Answer:
y = x + 2
Step-by-step explanation:
Step 1: Find the slope
Step 2: Substitute the slope and a point in to find y intercept
(6)=(1)(4)+b
6 = 4 + b
b = 2
Step 3: Substitute all the information in
y = x + 2
Therefore the equation for a line that passes through (4,6) and (-1,1) is y = x + 2
Write <u>two functions</u> that <u>describes</u> the <u>decrease of the population</u> after <u>t years.</u>
1. In one study, a population of 784 orangutans is expected to decrease at a rate of 25 orangutans per year. Then after t years the number of orngutans will be
2. In a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year. Then after t years the number of orngutans will be
3. Equate right sides of the equations:
Answer: after 3 years
Answer:
x = - 7
Step-by-step explanation:
Using the rule of exponents
×
=
Given
×
= 6², then
= 6²
Since the bases on both sides are equal then equate the exponents
9 + x = 2 ( subtract 9 from both sides )
x = - 7
