y = 3x - 1
x - y = -9
Subs y in second equation.
x - (3x - 1) = -9
x - 3x + 1 = -9
-2x = -9 - 1
-2x = -10
x = -10/-2
x = 5
Subs x
y = 3x - 1
y = 3.5 - 1
y = 15 - 1
y = 14
Step-by-step explanation:
y-13<6
y<6+13
y<19
hope it helps.

Answer:
Step-by-step explanation:
The key to solving this problem lies in understanding that the domain of the square root function includes ONLY zero or positive numbers.
In this case, we set 4x - 3 ≥ 0.
Solving for 4x: 4x ≥ 3. Therefore, x ≥ 3/4.
The domain of the given function is [3/4, ∞ ).
Answer:
probably it
Step-by-step explanation:
First, get the area of the rectangle then subtract the triangle, the result will be the shaded area:
area rec = 18 * 11
area rec = 198 cm²
small side of tri = 11 - 5
small side of tri = 6 cm
area tri = (height * width) / 2
area tri = (6 * 18) / 2
area tri = 108 / 2
area tri = 54 cm²
area shaded = 198 - 54
area shaded = 144 cm²
