The first is a right triangle because there is a right angle, and it is scalene because none of the sides are congruent.
The second is an obtuse triangle because there is an obtuse angle, and it is an isosceles triangle because two of the sides are congruent.
The third is an acute triangle because all of the angles are acute, and it is an <span>isosceles triangle because two of the sides are congruent.
The fourth is a right triangle because it has a right angle, and it is a s</span><span>calene because none of the sides are congruent.</span>
Multiply the first equation by 2:-
2y + 4.6 = 0.90x
2y - 0.90x = -4.6
second equation is
-2y - 4.2x = -7.8
Adding:-
-5.1x = -12.4
x = 2.4
-2y = -7.8 + 4.2(2.4) = 2.3
x = -1.2
Answer x = 2.4 and y = -1.2
Its choice A
The value of x in terms of p is 15/p.
The value of x when p is -5 is -3.
Pls tell me if i’m wrong in any way!
ANSWER
The graph in option D.
EXPLANATION
The given function is:
![y = 3 {x}^{2} - 12x + 10](https://tex.z-dn.net/?f=y%20%3D%203%20%7Bx%7D%5E%7B2%7D%20%20-%2012x%20%2B%2010)
We complete the square to obtain:
![y = 3( {x}^{2} - 4x) + 10](https://tex.z-dn.net/?f=y%20%3D%203%28%20%7Bx%7D%5E%7B2%7D%20%20-%204x%29%20%2B%2010)
![y = 3( {x}^{2} - 4x + {( - 2)}^{2} ) + 10 - 3 {( - 2)}^{2}](https://tex.z-dn.net/?f=y%20%3D%203%28%20%7Bx%7D%5E%7B2%7D%20%20-%204x%20%2B%20%20%7B%28%20-%202%29%7D%5E%7B2%7D%20%29%20%2B%2010%20%20-%20%203%20%7B%28%20-%202%29%7D%5E%7B2%7D)
![y = 3{( x- 2)}^{2}+ 10 - 12](https://tex.z-dn.net/?f=y%20%3D%203%7B%28%20x-%202%29%7D%5E%7B2%7D%2B%2010%20%20-%2012)
![y = 3{( x- 2)}^{2} - 2](https://tex.z-dn.net/?f=y%20%3D%203%7B%28%20x-%202%29%7D%5E%7B2%7D%20%20-%202)
The graph of this function opens upwards and has its vertex at (2,-2).
The y-intercept is 10.
From the options the graph that satisfies all these properties is D.
