Answer:

X=(-3)

Step-by-step explanation:

1.Subtract 8 from both sides of the equation.-(x+0)=5-8-the 0 is there because the 8 on the left side is canceled out.

2.5-8 is all you have to look at.-when you look at this you know that it will be negative because 8 is on the right of the minus sign and it is greater than 5.

3.Use a calculator or you fingers to find answer.-(4,3,2,1,0,-1,-2,-3)

HOPE THIS HELPS!!!

Find the slope of the line through the points (4, 4) and (-1, 5).

We write pattern linear function
f(x) = ax + b

Both points must be in one straight line so they can be used to lay the system of equations .
Points A=(4,4), B = (-1,5)
x y x y

 $\left \{ {{f(x)=ax + b (Point A)} \atop {f(x) = ax +b (PointB)}} \right. \\ \\ \left \{ {{4 =a*4 + b} \atop {5=a*(-1)+b}} \right. \\ \\ \left \{ {{b= 4 -4a} \atop {5 = -a + (4 - 4a)}} \right. \\ \\ \left \{ {{b = 4 - 4a} \atop {5 - 4 = - 5a }} \right. \\ \\ \left \{ {{b = 4 - 4a} \atop {a = - \frac{1}{5} }} \right. \\ \\ \left \{ {{ b = 4 - 4*(- \frac{1}{5} )= 4 + \frac{4}{5} = 4,8} \atop {a = - \frac{1}{5} }} \right.$

We insert the calculated a and b in the equation f(x) = ax + b

 $y = - \frac{1}{5} x + 4,8$

Since a> 0, the function is decreasing

Sam said the square root of a rational number must be a rational number. Jenna disagreed. She said that it is possible that the

ratelena [41]

Jenna is correct because the square root of a rational number can still be irrational.

Take for example the square root of 2. It is an irrational number than goes 1.41421...

If you multiply just the first however many digits of the result by itself, you will never end up with a perfect 2, because the square root is irrational.
