What is the equation of the line that has a slope of 3 and goes through point (4, 7)?

1 answer:

3 0

<span>The slope of the line is equal to (y - 7) / (x - 4)
Then we can set up this equation:
(y - 7) / (x - 4) = 3
y - 7 = 3 * (x - 4)
y - 7 = 3x - 12
y = 3x - 5
This is the equation of the line.</span>

Any of these questions please

maw [93]

Answer:

See the explanation below.

Step-by-step explanation:

$f(t)=21020\left(1+0.012\right)^t\\\\f(t)=21020\left(1.012\right)^t\\$

Starting from $t=2002$

By putting $t=2015-2002=13$ we have:

$f(t)=21020\left(1.012\right)^{13}\\\\\approx 24546$

The perimeter of a stop sign is 99.2 inches. Each side of the stop sign is equal.

san4es73 [151]

Answer: The equation can be written as 8n = 99.2.

Step-by-step explanation:

In my answer, I used the variable n to distinguish itself as one side of the stop sign. 99.2 is the final perimeter in inches.

A stop sign is an octagonal shape (otherwise, it is made up of 8 equal sides). Therefore, with this information, you can interpret that the length of one side would be equal to the length of all of the other sides.

Hence, the answer can be represented as 8n = 99.2.
