The cost , in dollars, for 3 pounds of oranges is 1.8
Solution:
Given that Monica paid 3.20 for 2 pounds of apples and 2 pounds of oranges
Sarah paid 4.40 for 2 pounds of apples and 4 pounds of oranges.
Let the cost of orange per pound = x
Let the cost of apple per pound = y
Therefore, we can frame an equation as follows for Monica and Sarah:
In Monica’s case:
2x + 2y = 3.20
Hence x + y = 1.6 ---- eqn 1
In Sarah’s case:
4x + 2y = 4.40
Hence 2x + y = 2.2
y = 2.2 -2x – eqn 2
Substitute eqn 2 in eqn 1 we get,
x + 2.2 -2x = 1.6
-x = 1.6-2.2 = -0.6
x = 0.6
Substituting the value of “x” in eqn 2 we get the value of “y” as 1
Thus the cost of orange per pound is 0.6
Therefore, cost of 3 pounds of oranges = 3 × 0.6 = 1.8
Answer:
Coordinates of the image are (4 , -1)
Explanation:
The rule for 180° rotation counterclockwise is:
(x , y) ⇒ (-x , -y)
This means that to get the coordinates of a point rotated 180° counterclockwise, all you have to do is flip the signs of both the x and the y
Now, we are given the point (-4 , 1)
Applying the above rule:
Hope this helps :)
A 180 degrees counterclockwise rotation around the origin (0,0) would flip a point (x,y) to its opposite (-x,-y). Therefore, if you rotate the point (-4,1) 180 degrees counterclockwise, the new coordinates of the point would be (4, -1).
In Mathematics, specifically in Geometry, when we conduct a 180 degrees counterclockwise rotation around the origin (0,0), every point on the plane rotates by 180 degrees in the counterclockwise direction.
For a point (x,y), a 180-degrees rotation would result in the point ending up at (-x,-y).
Therefore, if you rotate the point (-4,1) 180 degrees counterclockwise around the origin, the new coordinates of the point would be (4, -1).
