Answer:
-2
Step-by-step explanation:
Answer:
180=2x+ 24( angles opposite to equal sides)
156/2=x
x=78
Step-by-step explanation:
The graph of the function

is parabola with branches going down in the negative direction of y-axis.
The vertex of parabola has coordinates:

Then you can conclude that all x are possible, that means that the dimain is

and the maximum value of y is at the vertex, then the range is
![(-\infty,6]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C6%5D)
.The function is increasing for x<-2 and decreasing for x>-2 (since vertex is the maximum point).
When x=0, y=2.
Hence,
<span>The domain is {x|x ≤ –2} - false.
</span>
<span>The range is {y|y ≤ 6} - true.
</span>
<span>The function is increasing over the interval (–∞ , –2) - true.
</span>
<span>The function is decreasing over the interval (−4, ∞) - false.
</span>
<span>The function has a positive y-intercept - true.</span>
Answer:
Line DG is equal to 16
Step-by-step explanation:
We know that
In a parallelogram, opposite sides are congruent.
Line DG is congruent to line FE, so they must have sides of equal length.
4z-48=z
4z=z+48
3z=48
48/3=z
16=z
Now we know that the variable is 16 increments, so we sub the 16 in for z in line DG
4(16)-48
64-48=16
Line DG is equal to 16
