Answer:
Step-by-step explanation:
Please enclose the fractional coefficient inside parentheses: y= (1/2x) − 3 for greater clarity.
Make a table of ordered pairs:
x y = (1/2)x - 3
0 -3
1 (1/2)(1) - 3 = -2 1/2
3 (1/2)(3) - 3 = -3/2
The y-intercept is the point at which x = 0, and (from the table) is -3. Plot a dark dot at (0, -3).
Now graph (3, -3/2), leaving a dark dot.
Draw a line thrugh (0, -3) and (3, -3/2).
Answer:

Step-by-step explanation:
Solve by substitution. Solve the second equation for x:

Insert the value of x into the first equation:

Solve for y. Simplify multiplication using the distributive property:

Subtract 190 from both sides:

Isolate the variable to find its value. Divide both sides by -29:

Now take the value of y and insert back into either equation to solve for x:

Subtract 6 from both sides:

Divide both sides by 5:

Therefore, the solution to the system is
.

Answer:
w = 30
Step-by-step explanation:
50 = 10 * 5 therefore w is 6 * 5 = 30
6/10 = 30/50
Answer:
y= -3.6
Step-by-step explanation:
-9.5(1.4)-2.5y=-4.3
-13.3-2.5y=-4.3
-9=2.5y
y=-3.6
