Answer must be in fraction form

Damm [24]

Answer:

-7/18

Step-by-step explanation:

To multiply fractions, you just multiply the top number by the top number and the bottom number by the bottom number. Also, you have to watch the sign.

In this case, we have a positive fraction multiplied by a negative fraction, meaning that our answer must be negative.

So we have- 2x7 / 4x9.

This is simplified to be- 14/36, or 7/18.

However, the answer is actually -7/18, since the number must be negative.

Let me know if this helps.

Restrict the domain of the function f(x)=(x-2)to the power of 2 so it has an inverse. Then determine its inverse function.

nata0808 [166]

Answer:

Step-by-step explanation:

Given is a function

$f(x) =(x-2)^2$

This function is a parabola with vertex at (2,0) and axis of symmetry is x=2

Hence for x<2 the curve would be reflection of x>2

To get inverse we must get one to one funciton only.

So restrict the domain of f(x) to $[2,∞)$

Then we have f(x) as one to one with domain x≥2 and range is R+

$f^{-1} (x)=+\sqrt{x} +2$

For this inverse domain is R+ and range is $[2,∞)$

Three consecutive integers have a sum of -42. Write and solve an equation to find the three integers.

IrinaK [193]

Let the first integer be x.

Let the second integer be x + 1 .

Let the third integer be x + 2 .

<h2><u>According</u><u> to</u><u> the</u><u> </u><u>question</u></h2>

x + ( x + 1 ) + ( x + 2 ) = -42

Opening the brackets and simplifying :

x + x + 1 + x + 2 = -42

3x + 3 = -42

Now , solving equation :

$\bf \rightarrow \: \:3x \: + \: 3 \: = \: -42$

$\bf \rightarrow \: \: 3x \: = \: -42 \: - 3$

$\bf \rightarrow \:3x \: = \: -45 \:$

$\bf \rightarrow \:x \: = \: \frac{ - 45}{ \: 3} \\$

$\bf \rightarrow \:x \: = \: \cancel\frac{ - 45}{ \: 3} \: \: ^{ - 15} \\$

$\bf \rightarrow \:x \: = \: - 15$

${\boxed{ \Large{ \red{ \rm{ \underline{ Now \: \: substitute}}}}}}$

$\bf \implies \: \:x \: = \: - 15$

$\bf \implies \: \:x \: + \: 1 \: = \: - 15 \: + \: 1 \: = \: - 14$

$\bf \implies \: \:x \: + \:2 \: = \: - 15 \: + \: 2 \: = \: - 13$

-15 , -14 and -13 are the three consecutive integers.
