The ordered pair (-1, 6) is the solution to the system of equations.

Step-by-step explanation:

Given equations are;

3x+2y=9 Eqn 1

y=4x+10 Eqn 2

Putting value of y from Eqn 2 in Eqn 1

$3x+2(4x+10)=9\\3x+8x+20=9\\11x=9-20\\11x=-11$

Dividing both sides by 11

$\frac{11x}{11}=\frac{-11}{11}\\x=-1$

Putting x=-1 in Eqn 2

$y=4(-1)+10\\y=-4+10\\y=6$

Solution: (-1, 6)

The ordered pair (-1, 6) is the solution to the system of equations.

Answer:

$y(x)=-0.028x+14.6$

Step-by-step explanation:

Birth Rate in 1994 = 14.6 births per thousand population.

Birth Rate in 2004 = 14.32 births per thousand population.

A linear equation is of the form: y=mx+c

Where:

x=years after 1994
y=the birth rate
m=Yearly Birth Rate

First, we determine the birth rate per year

$m=\dfrac{14.32-14.6}{10-0}\\=\dfrac{-0.28}{10}\\m=-0.028$

Therefore, a linear equation that relates y in terms of x is of the form:

$y(x)=-0.028x+c$

When x=0, y=14.6

14.6=-0.028(0)+c

c=14.6

Therefore, the linear equation that relates y in terms of x is:

$y(x)=-0.028x+14.6$

This is complicated- what is 3x + (-2x)?

allochka39001 [22]

3x + (-2x) would be just subtracting 2x from 3x, so it would be 1x or x. Hope this helped<3

Let's rewrite the mixed number as a fractions:

$\begin{gathered} 3\frac{2}{3}=\frac{11}{3} \\ 4\frac{1}{2}=\frac{9}{2} \end{gathered}$

Therefore, the total length will be:

$3\cdot(\frac{11}{3})+2(\frac{9}{2})+4=24ft$
