All you have to do is place an open circle at X = 2 and draw an arrow pointing to the left of the number 2. Since this represents all values less than 2, and not including 2, are possible solutions to the following inequality.
Rick has 1 1/3, or 4/3, pounds of sugar.
He needs to pour 1/4 of this amount into the bowl.
4/3 * 1/4 Multiply the numerators and the denominators
(4*1) / (3*4) = 4/12 Simplify, 4/12 can be simplified to 1/3.
He poured 1/3 pound of sugar.
Now, for flour, we need to find 1/4 of 2/3, using the same process:
(2/3) * (1/4) = (2*1) / (3*4) = 2/12 = 1/6
He poured 1/6 pound of flour
Y=90x+2,000
90 is the rate of change because the hot air balloon descends 90 feet per minute.
And 2,000 is the starting point because the hot air balloon started the descent at 2,000 feet.
