Answer:
I think it is C
Step-by-step explanation:
You can read it of the graph which is (1,3) or also calculate it with vectors:
calculate the vector CD:
(5-(-3),2-4)=(8,-2)
to calculate the midpoint you need half of the vector length:
(8,-2)/2=(4,-1)
add the vector to C:
(-3,4)+(4,-1)=(1,3)=midpoint of CD
so it's the third option
Answer:
The solution to the system of equations is:
The graph is attached below.
Step-by-step explanation:
Given the system of equations
Let us solve the system of equations using the elimination method
Arrange equation variables for elimination
Multiply y + 2x = 5 by 2: 2y + 4x = 10
subtracting the equations
solve 6x = 18 for x
Divide both sides by 6
simplify
For 2y - 2x = -8 plug in x = 3
Add 6 to both sides
Simplify
Divide both sides by 2
Simplify
Therefore, the solution to the system of equations is:
The graph is attached below.
To find the answer to this question, we simply add all the prices of the items together.
325+225+79=629
Then subtract 438 from 629.
629-438=191
He needs to save $191 to buy the items.
Hope this helps!
See the diagram in the attached figure
we know that the area of rectangular shaped playground is--> 80*100=8000 m²
the area of the pathway=[(100+2)*(80+2)]-[80*100]=8364-8000=364 m²
the answer is 364 m²
