Step-by-step explanation:

$here \: given \: that \: total \: lenth = bd = 67 \\ then \: bd = bc + cd \\ so \: we \: can \: write \: that \\ 67 = 3x - 2 + 4x + 13 \\67 = 3x + 4x - 2 + 13 \\ 67 = 7x + 11 \\ 7x = 67 - 11 \\ 7x = 56 \\ x = \frac{56}{7} \\ x = 8 \\ thankyou$

Answer:

$\huge\boxed{\sf 22}$

Step-by-step explanation:

By looking at the line segment, we get to know that:

BD = BC + CD

<u>Given that:</u>

BD = 67

BC = 3x - 2

CD = 4x + 13

<u>Solution:</u>

Put the givens in the above equation made.

67 = 3x - 2 + 4x + 13

67 = 3x + 4x - 2 + 13

67 = 7x + 11

7x = 67 - 11

7x = 56

Divide both sides by 7

x = 56 / 7

x = 8

<u>Now, Finding BC:</u>

= 3x - 2

Put x = 8

= 3(8) - 2

= 24 - 2

= 22

$\rule[225]{225}{2}$

The area of a playground is 204 yd^2 the width of thr playground is 5 yd longer that its length what the length and the width of

morpeh [17]

W= width= L+5
L= length
Area= 204

Area= LW
204 square yards= LW
substitute w=L+5 for w
204= (L)(L+5)
204= L^2 + 5L
subtract 204 from both sides
0= L^2 + 5L - 204
factor
0= (L+17)(L-12)

0= L+17
-17= L

0= L-12
12 yards= L

WIDTH
Since the area cannot be a negative number, we'll use L=12 to find the width.

w=L+5
w=12+5
w=17 yards

CHECK:
204=(12)(17)
204=204

ANSWER: The length is 12 yards and the width is 17 yards.

Hope this helps! :)

Use Newton’s Method to find the solution to the equation

Scorpion4ik [409]

$f(x) = - x {}^{2} + 18 \\ f'(x) = - 2x$

$x_{n + 1} = x_{n} - \frac{f(x_{n})}{f'(x_{n})}$

$x_{2} = 3 - \frac{f(3)}{f'(3)} = 4.5$

$x _{3}= 4.5 - \frac{f(4.5)}{f'(4.5)} = 4.25$

$x_{4} = 4.25 - \frac{f(4.25)}{f'(4.25)} ≈4.242647$

$x_{5} = 4.242647 - \frac{f(4.242647)}{f'(4.242647)} ≈4.242640 \\$

A line includes the points (4,1) and (8, 2). What is its equation in slope-intercept form?

Alisiya [41]

Answer:

$y = \frac{1}{4} x$

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula $m= \frac{y_2-y_1}{x_2-x_1}$ . Substitute the x and y values of the given points into the formula and solve:

$m = \frac{(2)-(1)}{(8)-(4)} \\m = \frac{2-1}{8-4}\\m = \frac{1}{4}$

Thus, the slope is $\frac{1}{4}$ .

2) Now, use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation in point-slope form (from there we can convert it to slope-intercept). Substitute values for $m$ , $x_1$ , and $y_1$ .

Since $m$ represents the slope, substitute $\frac{1}{4}$ for it. Since $x_1$ and $y_1$ represent the x and y values of one point the line intersects, choose any of the given points (it doesn't matter which one, the end result will be the same) and substitute its x and y values into the formula as well. (I chose (4,1), as seen below.) Then, isolate y to put the equation in slope-intercept form and find the answer.

$y-(1) = \frac{1}{4} (x-4)\\y-1 = \frac{1}{4} x-1\\y = \frac{1}{4} x+0\\y=\frac{1}{4}x$

What is 3+16-2×0+1 ?

nikitadnepr [17]

<em><u>Answer: =20 *The answer should be positive sign.*</u></em>

Step-by-step explanation:

This question it's about PEMDAS. This lesson it's about order of operations. p-parenthesis, e-exponents, m-multiply, d-divide, a-add, and s-subtract. It can also go left to right.

do multiply first left to right.

2*0=0

3+16-0+1

add/subtract left to right.

3+16=19

19-0+1

19-0=19

19+1

19+1=20

<u><em>=20</em></u>

Hope this helps!

Thanks!

Have a great day!
