Answer:

s\in (-\infty,1)

Step-by-step explanation:

Solve the inequality -2(s - 7) > 4s + 8

Use distributive property:

-2s+14>4s+8

Subtract 4s:

-2s+14-4s>4s+8-4s\\ \\-6s+14>8

Subtract 14:

-6s+14-14>8-14\\ \\-6s>-6

Divide by -6 (do not forget to change sign, because division by negative number changes the sign):

s

amid [387]

From 2 to 101 , the perfect square numbers are ,

  • 4 , 9 , 16 , 25 , 36 , 49 , 64 , 81 , 100 .

Total number of possible outcomes = 100.

Total number of favourable outcomes = 9 .

Hence ,

→ <u>P ( of getting perfect square ) = 9/10</u><u>0</u>

Find the solution to the system of equations. You can use the interactive graph below to find the solution. y=-4x-3 y=-2x+1 x= y
Mama L [17]

Answer:

(-2, 5)

Step-by-step explanation:

I will assume that your system is

y = -4x - 3

y = -2x + 1

Multiplying the second equation by -2 results in

 y = -4x - 3

-2y = 4x - 2

combining these two equations eliminates x temporarily:

-y = -5, so that y must be 5.

Substituting 5 for y in the second equation, we get:

5 = -2x + 1, or

4 = -2x, which results in x = -2

and so the solution is (-2, 5)
