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.
Would you do 16 times 11 which equals 176
Answer:
Step-by-step explanation:
hello :
the x interception for Y=2x +7 when Y=0 means : 2x +7=0
so x = -7/2
Tangent = opposite/adjective
tan(C) = c/a
We can use an inverse ratio to find the measure of <C.
C = tan^-1(c/a)
difference between standard deviation and mean deviation
Answer:
Standard deviation is basically used for the variability of data and frequently use to know the volatility of the stock. A mean is basically the average of a set of two or more numbers. Mean is basically the simple average of data
Hope this helps!!
