The triangle is Equilateral thus the sides are same and equal.

So ;

5x = 3x + 10

5x = 6x - 5

3x + 10 = 6x - 5

We just need to solve one the above equations and the value of x.

Then put in all three equations to find the sides .

Let's do it....

5x = 3x + 10

Subtract sides 3x

- 3x   + 5x =  - 3x + 3x + 10

Simplification

2x = 10

Divide sides by 2

(2)/(2) x =   (10)/(2)  \n

Simplification

x = 5

_________________________________

It's time to find the sides :

RS = 6(5) - 5

RS = 30 - 5

RS = 25

##############################

SQ = 3(5) + 10

SQ = 15 + 10

SQ = 25

##############################

RQ = 5(5)

RQ = 25

##############################

Actually we knew that the sides of any Equilateral triangle are same.

Find the equation of the perpendicular bisector of a line segment whose end points are (-3,9) and (-1,5)

Answers

First find the equation of y.

y=mx+n=(\Delta y)/(\Delta x)x+n

Find the slope m.

m=(5-9)/(-1-3)=(-4)/(-4)=1.

Pick one point, I'll pick (-3, 9). Insert coordinates in equation then compute n.

9=1(-3)+n\implies n=12.

The equation of a line y is:

y=x+12.

The perpendicular line y_(\perp) is same like the normal line except its slope m becomes:

k=-(1)/(m)=-1.

The equation of a perpendicular bisector is thus:

y_(\perp)=-x+12.

Hope this helps.

Answer:

y = (1)/(2) x + 3

Step-by-step explanation:

Using the given points, first find the slope:

m = (₂ - y₁) / (x₂ - x₁)

   = (5 - 9) / (-1 - (-3))

   = -4 / 2

    = -2

Find y-intercept by using anyone of the give points and slope from above:

y = mx + b

5 = -2(-1) + b

5 = 2 + b

b = 3

With the m and b, you can make equation of line:

y = mx + b

y = -2x + 3

To find the perpendicular slope, make it opposite and inverse it.

m = -2 becomes 1/2

Regular equation of line:

y = -2x + 3

Perpendicular equation of line:

y = (1)/(2) x + 3

how do I figure out the weight loss of tina? she lost 3 pounds on the first week of her diet. she gained a pound on the second week, and then lost 2 pounds a week during every week afterwards. she has been dieting for a total of 13 weeks. how many pounds has tina lost in all?

Answers

1st week - Lost 3 pounds = +3 
2nd week - Gained 1 pound = -1    
3+13 = + 22       

So 22+3 = 25                 25-1 = 24 

So Tina lost 24 pounds in 13 weeks.
