Answer:
Question 1. If the perimeter of Rectangle ABCD is 34y+2. What is the width?
Question 2. What is the area of Rectangle ABCD in terms of y?
Question 3. If the perimeter of the rectangle is 70. What is it’s area?
Question 4. What are the length and width of the rectangle?
this has a y intercept of +2
the line goes up 1 to the right 2 so m = 1/2
the equation of a line in slope intercept form is
y = mx+b
y = 1/2 x + 2
Hey there!
Firstly, you need combine your like terms
stays the SAME 
- Combine the negative and the plus and make a negative symbol
Good luck on your assignment and enjoy your day!

Answer:
It'll take approximately 9.1 minutes
Step-by-step explanation:
The decay of this element can be modeled by the following expression:
m(t) = 540*(1 - 0.179)^t
Where m is the mass of the element in a given minute t. This expression comes from a compounded interest formula, with negative rate, since they will work in the same manner. Therefore to find how long until it reaches 90 g, we need to make m = 90 and solve for t.
90 = 540*(0.821)^t
(0.821)^t = 90 / 540
(0.821)^t = 1/6
ln(0.821^t) = ln(1/6)
t*ln(0.821) = ln(1) - ln(6)
t*ln(0.821) = - ln(6)
t = -ln(6)/ln(0.821) = 9.08452
It'll take approximately 9.1 minutes
