Answer:
I can't see Mathieu's work but I will show the right steps and maybe you can find where Mathieu went wrong.
f(x)=x^2+4x+3
f(x)=(x+3)(x+1) Since 3*1=3 and 3+1=4
The x-intercepts can be found by setting y to 0 and solving for x
(in other words replace that f(x) thing with 0 and solve for x)
0=(x+3)(x+1)
Now set both factors equal to 0
x+3=0 or x+1=0
x =-3 x=-1
The x-intercepts are at (-3,0) and (-1,0)
Answer: 80
Step-by-step explanation:
Let the number of students be represented by x
Let the number of faculty be represented by y.
Based on the information in the question, we can form an equation which will be:
x + y = 100 ..... i
10x + 25y = 1300 ....... ii
From equation i,
Make y the subject of the formula
y = 100 - x ...... iii
Put the value of equation iii into ii
10x + 25y = 1300
10x + 25(100 - x) = 1300
10x + 2500 - 25x = 1300
10x - 25x = 1300 - 2500
-15x = -1200
x = 1200/15
x = 80
