How do I get the value of a function?

Mathematics
1 answer:
Len [333]3 years ago
5 0

Answer: f(x)=mx+b

f(x)=x+7

if x=2 then

f(2)=2+7=9

A function is linear if it can be defined by

f(x)=mx+b

f(x) is the value of the function.

m is the slope of the line.

b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

x is the value of the x-coordinate.

Doss [256]

Answer:

y=-1/7x + 12/7

Step-by-step explanation:

Start by finding the slope

m=(1-0)/(-5-2)

m=-1/7

next plug the slope and the point (-5,1) into point slope formula

y-y1=m(x-x1)

y1=1

x1= -5

m=-1/7

y- 1 = -1/7(x - -5)

y-1=-1/7(x+5)

Distribute -1/7 first

y- 1=-1/7x + 5/7

Add 1 on both sides, but since its a fraction add 7/7

y=-1/7x + (5/7+7/7)

y=-1/7x+12/7

Masteriza [31]

Answer:

63 Lights

Step-by-step explanation:

First you can convert the feet to inches:

The length of decorative lights is 264 inches

You can then subtract 16 from 264

264 - 16 = 248

248/4 = 62

Adding one extra light at the end of the string of decorative lights you can get 63 lights on the string
