the solution is going to be all the points that are less than 5 units away from zero
Help please 10 minutes!!!!!!!!!
Substitute y = 2x - 15 to the second equation:
4x + 3(2x - 15) = -5 use distributive property
4x + (3)(2x) + (3)(-15) = -5
4x + 6x - 45 = -5 add 45 to both sides
10x = 40 divide both sides by 10
x = 4
Substitute the value of x to the equation y = 2x - 15:
y = 2(4) - 15 = 8 - 15 = -7

3-6+5 is equal to 2, as opposed to 3-5+6 which is 4. The commutative property is only applicable to positive numbers, in this case, Jerome could have done 5-6+3, which would still equal to 2.
The sign is part of the number.
The first term is +3, the second term is -6, and the third term is +5
In order to use the commutative property so that the -6 and +5 are switched, it would be rewritten as: 3 + 5 - 6
Answer: Jerome did not include the sign with the number when he used the commutative property.

[tex]x=\frac{13}{62}[/tex]
and
[tex]y= \frac{-9}{62}[/tex]e have
EXPLANATION
[tex]17x-3y=4---(1)[/tex]
[tex]2x-4y=1[/tex]
Let us make y the subject and call it equation (2)
[tex]2x=1+4y[/tex]
[tex]x=\frac{1}{2}+2y--(2)[/tex]
We put equation (2) in to equation (1)
[tex]17(\frac{1}{2}+2y)-3y=4[/tex]
[tex]\frac{17}{2}+34y-3y=4[/tex]
[tex]34y-3y=4- \frac{17}{2} [/tex]
Simplify to get,
[tex]31y= \frac{8-17}{2} [/tex]
[tex]31y= \frac{-9}{2} [/tex]
Divide both sides by 31,
[tex]y= \frac{-9}{2} \div 31[/tex]
[tex]y= \frac{-9}{2} \times \frac{1}{31}[/tex]
[tex]y= \frac{-9}{62}[/tex]
We put this value in to equation (2) to get,
[tex]x=\frac{1}{2}+2\times -\frac{9}{62}[/tex]
[tex]x=\frac{1}{2} -\frac{18}{62}[/tex]
We collect LCM to obtain,
[tex]x=\frac{31-18}{62}[/tex]
[tex]x=\frac{13}{62}[/tex]

Given that
Kai is conducting a study about the percentage of students with jobs. His school has 2500 students. He asks everyone in his drama class to participate in a survey. He bases his findings on these results.
Just selecting only students in his drama class to form the sample will not give accurate results since samples are not drawn at random. The sample done is convenient sample saving time, but failing to represent the entire student population with jobs.
THe best sample would be group the students with jobs and select from the group at random a sample size proportional to the population size.

the density of pure gold 1,204 pounds per cubic foot? how many cubic feet is 481.6lbs of pure gold?
Answer:
Volume of Gold = 0.4 cubic feet.
Step-by-step explanation:
First we have to make sure the units are same as the units the answer is required in.
Answer should be given in cubic feet.
Density is given in pounds per cubic foot. And Mass is given in pounds. So units are in order. Therefore, we can go ahead with the calculation.
The Density of Gold = [Mass of Gold/Volume of Gold]
By substituting values,
[tex]1204[/tex] ponds per cubic foot = [[tex]481.6[/tex] pounds / Volume of gold]
Making Volume of God the subject of the equation,
Volume of Gold = [[tex]481.6[/tex] pounds / tex]1204[/tex] ponds per cubic foot ]
Volume of Gold = 0.4 cubic feet.

what is the simplified expression of the following polynomial: xy4 + 5y7 - (6xy + 7y7) - x8y2 + (-3xy4)
This polynomial would simplified as: -2y^7-2xy^4-x^8y^2-6xy (I'm assuming you meant to square the answers)
If you didn't the answer would be: -30xy-14y
But I'm pretty sure you meant to put the first one!
Answer:
[tex](-2y^{7}-2xy^{4}-x^{8} y^{2}-6xy)[/tex]
Step-by-step explanation:
The given expression is [tex]xy^{4}+5y^{7}-(6xy-7y^{7})-x^{8}y^{2}(-3xy^{4})[/tex]
We have to simplify the given expression.
[tex]xy^{4}+5y^{7}-6xy-7y^{7}-x^{8}y^{2}-3xy^{4}[/tex]
[tex](xy^{4} -3xy^{4})+(5y^{7}-7y^{7})-6xy-x^{8}y^{2}[/tex]
[tex]-2xy^{4}-2y^{7}-6xy-x^{8} y^{2}[/tex]
[tex]-2xy^{4}-2y^{7}-6xy-x^{8}y^{2}[/tex]
Therefore, simplified form of the expression will be
[tex](-2y^{7}-2xy^{4}-x^{8} y^{2}-6xy)[/tex]

spent 305.43 on groceries she spent 213.20 in the first month how much did she spend in the second month
Total amount of money spent: 305.42
Money spent the first month: 213.20
Money spent on the second month: ??
Subtract 305.42 - 213.20= Amount of money spent the second month
Answer: 92.23
In Mathematics, the solution to this subtraction problem is to subtract the amount spent in the first month, $213.20, from the total amount spent on groceries, $305.43. The result is $92.23, the amount spent in the second month.
Explanation:This appears to be a simple subtraction problem within the domain of Mathematics. If the total amount spent on groceries is $305.43 and she spent $213.20 in the first month, then to find out how much she spent in the second month, you need to subtract the amount spent in the first month from the total amount.
To solve this, you do the following calculation: $305.43 - $213.20 = $92.23.
Therefore, she spent $92.23 on groceries in the second month.

One number is 3 1/3 larger than the other. The tripled sum of these numbers is 133.What is the largest number?
Let denote the two numbers with X and Y. n represent one number
Y=X + 3 1/3
The sum of the two numbers is: X+Y=X + X + 3 1/3
The triple sum is: 3(X + X + 3 1/3)
3(X + X + 3 1/3) = 133
3X + 3X + 10 = 133
6X + 10 = 133
6X = 123
X = 12 1/2 , Y= X+ 3 1/3 = 12 1/2 = 3 1/3 is the largest number
Answer:
[tex]23\frac{5}{6}[/tex]
Step-by-step explanation:
Let x be the smaller number,
Thus, according to the question,
Second number or larger number = [tex]x+ 3\frac{1}{3}[/tex]
Now, sum of these number = [tex]x+x+ 3\frac{1}{3}=2x+\frac{10}{3}[/tex]
Again according to the question,
[tex]3\times ( 2x + \frac{10}{3})= 133[/tex]
[tex]6x + 10 = 133[/tex]
[tex]6x = 123[/tex]
[tex]\implies x = \frac{123}{6}[/tex]
Thus, the larger number = [tex]\frac{123}{6}+3\frac{1}{3}=\frac{123}{6}+\frac{10}{3}=\frac{123+20}{6}=\frac{143}{6}=23\frac{5}{6}[/tex]
A recent survey of
300 juniors and seniors in physics in a certain high school had the following results: 160 males, 80 junior females, 130 seniors. Draw a vent diagram and label the data.
Answer:
The total number of students in a survey is 300.
Let the number of junior male(JM) be x and the number of senior males(SM) be y.
Let the number of junior female(JF) be p and the number of senior males(SF) be q.
It is given that there are 160 males, 80 junior females, 130 seniors.
Since number of males are 160. So the number of females are,
[tex]300-160=140[/tex]
Since number of junior females is 80.
[tex]JF+SF=140\\80+SF=140\\SF=60[/tex]
Since number of seniors are 130.
[tex]SM+SF=130\\SM+60=130\\SM=70[/tex]
Since number of males is 160.
[tex]JM+SM=160\\JM+70=160\\JM=90[/tex]
Therefore, the table and venn diagram is shown below.
