(2,1), (4,2), (6,3) or (8,4) are the numbers we will use to find the first differences which will give us the unit rate
2/1 = 2
4/2= 2
6/3= 2
8/4= 2
therefore this graph is linear and its unit rate is 2.
Answer: The axis of symmetry is x = 0
This is basically saying that the axis of symmetry is the vertical y axis
The vertex is either the highest point or the lowest point on the parabola, depending on what the value of 'a' is. If the vertex is the y intercept, then the vertex is on the y axis. The axis of symmetry goes through the vertex.
Answer:
To find this out, we first need to see the change, is it a positive change or a negative change? Well in this case, as the temperature is increasing, we find that the change is positive. The next step we need to do, id that, how much was the change by, we can find this out by finding the absolute value of the difference of -16°F and 7°F
The absolute value means, the operations answer has to be positive, if not then it will become positive.
|-16°F -7°F|
=> |-23°F|
=> 23°F
If my answer helped, kindly mark me as the brainliest!!
Thank You!!
Answer:
12
Step-by-step explanation:
Put in 3 for x and 3 for y:
3(3 + 3 - 2)
3(4)
