Answer:
C.
Step-by-step explanation:
recall that the point-slope form of a linear equation is given by
y = mx + c
Rearranging so that it is in the same form as the answer choices, we get
y = c + mx
where m is the slope and c is the y-intercept
we note the following observations
1) The line goes from top left to bottom right, this means that the slope is negative, hence m has to be negative. (in our case, all the choices have negative x)
2) The line crosses the y-axis at y = 4, this means the y-intercept is 4 and hence c = 4.
If we look at the choices, only choice B satisfies both observations (that m is negative and c = 4)
For this case we can make the following rule of three:
4543 -----------> 423970 km ^ 2
x ----------------> 250 km ^ 2
Clearing x we have:
x = (250/423970) * (4543)
x = 2.678845201
Answer:
the population density of mountain lions per 250 kmsquared2 in California is:
x = 2.678845201
nearest whole numberx = 3
Answer:
3.7*10⁷ people.
Step-by-step explanation:
Estimated population of California = 3.9*10⁷ people
Estimated population of Maine = 1.3*10⁶ people.
Let x represent the estimated number of people that live in California more than Maine.
The number of people that live in California more than Maine can be found by finding the difference between the population of California to Maine.
No. Of people living in California - no. Of people living in Maine = estimated no of people that live in California more than Maine.
X = 3.9*10⁷ - 1.3*10⁶
X = 3.7*10⁷ people
About 3.7*10⁷ people live more in California than Maine

25 to 75
25/75 / 5/5 = 5/15 you can divided that number me more time (divid it by 5/5) which give you your answer of 1:3
