Answer:
x > -22/7
Step-by-step explanation:
To find out which inequality is is equivalent, you solve for x.
-4(x+7) < 3(x-2): distribute variables
-4x-28 < 3x-6: Add 6 to both sided
-4x-22 < 3x: add 4x to both sides
-22 < 7x: divide by 7
-22/7 < x: you can switch sides if prefered but you have to switch sign too
x > -22/7

Adrian is a songwriter who collects royalties on his songs whenever they are played in a commercial or movie. Adrian will earn $40 every time one of his songs is played in a commercial and he will earn $130 every time one of his songs is played in a movie. Adrian earned a total of $1010 in royalties on 14 commercials and movies. How many commercials and movies did Adrian's songs play on?
Answer:
Adrian's songs played on 9 commercials and 5 movies.
Step-by-step explanation:
Let x denotes number of commercials and y denotes number of movies.
Total number of commercials and movies = 14
So,
[tex]x+y=14\\x=14-y\,\,\,\,...(i)[/tex]
Adrian will earn $40 every time one of his songs is played in a commercial and he will earn $130 every time one of his songs is played in a movie
Total amount earned = $1010
[tex]40x+130y=1010\,\,\,...(ii)[/tex]
Put [tex]x=14-y[/tex] in (ii)
[tex]40(14-y)+130y=1010\\560-40y+130y=1010\\90y=1010-560\\90y=450\\y=\frac{450}{90}=5[/tex]
Put [tex]y=5[/tex] in [tex]x=14-y[/tex]
[tex]x=14-5=9[/tex]
Therefore, Adrian's songs played on 9 commercials and 5 movies.

What is a function Inverse
Answer:
an inverse function (or anti-function) is a function that "reverses" another function
Step-by-step explanation:
Answer:
an inverse function is a function that "reverses" another function: if the function f applied to an input x gives a result of y, then applying its inverse function g to y gives the result x, and vice versa, i.e., f(x) = y if and only if g = x.
Write an equivalent expression for (3m - 6)(8m2 - 40m - 5).
Answer:
24m3−168m2+225m+30
Step-by-step explanation:
(3m+−6)(8m2+−40m+−5)
=(3m)(8m2)+(3m)(−40m)+(3m)(−5)+(−6)(8m2)+(−6)(−40m)+(−6)(−5)
=24m3−120m2−15m−48m2+240m+30

Una empresa comercial vende automóviles cuyo precio es de S/. 60 000, con una cuota inicial del 20%, para cancelar el saldo en 30 meses de plazo.calcula la cuota fija mensual que se pagará seda empresa cobra una tasa de interés simple del 12% semestralmente
Responder:
2560
Explicación paso a paso:
Dado lo siguiente:
Precio del automóvil = 60000
Cuota inicial = 20% del precio = (0.2 * 60000 = 12,000
Saldo = (60000 - 12000) = 48000
La empresa cobra un interés simple del 12% cada 6 meses
Periodo de pago = 30 meses / 6 = 5 periodos
Interés simple: p * r * t
= 48000 * 0,12 * 5 = 28800
Por lo tanto, monto total a reembolsar, incluidos los intereses:
Balance + 28800; 48000 + 28800 = 76800
El reembolso mensual es fijo;
Por lo tanto,
76800/30 = 2560
Finding the Slope of a Line from a Table
What is the slope of the linear function represented in
the table?
y
o
.
Answer:
m = rise / run = 1/7
Step-by-step explanation:
Recall that the slope of a line is m = rise / run.
Here we look at x first (to calculate the run): x begins at -7 and ends at 0. Thus, the run is 0 - (-7), or 7.
Now look at how y behaves (find the rise): y begins at 0 and ends at 1. Thus, the rise is 1.
Therefore the slope of the line connecting the two poings given is
m = rise / run = 1/7
wut is the soulotion to this eqation2x+10=28
Answer:
x=9
Step-by-step explanation:
Step 1: Subtract 10 from both sides.
2x+10−10=28−10
2x=18
Step 2: Divide both sides by 2.
2x /2 = 18 /2

A number x plus 36 is no more than 40. Write this sentence as an inequality
Answer:
When we say 'as many as' or 'no more than', we mean 'less than or equal to' which means that a could be less than b or equal to b. But, when we say 'at least', we mean 'greater than or equal to'. Here a could be greater than b or equal to b.
