Which ordered pairs are solutions to the inequality y - 3x < -8?
Select each correct answer.
(1, -5)
(-3, - 2)
(0, -9)
(2, -1)
(5, 4)
Answer:
The ordered pairs which are solution to given inequality are:
(0,-9)
(5,4)
Step-by-step explanation:
In order to check if the given ordered pairs are solution of the inequality or not we will put the ordered pairs one by one in the inequality.
If the inequality is holds true for the ordered pair, the ordered pair is the solution.
The inequality is:
[tex]y - 3x < -8[/tex]
So,
For (1,-5):
[tex]y - 3x < -8\\-5-3(1) < -8\\-5-3<-8\\-8<-8[/tex]
(1,-5) is not the solution of given inequality.
For (-3,-2):
[tex]-2 - 3(-3) < -8\\-2+9<-8\\7<-8[/tex]
(-3,-2) is not the solution of given inequality.
For (0,-9):
[tex]y - 3x < -8\\-9-3(0) < -8\\-9 <-8[/tex]
(0,-9) is the solution of the given inequality.
For (2,-1):
[tex]y - 3x < -8[/tex]
[tex]-1 - 3(2) < -8\\-1-3<-8\\-4<-8[/tex]
(2,-1) is not the solution of given inequality
For (5,4):
[tex]y - 3x < -8\\4 - 3(5) < -8\\4-15<-8\\-11<-8[/tex]
(5,4) is the solution of given inequality.
Hence,
The ordered pairs which are solution to given inequality are:
(0,-9)

Plz help and only give the answer! will mark brainliest! TY if u answer
A)The gallons of gas needed to make 320 miles = 24 gallons of gas
Explanation
Step 1: To find the gallons of gas needed to make 1mile
The car uses 15 gallons of gas to make 200 miles.
from this we get,
gallons of gas needed to make 1mile = 15/200 =3/40
Step 2: To find the gallons of gas needed to make 320 miles
Therefore, the gallons of gas needed to make 320 miles = 320 x(3/40) = 24 gallons of gas

Which of the following polynomial functions is graphed below?
Answer: B. f(x)=(x+4)(x-2)^2(x+3)
Step-by-step explanation:
in the graph there's two negative x value and one positive x value
so the function should be in a form of f(x)= (x+a) (x-b)^2 (x+c)
the one with negative value has a square, (x-b)^{2}, because that's where the y = 0 (the point is hitting the (x,0))

0.2x+2.7x−8.1=6.9+1.1x
The answer is not x = 83 tho
and don't do it for the points
0.2x + 2.7x - 8.1 = 6.9 + 1.1x
Combine like terms on left side:
0.2x + 2.7x = 2.9x
Now you have:
2.9x -8.1 = 6.9 + 1.1x
Subtract 1.1x from both sides:
1.8x - 8.1 = 6.9
Add 8.1 to both sides:
1.8x = 15
Divide both sides by 1.8:
X = 8.3333 ( round as needed) or as a fraction = 8 and 1/3
Answer:
8.3recurring
Explanation:
0.2x+2.7x =2.9x
rewrite the questions
2.9x-8.1=6.9+1.1x
like terms together. Therefore:
2.9x-1.1x = 1.8x
8.1 will go to the other side of the equal sign. Therefore:
8.1+6.9 = 15
Therefore: 1.8x = 15
x =15/1.8 which is equal to 8.3recurring

There are 28 red pens and 84 black pens in a bag.
Write down the ratio of the number of red pens to the number of black pens.
Give your ratio in its simplest form.
Answer:
1/3
Step-by-step explanation:
The ratio can be written as a fraction. This would be 28/84. You simplify ratios just like how you simplify a fraction. 28x3 is actually 84, so the answer in simplest form is 1/3.
Hope this helps and have a great day!! []~(^▽^)~*
The ratio of the number of red pens to the number of black pens in simplest form is, 1 : 3.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
We have to given that;
There are 28 red pens and 84 black pens in a bag.
Here, Number of red pens = 28
And, Number of black pens = 84
Hence, The ratio of the number of red pens to the number of black pens is,
⇒ Number of red pens : Number of black pens
⇒ 28 : 84
⇒ 28/84
⇒ 14 / 42
⇒ 1 / 3
⇒ 1 : 3
