Are you missing something?
2xy=7
5xy=9
does not have a solution.
If you mean
2x+y=7
5x+y=9
please say so.
It is 30000 i think dang it
Answer:
Step-by-step explanation:
x²=1.96
x²-1.96=0
(x+1.4)(x-1.4)=0
x=1.4 and -1.4
Answer:
y = -1/3x - 5 1/3
Step-by-step explanation:
Slope Intercept =
y=mx + b
Substitute the Slope
y= -1/3x + b
Substitute x and y from the point into the equation
-6 = -1/3(2) + b
-6 = -2/3 +b
Isolate the b with the addition property of equality
-5 1/3 = b
Substitute all variables
y = -1/3x - 5 1/3
The last statement
AD and DC are equal as shown by the small lines through them
DB is perpendicular and at exactly half way of line AC
Angles CBD and ADB are 92° and 88°
92 + 88 = 180
So the false one must be the last one.
