4y+x=40
4y=40-x
y=10-1/4x (divide all by 4 to get y by itself)

y=-3+2/3
y=(-9+2)3 (distribution)
y=-7/3

A population numbers 15,500 and grows at 3.75% per year. Write an exponential model for the growth of this population.

krek1111 [17]

Answer: $f(x)=15500(1.0375)^x$

Step-by-step explanation:

The exponential model for growth is given by :-

$f(x)=A(1+r)^x$ , where A = initial value , r = growth rate (in decimal), x = time (in years).

Given: A= 15,500 r= 3.75% = 0.0375

The exponential model for the growth of this population will be :

$f(x)=15500(1+0.0375)^x\\\\\Rightarrow\ f(x)=15500(1.0375)^x$

hence, the required model: $f(x)=15500(1.0375)^x$

Solve the system of equations using substitution.

Lynna [10]

Answer:

(6,12)

Step-by-step explanation:

Substitute the value of y into y=2x:

x+6=2x

x=6

Substitute x into the equation of y=2x

y = 2*6 = 12

Delvig [45]

Answer:

13=x

Step-by-step explanation:

Side-spliting theorem

21/(x-4)=14/6

cross multiply

21*6=14*(x-4)

distribute 14

126=14x-56

add 56 to both sides

126+56=14x-56+56

leaving you with

182=14x

Divide both sides by 14 to get x by itself

182/14=14x/14

13=x
