Answer:
Lev is incorrect because (9, 4) is not a solution to the equation.
Step-by-step explanation:
We are given the equation: 3y - 2x = 19
When we are to check if an ordered pair is a solution to an equation, we substitute the pair in the equation and compare the RHS and LHS.
If they come to be equal then we can say that the given pair is indeed a solution to the equation.
So, here, RHS = 19
LHS = 3(4) - 2(9) = 12 - 18
= -6
19
i.e., LHS ≠ RHS
So, we can say that (x, y) = (9, 4) is not a solution to the given equation.
Answer:
The midpoint is ( 1, -1.5)
Step-by-step explanation:
To find the midpoint
Add the x coordinates of the endpoints and divide by 2 to get the x coordinate of the midpoint
(5+-3)/2 = 2/2 = 1
Add the y coordinates of the endpoints and divide by 2 to get the y coordinate of the midpoint
(3+-6)/2 = -3/2 = -1.5
The midpoint is ( 1, -1.5)
Answer:
smalls
Step-by-step explanation:
The answer is 20 slices
8/0.4 = 20
Answer: Since you already know that the ordered pair is in the format of (x, y), then you can label one of the ordered pairs as 1 and kind of distribute it to get 1(x, y) = (x-sub1, y-sub1). Then just use the slope formula (y2-y1)/(x2-x1).
