The answer is d.61. 66+7=73. 13+8=21. 52+9=61. 10+10=20
<span>17 x X = A, i think.</span>
0.06x+0.09 (1200-x)=96
Solve for x
X=400 at 6%
1200-400=800 at 9%
(-2,15)(9,-18)
slope = (-18 - 15) / (9 - (-2) = -33/11 = -3
There can be 2 answers to this question....
point slope form : y - y1 = m(x - x1)
(1) using points (-2,15)...
y - 15 = -3(x + 2) <== one possible answer
(2) using points (9,-18)
y + 18 = -3(x - 9) <== another possible answer
