since brians shadow is 2/3rds his height
4 / 6 is 2 /3
20 / 30 is 2 / 3 too so flag pole must be 30 feet tall
-4x+7x-14
3x-14>-18
3x>-4
X>-4/3
Answer:
-2 <em>1/3</em>
Step-by-step explanation:
((4 * 3) - (-2) /(-2*3)
(12 + 2 ) / (-2 * 3)
14 / -6
-2 <em>1/3</em>
Answer:
1/2
Step-by-step explanation:
(0,3.75)(15,0)
slope(m) = (0 - 3.75) / (15 - 0) = -3.75/15 = - 0.25 or -1/4
y = mx + b
slope(m) = -1/4
(15,0)...x = 15 and y = 0
now we sub
0 = -1/4(15) + b
0 = -15/4 + b
15/4 = b
y = -1/4x + 15/4
1/4x + y = 15/4....multiply by 4
x + 4y = 15.....and since it is a solid line, it contains an equal sign...and since it is shaded above the line, it is greater.
so ur inequality is : x + 4y > = 15 (thats greater then or equal)
