X/5 + 3 = 2 pls help
Answer:
x=-5
Step-by-step explanation:
Group all constants on the right side of the equation
Subtract 3 from both sides:
x/5+3-3=2-3
Simplify the arithmetic:
x/5=2-3
Simplify the arithmetic:
x/5=-1
Isolate the x
Multiply to both sides by 5:
x/5 ·5= -1 · 5
Group like terms:
1/5 · 5x = -1 · 5
Simplify the fraction:
x = -1 · 5
Simplify the arithmetic:
x = -5

_x+5=4(–x–5) help pls
Answer:
Assuming the equation is: _x+5=4(–x–5) and not -x+5=4(–x–5),
Step-by-step explanation:
_x+5=4(–x–5)
_x+5=–4x–20
_x =–4x–25
_x +4x=–25
(4+_x) = -25
There is nothing left to do without more information.

Otherwise:
-x+5=4(-x-5)
-x+5=-4x-20
-3x = -25
x = -(25/3)

You are selling tickets. You make $50 for signing up to sell tickets. You also make $0.75 for each ticket you sell. Write an equation in slope-intercept form to represent how much money you make.
Answer:
50=0.75x
Step-by-step explanation:
0.75 is how much each ticket costs.
x is how many tickets
50 dollars is how much you make.
We put 0.75 and x together since they both depend on each other.
y=mx+b
50=0.75x
The equation representing the total money in selling the tickets is
y = 0.75x + 50 where y is the total money and x is the number of tickets sold.
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, you are selling tickets, you make $50 for signing up to sell tickets, and you also make $0.75 for each ticket you sell.
The slope-intercept form of an equation is;
y = mx + c, where m is the slope of the line.
Let y represents the total money earned for selling the tickets and x be the number of tickets sold.
The equation will be;
y = 0.75x + 50, where 0.75x is cost for selling x tickets and 50 is fixed amount.
Hence, The equation representing the total money in selling the tickets is y = 0.75x + 50 where y is the total money and x is the number of tickets sold.

What is the slope of the line?
Write an equation in Ax+By=C form for this line.

Answer:
5x -2y = 30
Step-by-step explanation:
The slope of the line ...
Ax +By = C
is -A/B. This means we can use A=5 and B=-2 in the equation we're looking for. The value of C will be one that makes the equation true at the given point.
5x -2y = 5(4) -2(-5)
5x -2y = 30

The parabola has a minimum value of (1. 5,-1. 5). What is its equation.
The minimum point of a parabola is its vertex.
The equation of the parabola is [tex]\mathbf{y =a(x -1.5)^2 -1.5}[/tex]
The minimum point of the parabola is given as:
[tex]\mathbf{Minimum = (1.5,-1.5)}[/tex]
This represents the vertex (h,k).
So, we have:
[tex]\mathbf{(h,k) = (1.5,-1.5)}[/tex]
A parabola is represented with the following equation
[tex]\mathbf{y =a(x -h)^2 + k}[/tex]
Substitute values for h and k
[tex]\mathbf{y =a(x -1.5)^2 -1.5}[/tex]
Hence, the equation of the parabola is [tex]\mathbf{y =a(x -1.5)^2 -1.5}[/tex], where a does not equal to 0

For each year , the population of a forest of trees is represented by A(t)=115(1.025)t .In a neighboring forest, the population of the same type of tree is represented by the function B(t)=82(1.029)t .
Assuming the population growth models continue to represent the growth of the forests, which forest will have a greater number of trees after 100 years? By how many?
Answer: Forest B has 71 more trees than forest A after 100 years.
Step-by-step explanation:
I'm assuming that both functions should read as follows: (the time, t, is shown as a power, instead as a multiplication).
A(t)=115(1.025)^t
B(t)=82(1.029)^t
Although A starts out with more trees (115), B is growing at 2.9% per year [1.029], versus 2.5% [1.025]for A.
A(100)=115(1.025)^(100)
A(100) = 1359
B(100) = 82(1.029)^(100)
B(100) = 1430
Forest B has 71 more trees than forest A after 100 years.

enter your response here ounces.
(Type an integer or a decimal.)
Using proportions, it is found that the hedgehog loses 3.45 ounces after 115 days of hibernation.
A proportional relationship is modeled by:
[tex]y = kx[/tex]
In which k is the constant of proportionality.
In this problem, the ratio between the weighs loss after x days in hibernation is given by:
[tex]k = \frac{0.24}{8} = \frac{0.84}{28} = \frac{2.25}{75} = \frac{2.79}{93} = 0.03[/tex]
Since this ratio is constant, the relationship is proportional, modeled by:
[tex]y = 0.03x[/tex]
The weight lost after 115 days of hibernation is y(115), hence:
[tex]y = 0.03(115) = 3.45[/tex]
The hedgehog loses 3.45 ounces after 115 days of hibernation.

10x − 10y = –20
–10x + 4y = –16
Step-by-step explanation:
10x - 10y = -20
-10y = -20 - 10x
y = -20/-10 - 10x/-10
y = 2 + x
-10x + 4y = -16
-10x + 4(2 + x) = -16
-10x + 8 + 4x = -16
-6x = -24
x = -24/-6
x = 4
y = 2 + x
y = 2 + 4
y = 6
