Answer: It’s the third answer.
Step-by-step explanation:
There are 2.54 cm in one inch and 12 inches in one foot, so 2.54x12 = 1 foot. Multiply this by 2 to get 2 feet.
Answer:
Part A -> Function
Part B -> Function
Step-by-step explanation:
<u>Concept</u>
A relationship is a function only if there's a single y value corresponding to an x value. It can have the same y value for different x values but it <em>must not have multiply y values for a single x value</em>.
Below is an example
<u>Function</u> <u>Not a Function</u>
<u>x</u> <u>y</u> <u>x</u> <u>y</u>
1 5 1 5
2 6 2 7
3 5 1 6
<u>Part A</u>
Looking at the given graph, we see that the relationship has a single y value corresponding to an x value and so it is a function.
<u>Part B</u>
If there was the same number of bacteria for two consecutive hours it would mean the same y value for different x values. So, it would still remain a function.
Since the equation is in y = mx+b form you can easily determine the y intercept based on the b value present.
Y = mx + b
Y = 2x - 3
B = y intercept = (0,-3).
2x + 8y = 5
2/ 24x - 4y = -15
2x + 8y = 5
48x - 8x = -30
+
--------------------------
50x = -25
x = -1/2
2 * -1/2 + 8y = 5
-1 + 8y = 5
8y = 6
y = 6/8
y = 3/4
x = -1/2 y = 3/4
Answer:
y = x + 2
Step-by-step explanation:
The slope is 1
The y-intercept is 2
