How do you find the vertex if the equation is given ingiven in factored form?

Mathematics

lidiya [134]3 years ago

If the equation is given in factored form and the roots are real, then you can identify the x-coordinate of the vertex by averaging the 2 root values.  For example, if the roots are -2 and 5, the x-coord. of the vertex is (-2+5)/2, or 3/2.

Once you have this x value, subst. the value into the given equation to calculate y.  Then write the vertex as (x,y).

Why is it that the orthocenter of an obtuse triangle must lie on the outside of the triangle?
Taya2010 [7]
It is important to understand the meaning of orthocenter in respect to a triangle first. Ii is actually the intersection of all the altitudes within a triangle. The altitudes can be drawn from an angle to the opposite side but the line should create a right angle with the side of the triangle. In case of obtuse triangle, the three lines would meet outside the triangle. I hope the answer helps.

Find the slope and y-intercept of this linear function:<br> 2x + x = 4(y - 1)
photoshop1234 [79]

Answer:

  • slope: 3/4
  • y-intercept: 1

Step-by-step explanation:

Solve for y to put the equation in slope-intercept form.

  3x = 4y -4 . . . . . eliminate parentheses, collect terms

  3x +4 = 4y . . . . . add 4

  y = 3/4x +1 . . . . . divide by 4

The slope is the x-coefficient: 3/4.

The y-intercept is the constant: 1.

5 square root 13^3. <br> A 13^2. <br> B 13^15 <br> C 13^5/3. <br> D 13^3/5
arlik [135]
Answer is D.

When you have an exponent that is a fraction, the denominator is the number you root the base by. In this case the exponent is 3/5, so you fifth root 13 cubed.
