5a - 10b = 45 when b = 3, then

5a - (10*3) =45
5a - 30 = 45
5a = 45+ 30
5a = 75
a = 75/5
a =15

Well, since you have the value of b, the first thing you want to do is substitute that value in for b.

5a - 10(3) = 45

10*3 = 30

5a - 30 = 45

Now, to get the variable by itself (a) you have to + 30 because you have to reverse the subtraction.

5a = 75

Now, you divide by 5 to finish getting a by itself.

a = 15

Hope this helps!

A nature preserve opened with a population of 6 rabbits. After one year, the number of rabbits had doubled. The year after that,
mina [271]

Answer:And Explanation

Initially the number of rabbits in the preserve are: 6

After one year the population of rabbits are doubled this means that the population of rabbits at the end of one year is: 2×6=12

Again after one year the population of rabbits are doubled this mean that at the end of second year the population of rabbits are: 12×2=24

and at the end of third year the population of rabbits is: 24×2=48

Hence, the points are plotted as follows:

 (0,6)

 (1,12)

 (2,24)

and (3,48)

We know that the y-intercept is the point where x-value is zero.

Hence, here we have y-intercept at (0,6
