Answer:
If the question is asking for a solution for both, then only point (0,2)
Point (0,2) is a solution to both equations
Point (5,3) is a solution to neither (meaning not any of the equations)
Point (-2, 16) is not a solution to the<u> first equation</u>, but is to the <u>second</u>
Point (-4, -9)<u> is a solution</u> to the first, but <u>not </u>to the second.
Step-by-step explanation:
Using the Property of substitution. 7x-4y=8
(0,-2)
7(0)-4(-2)=8
7(0)=0
-4(-2)=8
0+8=8
This solution is true.
(5,3)
7(5)-4(3)=8
7(5)=35
-4(3)=-12
35-12=23 (not 8)
This solution is not true.
(-2,16)
7(-2)-4(16)=8
-14-64=-78 (not 8)
This solution is not true.
(-4,-9)
7(-4)-4(-9)=8
-28+36=8
This solution is true
__________________________________________________________
Y=-9x-2
(0,-2)
-2=-9(0)-2
-9(0)=0-2=-2
-2=-2
This solution is true
(5,3)
3=-9(5)-2
-45-2=-47
3=-47
This solution is not true
(-2,16)
16=-9(-2)-2
16=18-2
16=16
This solution is true.
(-4,-9)
-9=-9(-4)-2
-9=36-2
-9=34
This solution is not true.
Answer: -2√5
Step-by-step explanation:
If the radius of the ball is 1 meter. Then the diameter of the ball will be 2 meters.
<h3>What is Geometry?</h3>
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The volume of a water walking ball (in cubic meters) is given below.
Then the diameter of the sphere will be
We know the volume of the sphere is given as
where r is the radius of the ball.
Then the radius of the ball will be
Then the diameter of the ball will be
d = 2r
d = 2 × 1
d = 2 m

You would divide 350m by 50m to get the number of inches between the two cities. 350/50= 7 inches. Hope this helped (I wasn't sure if this was what you were looking. I am sorry for the inconvenience).
