Step-by-step explanation:

We're basically trying to rearrange the equation to make everything equal x instead of y.

The biggest thing to note here is that x has to be positive. In order to make x positive, we need to switch the signs of everything in the equation.

So it'll go a little something like this:

y = x - 8

y - x = -8

-x = -y - 8

x = y + 8

Answer:

x = y + 8

Answer:

$\= x = 82$

$s = 9.64$

Step-by-step explanation:

From the question we are told that

The data is 87 91 86 82 72 91 60 77 80 79 83 96

Generally the point estimate for the mean is mathematically represented as

$\= x = \frac{\sum x_i }{n}$

=> $\= x = \frac{87 +91 + 86 + \cdots + 96}{12}$

=> $\= x = 82$

Generally the point estimate for the standard deviation is mathematically represented as

$s = \sqrt{\frac{ \sum ( x_i - \= x )^2 }{ n -1 } }$

=> $s = \sqrt{\frac{ ( 87 - 82 )^2 +( 91 - 82 )^2 + \cdots + ( 96 - 82 )^2 }{ 12 -1 } }$

=> $s = 9.64$

Suppose that triangle TUV is an isosceles with the base VU.

vekshin1

Set them equal to each other and solve
3x + 39 = 4x +34
-x=-5
X=5
Plug it in
3(5) + 39 = 54
4(5) +34 = 54
For the final angle ,
54 + 54 = 108
180-108 =72
The angle measures are 54,54, and 72

What is an equation of the line that passes through

lys-0071 [83]

Answer:

Step-by-step explanation:

For the perpendicular of an equation you need to flip the fraction and change the sign from positive to negative or if it's negative to positive. 3/2 is changed to -2/3 which when multiplied by -2 gives you 4/3 and 4/3+5/3 is equal to 3.
