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.

pasagot po tnx
I will mark you as brainliest if your answer is good :3
Answer:
416.50 pesos
Step-by-step explanation:
Given
Represent the bread with b.
Mayonnaise with m
Ham with h
[tex]Amount\ Paid = 1000[/tex]
Required
Determine the change
From the question: a loaf costs 22.50
This is represented as:
[tex]b = 22.50[/tex]
5 loaves will be:
[tex]5*b = 22.50*5[/tex]
[tex]5b = 112.50[/tex]
A bottle of Mayonnaise costs 55.50
This is represented as:
[tex]m = 55.50[/tex]
2 bottles will be:
[tex]2*m = 55.50*2[/tex]
[tex]2m = 111[/tex]
Lastly,
1kg of ham costs 240
This is represented as:
[tex]h =240[/tex]
1.5kg will be:
[tex]1.5*h =240*1.5[/tex]
[tex]1.5h =360[/tex]
The cost of the items is:
[tex]Costs = 5b + 2m + 1.5h[/tex]
This gives:
[tex]Costs = 112.50 + 111 + 360[/tex]
[tex]Costs =583.50[/tex]
Her change is calculated as:
[tex]Change = Amount\ Paid- Cost[/tex]
[tex]Change = 1000 - 583.50[/tex]
[tex]Change = 416.50[/tex]

b) cos25
c = 7.248 or 7.2
Step-by-step explanation:
Cosine = [tex]\frac{adjacent}{hypothenuse}[/tex]
Cos 25 = [tex]\frac{8}{c}[/tex]
Cos of 25 is 0.906
0.906 = [tex]\frac{8}{c}[/tex]

the population of alaska is approximately 6.5 * 10^(5) people the populatio of illinois's is about 1.3 * 10^(7)people. how many times greater is the population of Illinois in the population of Alaska
Answer:
20 times greater
Step-by-step explanation:
Given the following
Population of alaska = 6.5 * 10^(5) people
Population of illinois's = 1.3 * 10^(7)people.
To know the number of times population of Illinois in the population of Alaska, we will take their population ratio;
Ratio = Population of illinois's /Population of alaska
Ratio = 1.3 * 10^(7)/6.5 * 10^(5)
Ratio = 0.2 * 10^7-5
Ratio = 0.2 * 10^2
Ratio = 20
Hence the population of Illinois is 20 times greater than population of alaska

The function f ( x ) = 2 x ^2 − x − 4 models the shape of a ditch. What is the average slope over the interval −4 ≤ x ≤ 2?
Answer:
[tex]Rate = -5[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2x^2 - x - 4[/tex]
[tex]-4 \le x \le 2[/tex]
Required
Determine the average slope over the given interval
This is calculated as:
[tex]Rate= \frac{f(b) - f(a)}{b - a}[/tex]
Where:
[tex]a = -4[/tex]
[tex]b =2[/tex]
So:
[tex]Rate= \frac{f(2) - f(-4)}{2 - (-4)}[/tex]
[tex]Rate= \frac{f(2) - f(-4)}{2 +4}[/tex]
[tex]Rate= \frac{f(2) - f(-4)}{6}[/tex]
Solving for f(2) and f(-4), we have:
[tex]f(x) = 2x^2 - x - 4[/tex]
[tex]f(2) = 2 *2^2 -2 - 4[/tex]
[tex]f(2) = 2[/tex]
[tex]f(-4) = 2*(-4)^2 - (-4) - 4[/tex]
[tex]f(-4) = 2*16 +4 - 4[/tex]
[tex]f(-4) = 32[/tex]
So, the equation becomes
[tex]Rate= \frac{f(2) - f(-4)}{6}[/tex]
[tex]Rate= \frac{2 - 32}{6}[/tex]
[tex]Rate= \frac{-30}{6}[/tex]
[tex]Rate = -5[/tex]

Solve systems using Elimination
Answer:
y = 1.5, x = [tex]1\frac{12}{13}[/tex]
Step-by-step explanation:
The given simultaneous equation system is;
-1 - 2·y = -4...(1)
13·x + 2·y = 28...(2)
By elimination method, we have;
From equation (1);
-1 - 2·y = -4
2·y = 4 - 1 = 3
y = 3/2 = 1.5
y = 1.5
We eliminate 'y' from equation (2) by replacing the value of 'y' with 1.5 as follows;
13·x + 2·y = 28
y = 1.5
∴ 13·x + 2 × 1.5 = 28
13·x = 28 - 3 = 25
x = 25/13 = [tex]1\frac{12}{13}[/tex] = [tex]1.\overline{923076}[/tex]
x = [tex]1\frac{12}{13}[/tex]

A colony of 36,000 bacteria grows continuously at a rate of 12%. How many bacteria will there be in 2 years?
Answer:
45158
Step-by-step explanation:
Since the colony grows at a rate of 12%, after 2 years there will be [tex]36000\cdot 1.12^2 = 45158.4[/tex] bacteria. Since you probably can't have part of a bacteria, you round to 45158.
Answer:
45158
Step-by-step explanation:
Since the colony grows at a rate of 12°/• , after 2 years there will be 36000.
1.12 power of 2 = 45158.4 bacteria.
And you cant have part of a bacteria
you round it to
45158.
