Answer:

A) y+7=-3(x-4)

Step-by-step explanation:

Hi there!

The given equations are written in point-slope form: y-y_1=m(x-x_1) where <em>m</em> is the slope of the line and (x_1,y_1) is a point that falls on the line

Notice how the line is travelling infinitely down as x increases. This means that the slope is negative.

Therefore, the equation of the line is either A or B.

Now, let's look at A:

y+7=-3(x-4)

This equation suggests that the point (4,-7) falls on the line, which it does.

Therefore, the equation of the graph is y+7=-3(x-4).

I hope this helps!

Find x such that 3^x = 27 mod 32 (b)
gregori [183]

Answer:

The value of x is 11.

Step-by-step explanation:

Consider the provided information.

It is given that 3^x = 27 mod\ 32

We know that:

3^4=81

Now if we divide the number 81 with 32 it will gives us remainder 17.

This can be written as:

3^4\equiv 17(mod\ 32)

Now use the property: a^n\equiv b^n(mod\ m)

(3^4)^2\equiv 17^2(mod\ 32)

17²=289, if we divide 289 with 32 it will gives us remainder 1, thus.

3^8\equiv 1(mod\ 32)

Multiply both the sides by 3³.

3^8\times 3^3\equiv 3^3(mod\ 32)

3^{11}\equiv 27(mod\ 32)

Hence, the value of x is 11.

Nookie1986 [14]
Answer: A) Copy the angle

When you are constructing triangles when given a Side, Angle, and Side (SAS), you should first copy one of the side. 

Then, you should copy the angle that is between the sides. (That is the answer to your question)

Finally, you will copy the last side. Then, you will have congruent triangles.
