3.4-2.8d+2.8d-1.3 Combine like terms

vovikov84 [41]

Answer: 2.1

Step-by-step explanation:

3.4 - 2.8d + 2.8d - 1.3

add the variables together and the coefficients or add the d's with d's and 3.4 with 1.3

= 3.4 - 1.3 = 2.1

=2.8d - 2.8d = 0

The final answer would be 2.1

2) -4x – 6(3x + 4) = -4 + 8(1 - x)

likoan [24]

Answer:

x=-2

Step-by-step explanation:

-4x – 6(3x + 4) = -4 + 8(1 - x)

Distribute

-4x – 18x -24 = -4 + 8 -8x

Combine like terms

-22x -24 = 4-8x

Add 22x to each side

-22x+22x -24 = 4-8x+22x

-24 =4+14x

Subtract 4 from each side

-24-4 = 4+14x-4

-28 = 14x

Divide each side by 14

-28/14 =14/14

-2 =x

What is the distance of the line?<br> Remember the distance formula is (23 - 23) + (42 -

vivado [14]

Answer:

<em>The distance of the line is 10.82</em>

Step-by-step explanation:

Distance Between two Points in the Plane

Given two points A(x1,y1) and B(x2,y2), the distance between them is:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The graph clearly shows the points (-5,4) (4,-2), thus the distance is:

$d=\sqrt{(4-(-5))^2+(-2-4)^2}=\sqrt{9^2+(-6)^2}$

$d=\sqrt{81+36}=\sqrt{117}=10.82$

The distance of the line is 10.82
