A fencing company charges $22per foot to install a wood fence around a rectangular pool area that is 20 feet wide and 38 feet lo
pantera1 [17]
We will need to find the perimeter here, since in this context we’re talking about fencing around a rectangular pool. The formula for perimeter is P = 2L + 2W. The L and W can stand for length/width which is the same as wide/long in this problem. I will now plug in the numbers. P = 2(38) + 2(20) which gives us 76 + 40. 76 + 40 is 116. Therefore, the perimeter is 116 ft.

I know that the fencing company charges $22 per foot. I can multiply 116 x 22 to give me $2552. The answer is $2552.

What is the solution to the equation 1/2 x + 3 = 2/3 x + 1​
Leni [432]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

\frac{1}{2} x + 3 =  \frac{2}{3} x + 1 \\

Subtract sides 3

\frac{1}{2} x + 3 - 3 =  \frac{2}{3} x + 1 - 3 \\

\frac{1}{2} x =  \frac{2}{3} x - 2 \\

Multiply sides by 6

6 \times  \frac{1}{2} x = 6 \times  \frac{2}{3} x + 6 \times ( - 2) \\

3x = 4x - 12

Subtract sides 4x

- 4x + 3x =  - 4x + 4x - 12

- x =  - 12

Negatives simplifies

x = 12

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

CHECK :

\frac{1}{2} (12) + 3 =  \frac{2}{3} (12) + 1 \\

6 + 3 = 8 + 1

9 = 9

Thus the solution is correct .

Can someone help me solve this?
serg [7]

Answer:

(a) y = -3/5 x + 13/5

(b) y = 5/3 x + 1/3

Step-by-step explanation:

(a) The slope of the tangent line is dy/dx.  Use implicit differentiation:

x² + y² + 4x + 6y − 21 = 0

2x + 2y dy/dx + 4 + 6 dy/x = 0

2x + 4 + (2y + 6) dy/dx = 0

x + 2 + (y + 3) dy/dx = 0

(y + 3) dy/dx = -(x + 2)

dy/dx = -(x + 2) / (y + 3)

At the point (1, 2), the slope is:

dy/dx = -(1 + 2) / (2 + 3)

dy/dx = -3/5

Using point-slope form of a line:

y − 2 = -3/5 (x − 1)

Simplifying to slope-intercept form:

y − 2 = -3/5 x + 3/5

y = -3/5 x + 13/5

(b) The normal line is perpendicular to the tangent line, so its slope is 5/3.  It also passes through the point (1, 2), so point-slope form of the line is:

y − 2 = 5/3 (x − 1)

Simplifying to slope-intercept form:

y − 2 = 5/3 x − 5/3

y = 5/3 x + 1/3

Will give the brainiest!!

-2. The slope of a function is measured by rise over run. The rise from one point to another is 2 but the run goes towards the left 1 meaning it is negative. 2/-1=-2
