Answer:
x=5, y=-9. (5, -9).
Step-by-step explanation:
y=-3x+6
y=-x-4
--------------
-3x+6=-x-4
-3x-(-x)=-4-6
-3x+x=-10
-2x=-10
2x=10
x=10/2
x=5
y=-5-4=-9
If I’m right it would be 9 just did in head so I’m not 100% sure
All this is asking you is to find how much you need to save per month (limit of 5) in order to make your goal of $1200.
To solve this, simply divide 1200 by 5, which is the months, and you get $240, which is how much you have to save per month in 5 moths to reach your exact goal of $1200. If anything is confusing please ask :)
Answer:
120 + 20π
Step-by-step explanation:
Find the image of the question attached.
For the square;
Perimeter of a square = 4L
L is the side length of the square
From the diagram, L = 10
Perimeter of a square = 4(10) = 40
Perimeter of 3 squares = 3(40) = 120
For the semicircles:
Perimeter of a semicircle = 2πr/2 = πr
From the diagram;
L = radius of the semicircle = 10
Perimeter of a semicircle = π(10)
Perimeter of a semicircle = 10π
Perimeter of the two semicircles = 2(10π) = 20π
perimeter of the shape = perimeter of 3squares + 2 semicircles
perimeter of the shape = 120 + 20π
