For the graph's y-intercept, you can easily tell where the y-intercept is by looking at where it crosses the y-axis.

For the graph's slope, you can do rise over run (using two points).

For the table, the y-intercept is when x is 0. If there is not a point that has an x-coordinate of 0, you can find the change between the other points and work backwards.

For the table, the slope can be found using the slope formula and two points.

Slope Formula

(y2-y1)/(x2-x1)

Once you have found these values, you can easily compare the two.

In AABC, what is the value of x?
Dennis_Churaev [7]

Answer:

x = 6.5

Step-by-step explanation:

* since it's a triangle ALL the angles inside should give you 180° * Equate everything to 180°

8x + 10x - 10°+ 10x + 8° = 180°( sum of angles on a triangle)

28x - 2° = 180° * group like terms*

28x = 182°

x = 6.5

PLEASE HELP!!!!!

Part A: Yes this is a function because there are no repeated x values. Each x value points to exactly one y output. You can graph each point and the graph will not fail the vertical line test.

<span>----------------------------------------------</span>

Part B: Plug x = 6 into the f(x) function given to get
f(x) = 7x-15
f(6) = 7*6-15
f(6) = 42-15
f(6) = 27
Now compare this with the table. According to the table, when x = 6, the value of y is 14. So the f(x) value is larger than the table value when x = 6

----------------------------------------------

Part C:

Replace f(x) with 6 and solve for x

f(x) = 7x-15
6 = 7x-15
6+15 = 7x-15+15
21 = 7x
7x = 21
7x/7 = 21/7
x = 3

So the final answer, for part C, is x = 3
