Step-by-step explanation:
Thursday = x
Friday = 2x (Since thursday is x and she landed up selling twice the amount she did on thursday, friday would be 2x)
Thursday + Friday = 108
For this problem you would need to find the value of x so you would need to substitute x into the equation that was created for the oranges sold on both the days
Thursday + Friday = x+2x = 108
x +2x = 108
3x = 108
x = 108/3
x= 36
Since x is thursday, Marta sold 36 oranges on thursday
To find the amount of oranges sold on friday you would need to multiply x, which is 36, by 2
2x = 2(36) = 72
72 oranges were sold on friday

Oy - 16 = S(x - 2)
Oy - 16 = 3x - 2
3- 16 = S(x - 2)
The relationship is non-linear
Given:
Table of values.
To find:
The equation in point slope form.
Solution:
From the given table it is clear that, the relationship is linear because the rate of change is constant because if x-value increases by 2 then y-values increases by 16.
Consider any two points from the table, i.e., (2,16) and (4,32).
[tex]Slope=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]Slope=\dfrac{32-16}{4-2}[/tex]
[tex]Slope=\dfrac{16}{2}[/tex]
[tex]Slope=8[/tex]
The point is (2,16) and the slope is 8, so the point slope form is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-16=8(x-2)[/tex]
Therefore, the relationship is linear and point slope form is [tex]y-16=8(x-2)[/tex].
Answer:
y - 16 = 8(x - 2)
Ms. Albero decided to make juice to serve along with the pizza at the Student Government party. The directions said to mix 3 scoops of powdered drink mix with 1 gallon of water to make each pitcher of juice. One of Ms. Albero’s students said she will mix 12 scoops with 3 gallons of water to make 4 pitchers. How can you use the concept of proportional relationships to decide whether the student is correct?
Answer:
the student is wrong
Step-by-step explanation:
the og directions said 3 scoops / 1 gallon / 1 pitcher. if you are using 12 scoops, then the gallons of water will be proportional, meaning 3x4=12 scoops / 1x4=4 gallons / 1x4=4 pitchers. if you x4 to one of them, then the directly porportinal values also have to be multiplied by the same number, hence making the student wrong since they should have 4 gallons for 12 scoops

what choice is a solution to the system of equations? y=2x-3 y-9=-x
Answer:
[tex](4,5)\ or\ x=4,y=5[/tex]
Step-by-step explanation:
[tex]We\ are\ given:\\y=2x-3\\y-9=-x\\Now,\ lets\ separate\ all\ the\ constant\ terms\ to\ the\ RHS\ and\ the\ variable\\ terms\ to\ the\ LHS.\\Hence,\\y-2x=-3\\y+x=9\\By\ subtracting\ the\ two\ equations:\\(y-2x)-(y+x)=(-3)-(9)\\Hence\ lets\ simplify\ this\ main\ equation: \\y-2x-(y+x)=-3-9\\y-2x-y-x=-12\\-3x=-12\\x=\frac{-12}{-3}=4\\\\Now,\ lets\ consider\ the\ second\ equation\ in\ the\ solution:\\y-9=-x\\Substituting\ x=4,\\y-9=-(4)\\y-9=-4\\y=-4+9\\y=5\\[/tex]
[tex]Now,\\We\ get\ the\ solution\ to\ this\ system\ of\ equations:\\x=4,y=5\\By\ putting\ this\ as\ a\ co-ordinate\ pair (x,y):\\(4,5)[/tex]
Answer:
The solution of the system of equations will be:
[tex]y=5,\:x=4[/tex]
Step-by-step explanation:
Given the system of equation
[tex]\begin{bmatrix}y=2x-3\\ y-9=-x\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}y-2x=-3\\ y+x=9\end{bmatrix}[/tex]
so
[tex]y+x=9[/tex]
[tex]-[/tex]
[tex]\underline{y-2x=-3}[/tex]
[tex]3x=12[/tex]
so the system of equations becomes
[tex]\begin{bmatrix}y-2x=-3\\ 3x=12\end{bmatrix}[/tex]
solve 3x=12 for x
[tex]3x=12[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}=\frac{12}{3}[/tex]
[tex]x=4[/tex]
[tex]\mathrm{For\:}y-2x=-3\mathrm{\:plug\:in\:}x=4[/tex]
[tex]y-2\cdot \:4=-3[/tex]
[tex]y-8=-3[/tex]
Add 8 to both sides
[tex]y-8+8=-3+8[/tex]
[tex]y=5[/tex]
Thus, the solution of the system of equations will be:
[tex]y=5,\:x=4[/tex]

Answer:
-108
Step-by-step explanation:
About the easiest way to do this for small values of n is to compute each of the terms using the given recurrence relation.
[tex]a_1=4\\\\a_2=-3a_1=-3(4)=-12\\\\a_3=-3a_2=-3(-12)=36\\\\a_4=-3a_3=-3(36)=-108\\\\\boxed{a_4=-108}[/tex]
_____
Alternate solution
You recognize that the recurrence relation describes a geometric sequence with a first term of 4 and a common ratio of -3. The n-th term of a geometric sequence is ...
[tex]a_n=a_1\cdot r^{n-1} \qquad\text{for first term $a_1$ and common ratio $r$}[/tex]
Then the 4th term will be ...
[tex]a_4=4\cdot(-3)^{4-1}=4\cdot(-27)=-108[/tex]

Kaitlyn's older brother borrowed money for school he took out a loan that charges 6% simple interest he will end up paying 720 and interest after 6 years how much is Kaitlyn's brother borrow for school?
please please help asap
Answer: 2000
Step-by-step explanation:
The following can be gotten from the question:
Principal = Unknown
Rate = 6%
Time = 6 years.
Interest = 720
Note that: Interest = PRT / 100
720 = (P × 6 × 6) / 100
720 = 36P / 100
720 × 100 = 36P
72000 = 36P
Principal = 72000 / 36
Principal = 2000
The amount that he borrowed is 2000.

Mr Brown has 2 children are going to london by train 1 adult costs £24 and child ticket costs 12 1/3 off adults tickets and 60% off child ticket
Complete Question
Mr Brown has 2 children are going to london by train
1 adult costs £24 and child ticket costs 12
The Family Railcard offers:
1/3 off adults tickets and 60% off child ticket
What is the total cost of tickets when Mr Brown uses the Family Railcard
Answer:
£25.60
Step-by-step explanation:
From the question:
1 adult costs £24
The Family Railcard offers:
1/3 off adults tickets.
Hence:
1/3 × £24 = £8
The cost for Mr Brown = £24 - £8
= £16
Child ticket costs £12
The Family Railcard offers:
60% off child ticket
Hence = 60% × £12
= 60/100 × £12
= £7.2
The cost for 1 child = £12 - £7.2
= £4.8
The total cost of tickets when Mr Brown uses the Family Railcard is:
Cost for Mr Brown + Cost for his 2 Children
£16 + 2 × £4.8
£16 + £9.6
= £25.60

Each person in a group of twenty people at a hotel orders one meal chosen from oatmeal, eggs, or pancakes and one hot beverage chosen from coffee or tea. One person will be selected at random from the twenty people. What is the sample space for the meal and beverage for the person selected
Answer:
[tex]S = \{(Oatmeal, Coffee),(Eggs, Coffee),(Pancakes,Coffee),[/tex] [tex](Oatmeal, Tea),(Eggs, Tea),(Pancakes,Tea)\}[/tex]
Step-by-step explanation:
Given
[tex]Meal = \{Oatmeal, Eggs, Pancakes\}[/tex]
[tex]Beverage = \{Coffee, Tea\}[/tex]
Required
Determine the sample space
The sample space is a list of combination of 1 meal and 1 beverage.
Because one individual can order only one of the meals and one of the beverages at any one time, then no two orders can be the same
The sample space (S) is as follows:
[tex]S = \{(Oatmeal, Coffee),(Eggs, Coffee),(Pancakes,Coffee),[/tex] [tex](Oatmeal, Tea),(Eggs, Tea),(Pancakes,Tea)\}[/tex]
Which phrase best describes the graph of a proportional relationship?
OA. a straight line passing through the origin
OB.
a straight line
Ос.
a curve
OD
not a straight line
Answer:
A straight line passing through the origin
Step-by-step explanation:
A proportional relationship will have a particular quantity being related to another
For example, the relationship might be inverse or direct
In this case, we can have a straight line graph that passes through the origin
A straight line graph that passes through the origin would show the proportional relationship as it has no slope whatsoever

Step 1: Define
-12(x + 4) + 14x = 60
Step 2: Solve for x
Distribute -12: -12x - 48 + 14x = 60Combine like terms: 2x - 48 = 60Add 48 to both sides: 2x = 108Divide 2 on both sides: x = 54Answer:
x = 54
Step-by-step explanation:
-12(x + 4) + 14x = 60
i) distribute -12 to the whole parentheses of (x+4)
(-12 × x) + (-12 × 4) + 14x = 60
-12x - 48 + 14x = 60
ii) collect like terms
-12x + 14x - 48 = 60
2x - 48 = 60
iii) move constant to the right-hand side and change its sign
2x = 60 + 48
iv) add the numbers
2x = 108
v) divide both sides of the equation by 2
[tex] \frac{2x}{2} = \frac{108}{2} [/tex]
x = 54
