Answer:
x = ±1
Step-by-step explanation:
We have to assume you want the solution for y = 0:
0 = x² -1
1 = x² . . . . . . add 1
±1 = x . . . . . . take the square root
x = ±1
Answer:
15
Step-by-step explanation:
multiply both sides by 15
45x=675
Divide both sides by 45
x=15
An equation is formed of two equal expressions. The equation of the exponential graph is A=100(0.5)ˣ.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The equation of an exponential function is given by the formula,
y = A (B)ˣ
Now as per the graph, there are two points (1, 50) and (2, 25).
50 = A (B)¹
50 = AB
A = 50/B
Substitute another point in the equation,.
25 = A (B)²
25 = (50/B) (B)²
25 = 50B
B = 0.5
Substitute the value of B,
A = 50/0.5 = 100
Hence, the equation of the exponential graph is A=100(0.5)ˣ.

I think its idfk…maybe?!?
There are 6 sides on a die, so there are 6 numbers: 1, 2, 3 ,4 ,5 and 6.
The probability of rolling a 6 would be 1 out of 6 numbers which is written as 1/6.
