If square root m= 8, then m must equal ____. 4. 8. 16. 64

Whitepunk [10]

Answer:

Step-by-step explanation:

To find m, it has given you √x = 8. The opposite of a square root is squaring (exponentials). Simply just square 8 and you should get x = 64. You can check by square rooting 64, and you should get 8.

Maximize the objective function P = 2x + 1.5y for the feasible region shown. State the maximum value for P and the ordered pair

umka2103 [35]

Incomplete question. However, let's assume this are feasible regions to consider:

Points:

- (0, 100)

- (0, 125)

- (0, 325)

- (1, 200)

Answer:

Maximum value occurs at 325 at the point (0, 325)

Step-by-step explanation:

Remember, we substitute the points value for x, y in the objective function P = 2x + 1.5y.

- For point (0, 100): P= 2(0) + 1.5 (100) =150

- For point (0, 125): P= 2(0) + 1.5 (125) =187.5

For point (0, 325): P= 2(0) + 1.5 (325) = 487.5

For point (1, 200): P= 2(1) + 1.5 (200) = 302

Therefore, we could notice from the above solutions that at point (0,325) we attain the maximum value of P.

(2y+9)+(3d+5)=? *simplify your answer*

netineya [11]

Answer:

$2y + 3d +14\\2(y+7)+3d$

Step-by-step explanation:

We remove the bracket and rearrange the numbers to add them. Only similar variables can be added together.

$(2y+9)+(3d+5)\\2y+9+3d+5\\2y + 3d + 9 +5\\2y + 3d + 14\\2(y+7)+3d$
