Which expression represents the sum of (2x-5y) and (x+y)?
trasher [3.6K]
(2x-5y) + (x+y)  
= (2x+x) + (-5y+y)
 = 3x + (-4y)
 = 3x-4y 
 So option A is the correct one.

Answer this question!!!!!!!​
Vesnalui [34]

The expression can represent the value of x in terms of R, m, n and k after rearranging.

<h3>What is an expression?</h3>

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

The expression is:

\rm R = 4m\sqrt{\dfrac{xn}{k^3}}

Square both side:

\rm R^2 = 16m^2{\dfrac{xn}{k^3}}

16m² x n = R²k³

x = (R²k³)/(16m²n)

The above expression represents the value of x in terms of R, m, n and k.

Thus, the expression can represent the value of x in terms of R, m, n and k after rearranging.

Using 50 observations, the following regression output is obtained from estimating y = β0 + β1x + β2d1 + β3d2 + ε. Coefficients
pickupchik [31]

Answer:

The answer is "789.03 and 806.16".

Step-by-step explanation:

y\^ \ \ = -0.45 + 3.78(x)  -11.88(d_1) + 5.25(d_2)

For point a:

Calculating the value for y\^  \ \  x = 212,\ \  d_1 = 1, and  \ \ d_2 = 0

y\^  = -0.45 + 3.78(212)  -11.88(1) + 5.25(0)

     = -0.45 + 801.36 -11.88 + 0\\\\= 789.03  

For point b:

Calculating the value of y\^ \ \ for \ \ x = 212, \ \ d_1 = 0, and \ \ d_2 = 1

y\^  = -0.45 + 3.78(212)  -11.88(0) + 5.25(1)  

    = -0.45 + 801.36 -0 + 5.25\\\\= 806.16
