The constant rate of change is 5 because
You set the corresponding sides equal to each other and solve for x as you would in a normal equation
y= -1/5x-4
explanation:
the rise over run is -1/5
the y-intercept is -4
The formula is
A=p (1+r/k)^kt
A future value?
P present value 240
R interest rate 0.09
K compounded monthly 12
T time 14 years
A=240×(1+0.09÷12)^(12×14)
A=842.13
Neither of the options are correct for the given equations.
Step-by-step explanation:
-x+y=4...................................................1
16x+y=-3...............................................2
Subtract equation 1 and 2
-x+y- 16x -y = 4+3
⇒ -17x = 7
⇒x=
⇒x= -0.4117
so,
16×-0.4417 + y = -3
⇒y= -3+6.5872
⇒y= 3.5872
So the point of intersection is (-0.4117, 3.5872)
