Answer:
sometimes correlated
Step-by-step explanation:
X+2x+5x=180
8x=180
4x=90
x=90/4
x=22,5
the angles are 22,5, 45, 112,5
x+2x+3x=180
6x=180
x=180:6
x=30
the angles are 30,60, 90
Are you sure the ex is correct???
Answer:
√5
Step-by-step explanation:
√(x2 - x1)² + (y2 - y1)²
√[-2 - (-1)]² + [0 - (-2)]²
√(-1)² + (2)²
√1 + 4
√5
Answer:
b
Step-by-step explanation:
The one missing is the fourth choice.
As you can see, the x axis stands for the weight, and the y axis the total cost.
You can see that the point, (1, 4) definitely exists.
So basically it would be 1 pound of cheese for four dollars, since x is weight and y is total cost.
You can see the fourth choice states that it's four dollars for one pound of cheese.
Hope this helped :)
