The perimeter of a rectangle is 46 inches. Find the dimensions if the length is 5 inches greater than twice the width.

Answers

Answer:

6

Step-by-step explanation:

W = x

L = 2x - 5

P = 2W + 2L

46 = 2(x) + 2(2x - 5)

46 = 2x + 4x - 10

46 = 6x - 10

46 + 10 = 6x

36 = 6x

x = 6

Use the point-slope formula to write an equation of the line that passes through (6,23) and has a slope of m= 3. Write the answer in slope-intercept form
possible).

Answers

y=3x+5

plug your coordinate points into the equation for slope (left corner or the paper)

multiply by the denominator on both sides of the equation

x-6 cancels out and leaves y-23=3(x-6)

multiply x and -6 by 3

add 23 to both sides to isolate y

if 1 ft = 1.894 x 10​ -4​miles, convert 20.0 inches to miles

Answers

Answer:

3.1567 * 10^-4 miles

Step-by-step explanation:

1 ft = 1.894 * 10^-4 miles , so

1 inch = 1.894 * 10^-4 / 12  miles

= 0.15783 * 10^-4

= 1.5783* 10^-5 miles  ( in scientific form).

Multiplying this by 20 we get

31.567 * 10^-5

= 3.1567 * 10^-4 miles.

Answers

f(x)

(2, 0) and (3, 2)

m = y - y1

x - x1

m = 2 - 0

3 - 2

m = 2

y - y1 = m(x - x1)

y - 0 = 2(x - 2)

y = 2x - 4

f(x) = 2x - 4

g(x)

(2/3, 0) and (1, 2)

m = y - y1

x - x1

m = 2 - 0

1 - 2/3

m = 6

y - y1 = m(x - x1)

y - 2 = 6(x - 1)

y = 6x - 4

g(x) = 6x - 4

since both equations are linear that means the graphs will be straight lines with y-intercept being -4 for both of the graphs.

if,

g(x) = f(k*x)

f(x) = 2x - 4

f(k*x) = 2k*x - 4

6x - 4 = 2k*x - 4

6x = 2kx

6 = 2k

k = 3.

I hope the answer is correct. All the best!

Step-by-step explanation:

There is always 180 degrees in angles.

[ X ]

180 - 65 = 115

How can I find 75% of any number?

Answers

Answer:

75% can be converted into a decimal, any percentage can.

Once converted, 75% is actually .75

At this point you can move the decimal place two place up, and put it over 100, in a fractal form

75/100  

You can then simplify this to

3/4  

You can then use this fraction as a conversion factor with any number, for example if we took the number 8

8∗3/4  

2∗3/1=6

Divide it into 75 groups
