Answer:

- The value of both expressions when t = 3 is 30

- The value of both expressions when t = 7 is 54

- The expressions are equivalent

Step-by-step explanation:

Plug in each value of t into the expressions:

6t + 12, when t = 3 equals 30

6t + 12, when t = 7 equals 54

6(t + 2), when t = 3 equals 30

6(t + 2), when t = 7 equals 54

We have the same answers for both expressions, meaning they are equivalent.

Answer: 3rd, 4th, and 5th are correct.

Step-by-step explanation:

We know that the equation 6(t+2) can be simplified to 6*t+6*2, also 6t+12. This causes any statements saying a variable with a certain value applies to one side also applies to the other.

Answer:

[26, -32]

Step-by-step explanation:

7[-y - 6] + 6y = -10

-7y - 42 + 6y = -10

-y - 42 = -10

+ 42 + 42

____________

-y = 32

-32 = y [Plug this back into both equations to get the x-value of 26]; 26 = x

(-1,4) (2,2) find midpoint?

notsponge [240]

$\text{Hey there!}$

$\text{The midpoint formula is: }\dfrac{\mathsf{x_2+x_1}}{2}, \dfrac{\mathsf{y_2+y_1}}{2}$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

$\mathsf{x_1 = -1}\\\\\mathsf{x_2=2}\\\\\mathsf{y_1=4}\\\\\mathsf{y_2=2}$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

$\dfrac{2-1}{2}\\\\\mathsf{2-1 = 1}\\\\\mathsf{2=2}\\\\\\\mathsf{x = \dfrac{\mathsf{1}}{2}}$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

$\mathsf{\dfrac{4+2}{2}}\\\\\mathsf{4+2=6}\\\\\mathsf{2=2}\\\\\mathsf{\dfrac{6}{2}=3}\\\\\\\mathsf{y=3}$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

$\boxed{\boxed{\text{Thus,\ your\ answer\ is:\boxed{(\dfrac{1}{2\ },\ 3)}}}}\checkmark$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
