researching the growth of E. coli bacteria cells. She charts the population of cells present at given times in the table. Which statement best describes the change in population of E. coli bacteria cells?

The population growth of E. coli bacteria cells is best modeled by an exponential function because the population is increasing at a constant percent of change.

The population growth of E. coli bacteria cells is best modeled by a linear function because the population is increasing at a constant percent of change.

The population growth of E. coli bacteria cells is best modeled by an exponential function because the population is increasing at a constant rate of change.

The population growth of E. coli bacteria cells is best modeled by a linear function because the population is increasing at a constant rate of change.

Consider the functions shown in the tables. The function $$f(x)$$ represents the height of corn in inches after $$x$$ weeks. The function $$g(x)$$ represents the amount of an element present in grams after $$x$$ years. Which statement most accurately compares $$f(x)$$ and $$g(x)$$ ?

f(x) represents a linear function because there is a constant difference between consecutive terms, while g(x) represents an exponential function because there is a constant factor of change between consecutive terms.

f(x) represents an exponential function because there is a constant factor of change between consecutive terms, while g(x) represents a linear function because there is a constant difference between consecutive terms.

f(x) and g(x) both represent linear functions because there are constant differences between consecutive terms within both functions.

f(x) and g(x) both represent exponential functions because there are constant factors of change between consecutive terms within both functions.

Two functions are represented in the tables. Which description best matches the functions?

Function 1 is linear, while Function 2 is exponential.

Function 1 is exponential, while Function 2 is linear.

Both functions are exponential.

A baseball team has a budget of $300 to spend on baseball jerseys. The retail price of each jersey is $30, and the jerseys are available at 10% off the retail price. If there is a $3.00 flat-rate shipping fee for the order of any quantity of jerseys, which equation represents the number of baseball jerseys, x, the baseball team can order for exactly $300?

27x - 3 = 300

27x + 3 = 300

3x - 27 = 300

3x + 27 = 300
