Steps:
1. Substitute the y in 4x + 10 with -5x-10
-5x-10= 4x + 10
2. Add 5x on both sides
-10= 9x + 10
3. Subtract 10 on both sides
-20= 9x
4. Divide by 9 on both sides
5. Your answer is
X= -20/9
Answer:
at least 123 feet
Step-by-step explanation:
Using the given formula, we have ...
A = bh
3800 = b(b/4) . . . . substituting the given information
15200 = b^2
b = √15200 ≈ 123
_____
The base of a parallelogram is not necessarily the longest side, regardless of height. Since the base is 123 feet, we can only say that the longest side is no shorter than 123 feet.
Answer:
21
Step-by-step explanation:
You have to find the square root.
We need to position the four points so they all are on the graph of an exponential function.
As an example of an exponential function, let's use the following function:
Now, to find where the points should be located, let's choose some values of x and calculate the corresponding values of y:
Therefore the points should be located at (-2, 1/4), (-1, 1/2), (0, 1), and (1, 2).
