What is the formula for this equation?
Answer:
3x + 1/5y = 7
1/5y = 7 - 3x
y = 5 (7 - 3x)
y = 35 - 15x
Step-by-step explanation:
So it's best in this case to separate both shapes so you have a rectangle and a triangle so to solve the area of a rectangle you do
The following ( picture )
So I hope this helps
Answer:
-5
Step-by-step explanation:
or, f(x) = -x^2+10x+16
or, f(7) = (-7)^2+10*-7+16 (-7*-7=49)
=49-70+16
=65-70
=-5
