Answer:
4x^2 - 28x
Step-by-step explanation:
area = length * width
a = 4x * (x-7)
4x^2 - 28x
360/9= 40
180-40= 140
140/2= 70
X=70
Answer:
1/10000
Step-by-step explanation:
10 ^ -4
a^ -b = 1/a^b
1 / 10^4
1/10000
Answer: 4/1
Step-by-step explanation:
Rise over run. Starting at 1 on the y axis this line moves up 4 and over (right) 1 before it hits 1 on the x axis.
Answer: C
Step-by-step explanation: For a function, each x-coordinate corresponds to exactly one y-coordinate.
To determine whether the graph shown here
is a function, we can use the vertical line test.
The vertical line test tells us that if each x-coordinate on the graph corresponds to exactly one y-coordinate, then any vertical line that we draw on the graph should hit the graph at only one point.
For the graph show here, any vertical line that you draw with hit the graph at only one point which means it does pass the vertical line test.
So this graph is a <em>function</em>.
