Your answer is 160
2 times Negative 8 plus 5 times Negative 2 is 160 cause the negatives cancel out
Answer:
4x
Step-by-step explanation:
It would be 4x because you have no value given of the variable "X"
therefore, your answer would just be adding the x to the 4 making it 4x
hope this helped!

Answer:
x =8
y = 4sqrt(2)
z = 4sqrt(2)
Step-by-step explanation:
The easiest one to calculate is x
If it is a 45 -45-90 degree triangle then AB = BC=x
Since AB =8 then BC =8 and x=8
The next easiest to calculate is z
If it is a 45 -45-90 degree triangle then AD = BD=z
Using the Pythagorean theorem
z^2 +z^2 = 8^2
2z^2 =64
Divide by 2
x^2 = 32
Taking the square root of each side
z = sqrt(16)sqrt(2)
z=4sqrt(2)
Finally, we can find y
If it is a 45 -45-90 degree triangle then BD = DC
BD =z =4 sqrt(2) = DC = y
Therefore y =4 sqrt(2)
1. **A(x)=(f(x)-f(a))/(x-a)
<span>
<span>*A is the name of this average rate of change function
*x - a represents the change in the input of the function f
<span> *f(x) - f(a) represents the change in the function f as the input changes from a to x
From table: f(5)=-2
f(9)=14
(f(5)-f(9))/(5-9)=(-2-14)/-4=4
</span></span></span><span>The average rate of change of over the interval from x = 5 to x = 9 is 4.
2. f(x)=4x²+6x, g(x)=2x²+13x+1
(f/g)(x)=(4x²+6x)/(2x²+13x+1)
Using the table of values- x:4,5,6,7,8,9
f(x): 88/85,155/116,180/151,238/190,304/233,378/280
3. f(x)=x²-6x+8, g(x)=x-2
f(x)=g(x)⇒x²-6x+8=x-2⇒x²-6x-x+8+2=0, x²-7x+10=0
x₁,₂=(7⁺₋√(7²-4*10))/2=(7⁺₋3)/2
x₁=5, x₂=2
Using the table of values solution is x=5 because 2 doesn't exist in the table of values.
