Mathematics

sukhopar [10]3 years ago

Answer:

Step-by-step explanation:

We can see that we need to plug in 2 for x in the first equation

We can also see that when x=2 we need to use the second part of the piecewise (because this one works when x is greater than <em>or equal to</em> 2)

so we have

3*(4*2+1)= 27

for g(x) we need to plug in x=1

we use the first piecewise equation because it's valid when x is less than 3

4(1²+2)=12

take their sum 27+12= 39

20/4=5

A student claims that 3x + 2y = 5xy. Use a visual representation to show whether this is true or false
Ket [755]

Answer:

It is true, except when x = 2/5, since it is an asymptote.

Step-by-step explanation:

3x=5xy-2y

3x=y(5x-2)

3x/5x-2=y

5x-2=0 -------> 5x=2 --------> x=2/5
