Can’t really answer without a picture
Hi.
I'm going to tell you the process, since I don't have a calculator on me. Don't wanna risk it, lol.
We can break this shake into 2 parts: a rectangle, and a triangle.
To separate them, just calculate the area of the rectangle with 4 km & 3.5 km
Since the triangle's area is half that of the rectangle, all we need to do is divide the area of the rectangle by 2 to get the area of the triangle (it's confusing when in words, eh?)
Once you find the area of both, add them together.
This should get you the area of the shape.
I hope this helped. Once again, please let me know if there are mistakes.
Answer:
Only on the surface
Step-by-step explanation:
The problem is that you can't get out of the water without passing through the surface.
Answer:
Hence x = -1 and y = 18
<em></em>
Step-by-step explanation:
Given the system of equations
y + 8x = 10... 1
2y - 4x = 40 ... 2
From 1; y = 10-8x
Substitute into 2;
2(10-8x) - 4x = 40
20 - 16x - 4x = 40
20 - 20x = 40
-20x = 40 - 20
-20x = 20
x = -1
Recall that y = 10-8x
y = 10 - 8(-1)
y = 10 + 8
y = 18
Hence x = -1 and y = 18

Answer: C. (2, -4)
Step-by-step explanation:
Take into consideration that y is less than or equal to -2. The only option in which the y value is less than or equal to -2 is option C., thus C would correctly solve the system of inequalities.
