Answer:
The slope of a line parallel to this line will be: -7/9
The slope of the perpendicular line will be:
![\frac{-1}{\frac{-7}{9}}=\frac{9}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7B%5Cfrac%7B-7%7D%7B9%7D%7D%3D%5Cfrac%7B9%7D%7B7%7D)
Step-by-step explanation:
We know the slope-intercept form
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Here,
Given the equation
![7x+9y=5](https://tex.z-dn.net/?f=7x%2B9y%3D5)
simplifying to write in the lope-intercept form
![y=-\frac{7}{9}x+\frac{5}{9}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B7%7D%7B9%7Dx%2B%5Cfrac%7B5%7D%7B9%7D)
Thus, the slope of the line is: -7/9
The slope of a line parallel to the line:
We have already determined that the slope of the line is: -7/9
- We know that the parallel lines have the same slope.
Thus, the slope of a line parallel to this line will be: -7/9
The slope of a line perpendicular to the line:
We have already determined that the slope of the line is: -7/9
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.
Thus, the slope of the perpendicular line will be:
![\frac{-1}{\frac{-7}{9}}=\frac{9}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B-1%7D%7B%5Cfrac%7B-7%7D%7B9%7D%7D%3D%5Cfrac%7B9%7D%7B7%7D)
Answer:
each side is 55.125cm
Step-by-step explanation:
you have to divide the area by 2
then do 441/2=220.5
then divide this by 4 because a square has 4 equal sides so 220.5/4=55.125
Answer:
D
Step-by-step explanation:
Neither the table and the graph is correct.
Answer:
A
Step-by-step explanation:
To find how long it takes for the object to hit the ground you need to set h(t)=0 after this you need to find the number that when plugged into t makes the equation equal to 0
