a city has a population of 340,000 people suppose each year the population grows by 7% what will rhe population be after 12 year

NemiM [27]

So this is going to be an exponential equation, which the format is $y=ab^x$ , in which a is the initial value and b is the growth/decay rate.

In this case, a is going to be 340,000 and b is going to be 107%, or 1.07, since the population is going to be increasing by 7% and the equation is now $y=340000(1.07)^x$ .

Now replace x with 12 and solve.

$y=340000(1.07)^{12}$

Solve $1.07^{12}$ , and then if you don't round that answer and multiply it with 340000 you get $y=765745$ .

Choose the system of equations which matches the following graph: (5 points) a line includes points 0 comma 0 and negative 1 com

IrinaK [193]

(0,0),(-1,2)
slope = (2 - 0) / (-1 - 0) = - 2/1 = -2

so this equation, since it goes thru the origin, is : y = -2x or 2x + y = 0

(2,3),(1,-2)
slope = (-2 - 3) / (1 - 2) = -5/-1 = 5

y = mx + b
slope(m) = 5
(2,3)...x = 2 and y = 3
now sub into the formula and find b, the y int
3 = 5(2) + b
3 = 10 + b
3 - 10 = b
-7 = b
so this equation is : y = 5x - 7 or 5x - y = 7

so ur 2 equations are :
2x + y = 0
5x - y = 7

How do you solve this?

Sholpan [36]

40% of 60 is 24

To convert from percent to decimal, divide the percent without the percent symbol by 100.

so, 40% = 40/100 = 0.4

40% 60 is just 0.4*60 = 24

An example of an equation that is a linear function explain why it is linear

tatuchka [14]

One example of a linear equation is
y = 7x + 4 because the slope is a set number and the graphed version of the equation is a completely straight line.
Hope this helps!
