Answer:
multiplying by .06 will give you the amount of the increase , which you can add to the original price
to do it in one step , factor in 100% of the original price
the new price is 106% of the original
$85 * 1.06
Answer:
it's 2/3piX^3 i got a 100 on the test
Step-by-step explanation:
x = 36.2 .
______________________________________________
Explanation:
________________________________________________
2x - 1 + 3x = 180 ;
Combine the "like terms" on the left-hand side of the equation:
________________________________________________
+2x + 3x = + 5x ;
_____________________________________
And rewrite:
_____________________________________
5x - 1 = 180 ;
_____________________________________
Add "1" to each side of the equation:
_____________________________________
5x - 1 + 1 = 180 + 1 ;
_____________________________________
5x = 181 ;
_____________________________________
Divide EACH SIDE of the equation by "5" ;
_____________________________________
5x / 5 = 181 / 5 ;
_____________________________________
to get:
_____________________________________
x = 36.2 .
_____________________________________
The range is the output value or the y value.
You would work backwards to find the domain.
f(x) = 4x - 1 f(x) = 4x - 1
3 = 4x - 1 7 = 4x - 1
add 1 to both sides add 1 to both sides
4 = 4x 8 = 4x
divide both sides by 4 divide both sides by 4
x = 1 x = 2
f(x) = 4x - 1 f(x) = 4x - 1
11 = 4x - 1 15 = 4x - 1
add 1 to both sides add 1 to both sides
12 = 4x 16 = 4x
divide both sides by 4 divide both sides by 4
x = 3 x = 4
Domain { 1, 2, 3, 4}
