Plug in the point (1,6) into the inequality 4x-3y<12 to determine if the point is in the solution set. How do you know
A Yes, (1,6) is in the solution set because the truth value is TRUE
B No, (1,6) is not the solution because the truth value is FALSE
Answer:
false
Step-by-step explanation:
4(1) - 3(6)<12
4 - 18<12
12<12
so no the truth value is false 12 is not less than 12
Answer:
A. true
Step-by-step explanation:
If you plug in x and y, the equation is 4(1)-3(6)<12. SImplify to get 4-18<12 which is equal to -14<12 which is true.

Solve for h.
h/10 + 5 = 25
so what’s h ??
Answer:
h=200
Step-by-step explanation:
h/10+5=25
h/10=20
h=200
h/10 + 5 = 25
Subtract 5 from each side to get h/10 alone.
h/10 + 5 - 5 = 25 - 5
h/10 = 20
Multiply both sides by 10 to get h alone.
h/10 • 10 = 20 • 10
h = 200
h = 200. I hope this helps!

Hakim received some gift cards for music and movie downloads for his birthday. Using one of them, he downloaded 20 songs and 13 movies, which cost a total of $163. Using another, he purchased 13 songs and 13 movies, which cost a total of $156. How much does each download cost?
Downloads cost $____for a song and $______ for a movie.
Answer:
the download cost for a song is $1 and $11 for a movie
Step-by-step explanation:
According to the questions, the following equations are as follows:
Let us assume the song be x
And, the movies be y
So,
20x + 13y = $163.........(i)
13x + 13y = $156........(ii)
Now solve substract second equation from the first equation
7x = $7
x = $1
And the y value is
20 + 13y = $163
13y = $163 - $20
13y = $143
y = $11
Hence, the download cost for a song is $1 and $11 for a movie

Answer:
[tex]y=\frac{1}{2}[/tex]
Step-by-step explanation:
[tex]4(y+1)= \frac{3}{1-y}[/tex]
[tex]4y+4= \frac{3}{1-y}[/tex]
[tex](4y+4)(1-y)= 3[/tex]
[tex]4y(1-y)+4(1-y)=3[/tex]
[tex]4y-4y^{2} +4-4y=3[/tex]
[tex]-4y^{2}=3-4[/tex]
[tex]4y^{2}=1[/tex]
[tex]y^{2} = \frac{1}{4}[/tex]
[tex]y=\sqrt{\frac{1}{4} }[/tex]
[tex]y=\frac{1}{2}[/tex]
