Answer:

Step-by-step explanation:

All triangle must have angle values adding up to 180 degrees.First solve for y;

110+33+y=180

y=37 degrees

x is the opposite inverse angle of 33 degrees, it has an angle measure of 33 degrees.

z is equal to 110 degrees because it is opposite to that angle measure because all rhombi have 2 way symmetry.

Answer: x = 33

y = 37

z = 110

Step-by-step explanation:

Recall: The sum of angles in a triangle is 180 , to get y , we have

180 - ( 33 +110)

= 180 - 143

= 37

Since we have parallel lines in the shape , z = 110

x = 180 - ( 110 + 37)

= 33

Karen is writing a word problem that can be represented by the equation 3+ 2 = 20.A box weighs 3 pounds and several 2 pound book

saul85 [17]

Her equation doesn't fit the word problem! It says several 2 pounds books but she put it as if there was one. She should have wrote the equation like this:
3 + 2x = 20 (where x represents the unknown amount of boxes)
and than you can just solve for x to find how many books there are
3 + 2x = 20
2x = 20
x = 10
So there are 10 books!

I hope that helps! Let me know if you have any questions :3

Answer:

The origin is (0,0) and to plot the points go over on the sideways line (right for positive numbers and left for negative numbers). Crawl over the sideways line and up the up and down line. For negative numbers on the up and down line go down, but for positive go up.

Write the partial fraction decomposition fro the ration expression below

zlopas [31]

$\dfrac{5x-2}{(x-1)^2}=\dfrac a{x-1}+\dfrac b{(x-1)^2}$
$5x-2=a(x-1)+b$

Since $5x-2=5x-5+3=5(x-1)+3$ , it follows that $a=5$ and $b=3$ , so

$\dfrac{5x-2}{(x-1)^2}=\dfrac5{x-1}+\dfrac3{(x-1)^2}$

$\dfrac{x^3+x^2+x+2}{x^4+x^2}=\dfrac{x^3+x+x+2}{x^2(x^2+1)}=\dfrac ax+\dfrac b{x^2}+\dfrac{cx+d}{x^2+1}$
$x^3+x^2+x+2=ax(x^2+1)+b(x^2+1)+(cx+d)x^2$
$x^3+x^2+x+2=(a+c)x^3+(b+d)x^2+ax+b$

When $x=0$ , you find that $b=2$ . It's also clear that $a=1$ . So the remaining constants must be $1+c=1\implies c=0$ and $2+d=1\implies d=-1$ , and so you get

$\dfrac{x^3+x^2+x+2}{x^4+x^2}=\dfrac1x+\dfrac2{x^2}-\dfrac1{x^2+1}$

PLS HELP ASAP ILL GIVE BRAINLKEST PLS THANKS

Andreas93 [3]

Answer:

y = 3x

Step-by-step explanation:

When y = 12, x = 4

When y = 0, x = 0

The y intercept is zero.

The easiest point to see clearly is (4,12)

m = y / x because the y intercept is 0

m = 12/4 = 3

The equation of the line is

y = 3x which is the last one.
