Answer:A= 7
Step-by-step explanation:
y=mx+b
512=114x+134
subtract 134 from both sides of the equation,
378=114x
Divide 144 from both sides of the equation to get x by itself
x=6.25
you'll round up because you can't really have a quarter day.
A= 7
Graphs of y = x+- 1 and of y = x - 1 are shown in the figure below.
The intersection of the two graphs is the solution for the two equations.
Answer:
There is no solution.
Explanation:
It is clear that the two lines are parallel and will never intersect.
Note that the equation for a straight line is of the form
y = mx + b
where
m = slope,
b = y-intercept.
y = x + 1 has slope of m=1.
y = x - 1 has slope of m=1.
The two slopes are equal.
Because parallel lines do not intercept, there is no solution.
Answer:
In this case, the equation that models the value of an initial investment of P dollars in t years at an annual interest rate of r is given by A = Pert.
Step-by-step explanation:
Answer: 42 units squared
Step-by-step explanation:
3x7=21
3x7=21 divided by 2 = 10.5 + 10.5 = 21 so,
21+21=42
