Answer:
B. f(x) = 5x - 7
Step-by-step explanation:
✔️Using the table of values given, find the slope (m) and y-intercept (b) of the line of the graph that represents the table, then write the function in slope-intercept form.
✔️Slope (m) using (0, -7) and (2, 3):
Slope (m) = ∆y/∆x
Slope (m) = (3 -(-7))/(2 - 0)
Slope (m) = 10/2
Slope (m) = 5
✔️ y-intercept (b):
b = -7, because where x = 0, y = -7, which is the point where the y-axis is intercepted by the line of the graph.
✔️Write the linear function in slope-intercept form by substituting m = 5 and b = -7 into f(x) = mx + b
Thus:
f(x) = 5x + (-7)
f(x) = 5x - 7
Therefore, the linear function that has a graph that includes all the points in the table would be f(x) = 5x - 7.
Answer:
Your answer will be x=2
Step-by-step explanation:
Five plus 6 times a number is equal to 21 minus 2 times the number
Your equation is this:
5+6x=21-2x
Subtract 6x from both sides
5+6x-6x=21-2x-6x
5=21-8x
subtract 21 on both sides
5-21=21-21-8x
-16=-8x Divide -8 on both sides
2=x
Hope this helps :)
False. For every x in the function's domain, f(x) describes the one single output.
10 ???? im Guessing.. Hope Its Right (: pretty sure it is ..
