What is the slope intercept form when m = 1/2 & b = 89 ?<br> Helppppppppp

Zina [86]

Answer:

$y = \frac{1}{2}x + 89$

Step-by-step explanation:

slope-intercept form: y = mx + b

y = (x , y)

x = (x , y)

m = slope = 1/2

b = y-intercept = 89

Plug in the corresponding numbers & variables to the corresponding variables:

y = (1/2)x + 89

$y = \frac{1}{2}x + 89$ is your answer.

Two lighthouses can be seen from the top of the hill the first flashes once every six seconds and the other flashes once every 1

mote1985 [20]

Answer:

30 seconds

Step-by-step explanation:

Find the least common multiple of 6 and 15.

First, write the prime factorizations.

6 = 2 × 3

15 = 3 × 5

The LCM is the product of each distinct factor.

LCM = 2 × 3 × 5

LCM = 30

They flash together at the same time every 30 seconds.
