1) The expressions are not equivalent. When you expand and multiply 2(x + 3) it becomes 2x + 6. This is not equal to 3x + 5

2) They are equivalent. Again, expand and multiply the second expression. 2(3n + 4) becomes 6n + 8. This makes both sides equal.

3) They are equivalent. In the parentheses, you are adding 3 y's and a 2. This gives you 3y + 2. Now add the additional 3y that follows the closed parentheses. You'll have 6y + 2. Now both sides are equivalent.

Mashcka [7]

Answer:

Ques 1:

Let us consider the system of equations,

$2x+y=3$ and $3x-y=2$

It is known that 'The intersection points of the graphs of the system of equations are the solutions of the system of equations'.

So, after plotting the given graphs, we see that from the first graph,

The only intersection point is (1,1).

Thus, the solution of the system is x= 1 and y= 1.

Ques 2:

We have the functions, f(x)= 2x+1 and g(x)= 2x^2+1.

Plotting the graphs of both the functions is shown by graph 2, we see that,

The intersection points are (0,1) and (1,3)

Hence, the function have equal values only at x= 0 and x= 1 but not at x= 3.

6 1/2 divided by 10 1/2

Schach [20]

Answer:

13/21

Step-by-step explanation:

Make 6 1/2 and 10 1/2 and improper fraction

6 1/2=13/2

10 1/2=21/2

K.C.F

Keep 13/2

Change the division symbol to multiplication

Flip 21/2 to 2/21

then multiply across

13*2=26

21*2=42

so the fraction is 26/42 and then simplify the fraction

13/21
