x = number of months
7*x = 7 times the number of months
7*x = total cost if you ignore the $100 fee
7x+100 = total cost with the fee of $100 included
y = total cost
y = 7x+100
Final Answer: y = 7x+100
note: the slope is 7 and the y intercept is 100
Answer: Formula is y=Mx+b
Answer: Y=
Step-by-step explanation:
M=2
X=X
B=5
Y=Y
This is how all of these equations are set up.
Hope this helps.
Answer:
x = -4
Step-by-step explanation:
x+y = -10 or y = -10 - x
substitute this into the second equation
x - y = 2
x - (-10-x) = 2
2x + 10 = 2
2x = -8
x = - 4
Answer:
C. Add 9 to both sides of the equation.
Step-by-step explanation:
Given
Required
Complete the squares
We have:
---------------------------------------------
Take the coefficient of -6 i.e. -3
Square it (-3)^2 = 9
Add 9 to both sides
---------------------------------------------
<em>Hence, C is correct</em>
Answer:
x²+4=0
Step-by-step explanation:
x²=-4
√x² = √-4
x = 2i
x is an imaginary number
