Answer:
x = -3, y = 5
Step-by-step explanation:
first, take the 3x + 17 = y and put it in place for the y in the second equation.
-3x=4x+17+4
then, solve the equation.
-3x=4x+21
-3x-4x=4x-4x+21
-7x=21
-7/-7x=21/-7
x = -3
substitute in other equation
4(-3) + 17 = y
-12 + 17 = y
y = 5
answers are x = -3 and y = 5
so these two lines intersect at x = 3 hmmmm what's the y-coordinate of the second line at that point?
so the y-coordinate of that second line is 0, so the point there is (3, 0) then.
so the first line is, a line that has a slope of 2 and passes through (3, 0).
Answer:
$19,950,000
Step-by-step explanation:
From the question, Value of a year of Life =$7,000,000
And Number of Years Left = 3 years
Then Total Value of Life left = Value Per Year X Number of Years Left
=$7,000,000 X 3
=$21,000,000
Note that a discount is the reduction in the actual value of a quantity by a certain amount or percentage.
If there is a discount of 5%.
5% of Total Life Value = (5/100) X 21000000
=0.05 X 21000000
= 1,050,000
Therefore :Value of Life = Actual Value - Discount Value
= 21000000-1050000
= $19,950,000
The answer to your math equation is
X=6/5 - 4y/5
Answer:
a)
In which 45300 is the current number of miles driven and 143 is the amount of miles she drives each day.
b) 47,016 miles.
Step-by-step explanation:
Question a:
Every day when commuting to and from work, Stefanie drives her car a total of 143 miles for 2.5 hours. Her car already has 45,300 miles on it.
So, after x days of work, the amount of miles driven will be given by
In which 45300 is the current number of miles driven and 143 is the amount of miles she drives each day.
Question b:
After 4*3 = 12 days of work. So
47,016 miles.
