Answer:
There's not enough information to determine the answer... is there more to this?
ANSWER : 9 over 4
or 2 and 1/4
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
*3 over 2 x 3 over 2 is 3/2 x 3/2* << this is for me to remember
Okay so multiplying fractions means for us to multiply across. That means if we line the fractions, we multiply. Like this
3 x 3
----- ----- 3 times 3 is = 9
2 x 2 2 times 2 is = 4
9 over 4 is the same thing as 2 and 1/4 << FRACTION

the coordinates where the bridges must be built is
and
.
<u>Step-by-step explanation:</u>
Here we have , a road follows the shape of a parabola f(x)=3x2– 24x + 39. A road that follows the function g(x) = 3x – 15 must cross the stream at point A and then again at point B. Bridges must be built at those points.We need to find Identify the coordinates where the bridges must be built. Let's find out:
Basically we need to find values of x for which f(x) = g(x) :
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Value of g(x) at x = 3 : y=3x -15 = 3(3)-15 = -6
Value of g(x) at x = 6 : y=3x -15 = 3(6)-15 = 3
Therefore , the coordinates where the bridges must be built is
and
