Answer:
yes, the point (-1, 5) is in the solution set
Step-by-step explanation:
y ≥ 2x + 3
Is 5 ≥ 2(-1) + 3? Yes
y + x > 0
Is 5 + (-1) > 0? Yes
Answer:
Yes the Point (-1,5) is in the solution set.
Step-by-step explanation:
Well you have to sub in the x and the y.
In the first equation
5 >= 2(-1) +3 = 5>= 1 So this one is true and in the set.
The second one
5+-1>0 = 4>0. So this one is also true.

Answer:
y = 30
z = 115
Step-by-step explanation:
z° + 65° = 180°
(Exterior Angles on the same side of transversal)
z° = 180° - 65°
z° = 115°
z = 115
(5y - 85)° + z° = 180°
(Linear pair angles)
(5y - 85)° + 115° = 180°
(5y - 85)° = 180° - 115°
(5y - 85)° = 65°
5y - 85 = 65
5y = 65 + 85
5y = 150
y = 150/5
y = 30

The perimeter of a square can be found using the formula P = 4s where s is the side length of the square. If you were to increase the length s by 11, the
expression for the perimeter would become 4/5 + 11). Expand the expression to represent the perimeter of the larger square.
Which expression represents the perimeter of the larger square?
O A. 4s +11
O B. 45 +44
O C. 5s + 15
O D. S +44
Answer:
Step-by-step explanation:
Are you scanning the question?—because there are some errors. If the length of a side is increased by 11, the expression for the perimeter would become
4(s+11)
not 4/5+11)
4(s+11) = 4s+44
The answer is B, which should read 4s+44, not 45+44
The perimeter of a square is 4s+44. So option (B) is the correct option.
What is the perimeter?The perimeter of a square is the total length of all the sides of the square. Hence we can find the perimeter of a square by adding all its four sides.
For the given situation,
The perimeter of the square is given by the formula, P = 4s
where, P is the perimeter and s is the side of the square
The length of the square is increased by [tex]11[/tex]
So, the perimeter becomes [tex]p=4(s+11)[/tex]
⇒[tex]p=4s+44[/tex]
Hence we can conclude that the correct option is (B) 4s+44.

two partners divide a profit of $2,000 so that's a difference between the two amounts is half of their average. what is the ratio of the larger to the smaller amount?
Answer:
5/3
Step-by-step explanation:
The partners have a total profit of $2000. Since there are only 2 partners, then the average profit each one makes is $2000/2 = $1000.
The difference between the 2 amounts is half of the average, so it is $1000/2 = $500.
One amount is x.
The other amount is x + 500
The sum is 2000
x + x + 500 = 2000
2x + 500 = 2000
2x = 1500
x = 750
x + 500 = 750 + 500 = 1250
The partners had profit of $1250 and $750.
The ratio is 1250/750 = 125/75 = 5/3
Answer: 5/3
The ratio of the larger to the smaller amount will be 5 : 3
What are ratios?
A ratio says how much of one thing there is compared to another thing. We can write the ratio as -
x : y
{x/y} = k
x = ky
[k] is called the scale factor.
Given is that two partners divide a profit of $2,000 so that's a difference between the two amounts is half of their average.
Assume that the amount with partner [1] is $[x] and with partner [2] is $[y]
. So, we can write according to the question as -
x + y = 2000 ......Eq [1]
x - y = {1/2 x (x + y)/2} ......Eq [2]
Now -
x - y = {1/2 x (2000/2)}
x - y = {1/2 x 1000}
x - y = 500
x = 500 + y
So, we can write the equation [1] as -
x + y = 2000
500 + y + y = 2000
2y = 1500
y = 750
So, [x] will be equivalent to -
x = 2000 - 750
x = 1250
The ratio of the larger to the smaller amount will be -
x/y = 1250/750 = 250/150 = 50/30 = 5/3
Therefore, the ratio of the larger to the smaller amount will be 5 : 3.

Step-by-step explanation:
The number that lies halfway between 16 and 38 is 27.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.
We have to determine the number that lies halfway between 16 and 38.
This is calculated by finding the average (or mean) of the two numbers. To do this, add the numbers together (16 + 38) and divide by 2.
⇒ 54/2
The result is 27.
Thus, the number that lies halfway between 16 and 38 is 27.

Step-by-step explanation:
Answer:
1 1/4 + 1 1/2 = 2 3/4
Step-by-step explanation:
first do 1/4 plus 1/2 to solve that you need the same denominator. To get the same denominator you have to see which number they both go into equally, 4 goes into 4 once and 2 goes into 4 twice, meaning you can make both denominators 4. 2 * 2 = 4 and if you do something to the denominator you have to do it to the numerator, so 1/2 would become 2/4. 1/4 plus 2/4 is 3/4. now move onto the whole numbers 1+1=2. so, the answer must be
