First Simplify the numbers we know. Therefore we get: x2=75/3 which is the same as x2=25

Now find the square root of 25, which is 5 or -5. Therefore x=5 or -5

3x²=75. What is x?

$\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}$

First, divide by 3 on both sides:-

x²=25 Next, take the square root of both sides:-

x=5, x=-5 (remember, x² =x times x (x times itself); 5 times itself gives 25, and -5 times itself also results in 25)

Find the slope of the line that passes through the following points: (5, 3) and (-2, -4)

Aleksandr [31]

Answer:

Step-by-step explanation:

To find the slope, you must subtract the second y axis from the first y axis then the second x axis from the first x axis.

Problem: (5, 3) (-2, -4)

Solution: Step 1. - 4 - 3 = 7 (subtract the second y axis from the first y axis)

Step 2. - 2 - 5 = 7 (subtract the second x axis from the first x axis)

Which graph best represents the feasibility region for the system shown above? ( pics are in this)

zalisa [80]

Consider the system of inequalities

$\left\{ \begin{array}{l} y\ge 2 \\ x\le 6 \\ y\le 3x+2 \\ y\le -x+10. \end{array}\right.$

1. Plot all lines that are determined by equalities (see attached diagram)

$\left\{ \begin{array}{l} y=2 \text{ (red line)} \\ x= 6 \text{ (blue line)}\\ y=3x+2 \text{ (green line)} \\ y= -x+10 \text{ (orange line)}. \end{array}\right.$

2. Determine which bounded part of the plane you should select:

$y\ge 2$ means that you should take points with y-coordinates greater than or equal to 2 (top part of the coordinate plane that was formed by the red line);
$x\le 6$ means that you should take points with x-coordinates less than or equal to 6 (left part of the coordinate plane that was formed by the blue line);
for $y\le 3x+2$ you can check where the origin is placed. Since $0\le 3\cdot 0+2$ , the origin belongs to the needed part and you have to take the right part of the coordinate plane that was formed by green line.
for $y\le -x+10$ you can check where the origin is placed. Since $0\le -1\cdot 0+10$ , the origin belongs to the needed part and you have to take the bottom part of the coordinate plane that was formed by orange line.
