Nope.
The angles A and B do not add to 180°. Rather angles A and C add to 180°, because the sum of the measures of the arcs they intercept is 360°.
.. (2x -7) +(x+4) = 180
.. 3x = 183
.. x = 61

Then ∠B = (2*61 +3)° = 125°

_____
∠A = (2*61 -7)° = 115°
∠C = (61+4)° = 65°
∠D = 180° -125° = 55°
so ABCD is NOT a trapezoid..

Solve equation for z
liraira [26]

Answer:

z = 7

Step-by-step explanation:

9z + 4 / 5 - 8 = 5.4


Add 8 to both sides.


9z + 4 / 5 = 13.4

Multiply 5 by both sides.


9z + 4 = 67


Subtract 4 from both sides.


9z = 63


Divide both sides by 9.


z = 7

Domain and Range: determine the domain and Range for each graph
bija089 [108]

Given:

The graph of a function.

To find:

The domain and range of the given graph.

Solution:

Domain is the set of x-values or input values.

From the given graph it is clear that, the graph is defined for the interval (-4,4).

But there is a closed circle at x = -4 and an open circle at x = 4. It means, -4 is included and 4 is not included in the solution set.

Domain: [-4,4)

Domain: -4\leq x

Range is the set of y-values or output values.

From the given graph it is clear that, the output values are lie in the interval (-3,4).

But there closed circle at x = -3 and x = 4. It means, -3 and 4 are is included in the set of output values.

Range: [-3,4]

Range: -3\leq y\leq 4

Therefore, domain is -4\leq x and range is -3\leq y\leq 4.
