–3(5y – 4) ≥ 17 Solve and graph on a number line thanks
likoan [24]

Answer:

y\leq 1.93

Step-by-step explanation:

  • To know the value that y takes according to the inequation -3(5y-4)\geq 17, we must do some algebra.
  • First of all, we divide both terms by (-3), wich would change the direction of the inequality, as follow: (5y-4)\leq\frac{17}{(-3)} (at this point you should remember that dividing or multiplying an inequation by anegative number changes the direction of the inequality)..
  • This means that (5y-4)\leq 5.67. Then,we just have to add both sides 4, which yields 5y\leq 5.67+4.
  • Then 5y\leq 9.67, which means that, if we divide both sides by 5, we obtain the value of y: y\leq 1.93 (in this case, the direction of inequality does not change because 5 is possitive).

I’m honestly confused on how to solve for k. please help.
stellarik [79]

Answer:

k=9

Step-by-step explanation:

slope =  \frac{y2 - y1 }{x2 - x1}  \\  \frac{ - 5}{2}  =  \frac{ - 11 - k}{6 - ( - 2)}  \\  -  ( \frac{5}{2} ) =  - ( \frac{11 + k}{8} ) \\  \frac{5}{2}  =  \frac{11 + k}{8}  \\ 5  \times 8 = 2(11 + k) \\ 40 = 22 + 2k \\ k =  \frac{40 - 22}{2}  \\ k = 9
