Answer:

\frac{114t}{v} =D

Step-by-step explanation:

It's all about algebraically manipulating the equation.  We want to get D by itself, so how do we do that?  Well, D is being multiplied by v and divided by 114, so we just need to do the opposite to both sides of the equation.  

You just multiply both sides by 114 and then divide both sides by v.  You could do it in either order since there is no addition or subtraction, if there was you would have to take that into consideration.

Simplify using the identity −2 /7 x 1/5 + 1/3 - 4/5 x - 2/7​
ElenaW [278]

Answer:

1/3 + 6/35

Step-by-step explanation:

We are given;

−2/7 × 1/5 + 1/3 - 4/5 × -2/7

Using the rule of bodmas, we will group them and solve with multiplication being the first operation.

1/3 - (4/5 × -2/7) + (−2/7 × 1/5)

Factorization of first and second bracket gives;

1/3 + 2/7(4/5) + 2/7(-1/5)

Factorizing again gives;

1/3 + 2/7(4/5 - 1/5)

>> 1/3 + 2/7(3/5)

>> 1/3 + 6/35

Write an equation in point-slope form that includes points (-1,4) and (2,-2)
amid [387]
First you have to find slope:
m = -2 - 4/2 - -1
m = -6/3
m = -2

Then plug any points into equation
y = mx + b to get b
-2 = 2(-2) + b
-2 = -4 +b
B = 2

So you're equation is:
y = -2x + 2
