From the question, we understand that one shrub must be at both ends.
Taking the first as a point of reference, we're left with:
Substitute 10 for n and d for distance
Hence:

Answer:
See below.
Step-by-step explanation:
x^2 = y + 16
4y - 1 = 7x
are the 2 equations. (answer)
From the second equation
4y = 7x + 1
y = 7/4 x + 1/4
Substituting in the first equation:
7/4x + 1/4 + 16 = x^2
x^2 - 7/4 x - 16 - 1/4 = 0
x^2 - 7/4 x - 16 1/4 = 0
Multiplying though by 4
4x^2 - 7x - 65 = 0
Using the ac method to solve this 4 * -65 = -260 and we need factors of this to add up to -7. -20 and 13 look good so we write:
4x^2 - 20x + 13x - 65 = 0
Fatcor by grouping:
4x(x - 5) + 13(x - 5) = 0
(4x + 13)(x - 5) = 0
So the the roots are 5, -3.25
To find the values of y we substitute these values of x into the second equation:
x = 5: 4y - 1 = 7*542y = 36
y = 9.
x = -3.25:
4y - 1 = 7*-3.25
4y = (7 * -3.25) + 1
y = -5.44.
So the solutions are (5, 9) and (-3.25, -5.44) (Answer)

Answer:
C. (f - g)(x) = 3ˣ - 2x + 14
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
- Function Notation
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3ˣ + 10
g(x) = 2x - 4
(f - g)(x) is f(x) - g(x)
<u>Step 2: Find (f - g)(x)</u>
- Substitute: (f - g)(x) = 3ˣ + 10 - (2x - 4)
- Distribute -1: (f - g)(x) = 3ˣ + 10 - 2x + 4
- Combine like terms: (f - g)(x) = 3ˣ - 2x + 14
