Answer:
pkr 324
Step-by-step explanation:
Person A spent 2/3 of the total money spent, so ...
(2/3)(pkr 486) = pkr 324 . . . spent by person A
The graph is all the solutions to the equation bthat statement is true
the point ,(1,2) does lie on the graph
the other 2 are false
Let's simplify first
10x divided by 5 = 2x
Add 2x on 3 an you'll have 6x
And now you just combine like terms
which is x + 6x = 7x
So there's your answer 7x
You just need to replace the value of x and y in your expression. This gives us :
-12 * 5 - 4 * (-3) + 19 - 3*(-3) = -60 - (-12) + 19 - (-9) = -60 + 12 + 19 + 9 = - 20
Good luck for the next ones
Answer:
x = -7
Step-by-step explanation:
The vertex form of this equation tells us it is a downward-opening parabola with its vertex at (-7, -3). The line of symmetry is the vertical line through the vertex: x = -7.
___
Vertex form is ...
y = a(x -h) +k
where a is the vertical expansion factor, and (h, k) is the vertex. When a < 0, the parabola opens downward. When a > 0, it opens upward. (When a=0, the "parabola" is a horizontal line at y=k.)
