Jill earned $40 from a carpool plus $9 per hour (h) babysitting this week. Which of the following expressions best represents Jill's income for the week?
A 9 + 40h NEED HELP PLZ SOMEONE :(
B 9 + h + 40
C 9h + 40
D 9 + 40
Answers
Answer:
9h + 40
Step-by-step explanation:
Since Jill earns 9 dollars per hour, you multiply the amount of hours she works by the amount she makes per hour (9h), then you add 40 which is a set amount.
y = 9h + 40
(f + h)(x)
given f(x)= 3x-2x+4, g(x)= 8x-2, h(x)= 3x +2
Answers
Answer:
To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to.
(f + g)(x) = f (x) + g(x)
= [3x + 2] + [4 – 5x]
= 3x + 2 + 4 – 5x
= 3x – 5x + 2 + 4
= –2x + 6
(f – g)(x) = f (x) – g(x)
= [3x + 2] – [4 – 5x]
= 3x + 2 – 4 + 5x
= 3x + 5x + 2 – 4
= 8x – 2
(f × g)(x) = [f (x)][g(x)]
= (3x + 2)(4 – 5x)
= 12x + 8 – 15x2 – 10x
= –15x2 + 2x + 8
\left(\small{\dfrac{f}{g}}\right)(x) = \small{\dfrac{f(x)}{g(x)}}(
g
f

g(x)

My answer is the neat listing of each of my results, clearly labelled as to which is which.
( f + g ) (x) = –2x + 6
( f – g ) (x) = 8x – 2
( f × g ) (x) = –15x2 + 2x + 8

help meeeeeeeeeeeeeeeeeeeeeef(x) = 2x - 7. evaluate f(0.5)
Answers
Answer:
f(x)=-6
Step-by-step explanation:
f(0.5) means that x=0.5, so you substitute the x with .5 and multiply it times 2 which will get you 1. Then you subtract 7 to get -6.
Answer:
f(0.5)=-6
Step-by-step explanation:
f(x)=2x-7 f(0.5)
Just put in 0.5 for the x.
f(x)=2(0.5)-7
f(x)= 1 - 7
f(0.5) = -6

A bag with quarters and nickels contains 87 coins.The total amount is $7.35. How many quarter and nickels are in the bag
Answers
Answer: 72 nickels and 15 quarters
Step-by-step explanation:
72 times .05 = 3.6 or $3.60
15 times .25 = $3.75
Total = $7.35
.05 is representing the nickels and .25 is representing the quarters and if you take a calculator and do 87-72 you get 15 and you can set it up yourself to double check. But I wouldn't recommend doing it with pennies that's how I got confused so many times and you can also give yourself a similar problem if you want to make sure you know how to do it. Sorry if this was confusing.

Hello, can someone pls help me ty!
Answers
Answer:
C, 5/2
Step-by-step explanation:
3 I2x -1I + 4 = 16
Isolate absolute value:
3 I2x -1I + 4 - 4 = 16 - 4
3 I2x -1I= 12
(3 I2x -1I) / 3 = 12 / 3
I2x -1I= 4
Since the question is only asking for the positive, all you need to solve for is the +4. Solve for x
2x -1 = 4
2x -1 + 1 = 4 +1
2x = 5
2x / 2 = 5 / 2
x = 5/2 or C
A farmer has 48 feet of fence with which to make a corral. If he arranges it into a rectangle that is twice as
long as it is wide, what are the dimensions?
The shorter side is ?
feet while the longer side is ?
feet.
Answers
Answer:
The shorter side is 8 feet
the longer side is 16 feet
Step-by-step explanation:
lets call the shorter side x.
let's call the longer side 2x (because it's twice as long as the shorter side)
you know that the perimeter is 48 feet.
the perimeter would be 2(short side) + 2(long side)
using this, you can make the following equation:
2(x) + 2(2x) = 48
open the parenthesis.
2x + 4x = 48
6x = 48
x = 8
2x = 16

Tres aviones salen a la misma hora de un mismo aeropuerto, el primero sale cada 8 dias, el segundo cada 10 dias, y el tercero cada 20 dias. Si salen el 2 de enero, ¿cuales seran las fechas proximas en que volveran a salir juntos? ( el año es de 365 dias)
Answers
Responder:
Después de 40 días (11 de febrero)
Explicación paso a paso:
Dado que :
El avión 1 sale cada 8 días
El avión 2 sale cada 10 días
El avión 3 sale cada 20 días
Si todos se van el 2 de enero; La próxima fecha en que se irán juntos se puede obtener obteniendo el mínimo común múltiplo de los días de cada avión:
___8____10_____20
2 | _4____5______10
2 | _ 2____5______ 5
2 | _ 1 ____5______ 5
5 | _ 1 ____ 1 ______ 1
El mínimo común múltiplo es, por tanto;
2 * 2 * 2 * 5 = 40
Todos se irán juntos nuevamente después de 40 días:
(2 de enero + 40 días) = 11 de febrero
