The answer to this equation is -24 because in each of the parentheses the product is -12 and negative numbers add to each other

Answer:

-24

Step-by-step explanation:

Use PEMDAS or PEDMAS to solve for this. The P stands for parentheses, meaning you must add,subtract,divide,or multiply anything in the parentheses first. Multiplying -4 and 3 would equal -12 and multiplying -3 and 4 would also equal -12. You then add those two values together as such (-12)+(-12) which would equal -24

The graph of an inverse trigonometric function passes through the point (1, pi/2). Which of the following could be the equation

rodikova [14]

Answer: C) $y=sin^-1 x$

Step-by-step explanation:

Since, the graph of an inverse trigonometric function will pass through the point $(1,\frac{\pi}{2})$ ,

If this point satisfies the function,

For the function $y=cos^{-1} x$

If x = 1

$y=cos^{-1}1=0$

Thus, $(1,\frac{\pi}{2})$ is not satisfying function $y=cos^{-1} x$ ,

⇒ The graph of $y=cos^{-1} x$ is not passing through the point $(1,\frac{\pi}{2})$

For the function $y=cot^{-1}x$

If x = 1

$y=cot^{-1}1=\frac{\pi}{4}$

Thus, $(1,\frac{\pi}{2})$ is not satisfying function $y=cot^{-1}x$ ,

⇒ The graph of $y=cot^{-1}x$ is not passing through the point $(1,\frac{\pi}{2})$

For the function $y=sin^{-1} x$

If x = 1

$y=sin^{-1}1=\frac{\pi}{2}$

Thus, $(1,\frac{\pi}{2})$ is satisfying function $y=sin^{-1} x$ ,

⇒ The graph of $y=sin^{-1} x$ is passing through the point $(1,\frac{\pi}{2})$ .

For the function $y=tan^{-1}x$

If x = 1

$y=tan^{-1}1=\frac{\pi}{4}$

Thus, $(1,\frac{\pi}{2})$ is not satisfying function $y=cos^{-1} x$ ,

⇒ The graph of $y=tan^{-1} x$ is not passing through the point $(1,\frac{\pi}{2})$ .

Hence, Option C is correct.

3(x - 4) + 9 = 18<br><br> Step by step (and explanation)

Andrews [41]

Answer:

= 7

Step-by-step explanation:

3(x−4)+9=18

3 − 1 2 + 9 = 1 8

3 − 3 = 1 8

3 = 1 8+3

3 = 21

x= 21/3

x=7
