2 3/8 - 1 7/8
Change to improper fractions
19/8 - 15/8 = 4/8 = 1/2
Answer:
Rotation
Step-by-step explanation:
A transformation of a triangle can be either dilation or reflection or rotation or a translation.
Dilation happens when a symmetric figure is formed with scale factor other than 1. But here both triangles have same side length. Hence no dilation
Reflection happens when it is reflected over a line as we see in a mirror. But here the two triangles are not looking as images on a line. Hence no reflection
Rotation is keeping the same shape but rotating through a certain angle. Here DEF is rotated without disturbing its shape or size through a certain angle. Hence rotation is right
Translation is not right because there is no vertical or horizontal shift to get new triangle.
So the slope is (y2-y1)/(x2-x1)
(8-4)/(2-1)=
4/1 =
4
Aka. For every 1 week, the number of pictures taken increases by 4.
So it is 4 * w
Check:
4*w = total number of pictures
4*1 = 4
4*2 = 8
4*3 = 12
4*4 = 16
All match the table.
Answer:
x=130, x=-77.5, x=1/3
Step-by-step explanation:
1st equation:
1/5x + 24 = 50
1/5x = 26
x = 26(5)
x = 130
2nd equation:
0.4x + 18=-13
0.4x = -31
x=-77.5
3rd equation:
3x - 5/6 = 1/6
3x = 1
x=1/3
