Answer:

(-\frac{3}{7}, 0) -- x intercept

(0,3) -- y intercept

Step-by-step explanation:

Given

y = 7x + 3

Required

Determine the x and y intercept

For x intercept.

Set y = 0

So, we have:

y = 7x + 3

0 = 7x + 3

Collect Like Terms

7x = -3

Make x the subject

x = -\frac{3}{7}

Hence, the x intercept is: (-\frac{3}{7}, 0)

For the y intercept;

Set x = 0

So, we have:

y = 7x + 3

y = 7*0 + 3

y = 0 + 3

y = 3

Hence, the y intercept is: (0,3)

The population of rabbits in a national forest is modeled by the formula P= 12,000 + 1000 (t+1) where t is the number of years f
V125BC [204]
In this formula, 1000(t+1) represents the growth rate of the rabbits.  We want the number right now, so sub in 0 for t.

P=12,000+1000(0+1)
P=12,000+1000
P=13,000 rabbits.
Hope this helps!!!
