6.
6 tons= 12,000 pounds
12,000-7,860= 4,140
so the answer is 4,140 pounds
7. 3 cups= 24 fluid ounces
40 - 24 = 16 fluid ounces
16 fluid ounces= 1 pint
so the answer is 1 pint left in the pitcher
8. 2.5 x 18= 45 feet
45 feet= 15 yards
so the answer is 15 yards
First you need to solve for x by subtracting 9 from both sides (-3x less than/equal to 6), then dividing the inequality by -3, which would also flip the sign, so to speak. now you would have x is greater than/ equal to -2. now you would draw a circle above -2, fill it in since it is equal to, and draw the arrow going toward 0 (I think)
She must start out going 8 miles per hour until the time elapsed is 1 hour at which time she drops 1.5 miles per hour. The same happens again in the second hour and the third.
The graph must have hours on the x axis and speed on the y axis.
The starting point is (0,8)
The graph must be
y = 8 - 1.5x
You need three points.
x y
0 8
1 6.5
2 5
Basically the remainder theorem links the remainder of division by a binomial with the value of a function at a point while the factor theorem links the factors of polynomial to its zeros
