Solve the system (2 points)
Write the solution as a point (x, y) (2 points)
Answers
Answer:
x = -5 y = -5
Step-by-step explanation:
–x + 4y = -15
- 4y -4y
-1(-x = -4y - 15)
x = 4y + 15
Substitute x = 4y + 15 into 3x + 5y = -40
3(4y + 15) = -40
17y + 45 = -40
- 45 -45
17y = -85
/ 17 /17
y= -5
Substitute y = - 5 into x = 4y + 15:
x = 4(-5) + 15
x = -20 + 15
x = -5
Answer:
Part I
(-5,-5)
Part II
(3.75, 312.50)
Step-by-step explanation:
Part I
(1) 3x + 5y = -40
(2) -x + 4y = -15
solve for x in (2)
x = 15 + 4y
substitute into (1)
3(15+4y) + 5y = -40
45 +12y + 5y = -40
45 +17y = -40
17y = -85
y = -5
substitute y = -5 into (1)
3x + 5(-5) = -40
3x -25 = -40
3x = -15
x = -5
so (-5, -5)
Part II
Studio A
C = 125 + 50t
Studio B
C = 200 + 30t
125 + 50t = 200 + 30t
20t = 75
t = 3.75
(3.75, 312.50)

Given 300mL of a gas at 17.0 degrees Celsius, what is the volume at 10 degrees Celsius if the pressure remains constant?
Answers
Answer:
292.75mL
Step-by-step explanation:
From the ideal gas equation
PV= nRT
With each symbols having standard meaning
For pressure remaining constant the equation for two states can be written as
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]
Given V_1 = 300mL, T_1 = 17° C = 290K and T_2 = 10°C or 283K
Now plugging values in above equation to find V_2
[tex]\frac{300}{290} =\frac{V_2}{283}\\V_2 =\frac{300}{290}\times283 = 292.75mL[/tex]
Therefore, the volume at 10 degrees Celsius = 292.75mL

You need a mean of at least 90 points to advance to the next round of the touch-screen trivia. What score in the fifth game will allow you to advance
Answers
Answer:
At least 98 is needed in the 5th game
Step-by-step explanation:
The missing parameters are:
[tex]Game\ 1 = 95[/tex]
[tex]Game\ 2 = 91[/tex]
[tex]Game\ 3 = 77[/tex]
[tex]Game\ 4 =89[/tex]
[tex]Mean = 90[/tex] at least
Required
The score in game 5 to make you advance
Mean is calculated as:
[tex]Mean = \frac{\sum x}{n}[/tex]
So, we have:
[tex]Mean = \frac{95 + 91 + 77 + 89 + Game\ 5}{5}[/tex]
[tex]Mean = \frac{352 + Game\ 5}{5}[/tex]
The mean must be at least 90.
So, we have:
[tex]\frac{352 + Game\ 5}{5} \ge 90[/tex]
Multiply both sides by 5
[tex]5 * \frac{352 + Game\ 5}{5} \ge 90 * 5[/tex]
[tex]352 + Game\ 5 \ge 450[/tex]
Make Game 5 the subject
[tex]Game\ 5 \ge450 - 352[/tex]
[tex]Game\ 5 \ge 98[/tex]
At least 98 is needed in the 5th game

How to find Gradient and y intercept
Answers
Find two points on the line and with those two points, calculate the difference in height(y coordinates) divided by the difference in width(x coordinates). If you get a positive value, then your line will be uphill.
Y-intercept:
Use y=mx+b
Find the slope first using the slope formula which is y2-y1 OVER x2-x1. Once you have that, take a point from the line and substitute the x and y coordinates along with the slope into y=mx+b.
So if your slope was 2/1 and your point was (4,8), it would be:
8=2(4)+b
8=6+b
*subtract 6 from both sides*
b=2

B. The account balance will increase 0.04% each year.
C. The account balance will decrease 4% each year.
D. The account balance will increase 4% each year.
Answers
Answer:
D. The account balance will increase 4% each year.
Step-by-step explanation:
Given the equation :
A= 1750(1.04)t
This is an exponential growth rate equation which has it's general format as :
A = A0 * (1 + r)^t
A0 = initial value,
Since (1 + r) is greater Than 1 ; then we conclude that it is a growth relation.
1 + r = 1.04
The rate, r = (1.04 - 1) = 0.04
r = 0.04 = (0.04 * 100%) = 4%
Hence, The account balance will increase 4% each year.

A brick wall will be shaped like a rectangular prism. The wall needs to be 3ft tall and the builders have enough bricks for the wall to have a volume of 330 cubic feet. What tool can be used to find possible dimensions for the base of the wall?
Answers
Answer:
For a rectangular prism that has a base area B, and a height H, the volume is:
V = B*H
This is the only "tool" that we need to use in this situation.
We know that the wall needs to be 3ft tall, then H = 3ft
And we also know that we have enough bricks for a wall of a volume:
V = 330 ft^3
If we replace these two in the volume equation, we get:
330ft^3 = B*3ft
Now we can solve this for B, and thus find the volume of the base of the wall.
To do it, we just need to divide both sides by 3ft
(330 ft^3)/3ft = B*3ft/3ft
110 ft^2 = B
This means that the area of the base is 110ft^2
As the base is a rectangle of width W and length L, we must have:
110ft^2 = B = L*W
Then the possible measures of the base are given by the linear relation:
L = 110ft^2/W
Where we also need to add some trivial restrictions, like:
L > 0 ft
W > 0ft
This only means that we can not have a length or width equal to or smaller than zero, as those do not have physical sense.

Emma bought two televisions at 2500.00 each.One got slightly damaged during transportation.He sold the undamaged one at 3000.00 and sold the damaged one at 2200.00.Calculate the profit made by Emma
Answers
Answer:
200.00
Step-by-step explanation:
Cost of 2 television at 2,500.00 each = 2 × 2,500.00
= 5000.00
Cost of 2 television = 5,000.00
Selling price of the undamaged TV = 3000.00
Selling price of the damaged TV = 2200.00
Total selling price = 3000.00 + 2200.00
= 5,200.00
Total selling price = 5,200.00
Profits = selling price - cost price
= 5,200.00 - 5,000.00
= 200.00
Profits = 200.00
