Free points! What is 2/3 / (-5/6)?
weeeeeb [17]
2/3 ÷ (-5/6)

When dividing fractions, all you really have to do is multiply the first fraction by the second fraction's reciprocal.

Remember, a reciprocal is the fraction/whole number flipped.

Ex : 4/6 turns into 6/4

So, the reciprocal of -5/6 is -6/5

Therefore, our new equation looks like this :

2/3 × -6/5

Multiply the numerators with the numerators, and the denominators with the denominators :)

Numerators : 2 × -6 = -12

Denominators : 3 × 5 = 15

SO, our answer is -12/15

Simplify this.

-4/5

~Hope I helped!~

Mathieu is finding the x-intercepts of the function f(x)=x^2+4x+3. His world is shown below. (In the photo) The Answer is: (He s
navik [9.2K]

Answer:

X intercepts are points where a function intersects or cuts through the x axis where y=0.

Step-by-step explanation:

In the function given which is f(x) =x^2 +4x + 3 we see that this is a parabola of which when the graph is drawn it has a U shape so when finding x intercepts of this function it is those points on the function where the graph cuts the x axis and at those two points f(x)= 0, so here Mathieu had made a mistake of factorizing and equating the x intercepts for this function.

For finding the X intercepts let f(x) = 0

therefore 0= x^2 + 4x + 3  now we solve for x

0= (x+1)(x+3)  

(x+1)= 0 or (x+3)=0

therefore x=-1 or x=-3

now if you substitute these values onto the function they give f(x)= 0,

f(-1) = (-1)^2 + 4(-1) + 3 = 0

f(-3) = (-3)^2 + $(-3) + 3 =0

now let us look at Mathieus answer which is x+1 = x+3 yes these x values do give the same y value but they are not equal because if you can actually solve this further you would not get a defined answer. Both these are factors of the function but are not actually equal as the function would not be able to be drawn if this was the case.

PLEASE HELP PLS!!!!!

Subtitute f(x) with 2x + 1, and subtitute g(x) = -x + 4
f(x) = g(x)
2x + 1 = -x + 4

Then solve the equation above to find the value of x
Move the coefficient-variable x to the left side, and move the constants to the right side. When they are moved, addition becomes substraction, substraction becomes addition
2x + 1 = -x + 4
2x + x = 4 - 1

Simplify the equation
2x + x = 4 - 1
3x = 3

Move 3 on the left side to the right side, it becomes denominator
3x = 3
  x = 3/3
  x = 1

The solution to the equation is
x = 1
