Mathematics
1 answer:
valina [46]3 years ago
8 0

Answer:

The solution set for the inequality is the interval (-4, 5)

Step-by-step explanation:

-8 < 8 + 4x < 28

Subtracting 8:

-8 -8 < 8 + 4x - 8 < 28 - 8

-16 < 4x < 20

Dividing by 4:

-16/4 < 4x/4 < 20/4

-4 < x < 5

x ∈ (-4, 5)

Evaluate the following expressions for a = -3,b=2,c=5
Ksju [112]

Hey!

----------------------------------------------------------------------

We know that (a = -3), (b = 2), (c = 5), and (d = -4).

----------------------------------------------------------------------

Solution #1:

=\frac{a-4b}{3c+2d}

=\frac{(-3) - 4(2)}{3(5) + 2(-4)}

=\frac{(-3) - 8}{15 +( -8)}

=\frac{-11}{7}

≈ 1.57

----------------------------------------------------------------------

Solution #2:

= a - 4b / 3c + 2d

= (-3) - 4(2) / 3(5) + 2(-4)

= (-3) - 8 / 15 + (-8)

= (-3) - 0.53 + (-8)

= (-3.53) + (-8)

= -11.53

----------------------------------------------------------------------

Solution #1 Answer: 1.57

Solution #2 Answer: -11.53

----------------------------------------------------------------------

Hope This Helped. Good Luck! Brainly is here to help :)
