Answer:

Step-by-step explanation:

Simplifying

5 + -2x = 4 + -2x + 4 + x

Reorder the terms:

5 + -2x = 4 + 4 + -2x + x

Combine like terms: 4 + 4 = 8

5 + -2x = 8 + -2x + x

Combine like terms: -2x + x = -1x

5 + -2x = 8 + -1x

Solving

5 + -2x = 8 + -1x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'x' to each side of the equation.

5 + -2x + x = 8 + -1x + x

Combine like terms: -2x + x = -1x

5 + -1x = 8 + -1x + x

Combine like terms: -1x + x = 0

5 + -1x = 8 + 0

5 + -1x = 8

Add '-5' to each side of the equation.

5 + -5 + -1x = 8 + -5

Combine like terms: 5 + -5 = 0

0 + -1x = 8 + -5

-1x = 8 + -5

Combine like terms: 8 + -5 = 3

-1x = 3

Divide each side by '-1'.

x = -3

Simplifying

x = -3

What is the vertex of the graph of the function below?

Free_Kalibri [48]

Since y = x2 - 8x + 12 is a quadratic equation, it is the same of y=ax²+bx+c
the main formula of the vertex is x= -b/2a, and y=f(-b/2a)

for our case x= -(-8) / 2=4, and f(4)= -4

the answer is B. (4, -4)

Question 10 (2 points)

igomit [66]

Answer:

a = 2

Step-by-step explanation:

To find the missing length we can use the Pythagorean theorem. Also, because it's a right triangle it makes it the perfect candidate!

The Pythagorean Theorem states:

a^2 + b^2 = c^2

Next, we substitute the letters with our given numbers (keep in mind that c is the hypotenuse which is the side facing the right angle)

a^2 + 2.1^2 = 2.9^2

Finally, we solve our equation (hint: use the calculator if needed)

a^2 = 4 (your answer is not final yet. You have to take the square root of both numbers)

a = 2 (Now that's the final answer!)

My brother has to make a polygon with 5 verticals and 3 sides that are the same length, does anyone have any clue what that woul

Mademuasel [1]

Answer:

In the polygon there are as many vertices as there are sides. The triangle has 3 sides and 3 vertices. The quadrilateral has 4 sides and 4 vertices. The pentagon has 5 sides and 5 vertices.

Try to figure out what this means and this should help
