Which of the following points satisfies the inequality

Wewaii [24]

Answer:

C. (0, -3)

Step-by-step explanation:

Replace the y with -3 and the x with 0, which makes it, -3 < -4(0) + 3.

Multiply -4 by 0 and you get 0 as the answer. So now the inequality is

-3 < 0 + 3. Adding the 0 doesn't do anything, so the inequality is -3 < 3, which would be correct.

Explain how to solve 2^x + 1 = 9 using the change of base formula log base b of y equals log y over log b. Include the solution

elena55 [62]

Answer:

$x=2.170$

Step-by-step explanation:

The given equation is $2^{x+1}=9$ .

We take logarithm of both sides to base 2 to get:

$\log_2(2^{x+1})=\log_29$

Apply the power rule of logarithms to get:

$x+1=\log_29$

We now apply the change of base formula:

$x+1=\frac{\log_{10}9}{\log_{10}2}$

$x+1=\frac{0.9542}{0.3010}$

$x+1=3.1701$

$x=3.1701-1$

$x=2.1701$

To the nearest thousandth, $x=2.170$

According to the diagram, how far is point L from Rays KH and HF?Find the value of Y

RideAnS [48]

Answer:

The distance between L and the line KH and HF is;

$27$

The value of y is;

$y=9$

Explanation:

Given the figure in the attached image;

$\begin{gathered} KL=27 \\ KHL=(6y)^{\circ} \\ FHL=(4y+18)^{\circ} \end{gathered}$

From the image;

$KL=FL=27$

So, the distance between L and the line KH and HF is;

$27$

Also, the triangles KHL and FHL are congruent.

So, the angles KHL and FHL are congruent.

$m\measuredangle KHL\cong m\measuredangle FHL$

Substituting the expressions;

$\begin{gathered} (6y)^{\circ}=(4y+18)^{\circ} \\ 6y=4y+18 \\ 6y-4y=18 \\ 2y=18 \\ y=\frac{18}{2} \\ y=9 \end{gathered}$

Therefore, the value of y is;

$y=9$
