Drag each inequality to the correct location on the table based on whether its
graph will have a dashed or a solid boundary line.
Answer:
y>2x+8: Dashed x+1/2y is less than or equal to 12: Solid y is greater than or equal to 2/3x-6: Solid -4x+2y<10: Dashed
Step-by-step explanation:
If there is a < or > sign, it is dashed, because the answer you get is not part of the solution (it is either less than or greater than the solution). If it is a less than or greater than or equal to sign (with the line under it) the line will be solid because the answer you get is part of the solution.
The boundary line will not be included in the solution set. Therefore, the boundary line will be dashed. The table shows the following:
Dashed if the boundary line is not included in the solution set.
Solid if the boundary line is included in the solution set.
The inequalities that will have a dashed boundary line are:
y > 2x + 5
x + y ≤ 12
The inequalities that will have a solid boundary line are:
y ≤ 2x - 6
-4x + 2y - 10 ≤ 0
Here is an explanation of why each inequality will have the boundary line that it does:
y > 2x + 5
This inequality is not equal to 2x + 5, so the boundary line will not be included in the solution set. Therefore, the boundary line will be dashed.
x + y ≤ 12
This inequality is equal to x + y ≤ 12, so the boundary line will be included in the solution set. Therefore, the boundary line will be solid.
y ≤ 2x - 6
This inequality is equal to y ≤ 2x - 6, so the boundary line will be included in the solution set. Therefore, the boundary line will be solid.
-4x + 2y - 10 ≤ 0
This inequality is not equal to -4x + 2y - 10, so the boundary line will not be included in the solution set. Therefore, the boundary line will be dashed.

When you flip a biased coin the probability of getting a tail is 0.2.
How many times would you expect to get tails if you flip the coin 240 times?
Answer:
48
Step-by-step explanation:
Multiply 0.2 × 240 = 48.
It's a very biased coin, so the outcome will be considerably less than the 120 we would expect from a fair coin.

find the value of X, please!
Answer:
x=42°
Step-by-step explanation:
We know that 2 of the legs are congruent, so the angles opposite them will be congruent.
The angles of a triangle add up to 180°
This can be represented by [tex]96+2x=180[/tex]
[tex]2x=84[/tex]
[tex]x=42[/tex]
Hope this helps :-)
Answer: 42 degrees
Step-by-step explanation: Since this is an isosceles triangle, your remaining two angles will be equal
There are 180 degrees in any triangle
Since you have already used 96 degrees, you must subtract to find what is remaining
180-96=84
Since your remaining two angles are equal, you can half 84 to find your answer
84/2=42
Both x and your one remaining angle should be 42
X=42

What is the smallest 3-digit number of the form aaa such that it is divisible by 9? (Here, a represents a digit.)
Answer:
If all three digits need to be the same (I assume that's what aaa means) it's 333
Step-by-step explanation:
For a number XYZ to be divisible by 9, X+Y+Z must be divisible by 9. Here's why:
X*100 + Y * 10 + Z = X + Y + Z + 99*X + 9*Y = X + Y + Z + 9(11X + Y)
So we need to find the smallest a so that a+a+a = 3a is divisible by 9. The smallest would be 0, but 000 is not a real 3-digit number. The next one is 3.

Kiran is playing a video game. He earns 3 stars for each easy level he completes and 5 stars for each difficult level he completes. He completes more than 20 levels total and earns 80 or more stars
Answer:
10 easy levels and 10 difficult levels
Step-by-step explanation:
Given data
let the number of easy levels be x
and the number of difficult levels be y
so
x+y= 20----------1
and
3x+5y= 80------2
from 1
x=20-y
put this in 2
3(20-y)+5y= 80
60-3y+5y=80
2y=80-60
2y=20
y= 20/2
y= 10
put y= 10 in 1
x+10=20
x=20-10
x= 10
Hence Kiran played 10 easy levels and 10 difficult levels

Giselle pays $210 in advance on her account at the athletic club. Each time she uses the club, $15 is deducted from the account. Model the situation with a linear function.
A. b = 195 – 15x
B. b = 210 – 15x
C. b = 195 + 15x
D. b = 210 + 15x
Answer:
B is correct. Your starting amount is 210$ And you're taking away 15$ each time she uses the club,x.
Step-by-step explanation:
Answer:
The linear function model the situation is b = 210 - 15x .
Option (B) is correct .
Step-by-step explanation:
Let us assume that the number of times giselle uses the club be x .
As given
giselle pays $210 in advance on her account at the athletic club.
Each time she uses the club,$15 is deducted from the account.
Let suppose that the money left after giselle uses the club x times is b .
Than the equation becomes
Money left = Amount pay in advance - Deducted amount × Number of times giselle uses the club .
Put all the values in the above
b = 210 - 15 × x
b = 210 - 15x
Therefore the linear function model the situation is b = 210 - 15x .
Option (B) is correct .
