Answer:
D. The equations do not have the same solution because the second eqlition can never be obtained when multiplying the first
equation by any value
Step-by-step explanation:
-21=14 Equ(1)
6.1=-42 Equ(2)
Multiplying the first equation by -3 will give
-63= -42
Which is not equivalent to the second equation
Multiplying the first equation by 3, we have
-63=42
Not equivalent to the second equation
Multiplying both sides of the first equation by -4, we have
84=56
Not equivalent to the second equation
D. The equations do not have the same solution because the second eqlition can never be obtained when multiplying the first
equation by any value
Answer:
E IS THE CORRECT ANSWER
The R-squared is 0.64 and it means that the dependent value explains 64% of the independent value in the simple regression analysis
Step-by-step explanation:
R-Squared value is a very important indicator in a regression analysis.
What does it measure?
It measures how close to the line of best fit are the data points. How good the fitted line is can be indicated by the value of the r-squared.
The maximum value it can take is 1 and at this value, there is a direct and complete relationship between the independent variable x and the dependent variable y. The value 1 represents an 100% relationship between both parties.
The r-squared has a value of between 0 and 100%. The closer to 100, the better the model while the closer to 100, the more faulty the model is. In fact, a value of 0 indicates no relationship at all between the dependent and the independent variable.
With an R-squared value of 0.64, the regression model works above average to explain that the dependent variable explains 64% of the independent value in the simple regression analysis.
The measures of GX = 13
The measures of 
EX = 4z + 1 and XF = 2z + 7
Take EX and XF equal time each other and then solve for z and then you will get GX because EX = XF = GX are congruent.
EX = XF
<h3>What is congruent?</h3>
Two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
4z + 1 = 2z + 7
2z = 6
z = 3
As, EX = XF = GX
EX = 4(3) + 1
EX = 13
Therefore, GX = 13 ------ ( EX = XF = GX )
To find the angle ABX, divide the angle ABC by 2 you will get

Answer:
x = -14
Step-by-step explanation:
3 + x/2 = -4
Subtract 3 from both sides:
x/2 = -7
Multiply both sides by 2:
x = -14
To find the slope of a line given the coordinates of two points, you should use the formula, Slope=y2-y1/x2-x1.
To find the slope of a line which contains the coordinates (8,-3) and (-2,7), you should substitute them into the previous mention formula.
Slope=y2-y1/x2-x1
Slope=(7--3)/(-2-8)
Slope=(10)/(-10)
Slope=-1
The slope of the line which contains the coordinates (8,-3) and (-2,7) is -1 or in other words letter A from the given choices.
