So, basically what I did was to split all of the surfaces up and find them one by one. After that, I just add all of them up.
Area of A= 5×6=30 cm²
Area of B= 3x6=18 cm²
Area of C= 4x6=24 cm²
Area of 2D= ½x3x4x2=12 cm²
Total surface area= 30+18+24+12=84 cm²

Step-by-step explanation:
To find g-¹( 2) we must first find g-¹(x)
To find g-¹(x) equate g(x) to y
That's
y = g(x)
We have
y = - 2x + 7
Now interchange the terms that's x becomes y and y becomes x
We have
x = - 2y + 7
Make y the subject in order to find g-¹(x)
Move 7 to the left side of the equation
- 2y = x - 7
Multiply both sides by - 1
We have
2y = 7 - x
Divide both sides by 2 to make y stand alone
That's
<h3>
</h3>
So we have
<h3>
</h3>
Now to find g-¹(- 2) substitute the value of x that's - 2 into the expression
We have
<h3>
</h3>
We have the final answer as

</h3>
Hope this helps you
Answer:
3.68
Step-by-step explanation:
A.) 200+15m=395. This is because the initial price is 200, and after that she will add $15/month. The equation you chose would be exponential, meaning the rate would increase as time passed, which is not the case. Instead, the rate is constant, and the only think that changes is m, the number of months.
b.) I believe it will be easier to answer with ^this equation.
c.) The rate of change would be 15, since the rate is increasing monthly by $15.
d.) Once you solve 209+15m=495, you'll have the answer.
Answer:
Answer is 28/4 = 7
Step-by-step explanation:
Given
Beth B = 28 problem
B has 4 times more problem than Mery m
Find
Total number of problem Mery m has if Beth has 4 times more problem than Beth
So,
B = 4 x m
m = B/4 = 28/4 = 7
Finally answer (d) is correct which is 28 ÷ 4 = m
