Answer:
<u>x= -7 , y= 9</u>
Steps:
4x+3y=-1
5x+4y=1
First, multiply the top equations by -5, and the bottom by 4 to get :
-20x-15y=5
20x+16y=4
Then, you’re going to add the two equations with them being on top of each other so you can easily see what cancels out :
-20x-15y=5
+ 20x+16y=4
———————
0+1y=9
From this, you get :
y=9
Now that you have one variable, find x by substituting 9 for y in one of the equations, I choose :
4x+3y=-1
So :
4x+3(9)=-1
Then simplify by multiplying 3 and 9 :
4x+27=-1
Then subtract 27 on each side :
4x=-28
Then, divide by 4 to get that :
x= -7
Hope this helps!!
Might be 134 because since angle 2 and 8 are lined up like that it is same side exterior angles which means they are supplementary from each other so they will equal 180. So I did 180-46 to get 134, I’m not sure if I’m correct
Answer:
Option C g(x)= (x+5)^2 is correct
Using the slope concept, it is found that the distance from point A to point B is of 392 feet.
<h3>What is a slope?</h3>
- The slope is given by the <u>vertical change divided by the horizontal change</u>.
- It's also the tangent of the angle of depression.
At point A:
- The vertical change is of 108.
- The horizontal change is the position
, that we want to find.
Hence:
At point B:
- The vertical change is of 108.
- The horizontal change is the position
, that we want to find.
Hence:
Then, the distance is:
The distance from point A to point B is of 392 feet.
