Y = k/x
13 = k/6
k = 78

y = k/x
8 = 78/x
8x = 78
x = 78/8
x = 9.75

Y = x - v/b ; solve for x
elena-s [515]

Answer:

x = y + v/b

Step-by-step explanation:

You can solve for x by adding v/b to both sides since that is what will isolate x the quickest and that is what you want to do when you need to solve for something.

By adding v/b to both sides, you will end up with x=y+v/b and that’s your answer!

Hope this helps!

Which equation represents a line that passes through the two points in the table x 1,5 and y 1,6
aleksandrvk [35]

For this case we must find a linear equation of the form:

y = mx + b

Where,

m: slope of the line

b: cutting point with vertical axis.

For the slope we have the following equation:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

Substituting values we have:

m = \frac {6-5} {1-1}\\m = \frac {1} {0}

We observe that the slope of the line is not defined.

Therefore, the line is vertical.

Thus, the equation of the line is given by:

x = 1

Answer:

The equation of the line is given by:

x = 1

9(3+5) is equivalent because factoring a 9 out of both 27 and 45 leaves us with 9(3+5).
