Answer:
y = -2x + 25
Step-by-step explanation:
A standard equation can be in slope-intercept form: y = mx + b
m is the slope, b is the y-intercept.
Plug in the given slope.
y = -2x + b
To find b, plug in the given point (9, 7).
7 = -2(9) + b
Multiply.
7 = -18 + b
Add 18 to both sides to find b.
25 = b
Plug this into your standard equation.
y = -2x + 25
Check by plugging in the given point again.
7 = -2(9) + 25
7 = -18 + 25
7 = 7
Your answer is correct!
Hope this helps!
21.20 would be the total with tax
the taxes would equal $1.20
Honestly to explain it I put it into a calculator.. sorry :)
I put in 6% of 20 then add it to the $20
There will only be one solution to this problem.
220 = 2x - 12x
Combine like terms on the right side of the equation:
220 = - 10x
Divide both sides by - 10 to isolate the variable x.
220 / - 10 = x
-22 = x, one solution.
I’m not sure on how to do that
Answer:
19/6n - 7/2
Step-by-step explanation:
4n - 5/6n - 4 + 1/2
4 = 24/6
24/6 - 5/6
19/6
-4 = -8/2
-8/2 + 1/2
-7/2
19/6n - 7/2
