<em>-7 -5 / 4 -2 / -12/2 </em>
<em>-12/2 = -6 </em>
<em>Slope: -6x </em>
<em>5 = 2(-6) + b</em>
<em>5 = -12 + b </em>
<em>-12 + 17 = 5 </em>
<em>Slope intercept Form: y = -6x + 17</em>
Z is inversely proportional to X is the same as
z is directly proportional to 1/X
which can be written like this:-
y=k/X
________
0.5=k/6
0.5*6=k/6*6
k=3 ;
________
z = 3/14
Z = 0.2
Answer:
Option 2: (1, 0) and (0, -5)
Step-by-step explanation:
Let's solve this system of equations using the elimination method.
Start by labelling the two equations.
5x -y= 5 -----(1)
5x² -y= 5 -----(2)
(2) -(1):
5x² -y -(5x -y)= 5 -5
Expand:
5x² -y -5x +y= 0
5x² -5x= 0
Factorise:
5x(x -1)= 0
5x= 0 or x -1= 0
x= 0 or x= 1
Now that we have found the x values, we can substitute them into either equations to solve for y.
Substitute into (1):
5(0) -y= 5 or 5(1) -y= 5
0 -y= 5 or -y= 5 -5
y= -5 or -y= 0
y= 0
Thus, the solutions are (0, -5) and (1, 0).
Y-y1=m(x-x1)
y-5=10(x-1)
Y-5=10x-10
Y=10x-5
