Find the values of x and y.

a. x=44, y=66
b. x=46, y=44
c. x=90, y=44
d. x=90, y=46

Answers

m<B = m<C = 46
m<BAC = 180 - 2(46) = 180 - 88
y = 88/2 = 44

x = 180 - (44+46) = 180 - 90 = 90

-2, 0, 2, 12, 15, 15
median is the middle number
so
median = (2+12)/2 = 14/2 = 7

hope it helps
To find the median, you have to number it from smallest to largest. 
-2,0,2,12,15,15
Since there are 2 medians, you find the average of those two numbers.
2+12 is 14/2 is 7.
7 is the median.

Write an equation that represents a vertical translation 7 units down of the graph of g(x)=|x|

Answers

Translation involves changing the position of a function.

The equation that represents the new function is: [tex]\mathbf{g'(x) = |x| - 7}[/tex]

The parent function is given as:

[tex]\mathbf{g(x) = |x|}[/tex]

The rule of translating a function down is:

[tex]\mathbf{(x,y) \to (x,y-h)}[/tex]

Where: h is  the number of units translated down

i.e. h = 7

So, we have:

[tex]\mathbf{g'(x) = g(x) - h}[/tex]

Substitute [tex]\mathbf{g(x) = |x|}[/tex]

[tex]\mathbf{g'(x) = |x| - h}[/tex]

Substitute 7 for h

[tex]\mathbf{g'(x) = |x| - 7}[/tex]

Hence, the required function is: [tex]\mathbf{g'(x) = |x| - 7}[/tex]

The equation that represents the given situation is g(x) = |x|-7

To write an equation that represents a vertical translation 7 units down of the graph of g(x) = |x|, we need to modify the original function accordingly.

A vertical translation can be represented by adding or subtracting a constant to the function. In this case, since we are translating the graph downward by 7 units, we subtract 7 from the original function:

g(x) = |x| - 7

Thus, the equation that represents this vertical translation is g(x) = |x| - 7.

This results in each point on the graph of g(x) = |x| shifting 7 units downward, creating the new graph of g(x) = |x| - 7.

What is the area of the trapezoid shown? (1) angle a = 120 degrees (2) the perimeter of trapezoid abcd = 36?

Answers

Not enough information to solve this
Final answer:

Neither statement alone is sufficient to determine the area of the trapezoid.

Explanation:

The area of a trapezoid can be found using the formula:

Area = (1/2) * (sum of parallel sides) * height

To find the area of the trapezoid, we need the lengths of the parallel sides and the height.

(1) The given angle does not provide information about the lengths of the sides, so it is not sufficient to find the area.

(2) The perimeter of the trapezoid does not directly give information about the lengths of the sides, so it is also not sufficient to find the area.

Therefore, neither statement alone is sufficient to determine the area of the trapezoid.

how can i turn 7/2 into a decimal

Answers

We can split it into two numbers : 6 and 1

half of 6 is 3 as you need 2 lots of 3 to make six
half of 1 is 0.5 as you need 2 lots of 0.5 to make 1

therefore 3 + 0.5 is 3.5.

you need 2 lots of 3.5 to make 7
One method would be to get the denominator into a more common form for dealing with decimal values. Notice the root dec- , the Latin root for "10" in the word decimal. This describes the fact that our common number system, the decimal system, is based on powers of 10. To prepare 7/2 for conversion to decimal, we should first make sure its denominator is some power of 10. To make the conversion, let's multiply it by 1 in the form of 5/5:

[tex] \frac{7}{2} \cdot \frac{5}{5} = \frac{35}{10} [/tex]

Or, as a mixed number:

[tex]3 \frac{5}{10} [/tex]

If you're familiar with how to read decimal values, "3 and 5 tenths" can be written in decimal form as 3.5.
