Answer:
Step-by-step explanation:
In order to find the slope of this equation, we can convert it into slope-intercept form, where we can find the slope more easily.
Slope intercept form is usually in the form 
, where m is the slope and b is the y-intercept.
Let's algebraically manipulate this problem so we solve for y.
<em>(Subtract 7x from both sides)</em>
<em>(Divide both sides by -2)</em> 
<em>(Rearrange the equation</em>)
From here, we can now see our equation is , in the form . Since m is the slope, and 
is m, our slope is .

Answer:
<h2>2x + 3</h2>
Step-by-step explanation:
f(2x) means that we have to substitute x with 2x
So, the answer is
2x + 3
Multiply each term by a^2b^2:-
b^2y^2 + a^2x^2 = a^2b^2
subtract a^2x^2 from both sides
b^2y^2 = a^2b^2 - a^2x^2
Now divide both sides by b^2
y^2 = a^2 - a^2x^2 / b^2 = a^2 (1 - x^2/b^2)
take positive square root ( because y > 0)
y = a sqrt(1 - x^2/b^2)
1) P=2w +2l
46=2w +14
32=2w
16= w or width
2) A=lw
A=7 x 12
A= 84
3) A= 12 x 21
A= 252
