Y varies directly with x, it is a direct relationship between the two.
We will build the equation in the form of y = mx + b where 'm' is the slope and 'b' is the y-intercept.
We know the slope and we know the where the line intercepts the y-axis.
The answer:
y = 1x + -1
Because the coefficient of "1x" is just one we can simplify to the final answer:
y = x + -1
Answer:
m = (50d) + (2p)
Step-by-step explanation:
p = phones
m= money
d = days worked.
50 is the standard
Answer:
5.19%
Step-by-step explanation:
The amount of an account (A) earning simple interest rate r for time t on principal P is ...
A = P(1 +rt)
Filling in the given values and solving for r gives ...
6000 = 5500(1 +r(21/12))
12/11 = 1 + r(7/4) . . . . . . . . . . divide by 5500, simplify fractions
1/11 = r(7/4) . . . . . . . . subtract 1
4/77 = r . . . . . . . . . . . multiply by 4/7
r ≈ 0.051948 ≈ 5.19%
You will be earning about 5.19% annual simple interest.
Answer:
Yes
Step-by-step explanation:
Substituting in x = -7, we get y = 6(-7) = -42, which is the same as the y coordinate of the given point.
