Answer:
Except k=7, any real number for k would cause the system of equations to have no solution.
Step-by-step explanation:
In general a system of equations can be represented as ax+by=c and dx+ey=f. In order this system of equations to have NO SOLUTIONS a/d=b/a≠c/f. In our example a=6, b=4, c=14, d=3, e=2 and f=k. To apply the formula above, 6/3=4/2≠14/k. Hence k≠7. It can be concluded that except k=7, any real number for k would cause the system of equations to have no solutions.
Just for information, if k=7 the system will have infinitely many solutions.
Answer:
18
Step-by-step explanation:
10/0.5 = 20
20 * 0.9 = 18
Answer: x^2 + y^2 -10y = 0
Step-by-step explanation:
Cartesian coordinates, also called the Rectangular coordinates, isdefined in terms of x and y. So, for the problem θ has to be eliminated or converted using basic foundations that are described by the unit circle and the right triangle trigonometry.
r= 10sin(θ)
Remember that:
x= r × cos(θ)
y= r × sin(θ)
r^2= x^2 + y^2
Multiply both sides of the equation by r. This will give:
r × r = 10r × sin(θ)
r^2 = 10r × sin(θ)
x^2 + y^2= 10r × sin(θ)
Because y= r × sin(θ), we can make a substitution. This will be:
x^2 + y^2= 10y
x^2 + y^2 -10y = 0
The above equation is the Rectangular coordinate equivalent to the given equation.
Answer:
Follow along with the pattern, for example if it is going by 2's then you would write a 4
Answer:
y=250x+2000
Step-by-step explanation:
The farmer starts with 2000 trees and adds 250 each year.
Year 0 2000
Year 1 2000 + 250 = 2000+ 1(250)
Year 2 2000 + 250 +250 = 2000 + 2(250)
Year 3 2000 + 250 + 250 + 250 = 2000 + 3(250)
Year 4 2000 + 250 + 250 + 250 + 250 = 2000 + 4 (250)
.....
Year X 2000 + 250x
