Answer:
[tex]y = 75 + 10x[/tex]
Step-by-step explanation:
Given
New Video Games
[tex]Cost = \$25[/tex]
[tex]Number = 3[/tex]
Used Video Games
[tex]Cost = \$10[/tex]
[tex]Number = x[/tex]
Required
Determine the amount spent (y)
First, we need to determine the total spent on new games
1 new game = $25
3 new games will be: 3 * $25
Next, we determine the total spent on old games
1 used game = $10
x used games will be: x * $10
So, total amount y, is:
[tex]y = 3 * 25 + x * 10[/tex]
[tex]y = 75 + 10x[/tex]
Is this equation linear?
yes it is a linear factor, my sister told me the answser

Kayla is on level 12 of a new game. Everyday she completes 6 new levels. Maddy is on level 28 of the same game. Everyday she completes 2 new levels.
Write your system to represent where Kayla and Maddy are in the video game
Answer:
Kayla and Maddy will be in the same level in 4 days.
Step-by-step explanation:
Kayla: y = 6x + 12
Maddy: y = 2x + 28
6x + 12 = 2x + 28
Subtract 2x from both sides;
4x + 12 = 28
Subtract 12 from both sides;
4x = 16
Divide both sides by 4;
x = 4
Answer:
Step-by-step explanation:
y = 6x + 12
y = 2x + 28
or
l = 6d + 12
l = 2d + 28

Answer:
x = 62
Step-by-step explanation:
All angles of a triangle add up to 180°.
[tex]180-(68.5+49.5)\\\\180-(118)\\\\180-118\\\\\boxed{62}[/tex]
The third angle should be 62°. Therefore, x = 62.

the square root of 90 is it closer to 9 or 10
Answer:
9
Step-by-step explanation:
9² = 81
10² = 100
81 ... 90 ... 100
90 - 81 = 9
100 - 90 = 10
9 is less than 10
Hence, √90 is closer to 9

what is the solution to the system of equations?
Answer:
No solution
Step-by-step explanation:
[tex]-3x-4y-3z=-7\\2x-6y+2z=3\\5x-2y+5z=9\\\\[/tex]
Lets consider the equation 2.
Here we multiply the LHS and RHS with (-1).
[tex]-3x-4y-3z=-7\\-(2x-6y+2z)=-3\\5x-2y+5z=9\\\\[/tex]
Hence,
[tex]-3x-4y-3z=-7\\-2x+6y-2z=-3\\5x-2y+5z=9\\\\[/tex]
When we add the equations we get,
[tex]0x+0y+0z=-10+9\\Hence,\\0=-1[/tex]

Explain how solving -7y > 161 is different from solving 7y > -161.
Answer:
Sample response: Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>

whats the equation for the in slope intercept form?
Answer: y = -4x + 5
Step-by-step explanation:
To write the equation in slope intercept form, we need to find the slope and the y intercept.
The y intercept is when the x coordinate is zero, and looking at the line we can say the y-intercept is 5 because when x is 0 y is 5
y intercept: (0,5)
Now find another point on the line to find the slope of the line .
(-2,13)
The slope is the difference between the y coordinates divided by the difference in the x coordinates.
(0,5) and (-2,13)
y coordinates: 5 - 13 = -8
x coordinates: 0 - (-2) = 2
Slope: -8/2 = -4

A baseball team had $250 to spend on supplies. The team spent $46.25 on a new bat. New baseballs cost $2 each. The inequality46.25+2b≤250 can be used to determine the number of new baseballs, b, that the team can purchase.
Answer: 101
[tex]\leq 46,25+2b\leq 250\\\\=> 2b\leq 250-46,25=203,75\\\\<=> b\leq 203,75/2=101,876[/tex]
but b is the number of new baseballs
=> [tex]b\leq 101[/tex]
=> the team can purchase 101 baseballs
Step-by-step explanation:
Rollin and Sandra want to buy a home priced at $265,000. They plan to finance this amount less the down payment
required. Rollin and Sandra have a combined annual income of $83,600 and have saved $53,000. They have a
recurring debt of $582. Use a 20% down payment and the 28/36 ratio to determine if Rollin and Sandra are eligible for
a loan. What would you advise them to do if they are not eligible?
Answer:
Rollin and Sandra will not be eligible for a loan. Since 20% of $265,000 is $53,000, they have the required down payment.The recurring debt they have exceeds the allowable amount of $557. Rollin and Sandra should work on reducing their recurring debt.
Step-by-step explanation: this is what i put on the practice
Based on the 28/36 rule, the Rollin and Sandra family are eligible for the mortgage loan of $212,000.
Data and Calculations:Price of home = $265,000
Required down payment = 20% or $53,000
Amount saved = $53,000
Combined annual income of Rollin and Sandra = $83,600
Recurring debt = $582 per month
Annual recurring debt = $6,984 ($582 x 12)
The Rollin and Sandra family will need to finance $212,000 ($265,000 - $53,000) of the home price.
At 6% interest rate for 30 years, the Rollin and Sandra household will pay $1,271.05 monthly or $15,252.60 yearly. This gives a total annual debt payment of $22,236.60 ($6,984 + $15,252.60).
Thus, based on the 28/36 rule, the Rollin and Sandra family are eligible for the mortgage loan of $212,000.

What have you heard about "building your credit score"
Answer: ”Building your credit score” is what many people try to do and is an important part of your financial health. You want good credit scores because they can unlock many savings and benefits, including access to loans and credit cards with the most favorable terms.
Step-by-step explanation: Establishing a good credit score is one of the most important things you'll ever do. Good credit is essential throughout your life, whether you want to buy a house or car, get insurance or maybe even pay less of a deposit for utilities. It will take about six months of credit activity to establish enough history for a FICO credit score, which is used in 90% of lending decisions. FICO credit scores range from 300-850, and a score of over 700 is considered a good credit score. Scores over 800 are considered excellent. Therefore, 850 would be the best credit score.

In what form is an equation that relates two proportional quantities x and y?
A.
y=k+x, where k is the constant of proportionality
B.
y=kx, where k is the constant of proportionality
C.
y=kx, where k is the constant of proportionality
D.
y=xk, where y is the constant of proportionality
Answer:
Step-by-step explanation: The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

A rectangle has a length of (x+10) centimeters and a width of x centimeters. If the perimeter is 32 centimeters, what is the length of the rectangle?
Given:
Length of rectangle = (x+10) cm
Width of the rectangle = x cm
Perimeter = 32 cm
To find:
The length of the rectangle.
Solution:
We know that,
[tex]Perimeter=2(l+w)[/tex]
Where, l is length and w is width.
Substituting the values, we get
[tex]32=2((x+10)+x)[/tex]
[tex]32=2(2x+10)[/tex]
[tex]32=4x+20[/tex]
Subtract 20 from both sides.
[tex]32-20=4x[/tex]
[tex]12=4x[/tex]
Divide both sides by
[tex]3=x[/tex]
So, the length is
[tex]3+10=13[/tex]
Therefore, the length of the rectangle is 13 cm.
Please answer 4 question y
Answer:
The median of these numbers is 42.
Step-by-step explanation:
First we have to list these numbers from least to greatest so we can get an accurate answer.
5, 21, 36, 42, 56, 75
We know that the median is the number in the exact middle of a group of numbers from least to greatest, but in this case there are 6 numbers so what do we do? All you have to do is find the average of the two numbers in the middle. So, 42 + 36 divided by 2 = 78/2 = 39.
