Answer:
c. (x -6, y +8)
Step-by-step explanation:
We can tell which answer to choose by looking at the change in the y-coordinate. Point Y is (4, -4). Point Y' is (-2, 4). The new y-coordinate has been translated upward by ...
4 -(-4) = 8 . . . units
That is, y' = y +8. This matches choice C.
The translation of Y(4, -4) to Y'(-2, 4) is described by ...
(x, y) ⇒ (x -6, y +8)
Y(4, -4) ⇒ Y'(4 -6, -4 +8) = Y'(-2, 4)
Remember some basic rules
and
![x^ \frac{m}{n}= \sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%20%5Cfrac%7Bm%7D%7Bn%7D%3D%20%5Csqrt%5Bn%5D%7Bx%5Em%7D%20%20)
so
1/2-2/7=
7/14-4/14=
3/14
![x^ \frac{3}{14}= \sqrt[14]{x^3}](https://tex.z-dn.net/?f=x%5E%20%5Cfrac%7B3%7D%7B14%7D%3D%20%5Csqrt%5B14%5D%7Bx%5E3%7D%20%20)
15x + 30y = -10....reduce by dividing by 5
3x + 6y = -2...same as first equation...same line ..means infinite solutions
Answer:
x = 8°
y = 6°
Step-by-step explanation:
Hello!
All 3 sides of the triangle are equal, indicating that it is an equilateral triangle. The rules of this particular triangle say that all angles are equal to 60°.
We can solve for x by setting the equation 7x+4 to 60.
<h3>Solve for x</h3>
- 7x + 4° = 60°
- 7x° = 56°
- x = 8°
The value of x is 8°.
We can go ahead and solve for y by setting that equation to 60°.
<h3>Solve for y</h3>
- 8y + 12° = 60°
- 8y = 48°
- y = 6°
The value of y is 6°.
