since you already know how to get the slopes and equation, let's do the equations of each of these two without much fuss.
then we'll have two equations, namely a <u>system of equations of two variables</u>, and we'll solve it by <u>substitution</u>.
first equation is
second equation is
now, let's recall, let's substitute "y" in the second equation,
Since q(x) is inside p(x), find the x-value that results in q(x) = 1/4
so we conclude that
therefore
plug
into p( q(x) ) to get answer
To convert a decimal to a percent, multiply the decimal by 100, then add on the % symbol. An easy way to multiply a decimal by 100 is to move the decimal point two places to the right.
Answer:
