Answer:
f(7) = 16
Step-by-step explanation:
substitute x = 7 into f(x) , that is
f(7) = 3(7) - 5 = 21 - 5 = 16
Answer:
Step-by-step explanation:
Step 1: Subtract 10 from both sides.
2x2+20x−10=10−10
2x2+20x−10=0
For this equation: a=2, b=20, c=-10
2x2+20x+−10=0
Step 2: Use quadratic formula with a=2, b=20, c=-10.
x=
−b±√b2−4ac
2a
x=
−(20)±√(20)2−4(2)(−10)
2(2)
x=
−(20)±√(20)2−4(2)(−10)
2(2)
x=
−20±√480

x=−5+√30 or x=−5−√30
Answer:
x=−5+√30 or x=−5−√30
Answer:
i believe it would be $443.75
Step-by-step explanation:
just add 8.75 to 9.00 then multiply it by 25
8.75+9.00= 17.75 x 25= 443.75
if its a different type of equation then maybe this didn't help but i hope it does
