We are looking to find the point where the curve discontinued

Step 1: Factorise both numerator and denominator (if possible)
$\frac{x+5}{ x^{2} +3x-10}= \frac{(x+5)}{(x+5)(x-2)}$

Step 2: Recognise the common factor, which is $(x+5)$

Step 3: Equate the common factor to 0

Inequality word problem 7 less than -2 times a number X is greater than or equal to 41

Lady bird [3.3K]

Less than means minus so 7 less than means -7

-2 times a number x means -2 times x or -2x

is greater than or equal to means >

41=41

so
-7+-2x>41
-2x-7>41
add 7 to both sides
-2x>48
divide both sides by -2
remember to flip sign since divided by negative
x<-96
