Answer:
x=6
Step-by-step explanation:
3(6)+1=18+1=19.
B equals c hope this helps :)
Answer:
Step-by-step explanation:
The equation of a straight line in slope intercept form is given by:
y = mx + c;
where y, x are variables, m is the slope of the line and c is the y intercept (that is value of y when x is 0).
The equation of a line passing through point () with a slope of -1/2 is given by:
Given that the line passes through the point (-10,9) and has a slope of -1/2. Hence the equation of the line is:
Good morning
x-3y=-3
x+3y=9
Solve x-3y=-3 for x
Add 3y to both sides
x-3y+3y=-3+3y
x= 3y-3
Substitute 3y-3 for x in x+3y=9
x+3y=9
3y-3+3y=9
Simplify both sides of the equation
6y-3=9
Add 3 to both sides
6y-3+3=9+3
6y=12
Divide both sides by 6
6y/6=12/6
y=2
Substitute 2 for y in x=3y-3
x=3y-3
x= (3)(2)-3
x= 6-3
x= 3
Final answer : X=3, Y=2
I hope that's help !
Have a great Sunday :)
That's the last one because you can factor to get
(x + 8)^2 = 36
(x + 8) = +/- 6
