-1/2 - 3/5 ?? and in simplest form

Answers

Answer 1

Answer: First find common denominators.

-1/2
-3/5

Multiply 5 to numerator and denominator of (-1/2), and 2 to numerator and denominator for (-3/5).

(-1/2)(5/5) - 3/5(2/2)

Simplify:
-5/10 - 6/10

Combine terms.

-5 - 6 = -11

-11/10, or - 1 1/10 is your answer

hope this helps

Answer 2

Answer:

Simplest form of given expression, $-(1)/(2)-(3)/(5)$ is -11/10

A number that has a whole number and a fractional component separated by a decimal point is a decimal. The decimal point is the dot that appears between the parts of a whole number and a fraction.

Given expression, $-(1)/(2)-(3)/(5)$ can be solved as follows:

Take the LCM of denominator, LCM of 2 and 5 is 10.

Multiply first number by 5 and second number by 2 as follows:

$=-(1* 5)/(2* 5)-(3* 2)/(5*2)\n\n=-(5)/(10)-(6)/(10)\n\n=(-5-6)/(10)\n\n=-11/10$

Thus, $-(1)/(2)-(3)/(5)$ in its simplest form, is -11/10

Using the polynomials Q = 3 x2 + 5 x - 2, R = 2 - x2 , and S = 2 x + 5, perform the indicated operation. Q - [ R + S ]

Answers

Answer:

4x^2 + 3x - 9

Step-by-step explanation:

First, add together functions R(x) and S(x). Stack them vertically and combine like terms:

R(x) = 2 - x^2

S(x) = 2x + 5

------------------

(R+S)(x) = -x^2 + 2x + 7

Now subtract the above result from Q(x):

Q(x) - (R(x) + S(x)) = 3x^2 + 5x - 2 + x^2 - 2x - 7, or 4x^2 + 3x - 9

What is the slope of the line that passes through the points (14, 5) and (20, –4)? A. -3/2 B. -2/3 C. 2/3 D. 3/2

Answers

The slope of the line that passes through the points (14/5) and (20, -4), so you take y-y/x-x so you substitute the y's in for 5 and -4 and x in for 14 and 20.

Find an equation for the parabola with focus at (-5,-4) and vertex at (-5,-3)

Answers

Answer:

$(x+5)^(2)=-4(y+3)$

Step-by-step explanation:

Given:

Focus point = (-5, -4)

Vertex point = (-5, -3)

We need to find the equation for the parabola.

Solution:

Since the x-coordinates of the vertex and focus are the same,

so this is a regular vertical parabola, where the x part is squared. Since the vertex is above the focus, this is a right-side down parabola and p is negative.

The vertex of this parabola is at (h, k) and the focus is at (h, k + p). So, directrix is y = k - p.

Substitute y = -4 and k = -3.

$-4 = -3+p$
