Answer:
A. 1/2
Step-by-step explanation:
The original figure has a side of 4 and the reduced figure has a side of 2
4:2
What do we multiply to get from 4 to 2
4x =2
Divide each side by 4
4x/4 = 2/4
x = 1/2
The scale factor is 1/2
Answer:
Step-by-step explanation:
Answer:
-x + 2y + 1 > 0
Step-by-step explanation:
Let's find the equation of the dashed line first. From the graph, we can see that it has a slope of 1/2 and a y-intercept of -1/2 so using slope-intercept form, the equation of the line is y = 1/2x - 1/2. Since the line is dashed and not solid, we know that we will use either < or > instead of ≤ or ≥, and because we can see that the shaded region is above the dashed line, we know that the linear equation is y > 1/2x - 1/2. However, we want the answer to be in the form ax + by + c > 0 where a, b, and c are integers so therefore:
y > 1/2x - 1/2
= 2y > x - 1
= -x + 2y + 1 > 0
