Answer:
y=90 when x=4
Step-by-step explanation:
We are given that
When x=8 and y=250
We have to find the value of y when x=4
Where k= Proportionality constant
Substitute the values
Now, substitute x=4 and k=5/2
Then, we get
Answer:
5x + 12
Step-by-step explanation:
simplify f(x) and g(x)
g(x) = 4*2 -3*2 +5
g(x) = 8 -6 + 5
g(x) = 7
and
f(x) = 4*2 + 5x -3
f(x) = 8 + 5x - 3
f(x) = 5x + 5
So (f + g)(x) = f(x) + g(x)
(f + g)(x) = (5x + 5) + (7)
(f + g)(x) = 5x + 12
Find the gradient so (-5-3)/(2+1) =-8/3 input it in y=mx+c and also use the coordinates from the question
So it becomes
3=-8/3 (-1) + c
C=1/3
Y=-8/3 x+1/3
