Answer:

y - y1 = m(x - x1)

Step-by-step explanation:

The point slope form equation is [ y - y1 = m(x - x1) ]

(x1, y1) is any given point on the line.

m is the slope.

To solve this you would need these things:

Slope (y2-y1/x2-x1)
Y-intercept (y = mx + b)

Best of Luck!

In 1960, the population of a town was 14 thousand people. Over the course of the next 50 years, the town grew at a rate of 30 pe

SOLUTIONS

Given: Assume y is the population

$\begin{gathered} t=0=1960,y=14030 \\ t=1=1961,y=14060 \\ so\text{ b = 14000} \\ so\text{ k = 30} \end{gathered}$

The town grow at the rate of 30 people per year.

$y=kt+14000$ $y=30t+14000$

(A) The population predicted to be in 2030 will be

$\begin{gathered} 2030-1960=70 \\ y=30k+14000 \\ y=30(70)+14000 \\ y=2100+14000 \\ y=16100people \end{gathered}$

(B) so when y = 15000, find t

$\begin{gathered} y=15000 \\ y=30t+14000 \\ 15000=30t+14000 \\ 15000-14000=30t \\ 1000=30t \\ t=\frac{1000}{30} \\ t\approx33 \\ t=1960+33 \\ t=1993 \end{gathered}$

What is the value of x?

musickatia [10]

X = 7. Because both lines equal the same so it has to equal 75
11 x 7 = 77
77-2 = 75
X = 7

Answer:

Step-by-step explanation:

We know: opposite angles in a parallelogram have the same measure.

Therefore we have the equation:

$x+y=87+y$ <em>subtract y from both sides</em>

$x=87$

We know: the sum of the angle measures in the triangle is 180°.

Therefore we have the equation:

$42+(x+y)+20=180$ <em>subtitute x = 87</em>

$42+87+y+20=180$

$149+y=180$ <em>subtract 149 from both sides</em>

$y=31$

5. Identify the slope and y-intercept of the line with the given equation.

xeze [42]

$
y=mx+b\\
m- \hbox{slope}\\
b- \hbox{y-intercept}\\\\
\underline{y=5x+2}\\
m=5\\
b=2\\\\
2x+y=-6\\
\underline{y=-2x-6}\\
m=-2\\
b=-6$
