1. Refer to the equation 3x - 2y = -18 Complete the table of values for at least 2 points. Show your work.Use the table of values to graph the line.

2. Use the equation y = 4x to answer the questions. Graph y = 4x.
What is the slope of y = 4x and what does this mean?

Answers

Answer 1
Answer:

Part 1

For the given equation 3x-2y=-18, complete the table:

1) when x=0, then

3\cdot 0-2y=-18,\n -2y=-18,\n y=9;

2) when y=0, then

3x-2\cdot 0=-18,\n 3x=-18,\n x=-6;

3) when x=2, then

3\cdot 2-2y=-18,\n -2y=-24,\n y=12;

4) when x=4, then

3\cdot 4-2y=-18,\n -2y=-30,\n y=15.

Therefore, the table is

\begin{array}{ccccc}x&0&2&4&-6\ny&9&12&15&0\end{array}

With these data you can plot the graph of the function (see 1st diagram).

Part 2

The graph of the function y=4x is represented in the second diagram. The slope of the line is m=4.

The qustion is what is the greatest common factor of 24,56 and 72

Answers

The greatest common factor will be 8.

What is common factor? What is a mathematical equation? What is Probability?

  • A common factor is a whole number which is a factor of two or more numbers. The highest common factor (HCF) is the greatest factor that will divide into two or more numbers. The lowest common multiple(LCM) is the smallest multiple that is common to two or more numbers.
  • A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
  • A mathematical equation is used to equate two expressions.
  • Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have three numbers 24, 56 and 72.

The factors of 24 are : 1, 2, 3, 4, 6, 8, 12, 24

The factors of 56 are : 1, 2, 4, 7, 8, 14, 28, 56

The factors of 72 are : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

Therefore, the greatestcommon factor will be 8.

What is the value of tanΘ in the unit circle below?

Answers

from the picture, we can see the pair, bear in mind that terminal point pair is really the (x,y) pair or namely the (cosine, sine) pair, so we know what the cosine and sine are.

\bf tan(\theta )=\cfrac{\stackrel{sine}{\quad (1)/(2)\quad }}{\stackrel{cosine}{(√(3))/(2)}}\implies \cfrac{1}{2}\cdot \cfrac{2}{√(3)}\implies \cfrac{1}{√(3)}\implies \stackrel{\textit{rationalizing the denominator}}{\cfrac{1}{√(3)}\cdot \cfrac{√(3)}{√(3)}\implies \cfrac{√(3)}{3}}

Answer:

D

Step-by-step explanation:

We can use the "vertical line test" to determine whether a given graph represents a function or not.  

If your vertical line intersects the graph in more than one place, the graph does NOT represent a function.  Thus, D does not represent a function, as a line drawn vertically thru this graph intersects the graph multiple times.

Graph A:  Note that if you draw a vertical line thru x = -2, your line will intersect the BLACK dot (-1 3/4, 0) and the EMPTY circle (-1 3/4, 3 1/4).  This is OK; this graph represents a function.
