Answer:
Step-by-step explanation:
3(3z-6)=0
multiply your three with the 3z and the -6
9z-18=0
figure out what - 18 = 0
9z=18
9*2=18
z=2
hope this helps
im not the best at math but i think is would be something like 3ft
if you dont thinks its right explain in a lot more details :D
but if it helped ok :D
in a way it was a guess since the first i thought of was multiplication like 6x3=18

The slope-intercept form is y = m x + b y = m x + b , where m m is the slope and b b is the y-intercept. y = m x + b y = m x + b
Rewrite in slope-intercept form.
Subtract 3 x 3 x from both sides of the equation. − 8 y = 5- 3 x - 8 y = 5-3 x
Divide each term by −8 -8 and simplify. y = 3 x 8 − 58 y = 3 x 8 - 58
Rewrite in slope-intercept form. y = 38 x − 58 .
Answer:
5/2
Step-by-step explanation:
The x value is being multiplied by 5/2
and the slope is the value the x value is being multiplied by
so the slope is
5/2
Solve the equation using the quadratic formula ⇨ x² + 11x + 9 = 0
All equations of the form can be solved using the quadratic formula: . The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.
This equation is in standard form: ax² + bx + c = 0. Substitute 1 for a, 11 for b and 9 for c in the quadratic formula .
Square 11.
Multiply -4 times 9.
Add 121 to -36.
Now solve the equation when ± is plus. Add -11 to √85.
Now solve the equation when ± is minus. Subtract √85 from -11.
The equation is now solved. The solution set is :-
