2. The quotient of a number and -9 increased by 10 is 11.

Answer:

Step-by-step explanation:

This question isn't worded the greatest, there are two ways you can read this.

1.  The quotient of a number and -9, increased by 10, is 11

2. The quotient of a number, and -9 increased by 10, is 11

The first equation will look like this

\frac{x}{-9} +10 = 11

And the second will look like this

\frac{x}{-9+10}   = -11

So I have solved for both (I personally believe the second way of reading the question is the correct way)

Answer:

10.9

Step-by-step explanation:

Pythagoras theorem- a² + b² = c²

Since this is a right angle with each side on the right angle's length given you can use pythagoras theorem.

7² + 8.44² = c²

= 49 + 70.56 = c²

= 119.56 = c²

∴ c = √119.56

= 10.9

If f(x) = 4x-3, which of the following is the inverse of f(x)?
GalinKa [24]

Answer:

\huge\boxed{f^{-1}(x)=\dfrac{x+3}{4}=\dfrac{1}{4}x+\dfrac{3}{4}}

Step-by-step explanation:

f(x)=4x-3\to y=4x-3\\\\\text{exchange}\ x\ \text{to}\ y\ \text{and vice versa}\\\\x=4y-3\\\\\text{solve for}\ y\\\\4y-3=x\qquad|\text{add 3 to both sides}\\\\4y-3+3=x+3\\\\4y=x+3\qquad|\text{divide both sides by 4}\\\\\dfrac{4y}{4}=\dfrac{x+3}{4}\\\\y=\dfrac{x+3}{4}\to y=\dfrac{1}{4}x+\dfrac{3}{4}

PLEASE HELP WILL GIVE 1ST RIGHT ANSWER AS BRAINIEST
Ne4ueva [31]

Answer:

26π

Step-by-step explanation:

Hmm... This one is a little hard to understand because of the LaTeX.

Any way, way back to the question.  A useful piece of information:

<u>The formula for finding the circumference of a circle is 2πr or π · d :</u>

We first need to find out what x is.

Since 2 times the radius is the diameter, we can set up our equation like this:

2(x + 6) = 3x + 5

Solving gives:

2x + 12 = 3x + 5.

We subtract 2x from both sides:

+12 = x + 5

Subtract 5:

So x = 7.

Now we can plug-and-chug:

7 + 6 = 13 times 2pi (this is the radius)

21 + 5 = 26 times pi.

<u>Check:</u>

When we check 13 (radius) times 2 should equal the diameter(26)

13 * 2 = 26.

So we are correct. The answer 26π is correct.

Need help with question 5 please
tatyana61 [14]

Answer:

-1/6

Step-by-step explanation:

To find the slope we use

m = (y2-y1)/(x2-x1)

    = (-4-8)/( 1-3)

    = -12/-2

    =6

We want a line perpendicular, so we need the negative reciprocal

- (1/6)

-1/6
