help pls am confused
Answer:
Given, x−x1=5
Squaring both the sides,
⇒(x−x1)2=52
⇒x2+x21−2(x)(x1)=25
⇒x2+x21=25+2
⇒x2+x21=27
Now,
x3−x31
=(x−x1)[(x)2+(x1)2+(x)(x1)]
=5(27+1)
=140

Answer:
322
Step-by-step explanation:
Consider the cube ...
(a +b)³ = a³ +3a²b +3ab² +b³
= a³ +b³ +3ab(a+b)
Now, for a=x and b=1/x, we have ...
(x +1/x)³ = x³ +1/x³ +3(x)(1/x)(x +1/x)
Using the known value for x+1/x, this is ...
7³ = x³ +1/x³ +3(7)
x³ +1/x³ = 7³ -3·7 = 343 -21
x³ +1/x³ = 322

Explain how to make this an expression
176.3- 15.75
Answer:
I have that same question on my extra credit!
Step-by-step explanation:
I know the answer its 160.55 but I don't know what i should do for the problem. This is my questions:
Mina asked four friends to explain how each one solved the expression . Here are their explanations Please comment if these are the same:
Ivy’s explanation: I lined up the numbers to subtract.
176.3
- 15.75
18.8
Hannah’s explanation: I lined up the two decimals according to place value. I put a 0 in the hundredths place to make it easier for me to subtract.
176.30
- 15.75_
161.45
Jose’s explanation: I lined up the two decimals according to place value.
176.3
- 15.75
161.45
An’s explanation: I counted up from 15.75 to 176.3 to find the difference. I underlined each number I added on each line.
15.75 + 0.25 = 16
16 + 4 = 20
20 + 150 = 170
170 + 6 = 176
176 + 0.3 = 176.3
I rearranged the underlined numbers to make them easier to add: .
150 + 6 + 3 + 0.25 = 163.25

Evaluate y(-7) + 9x
When x = -6, y = 7
Answer:
-103
Step-by-step explanation:
Answer: -103
Step-by-step explanation:
y=7 so 7x(-7)= -49 because a negative times a positive always equals a negative. Same thing for 9x. x=(-6) so 9x(-6)=-54. So (-49)+(-54)= -103

I NEED HELP WITH THIS QUESTION!!
Answer:
- 1
Step-by-step explanation:
The product of the slopes of lines perpendicular to each other is - 1
Given y = 4x - 5 with slope 4
y = - [tex]\frac{1}{4}[/tex] x - 5 with slope - [tex]\frac{1}{4}[/tex] then
4 × - [tex]\frac{1}{4}[/tex] = - 1 proving the lines are perpendicular
where do i put the lines ? also is it a function
okay if I'm doing this right then

Answer: x=12
Step-by-step explanation:
20 squared= 400 and 16 squared= 256. The Protagorean Theorm is a sqaured plus b sqaured equals c squared. You just reverse the Theorm to C sqaured minus B squared= A squared. 400-256=144 (12x12= 144)

Find AC if BC=11x-1, AC=21x, and AB=11.
Is that the right answer ?
Answer:
Yes, that is correct
Step-by-step explanation:
The formula for the slope can be referred to as "rise over run", a fraction where the rise (change in the y direction) is divided by the run (change in the x direction).
We can get the rise and run by choosing two points on the slope and looking for the change in the x and y direction. In this case, let us use the points (-4,0) and (0,-5). The change in the y direction is from 0 to -5, thus the rise will be -5. Likewise, the change change in the x direction is from -4 to 0 and the run will be 4.
Going back to "rise over run", we divide the rise by the run, giving us -5/4
