The answer for the exercise shown above is the second option, the option B, which is: B. In step 3, the addition property of equality was applied incorrectly.
The explanation is:
To solve this problem you must apply the proccedure shown below:. You have the followinwg equation:
<span>
4(m-3)+5(m+2)=m+9
Let's review the steps:
4m-12+5m+10=m+9 (step 1)
9m-2=m+9 (step 2)
8m =7 (step 3) (There is a mistake, because: 9m-m=9+2</span>⇒8m=11)
<span> m=11/8 This should be the step 4</span>
Answer:
part 3: add how ever many years that much money
Part 4:
Step-by-step explanation:
part 3:for instance 0years = 1,000$ to 5years so it equals 6,000$ and so on if you dont get it ask me
and its the same calculation each time
Part4: write about how much money you earned and if you can retire with that in the first box, and in the second, write about how you will most likely earn the money

Answer:
B. a reflection across X axis and then a dilation by a scale factor of 1.5
Step-by-step explanation:
As clear from the graph all the coordinates of image 2 are 1.5 times of image 1 so shape 2 is dilated by the scale factor 1.5.
It is evident from the graph that lines AO and A"O"are parallel to each other so shape 2 is the reflection of shape 1.
Now we calculate the magnitude of line AB
m1 = (y2-y1)/(x2-x1)
=(-3+6)/(-4.5=9)
=3/4.5
=1/1.5
=2/3
Next we calculate magnitude m2 of A"B"
m2= (2-4) /(-3+6)
=(-2/3)
Then we know Tan(180-∅) = -tan∅
similarly if m1=(-m2)
then the one line having magnitude m2 is the rotated image through X axis by 180° of the line having magnitude m1.
So the answer is B.
<h3>f(3)=8</h3>
Answer:
Solution given:
f(x)=ax^4-bx^2+x+5 and
f(-3)=2
f(-3)=a(-3)^4-b(-3)^2+(-3)+5
2=81a-9b-3+5
2=81a-9b+2
subtracting both side by 2 and adding 9b
2-2+9b=81a-9b+9b+2-2
9b=81a
now
f(3)=a(3)^(4)-b(3)^(2)+3+5
f(3)=81a-9b+8
substituting value of 81a
f(3)=9b-9b+8
f(3)=8
