Answer:
For f(x) = √(2·x + 2) - √(x + 18), at f(x) = -1 the possible x-values includes;
-0.757, -17.5
Step-by-step explanation:
Given that the function is f(x) = √(2·x + 2) - √(x + 18)
The value of 'x' when f(x) = -1, is given as follows;
-1 = √(2·x + 2) - √(x + 18)
-1² = (√(2·x + 2) - √(x + 18))² = 3·x + 20 - 2·√(2·x + 2)×√(x + 18)
1 = 3·x + 20 - 2·√(2·x + 2)×√(x + 18)
2·√(2·x + 2)×√(x + 18) = 3·x + 20 - 1 = 3·x + 19
2·x² + 38·x + 36 = (3·x + 19)/2
2·x² + 38·x + 36 - (3·x + 19)/2 = 0
4·x² + 73·x + 53 = 0
From which we get;
x = (-73 ± √(73² - 4 × 4 × 53))/(2 × 4)
x ≈ -0.757, and x ≈ -17.5
The initial value equation is 
<h3>How to solve the initial value?</h3>
The equation is given as:
Where
Y(0) = 1
Subtract 2y from both sides in the equation
Rewrite as:
Integrate both sides of the equation
Multiply through by -2
Take the exponent of both sides
Next, we solve for C under the initial condition Y(0) = 1.
This gives
Evaluate
-2 + 3 = C
Solve for C
C = 1
Substitute C = 1 in
Next, we solve for y
Hence, the initial value equation is

Answer:idk how to do this im in 7th grade
6.4 ounces.
You can get this by first converting to ounces which is a smaller value. Then you can divide by 10.
