solve the system of equations
Answer:
(x, y) = ( 5, 6)
(x, y) = ( - 1, 0)
Step-by-step explanation:
[tex] \begin{cases} y + x^2 - 5x = 6\\\\ y - x = 1\implies y = x + 1\end{cases} [/tex]
Plug [tex] y = x +1 [/tex] in the equation [tex] y + x^2 - 5x = 6[/tex] we find:
[tex] x + 1 + x^2 - 5x = 6[/tex]
[tex] x^2 - 4x - 5=0[/tex]
[tex] x^2 - 5x +x- 5=0[/tex]
[tex] x(x - 5) +1(x- 5)=0[/tex]
[tex] (x - 5) (x+1)=0[/tex]
[tex] (x - 5) =0, \: (x+1)=0[/tex]
[tex] x =5, \: x=-1[/tex]
[tex] When \:x =5 \implies y =5+1=6 [/tex]
(x, y) = ( 5, 6)
[tex] When \:x =-1 \implies y =-1+1=0 [/tex]
(x, y) = ( - 1, 0)

A bag contains 8 red M&Ms, 13 blue M&Ms, 4 brown M&Ms, and 8 green M&Ms. An M&M is picked at random from the bag. What is the probability of picking: A Red M&M:
Given:
Number of red M&Ms = 8
Number of blue M&Ms = 13
Number of brown M&Ms = 4
Number of green M&Ms = 8
An M&M is picked at random from the bag.
To find:
The probability of picking a red M&M.
Solution:
We have,
Number of red M&Ms = 8
Total number of M&Ms [tex]= 8+13+4+8[/tex]
[tex]=33[/tex]
So, probability of picking a red M&M is:
[tex]\text{Probability}=\dfrac{\text{Number of red M&Ms}}{\text{Total number of M&Ms}}[/tex]
[tex]\text{Probability}=\dfrac{8}{33}[/tex]
Therefore, the probability of picking a red M&M is [tex]\dfrac{8}{33}[/tex].

B. $13.75 per month
C. $15.00 per month
D. $7.14
The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
Johnny's rate of saving over the 12 months is $14 per month.
Option A is the correct answer.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
From the graph, we have the following coordinates.
= (5, 70)
This means after 5 months $70 is saved.
= (10, 140)
This means after 10 months $140 is saved.
Johnny's rate of savings.
= Change in the savings amount/change in the months
= (140 - 70) / (10 - 5)
= 70/5
= $14
Thus,
Johnny's rate of saving over the 12 months is $14 per month.
Option A is the correct answer.

Find the volume of this cone.
Round to the nearest tenth.
10ft
6ft
Answer:
433.5
Step-by-step explanation:
The volume of the cone with a radius of 6ft and a height of 10ft is approximately 301.4 cubic feet.
What is the volume of the cone?A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.
The volume of a cone is expressed as;
V = (1/3)πr²h
Where r is the radius of the base, h is the height of the cone and π is constant pi ( π = 3.14 ).
From the diagram:
Slant height l = 10 ft
Radius r = 6 ft
Height h =?
Volume V =?
First, we determine the height of the cone using Pythagoras theorem:
h² = 10² - 6²
h² = 100 - 36
h² = 64
h = √64
h = 8
Plug the values into the above formula and solve for the volume:
V = (1/3)πr²h
V = (1/3) × 3.14 × 6² × 8
V = (1/3) × 3.14 × 36 × 8
V = 301.4 ft³
Therefore, the volume is approximately 301.4 cubic feet.

The following table represents the total cost, in dollars (y) to join a gym for x number of months. The cost includes a one-time joining fee of 10$. Does the data in the table represent a proportional relationship? How do you know?
Answer:
The table does not represent a proportional relationship because the ratio of the y-values to the corresponding x-value at each data point is not constant
y/x ≠ Constant
Step-by-step explanation:
The table of values for the total cost in dollars (y) to join a gym for "x" number of months is presented as follows;
x; 1, 2, 3, 4, 5
y; 25, 40, 55, 70, 85
The rate of change of the data in the table is given by the following formula;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Between the 1st and the 3rd point, we have;
m = (55 - 25)/(3 - 1) = 15
Between the 1st and the 5th point, we have;
m = (85 - 25)/(5 - 1) = 15
Therefore, the rate of change of the y values per unit change of the x-value is 15
Therefore, the "x" and y-values have a linear relationship
However, for a proportional relationship, we have;
y/x = Constant
At the 1st point, we have;
25/1 = 25
At the 3rd point, we have;
55/3 = 18.[tex]\overline 3[/tex]
∴ y/x is not constant and the the data in the table does not represent a proportional relationship.

The required volume of the figure is 50π cubic meters.
What is the volume of a cone?The volume of a cone is defined as the amount of space occupied by a cone in a three-dimensional plane.
The volume of an oblique circular cone is given by the formula:
V = (1/3) × π × r² × h
Where V is the volume, π is approximately 3.14, r is the radius, and h is the height.
As per the question, we are given that the radius is 5 meters and the height is 6 meters, so we can substitute these values into the formula:
V = (1/3) × π × (5²) × 6
V = (1/3) × π × 25 × 6
V = (1/3) × π × 150
V = 50π
Therefore, the volume of the figure is 50π cubic meters.

QuadrilateralsThere are different types of quadrilaterals, for example: square, rectangle, rhombus, trapezoid and parallelogram. Each type is defined accordingly to its length of sides and angles. For example, the opposite sides for a parallelogram are equal and parallel.
Considering that the opposite sides of the parallelogram (ABCD) are equal and parallel, so AD=DC. Therefore,

A dance studio requires each dancer to pay a registration fee plus an hourly rate for all lessons. If the total cost, y, of a dancer's lesson is modeled by the equation y = 25x + 50, how could the y-intercept be interpreted?
Answer:
(0,50)
Step-by-step explanation:
Given the total cost of a dancers lesson modeled by the equation y = 25x + 50, the y intercept occurs at the point where x = 0.
Substitute x = 0 into the expression
y = 25x + 50
y = 25(0) + 50
y = 0+50
y = 50
Hence the y intercept is (0, 50). This shows that the total cost of the dancers lesson registration fee is 50
