Answer:

The person that answered at the top is a legend!! The picture below is just proof that he/she is right!! :)

Step-by-step explanation:

9514 1404 393

 see attached Starting with the original function, swap the variables x and y, then solve for y. The resulting function is the inverse of the original function.

i hope this help's pleazz dont report me okay

Answer: See below

Step-by-step explanation:

The y=4x+7 box will go first as it's the initial equation

Then x=4y+7 as to find the inverse of an equation you replace x with y and y with x

After that, it's the x-7=4y box as the first step for solving for y is subtracting 7 from both sides

Then it will be x-7/4 = y as you divide by 4 to isolate y

The last box will be f^-1(x)=x-7/4 as you clean up by switching sides and adding f^-1(x) denoting that it is the inverse of f(x) = 4x + 7

Hope this helps ;)

The expression n2 + n represents the total number of blocks used in the nth figure of a pattern. Use the equation n2 + n = 56 to
Brrunno [24]

We have to solve this quadratic equation n^{2}+n=56 for n to get <em>which figure has 56 blocks</em>.

n^{2}+n=56\\n^{2}+n-56=0

For middle term factorization, we need <em>two numbers that multiplied gives us -56 and added gives us 1 (coefficient of n).</em>

<em>Such two numbers are </em><em>8</em><em> and </em><em>-7</em><em>. We can now write,</em>

<em>n^{2}+n-56=0\\(n+8)(n-7)=0\\n=-8, 7</em>

<u><em>"There is no negative figure number possible, so we disregard -8"</em></u>

Our answer is 7.


ANSWER: The 7th figure has 56 blocks.

Which equation describes a line that passes through (-6, 8) and is parallel to the line described by y = 2x − 4?
AleksandrR [38]

Answer:

hey, there!

Step-by-step explanation:

The given is a point (-6,8) through which a line passes. And is perpendicular to the line y = 2x-4

The equation for point (-6,8) is,

(y-8)= m1(x+6)...........(i)

and given equation is y = 2x-4............(ii)

Now, from equation (ii).

slope (m2)= 2 { as equation (ii) is in the form of y= mx+c where m is a slope}.

Now, For perpendicular,

m1×m2= -1

m1×2= -1

Therefore, m1 = -1/2.

Putting, the value of m1 in equation (i).

(y-8) = -1/2×(x+6)

2(y-8)= -1(x+6)

2y - 16 = -x -6

x+2y-10 = 0......... is the required equation.

Hope it helps...
