MUST SHOW WORK. <br> please do this ASAP!<br> This is about numerical expressions!
lara31 [8.8K]

\huge\text{Hey there!}

\mathsf{2(4 - 1)^2 - 3 + 2(5)}

\mathsf{4 - 1 = \bf 3}

\mathsf{= 2(3^2) - 3 + 2(5)}

\mathsf{3^2}\\\mathsf{= 3\times3}\\\mathsf{= \bf 9}

\mathsf{= 2(9) - 3 + 2(5)}

\mathsf{2(9)}\\\mathsf{= \bf 18}

\mathsf{= 18 - 3 + 2(5)}

\mathsf{18 - 3}\\\mathsf{= \bf 15}

\mathsf{= 15 + 2(5)}

\mathsf{2(5)}\\\mathsf{= \bf 10}

\mathsf{= 15 + 10}\\\mathsf{= \bf 25}

\boxed{\boxed{\huge\text{Therefore, your ANSWER is: \textsf{25}}}}\huge\checkmark

Find the equation of the line that is parallel to the line <img src="https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B3%7D%7B2%7Dx%2
ivann1987 [24]

A line parallel to your equation has the same slope, so it should be in the form:


y = (-3/2)x + b


To figure what "b" has to be, plug in the point (4,0) and solve:

0 = (-3/2)*4 + b

0 = -6 + b

6 = b

So the equation of the line is:

y = (-3/2)x + 6
