Answer:
16 and 19
Step-by-step explanation:
16 + 19 = 35
16 x 5 = 80
19 x 4 =76
80 is four less than 76 so therefore the answers are 16 and 19.
Answer:
top one is 0.6 bottom one is 0.1
D'(p) = -8p + 160
<span>-8p + 160 = 0 </span>
<span>-8p = -160 </span>
<span>p = 20 </span>
<span>~~~ </span>
<span>B) Number of drills sold when p = 20 is </span>
<span>D(20) = [ -4(20)^2 + 160(20) - 270 ] = 1,130 drills </span>
I think this is right, i tried.
(-2, -9)
Simply plug -2 into the equation.
1/3(12+x) = -8 (6-x)
Distribute the 1/3 and the -8 through their parentheses
4 + 1/3x = -48 + 8x
subtract 4 from each side
1/3x = -52 + 8x
subtract 8x from each side
1/3x - 8x = -52
combine like terms
1/3x - 24/3x = -52
-23/3x = -52
divide each side by -23/3 (multiply the reciprocal of the divisor)
x = -52 × -3/23
x = 156/23
x = 6 18/23 or 6.78
