Tell whether the ordered pair a solution of the given system.
(1,3); {y <_ x+2
y >4x-1 }
Answer:
The ordered pair is not a solution to the given system of inequalities
Step-by-step explanation:
Here, we want to check if the ordered pair is a solution to the system of inequalities
Simply substitute 1 for x and y for 3
3 ≤ 1 + 2
3 ≤ 3
This is valid as 3 is equal to 3
secondly;
3 > 4(1) - 1
This does not work as
3 is not greater than 3

A store sells rope by the meter. The equation p=0.8L represents the price p (in dollars) of a piece of nylon rope that is L meters long. How long is a piece of nylon rope that costs $1.00? Use decimal notation.
Answer:
(a) $0.80
(b) 1.25 m
Step-by-step explanation:
(a) Put 1 where L is, and evaluate the equation.
... p = 0.8·1 = 0.8
The cost for 1 meter of rope is $0.80.
(b) Put 1 where p is and solve for L.
... 1 = 0.8L
... 1/0.8 = L = 1.25
The length of rope that costs $1 is 1.25 meters.

a restaurant sold 6 pies every day for a week if the cost of each buy is $1,250 how much did they make from pies for the week how much would they make in four weeks?
Answer:
Each pie is $1250
Everyday sell 6 pies,so one week sell:6×7=42
So total amount earned from selling pies for a week is 42×$1250=$52500
In 4 weeks=4×$52 500=$210 000

Answer:
The domain is the set of all integers from 0 to 14
The range is the set of all multiples of 5 between 0 and 70
Step-by-step explanation:
Domain and Range of a Function
The Domain of a Function is the set of values the input variable x takes.
The Range of a Function is the set of values the function takes when x moves into the function's domain.
Coach Harper can buy softballs at $5 each but he has a limit of $72 to spend on them. This situation is written as the following inequality:
5x ≤ 72
Where x is the number of softballs coach Harper can buy. Solving:
x ≤ 72/5
x ≤ 14.4
Since the number of balls must be an integer quantity and cannot be negative:
0 ≤ x ≤ 14
This means the maximum number of softballs coach Harper can buy is 14.
Thus, the domain is the set of all integers from 0 to 14
When 0 balls are bought, $0 are spent
When 1 ball is bought, $5 are spent
When 2 balls are bought, $10 are spent
Following that sequence with the maximum number of softballs:
When 14 balls are bought, $70 are spent
Note the cost can only be a multiple of 5 between 0 and 70, thus the range is the set of all multiples of 5 between 0 and 70.

You are decorating a rectangular table to surprise your friend with a party. The table is 4 feet by 10 feet. If you want to place a balloon in each corner and every 2 feet along the table, how many balloons will you need?
A. guess, check and revise
B. make a model or diagram
C. write an equation
D. make a table, chart or lis
SOME HELP PLZZZZ
Answer:
C. write an equation
Step-by-step explanation:
The best method would be to write an equation to solve this problem. This would be the best option because you are given all of the values/measurements of the table and the distance between balloons. Therefore, you would simply need to create an equation that calculates the perimeter of the table and divides a variable number of balloons 2 feet apart along the perimeter. Guessing is not a valid solution, especially when you are given actual data. Tables, Charts, and Lists are mainly used for large sets of data.

A paint store sells EXTERIOR paint for $36.25 a gallon and paint rollers for $7.50 each write an equation in standard form for the number of gallons P of paint and rollers r that a customer goodbye was $185
Answer:
$185 = ($35.25 * P) + ($7.50 * r)
Step-by-step explanation:
If the total that the customer paid was $185 this means that the equation must equal $185. The equation itself must be the number of gallons of exterior paint (P) that the customer ordered multiplied by the price per gallon ($36.25), which is then added to the product of the number of rollers the customer ordered (r) and the price per roller ($7.50). This together would form the following equation...
$185 = ($35.25 * P) + ($7.50 * r)

least common denomiator of 7/9 and 11/6
9514 1404 393
Answer:
18
Step-by-step explanation:
The least common denominator (LCD) is the least common multiple (LCM) of the denominators.
Here, the denominators are ...
9 = 3·3
6 = 3·2
So, their LCM is 3·3·2 = 18.
The least common denominator of the given fractions is 18.

7/9 = 14/18
11/6 = 33/18
Find the product of -2 x ( x^2 - 3)

-2x³+6x
Step-by-step explanation:
-2x(x²-3)
-2x³+6x
Answer: [tex]-2x^{3} + 6x[/tex]
Step-by-step explanation:
Find the Product
−2x ( [tex]x^{2}[/tex] − 3)
Apply the distributive property.
−2x ⋅ [tex]x^{2}[/tex] − 2x ⋅ −3
Multiply x by [tex]x^{2}[/tex] by adding the exponents.
−2 ( [tex]x^{2}[/tex]x ) − 2x ⋅ −3
Multiply [tex]x^{2}[/tex] by x.
Raise x to the power of 1.
−2 ( [tex]x^{2}[/tex] [tex]x^{1}[/tex] ) − 2x ⋅ −3
Use the power rule [tex]a^{m} a^{n} =a^{m+n}[/tex] to combine exponents.
[tex]- 2x^{2+1}[/tex] − 2x ⋅ −3
Add 2 and 1.
[tex]- 2x^{3}[/tex]− 2x ⋅ −3
Multiply −3 by −2.
[tex]-2x^{3}[/tex]+ 6x

Answer:
Use Plumber B since he charges $215, $10 less than Plumber A.
Step-by-step explanation:
Let y = total cost, and x = number of hours.
Plumber A:
y = 50x + 25
For a 4-hour call, x = 4.
y = 50(4) + 25
y = 200 + 25
y = 225
Plumber A charges $225 for a 4-hour call.
Plumber B:
y = 35x + 45
For a 4-hour call, x = 4.
y = 45(4) + 35
y = 180 + 35
y = 215
Plumber B charges $215 for a 4-hour call.
Answer: Use Plumber B since he charges $215, $10 less than Plumber A.
which angle has its terminal side on the positive y- axis?
A. 2pi radians
B. pi radians
C. pi/2 radians
D. 3pi/2 radians
Answer:
C. pi/2 radians
Step-by-step explanation:
other guy was right
[tex]\rm \frac{PI}{2}[/tex] Is the angle has its terminal side on the positive y-axis. Option C is correct.
What is the reference angle?The angle between the terminal side of the angle and the x-axis is called as the reference angle.
From the given diagram, it is observed that the angle formed between the terminal side on the positive y-axis is 90°.
[tex]\rm \frac{pI}{2}[/tex] Is the angle has its terminal side on the positive y-axis.
Hence, option C is correct.

Amanda is walking away from a light pole at a rate of 4 feet per second. If she starts at a distance of 6 feet from the light pole, which of the following fives her distance, d, from the light pole after walking for t seconds.
How far is she at 4 seconds?
i think it would be 960 feet. bc you would multiply 4 by 60, then multiply 240 by 4.
i think thats how you solve it. hope that helped :)
