Answer: You use the rules of PEMDAS Parenthesis, Exponents, Multiply, Divide, Add, Subtract

Step-by-step explanation: First solve all equations inside of the parenthesis, so the equation becomes 4(5)-7+2

Then you multiply and the 4 by 5 and the equation becomes 20-7+2

Then you do all the adding and it becomes 20-9

Then subtract and you get 11

How would you graph this????Plz help

mylen [45]

$\bf 2x-5=3\implies 2x=3+5\implies x=\cfrac{8}{2}\implies x=4$

now.. to graph that

let us make a quick table
$\bf \begin{array}{lrlll}
x&y\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
4&-\infty \\
4&-1,000,000,000\\
4&-1,000,000\\
4&-1,000\\
4&-100\\
4&-10\\
4&-1\\
4&0\\
4&1\\
4&10\\
4&100\\
4&1,000\\
4&1,000,000\\
4&1,000,000,000\\
4&+\infty 
\end{array}$

so.. you can either plot those points there on the table,
or just bear in mind x = 4, no matter what "y" is,
namely, x = 4 is just a vertical line at x = 4 :)

What is x?<br><br>x/8 + 6 = 4<br><br>x=_?

Nitella [24]

Answer:x=-16

Step-by-step explanation:

Subtract 6 from both sides

x/8=-2

Multiply the number by 8 on both sides to get x by itself

x=-16
