Answer:

x=-4, y=2. (-4, 2).

Step-by-step explanation:

5x+6y=-8

-2x+8y=24

-----------------

2(5x+6y)=2(-8)

5(-2x+8y)=5(24)

-----------------------

10x+12y=-16

-10x+40y=120

---------------------

52y=104

y=104/52

y=2

5x+6(2)=-8

5x+12=-8

5x=-8-12

5x=-20

x=-20/5

x=-4

Hello,

I suppose a and b are vectors
and i and j unit's vectors

$\vec{i}*\vec{i}=1\\
\vec{j}*\vec{j}=1\\
\vec{i}*\vec{j}=0\\
$
$\vec{a}\ .\ \vec{b}=(4\vec{i}\ +3 \vec{j}).(-4\vec{i}\ +4 \vec{j})\\
=-16-3*4*0+4*4*0+12=-4$

Hi! I don't understand the attached question and already attempted to solve it. Can someone help me and explain how to solve it?

The range is the difference between the highest number and the lowest number.

The highest number would be 67, the lowest number is 43.

The range is 67 - 43 = 24
