Answer:

3r + 2s + 8t + 15

Step-by-step explanation:

7r + 10 - 2(2r + 3s - 5t) + 2(4s - t) + 5

=  > 7r + 10 - 4r - 6s + 10t + 8s   -  2t + 5

=  > 7r - 4r + 8s - 6s + 10t - 2t + 10 + 5

=  > 3r + 2s + 8t + 15

The graph of y2+3x=0 is symmetric with respect to which axis?
natta225 [31]

Answer:

The graph of y2+3x=0 is symmetric with respect to the x-axis

Step-by-step explanation:

To establish symmetry with respect to the x-axis we simply substitute -y in place of y in the original equation. If the resulting equation is identical to the original one then the function is said to be symmetric with respect to the x-axis.

In this case we have;

y^{2} +3x=0\\(-y)^{2} +3x=0\\y^{2} +3x=0

Which is identical to the original equation

What are the coordinates of point Q?
Lady bird [3.3K]

Answer:

Q (-4, -2); 2 units; Q' will be above the x-axis; 2 unites; no; yes, the y coordinates are multiplied by -1; Q' (-4, 2); R' (-2, 2), S' (1, 5), T' (-2, 5);

Step-by-step explanation:

even after a reflection over the x-axis, each points distance from the x-axis will stay the same

the x-coordinates don't change because the distance from the y-axis stays the same

the picture below shows points of Q'R'S'T', just connect the vertices

Researchers are investigating whether people who exercise with a training partner have a greater increase, on average, in target
bulgar [2K]

Answer:

1 - If method I is used, population of generalization will include all those people who may have varying exercising habits or routines.  They may or may not have a regular excersing habit.  In his case sample is taken from a more diverse population

2 - Population of generalization will include people who will have similar excersing routines and habits if method II is used since sample is choosen from a specific population

Step-by-step explanation:

Past excercising habits may affect the change in intensity to a targeted excersise in different manner. So in method I a greater diversity is included and result of excersing with or without a trainer will account for greater number of variables than method II.
