Answer:
The equations are not compatible
Step-by-step explanation:
y = -4x + 3
8x + 2y = 8
substitute for y:
8x + 2(-4x + 3) = 8
simplify:
8x - 8x + 6 = 8
6 ≠ 8
Answer:
9)x=135º
10)x=2 23º
11)x=2 122º
Step-by-step explanation:
15x-7=19x-15
-4x=-8
4x=8
x=2
54x+14=43x+36
11x=22
x=2
Then y = 14.
___
The (x, y) values that satisfy both equations are (2, 14).
Answer:
9 zebra fish and 5 neon tetras. White
Answer:
(1). 8
(2). 8
(3). 8
(4). 8
Step-by-step explanation:
Statement (1).
The domain of this graph is [0, 10]
True.
(x-values or input values of the function is a set of values between 0 and 10 including 0 and 10 both)
Statement (2).
The Range of this graph is {3, 7, 9, 12}.
True.
(For input values x = 0, 4, 9, 10 there is a distinct output value y = 3, 7, 9, 10
Statement (3).
This graph represents continuous data.
True.
Since this graph has a distinct value of y for every value of x and the graph is not interrupted.
Therefore, it's a continuous function.
Statement (4).
The graph represents a function.
True.
For every value of x (input value ) a distinct value of y (output value) is obtained.
Therefore, graph represents a function.
