Points named by variables.
Answer:
x = 0
y= -3
Step-by-step explanation:
x = y + 3 into the equation y = -4x - 3, so
y = -4(y+3) - 3
y = -4y - 12 - 3
y = -4y - 15
5y = -15
y = -3
Then, you can substitute this into the equation x = y + 3
Answer:
b
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
let a = second month's revenue
5000 = a(1.3)
a = 5000 / 1.3 = 3846
Answer:
15
Step-by-step explanation:
So, leets look at the graph.
We can see that the lines being solved for tecnically make up 180 degrees.
This is because the value of the angles on line m are equal to the value of the angles on line n.
So, we know that the total line, 180 degrees, is 7x-10, and 6x-5.
Lets combine these two equations, and subtract them from 180 degrees to solve for x:
7x-1+6x-5
=
13x-15
Now to solve for x:
13x-15=180
Add 15 to both sides to get 13x alone:
13x=195
Then divide both sides by 13 to get x alone:
x=15
So our value of x is 15!
Hope this helps! :)
Since 0 isn't above 5 it will stay the same, So 2096 to the nearest thousand will be 2000
