Which is the best method for solving the system? and explain why it is the best
ololo11 [35]

Answer:

  b: elimination

Step-by-step explanation:

My vote is for elimination, though any of these methods (and some not listed) will get an answer quickly.

Subtracting the second equation from twice the first gives ...

  2(9x +8y) -(18x -15y) = 2(7) -(14)

  31y = 0 . . . simplify

  y = 0 . . . . . divide by 31 (or invoke the zero-product rule)

Then the value of x can be found from the first equation:

  9x = 7

  x = 7/9

__

I like this method because it tells you that y=0 in one step. (Graphing does the same.) For the numbers here, you can do it mentally. Once you recognize that the x-coefficients and the constants are related by the same factor, and that factor is different for the y-coefficients, it becomes apparent that elimination will immediately tell you that y=0.

Which of the following values are in the range of the function graphed below? Check all that apply. HELP PLEASE !!!!!
poizon [28]
The only answer is choice D) 6

Recall that the range is the set of possible y output values of a function. In other words, its the list of y coordinates for every point on the function curve. 

In this case, the horizontal line has EVERY point on it with a y coordinate of y=6. Two such points are (0,6) and (2,6). No other y value is possible. No matter what x value we plug in, the output is always y = 6

Side Note: the domain appears to be from x = -3 to x = 5

If mJK=(7x-39) and mML)=87, find x
lilavasa [31]
If two chords of a circle are congruent, then their intercepted arcs are congruent
7x-39 = 87
7x = 87 + 39
7x = 126
x = 126/7
x = 18

aylor and Natsumi are making block towers out of large and small blocks. They are stacking the blocks on top of each other in a
frozen [14]

Answer:

The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.

Step-by-step explanation:

This question is solved using a system of equations.

I am going to say that:

x i the height of a large block.

y is the height of a small block.

Taylor uses 4 large blocks and 2 small blocks to make a tower 63.8 inches tall.

This means that:

4x + 2y = 63.8

Simplifying by 2:

2x + y = 31.9

So

y = 31.9 - 2x

Natsumi uses 9 large blocks and 4 small blocks to make a tower 139.8 inches tall.

This means that:

9x + 4y = 139.8

Since y = 31.9 - 2x

9x + 4(31.9 - 2x) = 139.8

9x + 127.6 - 8x = 139.8

x = 12.1

y = 31.9 - 2x = 31.9 - 2(12.1) = 7.7

The height of a large block is of 12.1 inches and of a small block is of 7.7 inches.
