Answer:

Step-by-step explanation:

You need to get w on one side by itself.

Start out by subtracting 2l from both sides.

p−2l=2w.

Now since w is being multiplied by 2 we need to divided both sides (all terms) by 2.

w=p2−I

Answer:

W=P-L

Step-by-step explanation:

P=2L+2W

Subtract 2L from both sides.

P-2L=2W

Divide both sides by 2

P-L=W

For what value of the constant c is the function fcontinuous on (−[infinity], [infinity])?

Arlecino [84]

Answer:

For $c=\frac{1}{7}$ the function f(x) is continuous on $(-\infty,\infty)$ .

Step-by-step explanation:

We have the following function

$f(x) = \left\{ \begin{array}{ll} cx^2+5x & \quad x$

For the function f(x) to be continuous on $(-\infty,\infty)$ it is sufficient to have continuity at x = 6, we need to ensure that as x approaches 6, the left and right limits match, this means that

$\lim_{x \to 6^{-} } f(x)=\lim_{x \to 6^{+} } f(x)=f(x)$ ,

which holds if and only if

$c\left(6\right)^2+5\left(6\right)=\left(6\right)^2-c\left(6\right)\\36c+30=36-6c\\42c=6$

namely if $c=\frac{1}{7}$ .

What is the solution to the equation 1.25 + r = 4? r = 2.75 r = 3.75 r = 5.25 r = 5.75

eimsori [14]

Answer:

r = 2.75

Step-by-step explanation:

1.25 + r = 4

Subtract 1.25 on both sides.

1.25 + r - 1.25 = 4 - 1.25

r = 4 - 1.25

r = 2.75

The solution to the equation is r = 2.75.
