Answer: compare the relative strength of coefficients.

Step-by-step explanation: The Coefficient of determination usually denoted as R^2 is obtained by taking the squared value of the correlation Coefficient (R). It's value ranges from 0 to 1 and the value obtained gives the proportion of variation in the dependent variable which could be attributed to it's correlation or relationship to th independent variable. With a R^2 value close to 1, this means a large portion of Variation in a variable A could be explained due to changes in variable B while a low value signifies a low variance between the variables. Hence, the Coefficient of determination is used in comparing the relative strength of the Coefficients in other to establish whether a weak or strong relationship exist.

What is the answer for x,3x=5(m+3)-3
Ksenya-84 [330]

Answer:

x = \frac{5m}{3}+ 4

Step-by-step explanation:

3x = 5m +15 - 3

3x = 5m + 12

x = \frac{5m}{3} + \frac{12}{3} = \frac{5m}{3}+ 4

Andre runs for 35 seconds at a velocity of -8 meters per second. He is running west. What is his finishing position?
user100 [1]

Answer:

d = -280 m

Step-by-step explanation:

Given that,

Velocity of Andre, v = -8 m/s

Time taken, t = 35 seconds

We need to find his finishing position. Let the finishing position be x.

We know that,

Velocity = distance/time

So,

d=v\times t\\\\d=-8\times 35\\\\=-280\ m

so, he was at a distance of 280 m in west.

2x + 3y = 26<br> 3x + 5y = 40
vaieri [72.5K]

2x + 3y = 26 -- equation 1

3x + 5y =40 -- equation 2

(Equation 1) * 3

6x + 9y = 78 -- equation 3

(Equation 2) * 2

6x + 10y = 80 -- equation 4

(Equation 4) - (Equation 3)

y = 2 -- equation 5

(Equation 5)'s value of y into (Equation 1)

2x + 3(2) = 26

2x = 20

x = 10

Thus x = 10 and y = 2

Hope that helps!
