What’s the graph answers

Mathematics
1 answer:
Naya [18.7K]3 years ago
4 0

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

-x-2y=-10    <em>add x to both sides</em>

-2y=x-10     <em>divide both sides by (-2)</em>

y=-\dfrac{1}{2}x+5

It's a linear function.

We need only two points to plotting a graph.

We choose any three values of x and calculate y.

\for\ x=0\to y=-\dfrac{1}{2}(0)+5=0+5=5\to(0,\ 5)\\\\for\ x=4\to y=-\dfrac{1}{2}(4)+5=-2+5=3\to(4,\ 3)\\\\for\ x=6\to y=-\dfrac{1}{2}(6)+5=-3+5=2\to(6,\ 2)

2x - 4(x + 2) = -2X-8
devlian [24]

Answer:

x= 0

Step-by-step explanation:

in order to find the value of x in the 2x - 4(x + 2) = -2X-8

we are going to apply bodmas rule by first opening the bracket

we have,

2x-4x-8 = 2x -8

we proceed to collect the like terms

2x -4x-2x = -8 +8

-4x = 0

divide both sides by -4

-4x/-4 = 0/-4

x= 0

The solution set of x(x-5) is greater than or equal to 0 is
kompoz [17]
Solve x(x-5)=0; the roots are 0 and 5.

Draw a number line.  Plot 0 and 5 on this line.  
Set up 3 intervals, as follows:  (-infinity, 0), (0, 5), and (5, infinity).

Now choose a test number from within each interval (e. g., -2, 3, 10).

Subst. each into the inequality x(x-5)\geq 0.  In each case, determine whether the inequality is true or false.  

Based upon your results here, you should be able to determine on which interval or intervals the inequality is true.  Those interval(s) is/are your solution set.
