This is not an equation and thus cannot be solved for x. Ensure that you have copied down the original problem exactly.
If, on the other hand, you meant x + 2x - 3 + x = - 4, you do have an equation and can solve for x as follows:
4x - 3 = -4 => 4x = -1 => x = -1/4
Circumference = 2 * PI * radius
radius = 50.24 / (6.28)
radius = 8
Answer: 3.75
Step-by-step explanation:
P=0.50, n=15
np= 0.5x15 gives 7.5
n(1-p)= 15x(1-0.5)=7.5
Both are greater than 5
Then Mean, u=np;15x0.5=7.5
Standard deviation, √np(1-p)
15x0.5(0.5)= 3.75
For functions, x’s can’t repeat, so looking at the first problem, C is the only one where the first number in each coordinate (x,y) doesn’t repeat.
For the second, x = -2 means that no x is always -2 matter which y you would look at. So x’s repeat and it forms a vertical line. So it is not a function
