Hi!

Switch up the variables:

y = -14x - 2.

x = -14y - 2.

Add 2 to both sides.

x + 2 = -14y - 2 + 2.

x + 2 = -14y.

Divide by -14 on both sides.

(x + 2) / -14 = -14y / -14.

(x + 2) / -14 = y.

Change the y to f^-1(x).

f^-1(x) = (x + 2) / -14.

Hopefully, this helps! =)

Which of the following functions have a vertical asymptote for values of Ø such that cos Ø = 1?Select all that apply.

igomit [66]

Answer:

$y=\cot \theta$ and $y=\csc \theta$

Step-by-step explanation:

Note that if $\cos \theta=1,$ then $\sin \theta=0.$

Functions $y=\cos \theta,\ \ y=\sin \theta$ do not have vertical asymptotes at all.

Vertical asymptotes have functions $y=\tan \theta,\ \ y=\cot \theta,\ \ y=\sec \theta,\ \ y=\csc \theta.$

Functions $y=\tan \theta$ and $y=\sec \theta$ have the same vertical asymptotes (when $\cos \theta =0$ ).

Functions $y=\cot \theta$ and $y=\csc \theta$ have the same vertical asymptotes (when $\sin \theta =0$ ). See attached diagram

Solve the simultaneous equations y=3x+2 and y=x+6

kogti [31]

Answer:

x=2

Step-by-step explanation:

y=3x+2

y=x+6

Since you're stating that, they both equal because equation is equated to equation 2 because of the Y.

Therefore, substitute into both equations as shown:

3x+2=x+6

3x-x=6-2 (bring 2 to the other side by subtracting 2 as well as x)

2x=4

2x/2=4/2 (dividing 2 on both sides to get rid off 2 in 2x)

x=2.

The budget for a school dance is $390.00. Decorations and refreshments cost $150.00. The band charges a fee of $100.00 plus an a

Papessa [141]

Answer:

The maximum number of hours the school can have the band play at the dance is 4.

Step-by-step explanation:

150 + 100 + 35x ≤ 390

250 + 35x ≤ 390

subtract 250 from both sides

35x ≤ 140

divide by 35 on both sides

x ≤ 4

What is the factorization of 2x^2+5x+3

nataly862011 [7]

Answer:

The answer is

<h2>(2x + 3)(x + 1)</h2>

Step-by-step explanation:

<u>Write 5x as a sum</u>

2x² + 2x + 3x + 3

Factorize x out

That's

2x ( x + 1) + 3( x + 1)

The final answer is

(2x + 3)(x + 1)

Hope this helps you.
