Answer:
slope = 1/2
Step-by-step explanation:
slope = y2-y1 / x2-x1
1 - -2 / 4 - -2 = 3/6 = 1/2
or think of it this way. for every 1 step up you take 2 steps to the right to stay on the line. 1/2

Find the solution set
From the question, we have that;
4½n - 9½ > 62.5
Convert all numbers to decimal
4.5n - 9.5 > 62.5
Add 9.5 to both sides
4.5n - 9.5 + 9.5 > 62.5 + 9.5
4.5n > 72
Multiply both sides by 2
2(4.5n) > 72 * 2
9n > 144
Multiply both sides by ⅑
⅑ * 9n > 144 * ⅑
n > 16
This implies that n ranges to infinity from positive 16;
Hence, the correct answer is {16, +infinity}

To find AC, (2^2)+(3^2)=4+9=13
AC=the square root of 13
Answer: 640
Step-by-step explanation:
The scale factor is 20/5=4, so the ratio of the areas is the square of this, or 16.
Thus, the area of ABCD is 40(16)=640.
Point A' is at (-2,-2)
Point D' is at (-2,4)
Just multiply each coordinate by 2
