4x²-5=3x+4
4x²-3x-9=0

x=(3±√((-3)²-4*4*-9))/2*4

x=3±√(9+144) /8

x=(3±√153) /8

x=⅜±√153/8

Answer:

3rd option.

Step-by-step explanation:

$\frac{2|k|}{5}$ = 4

move 5 to the other side of the equation.

2|k| = 5(4)

2|k| = 20

move 2 to the other side of the equation.

|k| = $\frac{20}{2}$

k = 10

Suppose the average temperature for a 4‐day period in Chicago, Illinois, is ‐8Ԭ. After the next day, the 5‐day average is ‐9Ԭ. W

exis [7]

Answer:

-13

Step-by-step explanation:

Given that:

Average temperature for a period of 4 days = - 8

Average temperature for a 5 day period = - 9

Temperature on the 5th day:

(total temp for the 4 days + 5th day temperature) / 5 = - 9

Let 5th day temperature = x

Total temperature for the 4 days = 4 * - 8 = - 32

(-32 + x) / 5 = - 9

-32 + x = - 45

x = - 45 + 32

x = - 13

6(7x-4y)-5 it says to use distributive property to answer

Alexeev081 [22]

Answer:

42x-24y-5

Step-by-step explanation:

We can start by using the distributive property.

This will help us rewrite the expression, since the terms in the parentheses can't be combined.

I'll attach an image to better explain this.

When using it, we'll get:

6*7x+6*-4y-5

Simplify.

42x-24y-5

This is our final answer since there are no like terms that can be combined.
