11 less than 7 times a number is 5 more than 6 times the number. find the number.

kolezko [41]

Let's translate the words into expressions:

11 less than 7 times a number is $7x-11$

5 more than 6 times the number is $6x+5$

So we have the equation

$7x-11 = 6x+5$

Subtract 6x from both sides:

$x - 11 = 5$

Add 11 to both sides:

$x=16$

F(x) = 5x^3+ 2x^2 - 90x - 36. <br><br> finding all zeros by factoring and explaining the steps

ella [17]

Answer:

f(x)=5x^3-2x^2-90x-36=0

=x^2(5x-2)-18(5x-2)=(x^2-18)(5x-2)=0

x^2-18=0/5x-2=0

x^2=18=x=9√2

5x-2=0

x=2/5

zeros are 9√2,2/5
