Help clear the fractions I need more help

marishachu [46]

Answer:

x = $\frac{43}{6}$

Step-by-step explanation:

Given

$\frac{3}{4}$ x - 5 = $\frac{3}{8}$

Multiply through by 8 ( the LCM of 4 and 8 ) to clear the fractions

6x - 40 = 3 ( add 40 to both sides )

6x = 43 ( divide both sides by 6 )

x = $\frac{43}{6}$

MARK AS BRAINLEST

WARRIOR [948]

Answer:

{- 2, - 4, - 6, - 8, - 10 }

Step-by-step explanation:

Given

f(x) = 2x - 6 with domain { - 2, - 1, 0, 1, 2 }

To obtain the range substitute the values of x from the domain into f(x)

f(- 2) = 2(- 2) - 6 = - 4 - 6 = - 10

f(- 1) = 2(- 1) - 6 = - 2 - 6 = - 8

f(0) = 2(0) - 6 = 0 - 6 = - 6

f(1) = 2(1) - 6 = 2 - 6 = - 4

f(2) = 2(2) - 6 = 4 - 6 = - 2

Range is { - 2, - 4, - 6, - 8, - 10 }

Which of the following is a polynomial?

Makovka662 [10]

Answer:

Step-by-step explanation:

Terms are separated by addition and subtraction symbols.

Polynomials consist of terms that are constant and/or variable. The variable terms must have 0 or positive exponents. Polynomials will not consist of division of variable expressions.

Examples of polynomials:

$5$

$5x$

$6-x$

$24x^9-x$

Examples of non-polynomials:

$\sqrt{x}$

$\frac{x+2}{x-4}$

In general a polynomial when written in standard form should be comparable to:

$a_nx^n+a_{n-1}x^{n-1}+\cdots a_3x^3+a_2x^2+a_1x+a_0$

where the $a$ 's could be zero and all the exponents,n, are positive or 0.

D is comparable since all of these are 0 except $x_4$ which is 1 and $x_0$ which is -2.

Also the other choices have either division by variable expressions and/or negative exponents on variables.

X-y=-3<br> Anyone know how to do this ?

horsena [70]

X - y = -3

Move constant to the left by adding its opposite to both sides

x - y + 3 = -3 + 3

The sum of two opposites equals

your answer would be: x - y + 3 = 0
