The system:
y = 3 x - 7
15 x - 5 y = 14
---------------------
Using the substitution method:
15 x - 5 · ( 3 x - 7 ) = 14
15 x - 15 x + 35 = 14
0 · x = 14 - 35
0 · x = - 21
x , y ∈ ∅
Answer:
D ) There is no solution.
Answer:
y=3/4x−12.
Step-by-step explanation:
Slope of the perpendicular line is negative inverse: m=34.
The equation of the perpendicular line is y=3x4+a.
To find a, we use the fact that the line should pass through the given point: −12=(34)⋅(0)+a.
a=−12.
Therefore, the equation of the line is y=3x4−12.

Answer: C
Step-by-step explanation:
Less than or more than without "or equal" means that the dot is not shaded, otherwise it is.
So the answer is C
Answer:
Domain: all real numbers
Range: all real numbers greater than or equal to -2
Step-by-step explanation:
The domain is the set of x-coordinates.
It is the set of real numbers since x can be any real number.
The range is the set of y-coordinates.
The minimum value for y is -2. y can be -2 or any real number greater than -2.
Answer:
Domain: all real numbers
Range: all real numbers greater than or equal to -2
