4b² + 8b + 3 = 0

4b² + 2b + 6b + 3 = 0

2b(2b + 1) + 3(2b + 1) = 0

(2b + 3)(2b + 1) = 0

b = -1/2 or b = -3/2

So I need help pls show ur work
Ad libitum [116K]

Answer:

x = – ⅓

Step-by-step explanation:

The solution to the expression can be obtained as follow:

–3.1x + 7 – 7.4x = 1.5x – 6(x – 3/2)

Clear bracket

–3.1x + 7 – 7.4x = 1.5x – 6x + 9

–3.1x – 7.4x + 7 = –4.5x + 9

–10.5x + 7 = –4.5x + 9

Collect like terms

–10.5x + 4.5x = 9 – 7

–6x = 2

Divide both side by –6

x = 2 / –6

x = – ⅓

Thus, the solution to the equation is –⅓

What is the inverse of the function? f(x) = 2x - 10?
gulaghasi [49]

Answer:

Step-by-step explanation:

Let f(x)=y

y=2x-10

Switch x and y,

x=2y-10

x+10=2y

(x/2)+5=y

So f^{-1}(x)=\frac{x}{2}+5
