What is the midpoint of the segment joining (12,2) and (-5,-7)

Answers

Answer 1
Answer: To find midpoint the fomula is
x1+x2/2,y1+y2/2

so the answere would be 12+(-5)/2 , 2+(-7)/2

so mid point would be (x,y) =(3.5,-2.5)

I hope this makes sense :)

How to simplify 75/100

Answers

See what number go into both 75 and 100.
25 goes into both as 3*25 for 75
and 4*25 for 100
So to simplify it we take those two numbers and make another fraction
3/4
You can simplify it by dividing both numerator and denominator by 25 what will give us 3/4 (because 75 ÷ 25 = 3 and 100 ÷ 25 = 4).

I hope it will help you :)

What is the difference of the polynomials?(5x3 + 4x2) – (6x2 – 2x – 9)

A. –x3 + 6x2 + 9
B. –x3 + 2x2 – 9
C. 5x3 – 2x2 – 2x – 9
D. 5x3 – 2x2 + 2x + 9

Answers

(5x³ + 4x²) - (6x² - 2x - 9)

-1(6x²) -1(-2x) -1(-9) = -6x² + 2x + 9

5x³ + 4x² - 6x² + 2x + 9

5x³ - 2x² + 2x + 9  Choice D.


The difference between the polynomials (5x³-4x²)-(6x²-2x-9) is 5x³-2x²+2x+9 and the right option is D. 5x³-2x²+2x+9.

What is polynomial?

A polynomial is an expression of more than two algebraic terms

To calculate the difference between both polynomials we apply the techniques below.

Given:

  • (5x³-4x²)-(6x²-2x-9)

Substrat each like term accordingly.

  • (5x³-0)+(4x²-6x²)+(0-2x)+(0-9)
  • 5x³-2x²+2x+9

Hence, the difference between the polynomials (5x³-4x²)-(6x²-2x-9) is 5x³-2x²+2x+9 and the right option is D. 5x³-2x²+2x+9.
