2y^2 + 30xy - 2y^2 + 4y - 4x

Answers

you're gonna have 2y^2 - 2y^2 which cancel out giving you 0 so they dont go into the simplified answer. then, since 30xy is the only one that doesnt have a match you place that down. then place +4y , and then -4x . It will give you 30xy +4y -4x .

or vise versa with the 4y and 4x . whichever your answer choices are or how u prefer to write it. <3

Austin correctly answered 92% of the questions on a geography quiz. Liz answered 47 of the 50 questions correctly. Which student got the most questions correctly.
(if you answer this may you please show your work)

Answers

Answer: Liz
To find the percent Liz got correct, you would do 47/50 to get 0.94. You would then move the decimal 2 places to get 94%.
94%>92%

Answer:liz scored better

Step-by-step explanation:

Liz scored better because how to find a percentage is dividing whatever two numbers you have by each other so it would be 47 / 50 which equals 0.94 then you times it by 100. Which would equal 94% which is better than a 92 which means Liz got the higher score

-4 + -6 = -10

Step-by-step explanation:

you just have to start at the negative four and count up to the number negative ten, then you think “how many spaces are there between four and ten? SIX. so you just take six and turn it negative, boom.

Answer:

-4 + -6 = -10.

Step-by-step explanation:

let's think of it with positive numbers, you'd get 4+6=10. now turn them into negative numbers, now you're still adding, but you're getting a lesser number. the only way this happens is when you add negative (or MINUS) numbers.

The point (5, -1) is reflected over the
x-axis. What are the new coordinates?
A. (-5, 1)
B. (-5, -1)
C. (5, 1)
D. (-1,5)

Answers

Answer:

c

Step-by-step explanation:

when reflected across the x-axis the x becomes  negative and vise versa

when reflected across the y axis the y becomes negative and vise versa  

The new coordinates will be  [tex](5,1)[/tex] .

What are coordinates ?

Coordinates determine the position of the points or other geometric elements on graph.

We have,

Point [tex](5, -1)[/tex].

Reflected over x-axis,

So,

If a point [tex]( x,y)[/tex] under a reflection on the x-axis will be [tex](x,-y)[/tex] .

So,

according to the above mentioned statement,

Point [tex](5, -1)[/tex] reflected on the x-axis

We get ,

Reflected point [tex](5,1)[/tex] .

So, the new coordinates are  [tex](5,1)[/tex] .

Hence, we can say that the new coordinates will be  [tex](5,1)[/tex] .
