-2a - 4 > -8
add 4 to both sides

-2a - 4 + 4 > -8 + 4
-2a > -4

divide both sides by -2 AND change the direction of the sign because we're dividing by a negative

a < 2

ANSWER: a < 2

Hope this helps! :)

Hey there!

Firstly, we have to “add” the number “4” on each of your sides

Like: -2a -4 + 4> -8 +4
Cancel: -4 + 4 because it will give you “0”
Keep: -8+4 because it gives you “-4” and we have paid it off with -2a

Like: -2a>-4

Divide each of the sides by “-2”

Like: -2a/2 > -4/-2

Cancel: -2a/2 because it gives us “1”

Keep: -4/-2 because that’ll give us the answer on the left side of the inequality

So, a < 2 would be your answer

Good luck on your assignment and enjoy your day

Write the slope-intercept form of the equation that passes through the point (4,-6) and is parallel to the line y = -3/4x - 5
Karolina [17]

The equation that runs through the location (4,-6) has the slope-intercept form,  y=-\frac{3}{4}x-3 .

<h2>Formation of the equation</h2>

A line's equation written in the slope-intercept form:

y=mx+b

where m= slope & b= y-intercept

The slope of two parallel lines is equal.

Currently, we know the line's equation:

y=-\frac{3}{4} x-5

here, slope, m= -\frac{3}{4}

A line equation is created by adding the slope's value and the point's coordinates (4, -6):

-6=-\frac{3}{4}(4)+b

⇒ -6=-3 +b [adding 3 to both sides]

⇒-3=b

⇒b= -3

Hence the solution is  y=-\frac{3}{4}x-3 .

What is the length of Line segment A C? 3 ft 4 ft 9 ft 18 ft
AfilCa [17]

Answer:

By the given diagram,

AM = MB and CN = NB

M and N are the mid points of the sides AB and CB respectively,

Thus, by the mid point theorem,

MN ║ AC,

By the alternative interior angle theorem,

∠BMN ≅ ∠BAC

∠BNM ≅ ∠BCA

Thus, by AA similarity postulate,

ΔBMN ≅ ΔBAC

By the property of similar triangles,

Thus, The length of AC is 18 ft.
