You don't have to look very far in either case. Both answers are "a".

1. Checking selection "a",
  265 =? 35 +20*7 = 35 +140 = 175
  a (7, 265) is NOT a solution

2. Checking selection "a",
  18 =? 5*4 -2 = 20 -2 = 18
  a (4, 18) IS a solution

The difference of two perfect cubes is 386. If the cube root of the smaller of the two numbers is 7, then the cube root of the l
choli [55]

Answer:

9

Step-by-step explanation:

Let the two perfect cubes be x and y where x > y.

According to the given conditions:

{x}^{3}  -  {y}^{3}  = 386...(1) \\ y = 7...(2) \\ plug \: y = 7 \: in \: equation \: (1) \\  {x}^{3}  -  {7}^{3}  = 386 \\ {x}^{3}  -  343 = 386 \\ {x}^{3}     = 343  +  386 \\ {x}^{3}     = 343  +  386 \\ {x}^{3}   = 729 \\ x =  \sqrt[3]{729}  \\ x = 9

Thus the cube root of the larger number is 9.

PLS HELP ME WITH THIS I NEED IT QUICK!!!!!!!!!!!
stepladder [879]

Answer:

Below in bold.

Step-by-step explanation:

-6x + 3y = -7

The x intercepts occur when y = 0, so

-6x + 3(o) = -7

x = -7/-6

x = 7/6

So the x-intercept =  (7/6, 0).

The y intercept:

-6(0)  + 3y = -7

y = -7/3.

So the y-intercept =  (0, -7/3.t).
