Answer:
D.
Step-by-step explanation:
the suggested relation can be described as y=15x. Then the correct answer is D) Yes, the points are on the line that passes through the origin.
I think the answer is the second one
Answer:
An equation that can be used to model these data is of the form: y = A cos B(x - C) + D,
where A,B,C,D, are constants, y is the temperature in °C and x is the month (1–12).
Eliminate one variable at a time. We have three equations so we can solve for three variables.
(5x-y+z=4)-5(x+2y-z=5)=-11y+6z=-21
-2(x+2y-z=5)+(2x+3y-3z=5)=-y-z=-5
Now using the two yz equations above to cancel out z
(-11y+6z=-21)+6(-y-z=-5)=-17y=-51
-17y=-51 divide both sides by -17
y=3, making -y-z=-5 become:
-3-z=-5, z=2, making <span>5x-y+z=4 become:
5x-3+2=4
5x-1=4
5x=5
x=1
So the solution to the system of equations, (x,y,z) is (1,3,2)</span>
