Answer:
B. Point X
Step-by-step explanation:
Perpendicular Lines meet at a 90° angle.
Answer:
And using the same formula we can find the number of decible for the Braylee's music:
And since we want to find how many times louder is Braylee’s music than Jessica’s we can find the following relationship:
So then we can conclude that the Braylee's music is 3 times louder then the Jessica's sound. And the best option would be:
3 times louder
Step-by-step explanation:
For this case we know that the loudness measured in decibels is given by this formula:
Where 
. Using this formula we can find the decibels for the sound for Jessica:
And using the same formula we can find the number of decible for the Braylee's music:
And since we want to find how many times louder is Braylee’s music than Jessica’s we can find the following relationship:
So then we can conclude that the Braylee's music is 3 times louder then the Jessica's sound. And the best option would be:
3 times louder
Answer: The answer is g(x)=f(x+k), therefore it’s k=gx/f.
Step-by-step explanation: You’ll need to isolate the variable by dividing each side by the factors that don't contain the variable.
Answer:
using pythagorean theorem
Hypotenuse ²=Adjacent ²+ Opposite ²
Hypotenuse ²=5.6²+7.2²
Hypotenuse ²=83.2
Hypotenuse=√83.2
Hypotenuse=9.12m
The equations give you information as to where to plot points.
For y = -x + 1, you know the slope is -1, and the line intersects the y-axis at (0, 1). The y-axis is the vertical line; to plot (0, 1), find 1 on the vertical line and mark it. Now, the slope is -1; that means the line will slope downwards. To plot more points, count 1 unit down from (0, 1) and 1 unit to the right. You should end up at (1, 0).Connect those and you have a line.
For y = -2x + 4, the slope is -2 (so it will also slope downwards), and the y-intercept is 4. Find (0, 4) and plot it. The -2 tells you to count 2 units down (instead of 1 like we did for the last equation) and 1 over. That is the second line.
I hope this helps.
