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

Step-by-step explanation:
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
Solution = (4,6)

The table shows the proportional relationship between a hedgehog's weight loss and the number of days of hibernation. How much weight does the hedgehog lose during 115 days of hibernation?

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.

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.

1. Negative one plus double a number totals nine.
2. Four equals the difference of eight and a number and the result is divided by four.
3. The difference of half of a number and three is equivalent to negative five.
Step-by-step explanation:
1.
-1 + 2x = 9
to get the solution
2x = 10
x = 5
2.
4 = 8 - x
x = 8 - 4 = 4
x/4 = 1
we could also write this
4 = 8 - x | /4
1 = 2 - x/4
x/4 = 1
x = 4
3.
x/2 - 3 = -5
to solve
