Answer: 49

Step-by-step explanation:

The sum of the angles of a triangle must be equal to 180º. We already know 2 of the three angles, therefore we can make an equation to find x.

41º+90º+x=180º

131º+x=180º

x=180º-131º

x=49º

Answer:

49°

Step-by-step explanation:

interior angles of a triangle add to 180

x + 41+90 = 180

180-90-41=x

x=49

How do I solve -2y = 34 ??

weeeeeb [17]

Answer:

y= -17

Step-by-step explanation:

In order to solve for y you need to get y by itself on one side of the equation.

This is very simple and all you need to do is divide each side by -2.

$-2y=34$

/-2 /-2

y= -17

34 divided by -2 is -17

Answer:

There is a common ratio of 1/4.

The next 3 numbers are -80, -20 , -5.

Step-by-step explanation:

The next term is found by multiplying by 1/4. ( -5120 / 20480 = 1/4).

So the next 3 terms are -320 * 1/4 = -80,

-80 * 1/4 = -20 and the last is -5.

Which of the following is the function f(x) if f'(x) = *#4?

TEA [102]

Answer:

Step-by-step explanation:

To find a function's inverse, you first switch the x and y coordinates, and then solve for the new y. The same goes for finding an inverse's function. We have:

$y=\frac{x+4}{11}$ We will switch the x and y variables and then solve for the new y:

$x=\frac{y+4}{11}$ and

11x = y + 4 so

11x - 4 = y and

11x - 4 = f(x) which is choice C.

If h(x) = 6 - X, what is the value of (h*h)(10)?

Vikentia [17]

The value of $\bold{ h(h(10))=10}$

Solution:

Given: $h(x) = 6 - x$

To find: The value of (h*h)(10)

We know that, $(h*h)(x)=h(h(x))$

which is,

$\Rightarrow h(h(x))=6-(6-x)=x$

On solving we get,

$\Rightarrow6-6+x=x$

So, for x = 10 it will be,

$h(h(10))=10$

Hence, the required value is 10.
