Answer:
4x² + 18
Step-by-step explanation:
note that (c ○ d )(x) = c(d(x))
To evaluate substitute x = d(x) into c(x), that is
c(d(x))
= c(x² + 5)
= 4(x² + 5) - 2
= 4x² + 20 - 2
= 4x² + 18
Answer:
4:1
Step-by-step explanation:
There are 4 infielders and 1 battery
Because we are looking at money and amount there will be 2 sepret equations that can be solved using the Elimination or Substitution method.
$4,800=x18+y33 would be the first one that is dealing with money.
200=x+y
I personally find the substitution method easier but whatever you like could work. First things first, get Y alone in ONE equation, you can choose whatever one you want but I am going to use the bottom one cause it is the easiest.
200=x+y
-x -x subtract x from both sides
200-x=y. y is now alone making it easy to switch the equation
y=200-x this equation is the value of y
Now plug in the value of y in the top equation,
4,800=x18+33(200-x) now solve this equation
4,800=x18+6600-33x
4,800=-15x+6600
-6600. -6600
-2200=-15x. divide by -15
x=146.67
now since we have the x value we can plug it in to the bottom equation.
200=146.67+y
-146.67
y=53.33
these coordinates are the intersection point so it'll give ya the number.
hope this helped a little
If 3x + 8 = 18, then 2(3x + y) = 36
if x = 5, then 2x + 5 is 10 more then x
if x + y = 12, then 3x + 3y = 36
if 5.353 = 53k, then k = 0.101
if x = 3.6 and y = 6.4, then 100(x + y) = 1000
