Let f(x)=x^2-5x-36.

Answer:

9 and -4

Step-by-step explanation:

Find two numbers that multiply to be -36 and add to be -5.

That is -9 and 4.

So the factored form of x^2-5x-36 is (x-9)(x+4)

So the x-intercepts are 9 and -4

1.1x+1.2x−5.4=−10 x=
katrin [286]

1.1x+1.2x-5.4=-10x

Move all terms to the left:

1.1x+1.2x-5.4-(-10x)=0

Add all the numbers together, and all the variables

2.3x-(-10x)-5.4=0

Get rid of parentheses

2.3x+10x-5.4=0

Add all the numbers together, and all the variables

12.3x-5.4=0

Move all terms containing x to the left, all other terms to the right

12.3x=5.4

x=5.4/12.3

x=3.8571428571429/8.7857142857143

Hope it helps!

Units are simplified first when measurements are multiplied because the units can sometime be very large or small and do not have to be exact when measurements are precise.
