The exercise is basiacally asking for the perimeter of the garden. The perimeter of a rectangle is twice the sum of its dimensions, so we have

Answer:
- f(-2) = 4
- f(1) = -5
- D: [-3, ∞)
- R: [-5, 11]
Step-by-step explanation:
You have marked the points on the graph corresponding to ...
f(-2) = 4
f(1) = -5
__
The domain is the horizontal extent, from x = -3 to +∞.
The range is the vertical extent, from y = -5 to +11 (inclusive).
Answer:
6 ft
Step-by-step explanation:
Since the distance between the bottom of the ladder and the wall forms a right angle that is across from the ladder, you can use the Pythagorean Theorem to solve for the value of 'x':
a² + b² = c², where 'a' and 'b' are the legs of the triangle and 'c' is the diagonal or hypotenuse.
Using 8 for 'a' and 10 for 'c':
8² + x² = 10²
64 + x² = 100
Subtract 64 from both sides:
64 - 64 + x² = 100 - 64 or x² = 36
Take the square root of both sides:
√x² = √36
x = 6 ft
Answer:
Step-by-step explanation:
-8-10,-12-14
-8 plus -12 is -20
-20 times 5 is -100
-14 times 8 is -112
-100 is 12 more than -112
A reflection is a mirror image. Placing the edge of a mirror on the x-axis will form a reflection in the x-axis. This can also be thought of as "folding" over the x-axis.
If the original (parent) function is <span>y = f (x)</span><span>, the <span>reflection over the x-axis </span>is function</span><span> -f (x)</span><span>.</span>
