Answer:

D. x= 28, 2=23; Use corresponding and supplementary angles.

Step-by-step explanation:

The degrees of (5y-4)° and 3y° both (added together) sum up to 180 degrees.

So the equation would be: (5y-4)+3y= 180.

Step 1- Add common variables.

(5y+3y)-4= 180

8y-4= 180

Step 2- Add 4 to both sides.

8y-4= 180

<u>    +4    +4</u>

8y= 184

Step 3- Divide both sides by 8.

<u>8y</u>= <u>184</u>

8     8

y= 23

Now that we know what the variable y equals to, we can now solve for x. The equation would be: 3y=(2x+13).

Step 1- Substitute the known variable.

3(23)=2x+13

69= 2x+13

Step 2- Subtract 13 to both sides.

69= 2x+13

<u>-13         -13</u>

56= 2x

Step 3- Divide both sides by 2.

<u>56</u>= <u>2x</u>

2     2

x= 28

Hope this helps! :)

Describe the transformation required to obtain the graph of the given function from the basic trigonometric graph.
mamaluj [8]

Answer:

Option c. Reflection across the x-axis and vertical stretch by a factor of 7

Step-by-step explanation:

If the graph of the function y = cf(x) represents the transformations made to the graph of y = f(x) then, by definition:

If 0 then the graph is compressed vertically by a factor a.

If |c| > 1 then the graph is stretched vertically by a factor a.

If c then the graph is reflected on the x axis.

In this problem we have the function y = -7secx and our paretn function is y = secx

therefore it is true that

c = -7\\\\|-7|> 1\\\\-7.

Therefore the graph of y = secx is stretched vertically by a factor of 7 and is reflected on the x-axis

Finally the answer is Option c

In certain county, the number of charter schools is 4 less than twice the numbervof alternative schools. We know that there are
Vitek1552 [10]
1. Let's call the number of carter school: "x" and "y" the number of alternative school.  Then, you have that:

 - T<span>he number of charter schools is 4 less than twice the number of alternative schools.
</span> - T<span>here are 48 charter schools in the country.

 2. So, you have:

 x=2y-4  (i)

 x=48  (ii)

 3. Then, when you substitute x=48 into the equation (i), you obtain:
</span>
 x=2y-4
<span> 48=2y-4

 4. Now, you must clear "y, as below:

 48+4=2y
 2y=52
 y=52/2
 y=26
 </span><span>
 How many alternative schools are in the county?
</span><span>
 The answer is: There are 26 alternative schools.</span>
