Here you would factor out a 1.7 because that is the coefficient in front of the j. When you factor, you are essentially dividing each term by the value you are factoring out
1.7j/1.7=j
-3.4/1.7=-2
So the final answer is 1/7(j-2)

Answer:
EF, where E is at (1, 9) and F is at (2, 5)
Step-by-step explanation:
Slope = rise/run or y/x. In a coordinate, a point on a graph is represented as (x,y). When the slope is -4 (or -4/1), this means the y value will decrease (as it is negative) by 4 units, while the x value increases (as it is positive) by 1 unit. The line EF demonstrates the values (1, 9) and (2, 5). The difference between them is (1, -4) in (x, y) form.
Answer:
you need to multiply the numbers
Step-by-step explanation:
1/5 ×2/5= 2/25
Answer:
A.) Extending the line of multiple of scale factor r on two corresponding vertex
B.) Scale factor r = 2.5
C.) A'B'/AB = 5/2
Step-by-step explanation:
A.) To find the centre O, take a corresponding vertex of the two shapes. Draw a line passing through the the vertex and extending beyond the initial one. The length of the line must be multiplied by the scale factor r
The center of a dilation is a fixed point in the plane in which all points are expanded or contracted.
B.) If AB=6 mm and A'B'= 15mm,
The scale factor r = 15/6 = 5/2 = 2.5
C.) A'B'/AB = 5/2
