The slope is 9/3 which can be simplified into 3/1
Answer:
f(g(5)) = 16.5
Step-by-step explanation:
To calculate f(g(5)), evaluate g(5) then substitute the value obtained into f(x)
g(5) =
× 5 = 2.5 , then
f(2.5) = 5(2.5) + 4 = 12.5 + 4 = 16.5
Answer:
y= 
Step-by-step explanation:
2x+3y=C
isolate y
3y=C-2x
y= 
Answer:
x>-23/7
Step-by-step explanation:
-23<7x
7x>-23
x>-23/7
the answer is x>-23/7
Ok so we know that y=1 so we can simply sub in the value of y into the equation :
y = -5x +3
1 = -5x +3
Move the -5x to the LHS ( Left-hand-side ) therefore it changes sign as well move 1 to the RHS ( Right-hand-side ) it also changes sign.
5x = 3 - 1
5x = 2
x = 2/5
x = 0.4
Hope this helps :).
