x=0 is not the solution of this equation
you can put values and can check in these questions
Answer:
Step-by-step explanation:
Trick question. Good to know.
0 is the closest 100.
33 will round to 0
Let's say the price of one book is the variable x
Therefore, Alana is 5x and Petra is 4x
Angus bought 19x, but since he had a $10 discount, it is 19x-10
Combined, Alana and Petra is 5x+4x, but since it says Angus spent $5 more, it would be 5x+4x+5
Therefore, we get the equation:
19x-10=5x+4x+5
19x-10=9x+5
10x=15
x=15/10 or 3/2 which equals 1.5
Therefore, one book costs $1.5
Answer:
Center: (0,0)
Radius: 5
Step-by-step explanation:
Let O(xo,yo) be the center (of the circle) with the coordinates xo, yo.
If R is the radius, then we have:
(x-xo)²+(y-yo)²=R².
In our case: x²+y²=25, the center is at (0,0), and R²=25, so R=5
Answer:
First , her error is that the graph is not steep enough, including that her second point is (2,0) when it is actually (0.5,0)
The graph should actually look like this.
