In y = mx + b form, the slope will be in the m position and the y int will be in the b position

y = -2x + 2....slope = -2 and y int = 2
y = -2x - 3.....slope = -2 and y int = -3

when u have 2 lines that both have the same slope but different y intercepts, u have parallel lines with no solution because ur lines never intersect.

so ur answer is : no solutions or 0 solutions

Answer:

D) (2, 14)

Step-by-step explanation:

substitute each coordinates into the inequality:

(0, 0)

y > 5x

0 > 5*0

0 > 0

this is false, 0 = 0.

(3, 12)

y > 5x

12 > 5 * 3

12 > 15

this is false, 12 < 15

(-2, -10)

y > 5x

-10 > 5 * -2

-10 > -10

this is false, -10 = -10

(2, 14)

y > 5x

14 > 5 * 2

14 > 10

this is true, 14 > 10

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.
