1. Simplify the inequality 
2. Separate terms with x and without x in different sides:
3. Add similar terms:
4. Divide by 21.42:
Answer: correct choice is C.
Answer:
the y intercept are 0,0 the x intercepts are -8 '3
Step-by-step explanation:
remember solpe equal rise over run an m = x2 - x1
over
y2 - y1
Ratio of shadow to object's size = 2/7
Then, size of tree would be: 7/2 * 28 = 7 * 14 = 98 feet
So, your final answer is 98 feet

Doubling the side-lengths will multiply the area by four.
Proof:
Let the side-lengths of the rectangle by x and y. Clearly, the area will be x*y=xy. The new rectangle will have side-lengths 2x and 2y, and thus area 2x*2y=4xy. 4xy/xy=4 - hence, the new rectangle has four times the area of the old one.
