-9=-3(x+2)+5x what does x equal
Exact Form:
x=-3/2
Decimal Form:
x=−1.5x
Mixed Number Form:
x=−1 1/2
Answer:
-1.5
Step-by-step explanation:
-9=-3(x+2)+5x (switching the sides of the formula can make it easier)
-3(x+2)+5x=-9
2x-6=-9
add 6 to both sides ---> 2x-6+6=-9+6
simplify ----> 2x=-3
divide both sides by 2 ---> 2x/2 = -3/2
simplify ---> x= -3/2
decimal form- -1.5

how to interpret the meaning of a slope

Answer:
The number of tickets and cost have a proportional relationship.
Step-by-step explanation:
The points on the graph would be (2,36) , (5,90) , (9,162)
Graph the lines to see if the 'lines' are straight or not.
36/2 = 18
90/5 = 18
162/9 = 18
You can just this to check, as you can see, the rate of change stayed the same, so it is linear and proportional (straight line). Constant of proportionality means that between any 2 points on a line, they will have the same rate of change (aka. slope).
* * *
I don't want to confused anyone so I'll use this chance to explain the difference between linear and proportional.
In simple terms, proportional relationships has the y-intercept at 0. So proportional lines cross the origin (0,0) while linear lines just has to be a straight.
Hope I was able to help! Good Luck!

whats bigger 4/9 or 6/7
Answer:
[tex]\frac{6}{7}[/tex]
Step-by-step explanation:
[tex]\frac{4}{9}or \frac{6}{7}[/tex]
First you need to find a common denominator. so you could just multiply 9 and 7 or you could write the factors of each number.9*7 is 63, so that is your denominator. Multiply top and bottom of [tex]\frac{4}{9}[/tex] by 7 and you should get [tex]\frac{28}{63}[/tex].Multiply top and bottom of [tex]\frac{6}{7}[/tex] by 9 and you should get [tex]\frac{54}{63}[/tex]. Is [tex]\frac{28}{63}[/tex] or [tex]\frac{54}{63}[/tex] bigger?[tex]\frac{54}{63}[/tex] is bigger so your answer would be [tex]\frac{6}{7}[/tex].Hope this helps :)

The winning candidate in an election receives 0.58 of the votes. There are 1000 voters. How many votes does the winning candidate receive?
The winning candidate in an election receives 0.58 of the votes. There are 1000 voters. The winning candidate receives the votes is 580.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
The winning candidate in an election receives 0.58 of the votes.
There are 1000 voters.
58% of 1000
= 0.58 x 1000
= 580

Inequality
Jake is younger then Sophie
Sophie is 14 years old
_______________________
When it comes to inequality, we need to base if off of greater, less, or equal to. We know that Jake is younger than Sophie, therefore he is less in age, meaning that the less than symbol (<) will be used. Since Sophie is 14, he has to be less than 14. Therefore :
j < 14
