The\ domain:\\v+10\neq0\ \wedge\ v+6\neq0\\v\neq-10\ \wedge\ v\neq-6\\\\\dfrac{4}{v+10}=\dfrac{6}{v+6}\ \ \ \ \ |\text{cross multiply}\\\\4(v+6)=6(v+10)\ \ \ \ |\text{use distributive property}\\\\(4)(v)+(4)(6)=(6)(v)+(6)(10)\\\\4v+24=6v+60\ \ \ \ \ |\text{subtract 24 from both sides}\\\\4v=6v+36\ \ \ \ |\text{subtract 6v from both sides}\\\\-2v=36\ \ \ \ |\text{divide both sides by (-2)}\\\\\boxed{v=-18}\in D

Solve the following <br><br> 4x-1÷2=X+7
olga nikolaevna [1]

Answer:

x=5/2

Step-by-step explanation:

4x-1/2=x+7

4x=x+7.5

3x=15/2

x=5/2

with parentheses (in case u wrote it wrong)

(4x-1)/2=x+7

4x-1=2x+14

2x=15

x=7.5

Help? Please?<br> I really suck at geometry
Maslowich

Answer:

x = 14

y = 4

Explanation:

Ok so, just from looking at the two triangles i can tell they're congruent right triangles. I used different colors to show which sides of the triangle correspond and are equal to each other in my attatched photo.

So the side thats equal to x is the same length as the side that's equal to y+10 on the other triangle.

So we can write the equation x = y + 10.

Using this same method, the side that's equal to x + 2 is the same length as the side that's equal to 4y on the other triangle.

So, we can write the equation 4y = x + 2.

Now we have the equations \left \{ {{x=y+10} \atop {4y=x+2}} \right. you could rewrite to be in slope- intercept form so they're easier to graph. But a graphing calculator online would plot it just fine.

If you graph these two equations they'll intersect at the solution ( 14, 4 ). I'll include the graph in my images as well.

To check your answer, you can plug in x and y and see if the triangle sides end up being the same length. I did and it was correct.
