Answer:

3) 5

5) 1

Step-by-step explanation:

substitute the value of 9 for each 'x' in the expression

3) h(9) = 2/3(9) - 1

= 18/3 - 1

= 6-1 or 5

substitute the value of 5 for each 'x' in the expression

5) f(5) = -5² + 6(5) - 4

= -25 + 30 - 4

= 5-4 or 1

Positive numbers are located to the right of zero on the number line. True False

Trava [24]

$\text {Hi!}$

$\text {The Answer to this Problem Is:}$

$\fbox {True!}$

$\text {When we look at a number line with positive and negative numbers we see}$ $\text {that positives are to the right and negatives are to the left.}$

$\text {As you can see the number line on the image that all}$ $\text {the negative numbers are to the left and positive numbers are to the right.}$

$\text {\underline {Remember}}$

$\text {Positive to the Right.}$

$\text {Negative to the Left.}$

$\text {Best of Luck!}$

Solve by completing the square.

enot [183]

Answer:

x^2 -8x -5 = -3

x^2 -8x -2 = 0

We complete the square by:

1) Moving the "non X" term to the right:

x^2 -8x = 2

2) Dividing the equation by the coefficient of X²

The coefficient of x is 1 so we don't do anything

3) Now here's the "completing the square" stage in which we:

• take the coefficient of X

that is -8

• divide it by 2

-8 ÷ 2 = -4

• square that number

-4*-4 = 16

• then add it to both sides of the equation.

x^2 -8x +16 = 2 +16

That becomes

(x -4)^2 = 18

we take the square root of both sides:

(x -4) = sqr root (18)

x1 = sqr root (18) +4

AND

(x+4) = sqr root (18) -4

x1 = sqr root (18) +4 = 4.2426406871 + 4 = 8.2426406871

x2 = sqr root (18) -4 = = 4.2426406871 - 4 = .2426406871
