Which graph represents a function with a rate of change of 0.5?

Graph 4

Step-by-step explanation:

We are given four graph of different rate. We need to choose graph whose rate is 0.5

Rate of graph is equal to slope.

Slope is change in y over change in x.

Here, slope is 0.5. It is positive value.

So, graph will start from bottom left to right top.

Out of four graph only two graph which has same property.

Graph 3 and Graph 4.

Now we find the rate of each graph.

Graph 3:

First we take two point from graph.

(0,-1) and (1,1)

Thus, Rate is 2

Graph 4:

Two points are (0,-1) and (2,0)

Thus, rate is 0.5

Hence, Graph 4 is correct whose rate 0.5

it is x equals 3   plese mark me really need it

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
