Those are adjacent angles. They equal 180 degrees. 

10x-20+6x+8= 180

16x-12=180

Add 12.

16x= 192

x=12

I hope this helps!

Helllp pleaseeee!!!!<br><br><br> Solve for x.<br> 2^4x=8^3x-10
igomit [66]

Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

(24)(x)=(83)(x)−10

Step 1: Simplify both sides of the equation.

(24)(x)=(83)(x)−10

16x=512x+−10

16x=512x−10

Step 2: Subtract 512x from both sides.

16x−512x=512x−10−512x

−496x=−10

Step 3: Divide both sides by -496.

−496x

−496

=

−10

−496

x=

Mean of all scores means add them all up then divide by number of scores (5)

so
the mean has to be at least 95 aka, greater than or equal to 95
so
represent the last score with x
mean is the sum of all scores

\frac{96+93+97+92+x}{5} \geq 95
\frac{378+x}{5} \geq 95
multiply both sides by 5
378+x \geq 475
minus 378 from both sides
x \geq 97

he has to get at least 97 on the last test to get the highest score
good luck, marvin

A quadratic function is described by the equation f(x) = (x - 3) ^ 2 Which statement about the graph of the function is true?
Bond [772]

Answer: A) The only zero of the function is 3 which is where the graph of the function intersects the x-axis

Step-by-step explanation:

Remember, a quadratic function which has roots x = a, and x = b, can be written as:

p(x) = A*(x - a)*(x - b)

Where A is the leading coefficient. This is the factorized form of a quadratic.

We have the function:

f(x) = (x - 3)^2

Now, we could rewrite this as:

f(x) = (x - 3)*(x - 3) = 1*(x - 3)*(x - 3)

Then we wrote f(x) in its factorized form, from this, we can see that the roots of the function are x = 3, and x = 3 (we have the same root two times)

Then the only root of f(x) is x = 3.

Remember that a root (also called a zero) is the value of x where the function intersects the x-axis. then the correct option here is:

A) The only zero of the function is 3 which is where the graph of the function intersects the x-axis
