How do you write this equation in y=ax^2+bx+c ?

Answers

Step-by-step explanation:

y = (x-1)(2x-1)

= x(2x-1) -1(2x-1)

Zwelibanzi and Jessica are friends. Zwelibanzi takes Jessica’s civil technology test paper and will not tell her what her mark is. He knows Jessica dislikes word problems so he decides to tease her. Zwelibanzi says: : I have 12 marks more than you do and the sum of both our marks are equal to 148. What are our marks?

Answers

Answer:

80 and 68

Step-by-step explanation:

Jessica's marks = x

Zwelibanzi's marks = y

We get following equations as per given:

y - x = 12
y + x = 148

Sum up the two equations to substitute x:

2y = 12+148
2y = 160
y = 160/2
y = 80

And finding the value of x:

x = y -12
x = 80 -12
x = 68

Marks are:80 and 68

remember you can do antying to an equaitn as long as you do it to both sides
treat as equaiton, but flip sign when dividng or muliplying by negaitve

isolate x
first distribute
7+3x<8(3+x)
7+3x<24+8x
minus 3x both sides
7<24+5x
minus 24 both sides
-17<5x
divide both sides by 5
-17/5<x
