Hello everyone,
I have a question about an exercise in the book.
A linear equation is given in the short form:
c) x= 1/2, d) y=5, e) x=-1
The number pairs: (1I5), (-12I-1), (5I2), (5I-1)
I know I should write down the short form in a detailed linear equation y=m*x+y but I don't know how to proceed. Can someone explain to me step by step how to find a solution?

Loading...Hello, I'm having trouble understanding this equation. 😅 In all steps, only a certain number is divided or multiplied by the number on the right-hand side, but shouldn't everything on this side be divided or multiplied by the value on the right-hand side? 🤔 For example, with |:2, only the 2/3 is divided by 2….
F(x) = (2-x^2) / (x^2-9) I get a WP at plus and minus root 3, but it does not meet the sufficient condition. Are they wp?
Task was 5x + 7 = 3x + 25 My result and calculation: If not, please explain to me how and where I could improve and how you can immediately recognize my mistake.
Hi I'm currently practicing something and have found an exercise: fa(x) = x – a^2x^3 I have calculated everything so far, including the zeros at 0 and 1/a. turning points at 1 and 1- a^2 hope that's right 🙂 Now I want to calculate the extreme points, but unfortunately I can't do it. Could someone…
überall bei x = gibt es kein m und auch kein b
In die Form y = mx+b kann man sie nicht bringen
x = 5
sagt schon die Lösungen
5 2 und 5 -1
.
x = 1/2 und x = -1 haben keines der Zahlenpaare als Lösung
zb
bei a) x=5 also hast du nur eine senkrechte linie, die den punkt (5/-1), (5/2) schneidet (zeichne ein koordinatensystem dann sieht man das einfacher)
b) y=-1 hast du den 2ten und den 3ten punkt (zeichne es bro)
c) keins glaube
d) nur den ersten
e) auch keins 😉
