B. 9x²-6y²+3x
C. 9x²-12y²+3x
D. 9x²-12y²-11x

Answers

Answer:

$\sf D. 9x^2-12y^2-11x$

Step-by-step explanation:

$\sf (8x^2-9y^2-4x)+(x^2-3y^2-7x)$

Distribute the negative sign in the first set of parentheses:

$\sf 8x^2 - 9y^2 - 4x + x^2- 3y^2 - 7x$

Combine the terms that are alike:

$\sf 8x^2 +x^2-9y^2-3y^2-4x -7x$

$\sf 9x^2-12y^2-11x$

Therefore, the sum of the polynomials is:

$\sf D. 9x^2-12y^2-11x$

U can begin by simplifying the terms within each set of parentheses first and then combining like terms.

(8x² - 9x² - 4x) + (x² - 3y² - 7x)

= (-x² - 4x) + (x² - 3y² - 7x)

= -x² + x² - 4x - 7x - 3y²

= -11x - 3y²

Therefore, the sum of the polynomials is -11x - 3y², which is option D.

Which of the following equations are equivalent to-2m-5m-8 #-(-7) + m?D-15m-4md:7m-8-rn-4□-3m-8-4-m□m-4.7m-8-8.7m- 4-m□-8.3m-4-m

Answers

-2m - 5m - 8 = 3 + (-7) + m
-7m - 8 = 3 - 7 + m
-7m - 8 = m - 4 <=== here is one

m - 4 = -7m - 8 <=== another one
-8 - 7m = -4 + m <== and another one

Kari and Julie are practicing for basketball tryouts. Kari makes 3 less than twice as many baskets as Julie. Write an expression with two terms for the number of baskets that Kari makes. Explain how you found your expression

Answers

Answer:

X= 2y - 3

Step-by-step explanation:

Kari makes X tryouts. She also makes 3 less than twice as many as Julie which would be X= 2y - 3

Julie makes y tryouts and twice would be 2y.

1 minus 9 over 13 is?

Answers

1- 9/13
Steps:
1. Change 1 into 13/13 since 13/13=1 and this will give you a common denominator
2. New problem is 13/13 - 9/13
3. Do 13-9= 4
4. Your answer is 4/13 or .307

Word problem in Algebra - Two boys, Shawn and Curtis, went for a walk, Shawn began walking 20 seconds earlier than Curtis. Shawn walked at a speed of 5 feet per second. Curtis walked at a speed of 6 feet per second. For How many seconds had Shawn been walking at the moment when the two boys had walked the same distance?

Answers

So first you should simplify it.
Shawn (S) - 5 ft. per sec
Curtis (C) - 6 ft. per sec
1 sec 2 s   3 s 4s 5s 6s
S 25 ft   30 ft 35 ft 40 ft 45 ft 50 ft
C 6 ft 12 ft 18 ft    24 ft 30 ft 36 ft
So we keep going on with this table until we find two numbers that match, which is 30. Then we look back at the question. We want to find how many seconds Shawn was at when the hit the same distance as Curtis (30 ft). Yet be sure to keep in mind that Shawn started 20 seconds earlier. So the answer is 2 seconds.
