If f(x)=-3x-2, find x so that f(x)=-9.5

X = -2.5 .

Step-by-step explanation:

Here given,

- 3x-2

We have to find out the the x and from that value we should get -9.5. Let's see step by step solution:

=> 3x = 9.5 + 2 [ By replacing the position of - 2 from left side to right side]

=>  3x= -7.5

=> x =

=> x= -2.5

Now putting the value in the place of x we get,

3 (-2.5) -2 = -9.5

So, the x will be -2.5 .

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
