Answers
Answer:
(11, 2 )
Step-by-step explanation:
3y + 2x = 28 → (1)
x = 5y + 1 → (2)
substitute x = 5y + 1 into (1)
3y + 2(5y + 1) = 28 ← distribute parenthesis on left side and simplify
3y + 10y + 2 = 28
13y + 2 = 28 ( subtract 2 from both sides )
13y = 26 ( divide both sides by 13 )
y = 2
substitute y = 2 into (2)
x = 5(2) + 1 = 10 + 1 = 11
solution is (11, 2 )

FIND SLOPE OF THE LINE ( give me the coordinates too!)
Answers
Answer:
Slope = -1/2.
Step-by-step explanation:
2 points on the line are (10, 0) which is where the line passes through the x-axis and (0, 5 ) where it passes through the y-axis.
The slope = (difference in y coordinates) / ( corresponding difference in x coordinates)
= (5 - 0) / (0 - 10)
= -5/10
= -1/2.
Consider the line y=7/4x-4.
Find the equation of the line that is perpendicular to this line and passes through the point (8,2)
Find the equation of the line that is parallel to this line and passes through the point (8,2)
Answers
Answer:
[tex]\displaystyle \perp\:y = -\frac{4}{7}x + 6\frac{4}{7} \\ \parallel\:y = 1\frac{3}{4}x - 12[/tex]
Step-by-step explanation:
Perpendicular equations have OPPOCITE MULTIPLICATIVE INVERCE RATE OF CHANGES [SLOPES], so 1¾ becomes −⁴⁄₇, and we move forward:
[tex]\displaystyle 2 = -\frac{4}{7}[8] + b \hookrightarrow 2 = -4\frac{4}{7} + b; 6\frac{4}{7} = b \\ \\ \boxed{y = -\frac{4}{7}x + 6\frac{4}{7}}[/tex]
Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so 1¾ remains as is as we proceed:
[tex]\displaystyle 2 = 1\frac{3}{4}[8] + b \hookrightarrow 2 = 14 + b; -12 = b \\ \\ \boxed{y = 1\frac{3}{4}x - 12}[/tex]

Answers
Answer:
i think it would be -14 + 2y so the mistake was making the 2y negative
Step-by-step explanation:
Negative times negative = positive
Answer: The distribution of -2(7 - y) is incorrect. They came out with -14 -2y.
It should have been -14 + 2y
At the end, it would have been a division by +2 , so the solution would be y=3

(9) A software company estimates that if it assigns x programmers to work on the project, it can develop a new product in T days, where T= 100 – 30.x + 3x^2. How many programmers should the company assign in order to complete the development as quickly as possible?
Answers
Using the vertex of the quadratic equation, it is found that the company should assign 5 programmers in order to complete the development as quickly as possible.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex]
[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, the time needed for x programmers to finish the project is given by:
T(x) = 100 - 30x + 3x².
Which means that the coefficients are a = 3, b = -30, c = 100. The number of programmers which will minimize the time is given by:
[tex]x_v = -\frac{-30}{6} = 5[/tex]

What is a linear equation?A linear equation is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let y represent the cost of renting x DVD
They decided to create a membership for $20 flat fee and then charge $4 per DVD for members. For members:
y = 4x + 20
Non-members could also rent a DVD, but for $5 per DVD
y = 5x
The membership would be worth the money if:
5x > 4x + 20
x > 20
The membership would be worth the money if the number of DVD's rented is more than 20

Answer:
Step-by-step explanation:
Part A
Area of a rectangle = length x width
Garden area = 7 3/4 x 2 2/3
= 31/4 x 8/3
= 62/3
= 20 2/3 square feet
Part B
5/8 of the area = 62/3 * 5/8
= 31*5 / 3*12
= 155 / 36
= 4 11/36
The question asks to do so without calculation - the only way is that because the length is approximately 8 feet, section off 5 feet along the length will give an area approximately 5/8 of the total area.
