Solve this system of equations by using the elimination method -3x+y=6 -3x+y=12
Answer:
None
Step-by-step explanation:
We can eliminate the x's by add the 2 equations :
2y = 18
Divide both sides by 2 :
y = 9
Substitute this value into equation 1 to solve for x :
-3x + (9) = 6
Subtract 9 from both sides :
-3x = -3
Divide both sides by -3 :
x = 1
Substitute these values into equation 2 to check :

Twelve of the 20 students in Mr. Skinner’s class brought lunch from home. Fourteen of the 21 students in Ms. Cho’s class brought lunch from home. Siloni is using two 15-section spinners to simulate randomly selecting students from each class and predicting whether they brought lunch from home or will buy lunch in the cafeteria.
If each spinner is divided into 15 congruent sectors, how does the spinner representing Mr. Skinner’s class differ from the spinner representing Ms. Cho’s class?
For Ms. Cho's class, the formula is =randBetween(1,21). The result of interest is 14 or less.
12/20 reduces to 4/5 --> 4/5 of 15 is 12.
So using the spinner to model Mr. Skinner's class, an outcome of the select 12 sections of interest represent, symbolize, and model a student bringing lunch from home.
LIkewise, 14/21 reduces to 2/3 --> 2/3 of 15 is 10.
So using the spinner to model Ms. CHo's class, an outcome of only 10 of the 15 sections of interest represent, model, and symbolize a student who brings lunch from home.
The same can be done in Excel: The function is =randBEtween( minVal, maxVal)
For example =randBetween(1,20) will model Mr. Skinner's class. A result of 12 or less represents, model, simulates, and symbolizes a student who packed their lunch.
For Ms. Cho's class, the formula is =randBetween(1,21). The result of interest is 14 or less.

Triangle RST is rotated 180° about the origin, and then translated up 3 units. Which congruency statement describes the figures?
ΔRST ≅ ΔACB
ΔRST ≅ ΔABC
ΔRST ≅ ΔBCA
ΔRST ≅ ΔBAC
The congruency statement that describes the figure is: D. ΔRST ≅ ΔBAC.
What is a Congruency Statement?A congruency statement is a statement that states that two triangles are congruent to each other.
180 degrees rotation around the origin will give us the rule: (x, y) → (-x, -y)
Therefore, applying this rule to triangle RST that was rotated, we would have:
R'(-1, -1)
S'(-3, -4)
T'(-5, 0)
Translating R'S'T' 3 units up, using the rule, (x, y + 3) will give us:
B(-1, 2)
A(-3, -1)
C(-5, 3)
Therefore, we can conclude that, D. ΔRST ≅ ΔBAC.

Which statement is true about the end behavior of the graphed function?
As the x-values go to positive infinity, the function's values go to negative infinity.
As the x-values go to zero, the function's values go to positive infinity.
As the x-values go to negative infinity, the function's values are equal to zero.
As the x-values go to positive infinity, the function's values go to positive infinity.
The correct option is:
As the x-values go to positive infinity, the function's values go to positive infinity.
What is the end behavior of the function?
By the description, We know that the function has the points:
(-1.25, -3.25), (0.25, -1.75) (-2.25, 0), (0, -2), (-2.75, 6), (1.5, 6)
Notice that from x = 0.25 to x = 1.5 the function goes upwards, then in the right side, the function goes up, so as x goes to positive infinity, also does f(x).
On the left side, we can see that from x = -2.75 to x = -2.25 the function goes downwards.
So, as x goes to the left (negative infinity) f(x) goes upwards.
Then as x tends to negative infinity, f(x) tends to infinity.

Juan, Carlos and Manu take turns flipping a coin in their respective order. The first one to flip heads wins. What is the probability that Manu will win
Answer:
⅓ ×½ which will give you ⅙
Step-by-step explanation:
because
The probability that Manu will win the coin flip amongst others is 4/7
What is the probability that Manu will win?To determine the probability that Manu will win, we need to consider the possible outcomes of the coin flips.
Let's break down the scenarios:
Scenario 1: Manu wins on the first flip
- The probability of Manu winning on the first flip is 1/2, as he needs to flip heads right away.
Scenario 2: Manu wins on the second flip
- Juan flips tails (1/2 probability)
- Carlos flips tails (1/2 probability)
- Manu flips heads (1/2 probability)
- The probability of Manu winning on the second flip is (1/2) * (1/2) * (1/2) = 1/8.
Scenario 3: Manu wins on the third flip
- Juan flips tails (1/2 probability)
- Carlos flips tails (1/2 probability)
- Manu flips tails (1/2 probability)
- Juan flips heads (1/2 probability)
- Carlos flips heads (1/2 probability)
- Manu flips heads (1/2 probability)
- The probability of Manu winning on the third flip is (1/2) * (1/2) * (1/2) * (1/2) * (1/2) * (1/2) = 1/64.
The pattern continues, and we can see that Manu's probability of winning decreases exponentially with each subsequent flip.
Therefore, the total probability of Manu winning is the sum of the probabilities from each scenario:
1/2 + 1/8 + 1/64 + ...
This is an infinite geometric series with a first term (a) of 1/2 and a common ratio (r) of 1/8.
Using the formula for the sum of an infinite geometric series:
Sum = a / (1 - r)
Sum = (1/2) / (1 - 1/8)
Sum = (1/2) / (7/8)
Sum = (1/2) * (8/7)
Sum = 4/7
Therefore, the probability that Manu will win is 4/7.

brushes and 8 tubes of paint that will cost $43.
What is the cost of one brush? What is the cost of
one tube of paint?
Answer:
A brush: $4.50
A tube of paint: $2
Step-by-step explanation:
Let b = brushes
Let p = paint
1) Set up equations.
4b + 7p = 32
6b + 8p = 43
2) Solve the system of equations using elimination.
(4b + 7p = 32)3
(6b + 8p = 43)2
-----------------------
12b + 21p = 96
12b + 16p = 86
----------------------
5p = 10
p = 10/5
p = 2
Substitute 2 into p of any of the two equations.
4b + 7(2) = 32
4b + 14 = 32
4b = 32 - 14
4b = 18
b = 18/4
b = 4.50
Therefore, a brush costs $4.50, while a tube of paint costs $2.

The probability that, at the tip of the fourth round, each of the players has four coins is 5/192.

Case 2: [tex]\%R_{A}[/tex]=2 and [tex]\%R_B[/tex]=4. There are 3 ways to position the -1 in [tex]R_A[/tex], 2 ways to put the remaining -1 in [tex]R_B[/tex] (just don't put it under the -1 on top of it!), and a pair of ways for one among the opposite two players to draw the green ball.

Case 3: [tex]\%R_A=\%R_B=2[/tex]. There are 3 ways to put the -1 in [tex]R_{A}[/tex]. Now, there are two cases on what happens next.
The 1 in [tex]R_B[/tex] goes directly under the -1 in[tex]R_A[/tex]. There's obviously 1 way for that to happen.

(Either the 1 comes first in[tex]R_C[/tex] or the 1 comes first in [tex]R_D[/tex].)The 1 in [tex]R_B[/tex] doesn't go directly under the -1 in [tex]R_A[/tex]. There are 2 ways to put the 1, and a couple of ways to try and do the identical permutation as within the above case.Hence, there are 3(2+2×2)=18 ways for this case. There's a grand total of 45 ways for this to happen, together with 12³ total cases. The probability we're soliciting for is thus 45/(12³)=5/192

A cylindrical can, open at the top, is to hold 230 cm3 of liquid. find the height and radius that minimize the amount of material needed to manufacture the can. enter answer with rational exponents.
The height and the radius that minimize the material needed to manufacture the can is 4.18336 cm and 4.18337 cm respectively.
Computed using differentiation.
We assume the radius of the can be r cm, and its height to be h cm.
We are given that the can is to hold 230 cm³ of liquid, thus the volume of the can is:
V = 230,
or, πr²h = 230 {Since, the volume of a cylinder is πr²h, where r is the radius, and h is the height},
or, h = 230/(πr²) ... (i) .
We are asked to find the height and radius that minimize the amount of the material.
To calculate the amount of the material, we calculate the surface area of the can (A).
The surface area of the can = area of the base + area of the side,
or, A = πr² + 2πrh = πr(r + 2h).
Substituting h = 230/(πr²), we get:
A = πr(r + 2{230/(πr²)}),
or, A = {πr(πr³ + 460)}/πr² = πr² + 460/r.
Differentiating both sides with respect to the radius r, we get:
dA/dr = 2πr - 460/r² ...(ii)
To find the point of inflection, we equate this to zero, to get:
2πr - 460/r² = 0,
or, 2πr = 460/r²,
or, r³ = 460/2π = 73.2113,
or, r = 4.18337 cm.
To check whether the point of inflection shows the point of maximum or minimum, we differentiate (ii) with respect to the radius r, to get:
d²A/dr² = 2π + 920/r³, which is always positive when the radius r is positive.
Thus, the area is minimum when the radius r = 4.18337 cm.
Height, h = 230/(πr²) = 4.18336 cm.
Thus, the height and the radius that minimize the material needed to manufacture the can is 4.18336 cm and 4.18337 cm respectively.

Make tables to find the solution to 8x = 2x + 2. Take the integer values of x between -3 and 3.
Answer:
i'm not realy sure what you mean by a table
8x=2x+2
subtract 2x from each side
6x=2
divide by 6
x=1/3
Hope This Helps!!!
Step-by-step explanation:
So if you want to make a table to find the solution, you'll need 3 columns, one will be the value of x, the other two will be the value of the equation (left and right) and then you'll need to look where the two equations are equal, and the solution is whatever the x-value is. It'll look something like this:
[tex]x\ \ \ \ |\ 2x+2\ |8x\\-3\ \| -4\ \ \ \ \ | -24\\-2\ \| -2\ \ \ \ \ |-16\\-1\ \| 0\ \ \ \ \ \ \ \ \ | -8\\0\ \ \ \ \|2\ \ \ \ \ \ \ \ \ | 0 \\1\ \ \ \ \| 4\ \ \ \ \ \ \ \ \ | 8\\2\ \ \ \ \|6\ \ \ \ \ \ \ \ \ | 16\\3\ \ \ \ \|8\ \ \ \ \ \ \ \ \ | 24[/tex]
As you can see, none of rows (the two right most columns with the equations) are ever equal, on the same row. This is because the solution is not an integer. If you solve it algebraically. You'll get this:
Original equation
8x = 2x+2
Subtract 2x from both sieds
6x = 2
Divide both sides by 6
x = 2/6
Simplify the fraction
x=1/6
