Answer:
The answer us B y= -8/7x -18/7
Answer:
x=10t+25
Step-by-step explanation:
The delivery fee is 25 dollars and each shirt is 10 dollars
8^-5 / 8^-3
= (1/8^5 ) / (1/8^3)
=1/8^2
answer is <span>A. one divided by the quantity eight squared</span>
Answer:
Center: 2, -3
Radius: 7
Step-by-step explanation:
The center of the circle is defined by the numbers subtracted from the variables. The x value for the center is 2, since it is x - 2, and the y value is -3, because y - -3.
The radius is equal to the square root of the constant on the other side.
The square root of 49 is 7.
Putting the equations into standard form helps me identify dependent and inconsistent systems. In standard form, the leading coefficient is positive, and all numbers are mutually prime (have no common factors).
1.) 2x + y = -9 . . . . . . multiply the original equation by -1
... 3x - 4y = -8 . . . . . . the system is independent
These two equations will give rise to a single solution.
_____
2.) 4x + y = 4 . . . . . . divide the original equation by 3
... 4x + y = 5 . . . . . . . the system is inconsistent
These two equations describe parallel lines, so will not have a point of intersection. There are no values of x and y that can satisfy both equations.
