3/4” of a inch of stock is left
X=6 is a line parallel at x=6 to the y-axis
the line perpendicular to line x is parallel to x-axis at y= 7, hence this new line has a function y=7
Answer:
A the system has no solution
Step-by-step explanation:
Simplifying 2x + -5y = -8
Solving 2x + -5y = -8
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5y' to each side of the equation. 2x + -5y + 5y = -8 + 5y
Combine like terms: -5y + 5y = 0 2x + 0 = -8 + 5y 2x = -8 + 5y
Divide each side by '2'. x = -4 + 2.5y Simplifying x = -4 + 2.5y
Solution for 2x-5=12 equation:
2x - 5 = 12
2x = 12 + 5
2x = 17 (divide both sides by 2 to get x)
2x/2 = 17/2
x = 8.5
Answer: A, E, B, and C
Step-by-step explanation:
A regression procedure require all of the following
1. Linearity: The relationship between X and the mean of Y must always be linear. C fulfills this condition
2. Homoscedasticity: Sometimes known as the homogeneity of avariance is always same for any given value of X. A also fulfills this condition.
3. Normality: A fixed values of X, and Y is always normally distributed. B and E fulfills this condition.
Answer:
the y=x^2
Step-by-step explanation:
When you do inverses, you are also doing the inverse operation. The inverse y=x is y=x. The inverse of y= 2x+1 is y= 1/2x-1/2. How did I do that? You switch y and x in the equation and then solve for y. y= 2x+1 turns into x= 2y+1. Subtract 1, and then divide by two. (x-1)=2y---> 1/2x-1/2. But that is still a function, right? Then we are brought to y=x^2. The inverse operation is square rooting. y= sqrt(x). When you try to graph something square rooted you get a sideways parabola. When you draw a sideways parabola, you can see that it fails the vertical line test- so that one is not a function. Hope that helps!
