Answer:
this is a table
y= (a times when y is negative)
X=(X is possitive)
Answer:
Answer:
y=
d−4
/c+9
Step-by-step explanation:
cy+4=d−9y
Step 1: Add 9y to both sides.
cy+4+9y=d−9y+9y
cy+9y+4=d
Step 2: Add -4 to both sides.
cy+9y+4+−4=d+−4
cy+9y=d−4
Step 3: Factor out variable y.
y(c+9)=d−4
Step 4: Divide both sides by c+9.
y(c+9) c+9
=
d−4
/c+9
y=
d−4
/c+9
