Answer:

Step-by-step explanation:

Each game costs 2 dollars, so that total spent on games will be 2 * x. We have to add the one time payment of $3, so this will be (2 * x) + 3. Finally, she spends a total of $17, so the final equation will be (2 * x) + 3 = 17.

The value of the expression 6 +5. (8 + 2)² is 506 after solving with BODMAS rule.

It is defined as the combination of constants and variables with mathematical operators.

We have an epression:

= 6 +5. (8 + 2)²

We can solve the above expression by BODMAS:

= 6 + 5(10)²

= 6 + 5(100)

= 6 + 500

= 506

Thus, the value of the expression 6 +5. (8 + 2)² is 506 after solving with BODMAS rule.

The value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory option (A) is correct.

Last in, first-out (LIFO) is an inventory valuation approach based on the principle that the first asset sold is the most recent asset received.

We have data shown in the table:

Total number of T-shirts = 200+300+400+300 = 1200

As there are only 400 T-shirts left it means,

So (1200-400)800 T-shirts sold out according to LIFO last month T-shirt sold out.

200 T-shirts left in the June stock

Out of 300, there are 200 T-shirts left in the month of July.

Cost for 200 T-shirts = 200×8 = $1600

Cost for 200 T-shirts = 200×10 = $2000

Total cost = 1600+2000

= $3600

Thus, the value of its current stock is $3600 if the graphic design works use LIFO, and it has 400 T-shirts left in its inventory.

Answer:

-48/15, simplified to -16/5

Step-by-step explanation:

The reciprocal of -3/8 is -8/3. So the equation will be 6/5 x -8/3. Multiply numerators then multiply denominators to get -48/15. This can simplify to -16/5 by dividing both by 3.

Answer:

Step-by-step explanation:

hello :

6/5 by the reciprocal of (-3/8)  means : ( 6/5 )(-8/3) = - 48/15 = -16/5

Answer:

y ≤ 66.28 -> -∞

Step-by-step explanation:

y = a (x-h)² + k     ... (h,k): vertex

y = - 32x² + 90x + 3

  = -32 (x² - (90/32)x + (90/64)²) + (3 + (32)*(90/64)²)

  = -32 (x² - 2*(90/64)x + (90/64)²) + (3+63.28)   ... 90/64=1.41

  = -32 (x - 1.41)² + 66.28

h = 1.41

k = 66.28 .... extremum of y value

y ≤ 66.28 (y is real number)
