Evaluate the expression for x = 8, y = 4: x + 10/y+5

Nesterboy [21]

Answer:

Solution,

X=8

y=4

Now,

 $\frac{x + 10}{y + 5} \\ = \frac{8 + 10}{4 + 5} \\ = \frac{18}{9} \\ = 2$ 

hope this helps...

Good luck on your assignment..

Which of the following are solutions to the equation below? x2 + 6x + 9 =6

svetoff [14.1K]

The correct answer would be 3 +/- $\sqrt{6}$

In order to solve for this you must first get the equation equal to 0.

x^2 + 6x + 9 - 6 ----> simplify like terms
x^2 + 6x + 3

Now knowing this we can use the coefficients of each one in descending order of power as a, b and c.

a = 1 (because it is the coefficient to x^2)
b = 6 (because it is the coefficient to x)
c = 3 (because it is the end number)

Now we can plug these values into the quadratic equation.

$\frac{-b +/- \sqrt{b^{2} - 4ac } }{2a}$

$\frac{-6 +/- \sqrt{6^{2} - 4(1)(3) } }{2(1)}$

3 +/- $\sqrt{6}$

And those would be your two answers.

What is the simplified form of the quantity of x plus 7, all over the quantity of 6 − the quantity of x plus 5, all over the qua

vlabodo [156]

For this case we must simplify the following expression:

$\frac {\frac {x + 7} {6- (x + 5)}} {x + 3}$
