Step-by-step explanation:

The solution is where both graph cross each other.

Is the solution, the point (x, y) that they gave you, the same point as where the two graph cross each other?

If yes then the solution is correct.

If no then the solution is wrong.

Find the solution of y=-3x - 1 for x = -5.

Serjik [45]

Answer: A. (-5,14)

Step-by-step explanation: Since you have already been given the value of x, which is -5, you can insert that into the equation to find y, as $-3(-5)-1$ results in 14.

Jack and Jane are married and both work. However, due to their responsibilities at home, they have decided that they do not want

Zanzabum

To solve a system of inequalities we graph both of them.
The inequality representing their combined pay would be
$12.50x+10.00y \geq 750$ . This is because Jane makes 12.50/hr, Jack makes 10.00/hr, and they want to make at least, so greater than or equal to, $750 combined.
The inequality representing their combined hours working would be
$x+y \leq 65$ , since they do not want their combined hours to be over 65. In both of these inequalities, <em>x</em> represents the number of hours Jane works and <em>y</em> represent the number of hours Jack works.
To graph these, we solve both of them for <em>y</em>:
$x+y \leq 65
\\ x+y-x \leq 65-x
\\ y \leq 65-x$
$12.50x+10.00y \geq750
\\12.50x+10.00y-12.50x \geq 750-12.50x
\\10.00y \geq 750-12.50x
\\ \frac{10.00y}{10.00} \geq \frac{750}{10.00} - \frac{12.50x}{10.00}
\\y \geq 75-1.25x$
The attached screenshot shows what the graph looks like. Going to the point where they intersect, we see that the shaded region that satisfies both inequalities begins when Jane works 40 hours and Jack works 25.

DATA ANALYSIS AND STATISTICSProbabilities involving two rolls of a dieAn ordinary (falr) die is a cube with the numbers 1 throug

Zepler [3.9K]

Solution

The table below is the required sample space of the to fair die

From the above table

The sample space contain 36 outcomes

Event A: The sum is greater than 9

we will look at the table and count all the elements that are greater than 9

There are 6 elements (they are 10, 10, 10, 11, 11, 12 from the table)

The probability for event A will be

$\begin{gathered} p(A)=\frac{\text{required outcome}}{\text{total outcome}} \\ p(A)=\frac{6}{36} \\ p(A)=\frac{1}{6} \end{gathered}$

P(A) = 1/6

Event B: The sum is an even number.

We will look at the table and count the number of elements that are even

There are 18 elements (notice that there are 3 even number on each of the 6 rows of the table)

The probability for event B will be

$\begin{gathered} p(B)=\frac{\text{required outcome}}{\text{total outcome}} \\ p(B)=\frac{18}{36} \\ p(B)=\frac{1}{2} \end{gathered}$

p(B) = 1/2
