Help please Marcie heated a beaker of water in science class. The scatter plot shows the temperature (y), in degrees Celsius, of the water based on the number of minutes (x) she heated the water.

Part A: The line of best fit for this data is
y = 5.3x + 23. Use this equation to make a conjecture about the temperature of the water in the beaker if heated for 6 minutes.

A.
The water will be about 71⁰C.

B.
The water will be about 55⁰C.

C.
The water will be about 32⁰C.

D.
The water will be about 50⁰C.

Part B: What is the y-intercept in the line of best fit? What does the y-intercept represent in the scatter plot?

A.
5.3; the amount the temperature increases each minute

B.
5.3; the temperature of the water before it is heated

C.
23; the amount the temperature increases each minute

D.
23; the temperature of the water before it is heated

Write the expression 7x^3-28xy^2 as the product of 3 factors

Use the elimination method to solve the systems of equations.choose the correct ordered pair. 7x+4y=39

Asystem of linear equations with more equations than unknowns is sometimes called an overdetermined system. can such a system be consistent? illustrate your answer with a specific system of three equations in two unknowns. choose the correct answer below. a. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 6 b. no, overdetermined systems cannot be consistent because there are fewer free variables than equations. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 12 c. yes, overdetermined systems can be consistent. for example, the system of equations below is consistent because it has the solution nothing. (type an ordered pair.) x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 8 d. no, overdetermined systems cannot be consistent because there are no free variables. for example, the system of equations below has no solution. x 1 equals 2 comma x 2 equals 4 comma x 1 plus x 2 equals 24
