translate, call the number, n

Eight more than (8+) twice a number increased by 3 (2(n+3)) is equal to (=) 79 (79)

8+2(n+3)=79

minus 8 both sides

2(n+3)=71

divide both sides by 2

n+3=35.5

minus 3 both sides

n=32.5

the number is 32.5

This problem can be interpreted different ways.

Here's how I interpret it:

Eight more than twice a number, increased by 3, is equal to 79. Find the number

Let n = the number

"Eight more": + 8

"Eight more than twice a number": 2n + 8

"Eight more than twice a number increased by 3": 2n + 8 + 3

"Eight more than twice a number increased by 3 is equal to 79.":

2n + 8 + 3 = 79

Now we solve the equation for n.

2n + 8 + 3 = 79

2n + 11 = 79

2n = 68

n = 34

The number is 34.

What is the equation of the line that passes through the point (-6, -8) and has a slope of 1/3

ivanzaharov [21]

Answer <u>(assuming it can be in point-slope form)</u>:

$y + 8 = \frac{1}{3} (x+6)$

Step-by-step explanation:

With the given information, we can use the point-slope formula, $y-y_1 = m (x-x_1)$ , to write the equation of the line. Substitute values for the $m$ , $x_1$ , and $y_1$ in the formula to do so.

The $m$ represents the slope, so substitute $\frac{1}{3}$ in its place. The $x_1$ and $y_1$ represent the x and y values of one point the line intersects, so substitute -6 for $x_1$ and -8 for $y_1$ . This gives the following answer and equation (just make sure to convert the double negatives into positives:
