Answer:

a = -u + k

Step-by-step explanation:

u = k - a

Let’s pretend k = 15 a = 4 and u = 11

11 = 15 - 4

a would be -11 + 15 which equals 4

What are the characteristics of the graph of the inequality x ≥ -2? The ray will move to the left. The ray will move to the righ

Alenkasestr [34]

Answer:

Step-by-step explanation:

The inequality x ≥ -2 is graphed on a number line. -2 is the smallest possible value. All subsequent values are larger and therefore lie to the right of -2.

Thus, the following are true:

1. The ray will move to the right (because x begins at -2 and increases, which means moving to the right on the number line).

2. It will use a closed circle (because x = -2 is part of the solution set).

Solve this system of linear equations. Separate the x- and y-values with a comma.

vodomira [7]

Answer:

x = $\frac{5}{2}$ , y = $\frac{5}{4}$

Step-by-step explanation:

1. Isolate for x in one of the equations:

2x = 9x - 14y

2x-9x = 9x-9x -14y

-7x = -14y

-7x/-7 = -14y/-7

x = 2y

2. Substitute 2y in for x in the second equation:

9(2y) = 40 - 14y

3. Simplify:

18y = 40 - 14y

4. Isolate for y:

18y+14y = 40 -14y+14y

32y = 40

32y/32 = 40/32

y = $\frac{5}{4}$

5. Substitute the new y-value into the simplified expression x = 2y:

x = 2(5/4)

x = $\frac{5}{2}$

hope this helps!
