MATH HELPERS PLEASE HELP!!!!
The solution set for all real numbers x such that 2x + 3 < 19 and 2x − 3 ≤ -7 is( , }

Note: If needed, type “-infinity” for -∞ and “infinity” for ∞.

Respuesta :

2x + 3 < 19
2x < 16
x < 8 (inequality 1)

2x - 3 ≤ -7
2x ≤ -4
x ≤ -2

Since both inequalities have a less than sign, the domain will go down to negative infinity. Since they have a common solution from x ≤ -2, the interval notation becomes (- infinity, -2]

Answer:

the last one (D) since the 3 graphs won't show.
