Answer: Choice A
The two characteristics here are:
- The boundary line is a dashed line. This visually indicates to the reader "points on the boundary do NOT count as solutions". Think of the boundary as an electric fence you cannot touch, but can get closer and closer to. We aren't including boundary points directly because of the lack of "or equal to".
- The shading is above the boundary, due to the "greater than" sign. This only works if we have y isolated.
The graph of choice B is since we have a solid line and shading below the solid line. This time points on the boundary are part of the solution set.
Answer:
x = -2
Step-by-step explanation:
6 more then the product of 5 and a number x is -4
" the product " means multiply
5x + 6 = -4
5x = -4 - 6
5x = -10
x = -10/5
x = -2 <===
Answer:
1140 ways.
Step-by-step explanation:
The applicable formula is: (n +r - 1)C(r-1), where n is the number of identical items (the candies), and r is the possible number of recipients (the kids).
The 17 identical candies, can be distributed among the 4 children in :
=(17 + 4 - 1)C(4–1) = 20C3 ways.
= 20!/((20–3)!*3!) ways.
= 20*19*18*17!/(17!*(3*2*1)) = 20*19*18/6 ways
= 20*19*3 ways.
=1140 ways.
The answer is 10/3=3 1/3
Unit fraction=1/3
Answer:
5.64
Step-by-step explanation:
To find the radius of a square, cut in half 4/2 = 2. Then square it 2x2 = 4. Then double it to get 8. Then find square root, 2.82. Then double again for full length of diagonal.
