write the multiplicative inverse of
a) -13/19​

Answers

Answer 1

Answer:

[tex] - \frac{19}{13} [/tex]

Step-by-step explanation:

[tex]the \: multiplicative \: inverse \: of \: \\ - \frac{13}{19} = - \frac{19}{13} [/tex]

Product of a number and its multiplicative inverse should be equal to 1.

So,

[tex] \bigg ( - \frac{13}{19} \bigg) \bigg ( - \frac{19}{13} \bigg) [/tex]

[tex]= \frac{13}{19}\times \frac{19}{13} [/tex]

[tex]=1 [/tex]

Answer: (b)

Step-by-step explanation:

Given

[tex]f(x)=x^2[/tex]

Now, [tex]f(x)[/tex] is transformed to [tex]g(x)[/tex]

and [tex]g(x)[/tex] is obtained by replacing [tex]x[/tex] with [tex]\frac{x}{2}[/tex] in [tex]f(x)[/tex]

[tex]\therefore g(x)=\left(\dfrac{x}{2}\right)^2\\\\g(x)=\dfrac{x^2}{4}[/tex]

Plot [tex]f(x)[/tex] and [tex]g(x)[/tex] and it can be observed that domain, range, and vertex is same for both the function.

[tex]f(x)[/tex] is narrower compared to [tex]g(x)[/tex]. Therefore, option (b) puts up the invalid reasoning. Hence option (b) is not a true statement.

Answer:

44 in.

Step-by-step explanation:

3 ft 8 in.

1 ft = 12 in.

3 ft = 36 in.

36 in. 8 in.

44 in.

A state in the United States has 193,116 residents living in 22 countries.

[tex]\frac{1}{y} :\frac{22}{193,116}[/tex]

y · 22 = 1 · 193,116

22y = 193,116

22y ÷ 22 = 193,116 ÷ 22

y = 8778

The rate is 8778.

PLEASE HELP ME :(. Look at this system of equations.
X - 8y = -3
5x - 2y = 4
What value of a will make this system have the same solution?
ax = -19
5x - 2y = 4

Answers

9514 1404 393

Answer:

  a = -19

Step-by-step explanation:

In the first set of equations, subtract 4 times the second equation from the first.

  (x -8y) -4(5x -2y) = (-3) -4(4)

  -19x = -19 . . . . simplify

Comparing this to the equation ...

  ax = -19

we see that they will have the same solution when a = -19.

7 is the degree of the given polynomial  P(x)=3x⁴-7x²-2x⁷-x+4

What is Polynomial?

Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables.

The given polynomial is  P(x)=3x⁴-7x²-2x⁷-x+4

Three time of x to the power of four minus seven times of x square minus two times of x power seven minus x plus four.

A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.

In the given polynomial the x variable has 7 as the highest power.

So 7 is the degree of the given polynomial

Hence  7 is the degree of the given polynomial  P(x)=3x⁴-7x²-2x⁷-x+4
