8 0

Answer:

-8n+7

Step-by-step explanation:

the difference between the values is 8, as it decreases by 8, it withh be 8n

It does not start at 8 though, so you do 15-8 to find the different which is added on which is 7 in this case

Write an equation in slope-intercept form for the line with slope 3 that contains the point (5,-1).

Pavlova-9 [17]

Answer:

y = 3x-16

Step-by-step explanation:

We know the slope and a point , so we can use the point slope form of the equation for a line

y-y1 = m(x-x1) where the slope is m and the point is (x1,y1)

y--1 = 3(x-5)

y+1 = 3(x-5)

We need to rearrange the equation into slope intercept form y=mx+b

First distribute the 3

y+1 =3x-15

Then subtract 1 from each side

y+1-1 =3x-15-1

y = 3x-16

This is in slope intercept form

Find the midline for f(x)=−2+4cosx.

diamong [38]

The mid-line for f(x) = 4cos x is y = 0. In the given equation, the term -2 is described as the y-shift. Therefore the mid-line for f(x) = -2 + 4cos x is:
y = -2.

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,160 ft Determine the flag's width and

Illusion [34]

The length of flag is 760 feet and width of flag is 320 feet

Solution:

A seed company planted a floral mosaic of a national flag

Since, the flag is generally of shape rectangle, we can use the formula of rectangle

Let "a" be the length of rectangle

Let "b" be the width of rectangle

The length is 440 ft greater than the width

Length = 440 + width

a = 440 + b ----- eqn 1

The perimeter of the flag is 2,160 ft

The perimeter of rectangle is given as:

Perimeter = 2(length + width)

Substituting the given values, we get

2160 = 2(440 + b + b)

2160 = 880 + 4b

4b = 2160 - 880

4b = 1280

b = 320

Substitute b = 320 in eqn 1

a = 440 + 320

a = 760

Thus the length of flag is 760 feet and width of flag is 320 feet
