Erik and Nita are playing a game with numbers. In the game, they each think of a random number from zero to 20. If the difference between their two numbers is less than 10, then Erik wins. If the difference between their two numbers is greater than 10, then Nita wins. I pick Erik won and they asked,Use your previous answers to write an algebraic statement that represents all the ways your player will win. Be sure to define your variable

Answers

An algebraic statement that represents all the ways Eric will wins is $|x-y|<10$ , where $x$ be the number that Eric thinks and $y$ be the number that Nita thinks.

If the difference between their two numbers is less than $10$ , then Erik wins. If the difference between their two numbers is greater than $10$ , then Nita wins.

Let $x$ be the number that Eric thinks and $y$ be the number that Nita thinks.

For to Eric to win, the difference in the numbers should be less than $10$ .

That is, $x-y<10$ , for $x>y$ or $y-x<10$ , for $y>x$ .

Or $|x-y|<10$ .

The measure of W is 134°, the measure of Y is 46°, and the measure of Z is 134°.What is the measure of X?
a 40°
b 46°
c 134°
d 90°

Answers

The angles in any quadrilateral must add up to 360 degrees.
A trapezoid is a quadrilateral, because it has four sides.

$W+X+Y+Z=360 \n \n (134)+X+(46)+(134)=360 \n \n 314+X=360 \n \n X=46$

Angle X is (b) 46 degrees.

B. 46 because the measure of all of the angles in a quadrilateral is 360. If you add 134+46+134 it equals 314, and 360-314 is 46.

Which of the following correctly completes the square for the equation below?x^2+2x=19
a. (x+2)^2=20
b. (x+1)^2=23
c. (x+1)^2=20
d. (x+2)^2=23

Answers

Answer:

c. $(x+1)^2=20$

Step-by-step explanation:

Since, for getting a perfect square on the left side of a quadratic equation we follow the following steps,

Step 1 : Make 1 as the coefficient of $x^2$ .

Step 2 : Add both side the square of a number which is half of the x's coefficient.

Given equation,

$x^2+2x=19$ -----(1)

Here, the coefficient of $x^2$ is already one.

And, the middle term is 2,

Half of 2 is 1

Also, 1² = 1

Thus, add 1 on both sides of equation (1),

$x^2+2x+1 = 19 + 1$

$(x+1)^2 = 20$ ( Because (a+b)² = a² + 2ab + b² )

⇒ Option C is correct.

The answer is :

c. (x+1)²=20

To check:
(x+1)²=20 (a+b)²=a²+2ab+b²
x²+2x+1=20
x²+2x=20-1
x²+2x=19

Transversal t cuts parallel lines a and b as shown in the diagram. Which equation is necessarily true? a) m<1=m<2 b)m<4=m<6 c) m<3+m<5=90 degrees d)m<7=m<8

Answers

If the numbering of the angles is similar to this:
1 | 2
-----
3 | 4
5 | 6
----
7 | 8

Then none of the the choices are necessarily true.

The equations would have been:
1 = 4 = 5 = 8
2 = 3 = 6 = 7
3 + 5 = 4 + 6 = 180
