Answer:
5y + 15x = 25, 9x - y = -4
Step-by-step explanation:
The standard form is Ax + By = C. We can make this simple by first creating the slope intercept equations of both questions:
1. y = (-3/5)x + 5
2. y = 9x + 4
For the first one, we must first get rid of the denominator by multiplying everything by 5, so we get 5y = -15x + 25, and then you can add 3x to both sides to arrive at your first standard eqn, 5y + 15x = 25.
For the second, all you need to do is swap the y and the 4, subtracting both y and 4 from each side, arriving at 9x - y = -4
Answer:
x ≤ 63
Step-by-step explanation:
x/3-10 ≤ 11
Opposite of -10 is addition, 10+11= 21
Opposite of x/3 is multiplication 3, 21*3= 63
If the inequality symbol, is an x or equal to symbol, the dot will be closed.
Pick the number and put it at the center and then label the rest on the number line.
If the variable is on the left side of the inequality, you can use whichever way the "arrow" (the inequality symbol) is pointing to shade.
If it is w ≥ 0, then you would graph on the number line 0 and make the dot filled in, and graph in the direction going right (>)
