Twice the sum of a number and 9 equals 6
Korvikt [17]
Let's make the equation.
2(N+9)=6
Let's divide both sides by 2.
n+9=3
Now subtract 9 from both sides.
n=-6
So, the number is -6.

Drag the tiles to the correct boxes to complete the pairs. Solve the inequalities for x, and match each solution to its number l
svetlana [45]

in the figure, the first number line goes with x \leq5

the second number line goes with x \geq 5

the third number line goes with x > 5

the fourth number line goes with x < 5

Two less than 3/2 of a number x is  no more than 5/2 is shown as:

3/2 x- 2 \leq 5 1/2

3/2 x \leq 11/2 + 2

3/2 x \leq 15/2

3x \leq 15

x \leq 5

The sum of two times a number (x) and -2 is at least 8 is shown as :

2x+(-2) \geq 8

2x - 2 \geq 8

2x \geq 8+2

2x \geq 10

x \geq 5

Seven subtracted from 4 times a number (x) is more than 13 is shown as

4x -7 > 13

4x > 13+7

4x > 20

x > 20 ÷ 4

x > 5

Four added to 3 times a number (x) is less than 19 is shown as

3x + 4 < 19

3x < 19-4

3x < 15

x < 15 ÷ 3

x< 5

which is steeper a hill that rises 2 feet for every 10 feet of run, or a hill that rises 2 feet for every 15 feet of run? Explai
spayn [35]
In order to figure this out you need to use slope intercept for for each of these hills. Let's say the first hill is HA and the second hill is B

slope intercept: y = mx + b

HA: y = (2/10)x
HB: y = (2/15)x

As you can see when you plot this on a graph, HB is steeper because the line rises more sharply.

What is the inverse of this function?​
kolbaska11 [484]

Answer:

f^{-1}(x)=4x^2-3

Step-by-step explanation:

<u>The Inverse of a Function</u>

Given a function f(x), the inverse of f, called f^{-1}(x) is a function that satisfies:

f(f^{-1}(x))=x

The domain of f becomes the range of its inverse and vice-versa.

The procedure to find the inverse of the function is:

* Write the function as a two-variable equation:

* Solve the equation for x.

* Swap the variables

We are given the function:

\displaystyle f(x)=-\frac{1}{2}\sqrt{x+3}

Defined in the interval x ≥ -3

Note f is always negative, thus its range is f(x) ≤ 0

Now we find the inverse. Call y=f(x):

\displaystyle y=-\frac{1}{2}\sqrt{x+3}

Multiplying by 2:

\displaystyle 2y=-\sqrt{x+3}

Squaring both sides:

\displaystyle 4y^2=x+3

Subtracting 3:

\displaystyle 4y^2-3=x

Swapping variables:

y=4x^2-3

Thus:

\mathbf{f^{-1}(x)=4x^2-3}

The domain of the inverse is the range of f, thus x is restricted to

x ≤ 0
