Answer:

Check attached graph

Step-by-step explanation:

Given inequality is $-2a-5>3$ .

Now we need to graph the given inequality to find the correct choice.

$-2a-5>3$

$-2a-5+5>3+5$

$-2a>8$

$-\frac{2a}{-2}$

$a$

that means line will go on the left side of -4.

since we have <, so there will be an open circle at -4.

Hence final graph of the given problem looks like:

-2x-7≥41 in algaebra for

dexar [7]

Answer:

They are equal. x= -24

Step-by-step explanation:

-2x - 7 ≥ 41

First you isolate the variable

-2x -7 ≥ 41

+7 +7

-2x≥48

then divide each side by -2

x≥-24

Then go back and plug in

-2(-24)-7=

48-7=41

Therefore

41=41

The coordinates of the 3 of the vértices of a parallelogram are (-7, 3), (-6, 1), and (-4, 5). What is the equation for the line

Natali [406]

We know, opposite sides are parallelogram is parallel, therefore slopes are equal.

Slope of line one :

$m=\dfrac{-7-(-6)}{3-1}\\\\m =\dfrac{-1}{2}\\\\m= -0.5$

So, equation of other line passing through (-4,5) and have slope of -0.5 is :

y-5 = -0.5( x-(-4))

y-5 = -0.5x - 2

y + 1/2x = 3

2y + x = 6

Therefore, equation of line containing the (-4, 5) is 2y + x = 6.

Hence, this is the required solution.
