Write an expression that represents n plus 7 multiplied by 3.
diamong [38]
The <span>expression that represents n plus 7 multiplied by 3 is
(n + 7)(3)
The entire expression, (n + 7) is multiplied by 3 since it would be inconvenient to state the expression as given above if what is meant was
(n + 7x3). It would have simply been n plus 21.</span>

Bamboo plants grow rapidly. A bamboo plant is 130 inches tall. Tomorrow it will be 143 inches tall, the next day it will be 156
tensa zangetsu [6.8K]
An arithmetic sequence has a common difference.
143 - 130 = 13
156 - 143 = 13
169 - 156 = 13
The common difference is 13.

a1 = 130
a2 = 130 + 13
a3 = 130 + 2 * 13
a4 = 130 + 3 * 13
...
an = 130 + (n - 1) * 13

an = 130 + 13(n - 1)

an = 130 + 13n - 13

an = 117 + 13n

an = 13n + 117

Find the equation of the line, where P is a point on the graph of the line.<br><br> m=2/3 , P(3,5)
Liula [17]

Answer:

The answer is

y =  \frac{2}{3} x + 3

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To write an equation of a line given a point and slope we have

y - y1 = m( x - x1)

where (x1 , y1 ) is the point and m is the slope

Equation of the line using point P(3 , 5) and m = 2/3 is

y - 5 =  \frac{2}{3} (x - 3)

y - 5 =  \frac{2}{3} x - 2

y =  \frac{2}{3} x + 5 - 2

We have the final answer as

y =  \frac{2}{3} x + 3

Hope this helps you
