Answer:

A measures 72 and B measures 108

Step-by-step explanation:

If the angles are supplementary, that means that they add up to equal 180.  3x + 12 + 4x + 28 = 180.  Doing some algebra there gives you that 7x = 140 and x = 20.  Sub in 20 to angle A to get 3(20) + 12 = 72, and sub in 20 to angle B to get 4(20) + 28 = 108.  And of course, 108 + 72 = 180.

What is the perimeter of RSTUV?
MrMuchimi

Answer:

this should be 132 units   i hope this helps!   :)

Step-by-step explanation:

so these figures are similar

we are given 3 side measurements on one, and 3 on the other

we know that side BA is 10 units, and that SR which is the same side, is 14 units

we can conclude that they added 4 units to this side

so with the other side lengths that we are given we can figure out what the length of the perimeter of RSTUV is

10 + 4 = 14

15 + 4 = 19

28 - 4 = 24  

42 - 4 = 38

25 + 4 = 29

42 TU

28 UV

19 VR

14 SR

29 ST

add all the side together to get 132 units

Which statement is true of the function f(x) = -3/x? Select three options.
melamori03 [73]
<h2>Answer:</h2>

We have the following function:

f(x)=-\frac{3}{x}

The graph of this function has been plotted below. So lets analyze each statement:

<h3>1. The function is always increasing. </h3><h3>False</h3>

As you can see x increases from -∞ to 0 and decreases from 0 to +∞

<h3>2. The function has a domain of all real numbers. </h3><h3>False</h3>

The function is undefined for x=0 since x is in the denominator.

<h3>3. The function has a range of {yl- </h3>

Statement is unclear but the range is the set of all real numbers except zero.

<h3 /><h3>4. The function is a reflection of y = 3. </h3><h3>False</h3>

The function is a reflection in the x axis of the function g(x)=\frac{3}{x}

<h3>5. The function passes through the point (3,-27).</h3><h3>False</h3>

This is false since:

f(3)=-1\neq -27

Note. As you can see those statements are false, so any of them is true, except item 3 that is unclear.
