Find one point that lies in the solution set of the following system of inequalities:Y<(or equal)1/2x+6
y>-3x-1

justify answer

Answers

Answer 1
Answer: Simplify the first inequality.

Multiply 1/2 by x to get (1/2)x. 
y≤(1/2)x+6 and y>−3x−1 

Simplify. 
y≤x/2+6 and y>−3x−1

Since x is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation. 
x/2+6≥y and y>−3x−1 

Because 
6 does not contain the variable to solve for, move it to the right-hand side of the inequality by subtracting 6from both sides. 
x/2≥−6+y and y>−3x−1 

Multiply both sides of the equation by 2. 
x≥−6⋅(2)+y⋅(2) and y>−3x−1 

Multiply −6 by 2 to get −12. 
x≥−12+y⋅(2) and y>−3x−1 

Multiply y by 2 to get y(2). 
x≥−12+y(2) and y>−3x−1 

Multiply y by 2 to get y⋅2. 
x≥−12+y⋅2 and y>−3x−1 

Move 2 to the left of the expression y⋅2. 
x≥−12+2⋅y and y>−3x−1 

Multiply 2 by y to get 2y. 
x≥−12+2y and y>−3x−1 

Reorder −12 and 2y. 
x≥2y−12 and y>−3x−1 



Simplify the second inequality.

Because x is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation. 
x≥2y−12 and −3x−1<y 

Since −1 does not contain the variable to solve for, move it to the right-hand side of the inequality by adding 1 to both sides. 
x≥2y−12 and −3x<1+y 

Divide each term in the inequality by −3. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign. 
x≥2y−12 and 3x/−3>1/−3+y/−3 

Cancel 3 in the numerator and denominator. 
x≥2y−12 and −(−1⋅x)>1/−3+y/−3 

Multiply −1 by x to get −1x. 
x≥2y−12 and −(−1x)>1/−3+y/−3 

Rewrite −1x as −x. 
x≥2y−12 and −(−x)>1/−3+y/−3 

Simplify
x≥2y−12 and x>−1/3+y/−3 


x≥2y−12 and x>−1/3y/3 


Point of intersection: (-2, 5)

Answer: 1 hour

Step-by-step explanation:

1st trip = 4mph

12 mi / 4 mi

12 mi = 3 hrs

2nd trip = 6 mph

12 mi / 6 mi

12 mi = 2 hrs

3hrs - 2 hrs = 1 hr

A digital camera for $249.99 at 4% sales tax

Answers

First, change the 4% into a decimal. Once thats changed, it will be 1.04
Multiply 1.04 by the amount of the cost, to get your answer.
But, to make this easier, and to not go through more work, lets round your money amount to $250
Now, all you have to do is multiply.
$250 · 1.04 ≈ $260
So, your answer for $250 with 4% (1.04) percent sales tax would be a grand total of:
$260
~~~~~~~~~~~~~~
-Hope this helped :)
i'll round the 249.99 to 250 for simplicity 
250*1.04=260 or 259.9975 if you want to be technical

What median of this set 6,8,10,8,4,2,12

Answers

8 is the median. If yo line up the numbers from least to greatest you will get 2,4,6,8,8,10,12 and the middle number is 8.

well this is how you can find the median : To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

If there is an odd number of numbers, this middle number is the median.

now arrange this set of odd no.s in ascending order

we get , 2,4,6,8,8,10,12

in this the middle number is 8 so 8 is the median

The actual length of c in the triangle shown is 15 cm. Use the scale drawing of the triangle to find the actual length of side a.

Answers

Answer: 9.375 cm

Step-by-step explanation:

From the given picture, it can be seen that the measure of side 'c' in triangle = 1.92 cm

The actual length of 'c' in the triangle = 15 cm.

The scale factor =k=\frac{\text{ actual length of c}}{\text{length of c in figure}}

k=(15)/(1.92)=7.8125

Now, the length of side 'a' = 1.2 cm

The actual length of side 'a' k*1.2=7.8125*1.2=9.375\text{ cm}

We can solve this problem by the rule of three:

1.5 cm---------------15 cm
1.2 cm---------------  x

x=(1.2 cm*15 cm) / 1.5 cm=12 cm.

answer. a=12 cm.
