Given f(x) = | – 5 – 4x| ,find the following:

jasenka [17]

Answer:

$f(10) = 35 \\ \\ f( - 11) = 39 \\ \\ f(12) = 53 \\ \\ f(2) = 13$

Step-by-step explanation:

$f(x) = | - 5 - 4x|$

To solve for the following substitute the value of x in the brackets into the above formula and solve for the value of x

NB:  Absolute value of a negative number is the same number but positive.

So we have

$f( - 10) = | - 5 - 4( - 10)| \\ = | - 5 + 40| = 35 \\ \\ f( - 11) = | - 5 - 4( - 11)| \\ = | - 5 + 44| = 39 \\ \\ f(12) = | - 5 - 4(12)| \\ = | - 5 - 48| \\ = | - 53| = 53 \\ \\ f(2) = | - 5 - 4(2)| \\ = | - 5 - 8| = | - 13| \\ = 13$

Hope this helps you

If (a+bi)^2=2abi, what must be the relationship between a and b? Show or explain your reasoning.

Klio2033 [76]

$(a+bi)^2 =(a+bi)(a+bi)= a^2 +2abi+b^2 i^2 \\ \\ i^2 = -1 \\ \\ (a+bi)^2 = a^2-b^2 +2abi = 2abi \\ \\ a^2 -b^2 = 0 \\ \\ a^2 = b^2 \\ \\ a = b$

For the statement to be true, 'a' and 'b' must be equal

*First expand the binomial using FOIL, then set it equal to whats given "2abi".
Then you can find the relationship between a and b.
