Answer:
Step-by-step explanation:
f(x) = (-2/3)x + 2 is clearer.
To find the x-intercept(s), set this function equal to zero and solve for x:
0 = (-2/3)x + 2, or (2/3)x = 2. Multiplying both sides by the reciprocal 3/2 of the slope 2/3, we get: x = (3/2)(2) = 3.
Thus, x = 3 when y = 0. This is the x-intercept: (3, 0)
To find the y-intercept(s), set x = 0 and find y: (-2/3)(x) + 2 = 2. Therefore, the y-intercept is (0, 2).
To graph this line, plot the x- and y-intercepts found above. Then connect these two points with a straight line.
Answer:
(-2, 3)
Step-by-step explanation:
For x-4 you go left four places and y+6 go up 6 places
Answer:
C) independent variable = age
dependent variable = reaction time in milliseconds
Step-by-step explanation:
The linear regression statistical test is best used for research experiment where there is a single dependent and one independent variable whjre both variables are numeric. In the given options above, the city of residence, gender, college major and political affiliation are all possible categorical variables and age, salary, miles driven and reaction time are all numerical variables. Hence, the best situation in which to use linear regression is a test where both the independent and dependent variables are either age, salary, reaction time or miles driven.
Answer:
5.5 or 5 1/2
Step-by-step explanation:
44 students ÷ 8 rows = 5.5
Part A you would just distribute your 3 to your X and your 5. After doing that you would get 3x+15+x=4x. Next you would combine like terms, meaning combine your x's together that is on the same side of your equal sign. So you would add 3x and x. When finished with that you would get, 4x+15=4x. You would then subtract your 4x on both sides of your equal sign. You then would get 15=0 which is no solution.
Part B you would distribute your 4 to your 1 and -x. After doing this your equation should then look like 4-4x=5x+8. Next you would try to get your like terms together. You would add 4x on both sides of your equal sign. Your equation should then look like 4=9x+8. Next you would subtract your 8 on both sides of the equal sign because your getting your terms together. Your equation should then look like, -4=9x. This answer would be one solution.
Part C you would combine your like terms, meaning add your 2x and x together to get your equation looking like, 3x+5=5+3x. You can tell just by looking at this equation it's going to be a infinite number of solutions.
Hope this helps! (:
