Answer:
#5) Its line “k”
Well to solve this you need to know what negative slopes are.
They decrease from height from left to right
And also a slope is always calculated like this
rise -> run
Think of it like a bed.
You have to wake up which means you have to rise and then you run to do whatever it is you gotta do.
Rise is going vertical and run is going horizontal.
So for line K you have it because since its negative its -3/1 so technically its -3 rise(basically fall since its negative), 1 run (right).
#6) 1/2 is the slope of line N. Or (c)
Well n is a potsive slope so we can automatically remove a and b.
And we can count like this, it started from the orgin it looks like (but you can use any given point really) and then just follow it, rise 1 and run 2. Rise 2 and run 3 doesn’t work so it has to be 1.2 or (c)
Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage rate of increase or decrease.

how did the Iraq war impact the united states
Answer: the Iraq war drained Billions of US dollars, putting us into debt we're still trying to get ourselves out of. and it was also one of the bloodiest wars with 4,500 American troops killed. saddam Hussain was also captured and convicted of war crimes.
Step-by-step explanation:
The Iraq war drained Billions of US dollars, putting us into debt we're still trying to get ourselves out of. and it was also one of the bloodiest wars with 4,500 American troops killed. saddam Hussain was also captured and convicted of war crimes.
We know that,
A Gallup poll made on behalf of CNN and USA Today concluded that 79% of Americans thought the Iraq War was justified, with or without conclusive evidence of illegal weapons. 19% thought weapons were needed to justify the war.
Under these assumptions, oil price increases from 2003-2008 due to the Iraq war reduced total U.S. income GDP by a total of approximately $274 billion, a direct transfer of about $124 billion and a further GDP effect of $150 billion.

I basically just have to find the angles but I also want to understand so if you could explain?
9514 1404 393
Answer:
c = 108°
d = 106°
Step-by-step explanation:
There are 2 basic rules involved here. From them, a number of others can be derived in order to simplify some calculations.
angles forming a linear pair are supplementary (total 180°)interior angles of a triangle total 180°The derived relations we can use in this problem are ...
vertical angles are congruentan exterior angle of a triangle is equal to the sum of the opposite interior angles__
cThe vertical angle to 78° is one of two remote interior angles with respect to exterior angle c. The other is the one marked 30°. That means ...
c = 78° +30* = 108°
__
dAngles d and 30° are two of the three angles in the largest triangle. The third is the vertical angle to 44°, so it is 44°. The sum of angles in that triangle is 180°:
d + 30° +44° = 180°
d = 180° -74° = 106°
The product of 0.4 and a number is 8.
Represent the statement as an equation. Use n for the variable. Determine the solution set using the replacement set .
how do you do that?
The equation that represents the statement is: 0.4n = 8
The value of variable n = 20
Recall:
Product represents multiplication.Thus:
Product of 0.4 and a number (n) is translated as 0.4 x n
Therefore,0.4 x n = 8
0.4n = 8
We need to find the value of the variable, n.
Solve for n by dividing both sides by 0.4.[tex]n = \frac{8}{0.4} \\\\\mathbf{n = 20}[/tex]
Therefore, the number that is multiplied by 0.4 to give 8, is: n = 20

Hannah was asked to make d the subject of the formula
d-7=4d+3/e
Finish her question.
Answer:
[tex]d = \frac{-1}{e} - \frac{7}{3}[/tex]
Step-by-step explanation:
In order to make d the subject of the formula, you need to isolate it.
- You started with d-7 = 4d + 3/e
- Move 4d to the left side by subtracting 4d from both sides to cancel it from the right so you have...
d - 7 = 4d + 3/e This will leave you left with -3d - 7 = 3/e
-4d -4d
- Then move over the -7 by adding 7 to both sides...
-3d - 7 = 3/e This will leave you left with -3d = 3/e + 7
+7 +7
- Finally to get d by itself divide both sides of the equation by -3 and you'll be left with...
[tex]d = \frac{3}{-3e} -\frac{7}{3}[/tex]
- You can cancel out the 3 in the -3/3e and make it -1/e so your final answer will be
[tex]d = \frac{-1}{e} - \frac{7}{3}[/tex]

Step-by-step explanation:
we start with the first and the third equations, as they have the same content structure.
we multiply the whole first equation by 2, so that the z terms become aligned, and then we add both equations :
-8x + 4z = 28
-2x - 4z = 22
--------------------
-10x + 0 = 50
x = -5
-2x - 4z = 22
-2×-5 - 4z = 22
10 - 4z = 22
-4z = 12
z = -3
y = x + z + 12
y = -5 - 3 + 12 = 4
