Consider any point P(x, y) in the coordinate axis.
The reflection of this point across the y-axis is the point P'(-x, y).
(x, y) and (-x, y) are the 'mirror' images of each other, with the y'axis as the 'mirror'.
For example the coordinates of the image of P(4, 13) after the reflection across the y-axis is P'(-4, 13)
or, if P(-5, -9), then P'(5, -9)
Answer: if coordinates of V are (h, k), coordinates of V' are (-h, k)
For this case we have that by definition, the roots, or also called zeros, of the quadratic function are those values of x for which the expression is 0.
Then, we must find the roots of:
Where:
We have to:
Substituting we have:
By definition we have to:
So:
Thus, we have two roots:
Answer:
In a cup, one tablespoon is 1/16. There are 16 tablespoons in a cup. 1 tablespoon also equals 3 teaspoons.
Answer:
Step-by-step explanation:
y/2 - 4 = x/3 can also be written as 1/2y - 4 = 1/3x
slope intercept form is y = mx + b
1/2y - 4 = 1/3x....multiply entire equation by 6, to get rid of fractions
3y - 24 = 2x ...add 24 to both sides
3y = 2x + 24....divide both sides by 3
y = 2/3x + 6 <===
