Answer:

Step-by-step explanation:

x-3 = 0

x = 3

x + 4 = 0

x = -4

x - 2 = 0

x = 2

x = 3, -4, 2

Suppose that W and X are points on the number line. If WX=9 and W lies at 12, where would X be located? If there is more than on

Reika [66]

X = 3/4
Because WX=9 and W=12
12X=9
X=9/12 or 3/4

Helppp lol<br><br>which system of linear equations is represented by the graph?

kondaur [170]

Answer:

<em>y ≥ x - 2, and x + 2y < 4 ; Option C</em>

Step-by-step explanation:

Consider the y - intercept and slope of 1 of these given lines,

$y - intercept = ( 0, - 2 ) / - 2\\slope = 1 / 1 = 1$

From this we can formulate the equation of 1 line;

$Take Equation In the Form - y = ax + b, a - slope, and , b - y intercept,\\y = ax + b, a = 1, b = - 2,\\Equation of Line 1 - y = x - 2$

Now consider the y - intercept and slope of the remaining line;

$y - intercept = ( 0, 2 ) / 2\\slope = 1 / - 2 = - \frac{ 1 }{ 2 }$

This creates a line with the equation as such;

$Take Equation In the Form - y = ax + b, a - slope, and , b - y intercept,\\y = ax + b, a = - 1 / 2, b = 2,\\Equation of Line 1 - y = - \frac{ 1 }{ 2 } x + 2, x + 2y = 4$

From this we see that the solution of the system is such;

<em>Solution ; y ≥ x - 2, and x + 2y < 4 ; Option C</em>

Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?

Eduardwww [97]

Answer:

2 4/36

Step-by-step explanation:

To do this, multiply the whole number by the denominator and add it to the numerator.

8 x 9 = 72

72 + 4 = 76

76/9

<em>Then multiply across (multiply numerators with numerators; denominators with denominators)</em>

76 x 1 = 76

9 x 4 = 36

76/36 = 2 4/36

____________________________

<em>A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.</em>

1/4 x 8/1 = 8/4 = 2

1/4 x 4/9 = 4/36

= 2 4/36
