Mathieu is finding the x-intercepts of the function f(x) = x2 + 4x + 3. His work is shown below
Alex_Xolod [135]

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)

A group of 100 people, some students, and some faculty attended a museum opening. Each student paid $10 per person for entrance
slava [35]

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

There were 80 students who attended the museum opening
