X3-7x=6x-12
x3-7x-6x+12=0
x3-13x+12=0
(x-1)(x2+x-12)=0
Calculate delta of the second bracket:
delta = 1+4*12=49
sqrt(delta)=sqrt(49)=7
x_1=(-1-7)/2=-4
x_2=(-1+7)/2=3
(x-1)(x+4)(x-3)=0
Answear:
Roots: x=1, x=-4, x=3.
Answer:
100
Step-by-step explanation:
sum the parts of the ratio, 4 + 5 + 1 = 10 parts
Fiona gets 40 sweets which is 4 parts of the ratio
Divide Fiona's share by 4 to find the value of one part of the ratio
40 ÷ 4 = 10 ← 1 part of the ratio
The total number of sweets is 10 parts , thus
number of sweets in total = 10 × 10 = 100
Answer:
domain: all real numbers
range: y<-2
Step-by-step explanation:
I think its correct but already know the answer sooo yea
You just have to add the three
4/8+3/8+1/8=8/8
8/8=100%
So they finished the whole project
Hope this helps!
Answer:
It's easy
Step-by-step explanation:
An exponential equation always has x as an exponent so just look for it
Ex:x+2=0(quadratic) Ex:2^x=0(exponential)
