Simplify the following expression (38x +61y) - (3x-11y)

Mathematics
1 answer:
aliina [53]4 years ago
5 0

Answer:

72 y + 35 x

Step-by-step explanation:

Simplify the following:

(61 y + 38 x) - (-11 y + 3 x)

-(-11 y + 3 x) = 11 y - 3 x:

38 x + 61 y + 11 y - 3 x

Grouping like terms, 61 y + 11 y + 38 x - 3 x = (61 y + 11 y) + (38 x - 3 x):

(61 y + 11 y) + (38 x - 3 x)

61 y + 11 y = 72 y:

72 y + (38 x - 3 x)

38 x - 3 x = 35 x:

Answer: 72 y + 35 x

Which equation represents a circle that contains the point (–5, –3) and has a center at (–2, 1)?
melisa1 [442]

Answer:

(x + 2)² + (y - 1)² = 25

Step-by-step explanation:

radius: r² = (1 - (-3))² + (-2 - (-5))² = 16 + 9 = 25

r = 5

Circle: (x - h)² + (y - k)² = r²

center: (-2 , 1)      h = -2       k = 1

(x + 2)² + (y - 1)² = 25

Which fraction is equivalent to StartFraction 2 Over 6 EndFraction? StartFraction 3 Over 7 EndFraction, because StartFraction 2
irinina [24]

Question:

Which fraction is equivalent to \frac{2}{6}?

- \frac{3}{7} because \frac{2}{6}= \frac{2 + 1}{6 + 1}

- \frac{3}{9} because \frac{2}{6}= \frac{1}{3} and \frac{1}{3} = \frac{3}{9}

- \frac{3}{12} because \frac{2}{6}= \frac{1}{3} and \frac{1}{3} = \frac{3}{9}

- \frac{3}{8} because \frac{2}{6}= \frac{1}{2} = \frac{2+1}{6+2} = \frac{3}{8}

Answer:

- \frac{3}{9} because \frac{2}{6}= \frac{1}{3} and \frac{1}{3} = \frac{3}{9}

Step-by-step explanation:

Two fractions are said to be equal if and only if they give the same value when simplified.

The equivalent of \frac{2}{6} is as explained in the selected option;

First, divide numerator and denominator by 2

\frac{2/2}{6/2}

Then simplify

2/2 = 1 and 6/2 = 3; So;

\frac{2/2}{6/2} = \frac{1}{3}

Multiply numerator and denominator by 3

\frac{1*3}{3*3} = \frac{3}{9}

Hence, \frac{2}{6} is equivalent to \frac{3}{9}

Someone please answer its due by midnight
Kobotan [32]

Answer:

Look below :)

Step-by-step explanation:

1. coefficient

2. constant (it's referred to as a constant because the value never changes)

3. This polynomial has 4 terms. We know this by counting them. 5x^3 is one term, -x^2 is the second term, 5x is the third term, and -8 is the fourth term.

4. In descending order: 2, 1, 3, 4. The degree is the same value as the exponent. For the last term, x^2y^2, you add the values of the exponents together to get the degree.

5. -2 is the coefficient. The term with the third degree, or has 3 as the exponent, is -2x^3.

6. 1 is the coefficient. The term with the second degree is x^2. When the coefficient is 1, usually the 1 isn't written because any number multiplied by 1 equals that number (x * 1 = x)

7. 5 is the degree of the polynomial. To find the degree of a polynomial, find whichever term has the highest value for an exponent. In this case, 5 is the highest exponent.

8. 2 is the degree of this polynomial. Although none of the terms may look like they have a degree of 2, in order to find the actual degree of 4xy you have to add the values of the degree of x and y to find the actual degree. If x and y both have a degree of 1, you add those together to make 2.

9. 2x^{3} - 7x^{2} + 5x - 15. To order a polynomial from highest to lowest you have to order the terms in decreasing value of their exponents.

10. -4x^{3} y + 2xy + 5x + 7.

I hope this helps :)
