Answer:

$-\frac{11}{9}$ , OR $-1\frac{2}{9}$ , OR -1.2

Step-by-step explanation:

$-\frac{8}{9}+\frac{1}{5}+(-\frac{8}{15})$ When there is a (+) in front of an expression in parentheses, the expression remains the same

$-\frac{8}{9}+\frac{1}{5}-\frac{8}{15}$ Calculate the sum or difference

Rewrite the function by completing the square. f(x)= x^{2} -9 x +14f(x)=x 2 −9x+14

Bess [88]

Answer:

$f(x)=(x-4.5)^{2}-6.25$ or $f(x)=(1/4)(2x-9)^{2}-6.25$

Step-by-step explanation:

we have

$f(x)=x^{2}-9x+14$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$f(x)-14=x^{2}-9x$

Complete the square. Remember to balance the equation by adding the same constants to each side

$f(x)-14+4.5^{2}=x^{2}-9x+4.5^{2}$

$f(x)+6.25=x^{2}-9x+4.5^{2}$

Rewrite as perfect squares

$f(x)+6.25=(x-4.5)^{2}$

$f(x)=(x-4.5)^{2}-6.25$

$f(x)=(1/4)(2x-9)^{2}-6.25$

The sum of two numbers is six, and the difference is 10. Find the numbers.

pashok25 [27]

First no. = x
Second no. = y

Equation Formation
x + y = 6..........equation(i)
x - y = 10...........equation (ii)

x = 6 - y
6 - y - y = 10
6 - 2 y = 10
-2 y = 10 -6
-2 y = 4
y = -2

x = 6 + 2
x = 8

Answer = 8 , -2
