The equation of the line is y = -11x + 232
<h3>How to determine the equation?</h3>
The given parameters are:
Slope (m)= -11
Point (x1, y1) = (31, -109)
The linear equation is then calculated as:
y = m(x - x1) + y1
This gives
y = -11(x - 31) - 109
Evaluate the product
y = -11x + 341 - 109
Evaluate the like terms
y = -11x + 232
Hence, the equation of the line is y = -11x + 232

Answer:
Around 1,500 pounds
Step-by-step explanation:
Because you said "estimate," I will be estimating this.
49% rounds up to 50%
3,025 rounds down to 3,000
50% of 3,000 is 1,500 pounds.
7x - 8 = 34
Solving:
7x = 34 + 8
7x = 42
x = 6
Hope this helps!
A half-life of the isotope is 15 days and at start its mass is 32 g.
A table:
t: m:
0 32 g
15 16 g
30 8 g
45 4 g
60 2 g
75 1 g
In the first column is used an arithmetic sequence ( a 1 = 0, d = 15 ).
In the second column is used a geometric sequence ( a 1 = 32, r = 1/2 )
