Answer:
m + 8 ≥ -8
Step-by-step explanation:
<u>1st choice:</u> WRONG
m + 8 ≤ -8
-3 + 8 ≤ -8
5 ≤ -8
<u>2nd choice:</u> WRONG
-m + 8 ≤ -8
-(-3) + 8 ≤ -8
11 ≤ -8
<u>3rd choice:</u> RIGHT
m + 8 ≥ -8
-3 + 8 ≥ -8
5 ≥ -8
<u>4th choice:</u> WRONG
-m + 8 ≤ -8
-(-3) + 8 ≤ -8
11 ≤ -8
Turn 7.5% into a decimal. 7.5% = .075 or since this is money, .08 cents. Add everything together. Final answer is $37.58
<h3>Hello there!</h3>
This is a quite interesting problem.
Since it is normally unsolvable without the functions, the answer must lay somewhere in the examples given.
In this case, it lays in f(0).
Why would that be? Because anything times 0 is equal to 0.
In f(0), x is equal to 0, so a*x is therefore equal to 0.
Knowing that, the only thing that is left behind is, when you substitute in 0 for x:
16 = -(b*4)
Therefore, we can then solve to get:
-16 = b * 4
-4 = b
And now it's fairly simple to get a: just plug b into f(3) and solve.
25 = (3a) - (-4*4)
25 = 3a + 16
25 - 16 = 3a
9 = 3a
a = 3
And now to solve for what the question is looking for, just add a and b.
3 + -4 = -1
And there's your answer.
<h3>
a + b = -1</h3>
#1
Lies in 1st and image in 4th quadrant.
Total rotation quadrant=4-1=3
- Rotation angle=3(90)=270° and 360-270=90°
Reflection
#2
Total rotation=3-1=2
- Rotation angle=2(90)=180°
Symmetrical or linear
#3
One quadrant shift
<h3>Translational </h3>
We have our equation set up for us:
46-46*x=20
move 20 to the other side an then subtract
46*x=26
divide 46 on both sides
x = 26/46
simplify
x=
13/23 which is around
0.56521..
