Answer:
two unequal, complex roots
Step-by-step explanation:
Rewrite this quadratic as a^2 + 3a - 7 = 0. The coefficients are {1, 3, -7}. The discriminant is b^2 - 4ac = 3^2 - 4(1)(-7), or 9 - 28, or -19.
Because the discriminant is negative, we know immediately that this quadratic has two unequal, complex roots.

Is y=x^2+7 a linear equation?
Answer:
No, it is not a linear equation
Step-by-step explanation:
This equation contains the term x², meaning that it is a quadratic function (parabola)
So, it is not a linear equation.
If it were a linear equation, x would not be squared, and the equation would have been in y = mx + b form.
The answer is no, it is not a linear equation.
Answer:
Given :-[tex] \large \sf \bullet \: y = {x}^{2} + 7[/tex]
To Find :-Is it a linear Equation
Solution :-We may notice that
x has power as 2.
So,
We know that
A linear Equation doesn't consist of power. Linear equation only consist of variable and constant.

Have a common difference Have a common factor Have a linear first difference============================================================
Explanation:
Linear functions, such as y = 2x+5, have a common difference. In that example, the common difference would be 2 since we add 2 to each term to get the next one. Consider when x = 1 and that leads to y = 7. Then when x = 2, we have y = 9. Then when x = 3, we have y = 11, and so on. The sequence of y values {7,9,11,...} shows we add 2 each time.
------------------
Exponential functions have us multiply the previous term by some common factor to get the next term. A sequence like {2,6,18,...} has us multiply by 3 each time and the exponential function modeling this sequence is y = 2(3)^(x-1) where x is a natural number. So this is an example showing that exponential functions have a common factor, or we can call this a common ratio.
------------------
Quadratic functions are a bit strange.
Let's consider the quadratic of y = x^2. The sequence of y values it generates is {1,4,9,16,25...} for positive integers x = 1, 2, 3, 4, 5....
Let's subtract the adjacent terms (larger - smaller)
4-1 = 39-4 = 516-9 = 725-16 = 9Note the results of 3,5,7,9 are in a linear sequence (we're adding 2 to each increment value, so the next increment would be +11). We can consider this a linear first difference.
------------------
For any of these functions, I'm restricting x to be an integer and x = 1 is the smallest input possible.

Step-by-step explanation:
Cuatro meses después que se detuviera la publicidad, una compañia fabricante notifica que sus ventas han caido de 100.000 unidades por mes a 80.000. Si las ventas siguen un patron de decrecimiento exponencial, cuantas unidades habra despues de los siguientes dos meses?
Answer:
51,200 unidades
Step-by-step explanation:
Paso 1
Calculamos el porcentaje de disminución
= 100000 - 80000/100000 × 100
= 20000/100000 × 100
= 20%
Por lo tanto, el porcentaje de disminución cada mes = 20%
Paso 2
La fórmula de la disminución exponencial
y = a (1 - r) ^ t
a = 80.000
r = 20% = 0,2
t = tiempo en meses = 2
y = 80000 (1 - 0,2) ^ 2
y = 51.200 unidades
Usando una función exponencial, se encuentra que habra 71.554 unidades despues de los siguientes dos meses.
Una función exponencial decreciente tiene el siguiente formato:
[tex]A(t) = A(0)(1 - r)^t[/tex]
En que:
A(0) es la cuantia inicial.r es la tasa de desintegración.En este problema:
Inicialmente, 100000 unidades por mes, o sea, [tex]A(0) = 100000[/tex].Cuatro meses después, 80000 unidades por mes, o sea, cuando [tex]t = 4, A(t) = 80000[/tex], e esto es usado para encontrar r.[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]80000 = 100000(1 - r)^4[/tex]
[tex](1 - r)^4 = 0.8[/tex]
[tex]\sqrt[4]{(1 - r)^4} = \sqrt[4]{0.8}[/tex]
[tex]1 - r = 0.945742[/tex]
Por eso:
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]A(t) = 100000(0.945742)^t[/tex]
Apos el siguinte dos meses, hay el mes 6, por eso:
[tex]A(6) = 100000(0.945742)^6 = 71554[/tex]
Habra 71.554 unidades despues de los siguientes dos meses.

1/3 is not equivalent to 1/2 or 2/5.

On the number line, which point is the closest pi .
A.
B.
C.
D.
The closest point to the number line is C.
Hence Option C is correct.
In the given number line
There are 10 equidistant points between 3.1 and 3.2
So, the set of points shown on the line is,
{3.1, 3.11, 3.12, 3.13, 3.14, 3.15, 3.16, 3.17, 3.18, 3.19, 3.2}
Therefore,
Point c represents point 3.14 approximately.
Since we know that π is an irrational number,
So it is non-terminating and non-repeating but for approximation,
π = 22/7
π ≈ 3.142
Hence,
The point C is very close to the π.

The completed table of values for the equation y = 3x - 4 includes the following points: (-2, -10), (-1, -7), (0, -4), (1, -1), and (2, 2). These points represent the corresponding values of y when different values of x are substituted into the equation.
To complete the table of values for y = 3x - 4, we can assign different values to x and calculate the corresponding values of y. Let's choose a few values for x and find the corresponding y-values:
x y = 3x - 4
-2 -10
-1 -7
0 -4
1 -1
2 2
By substituting these x-values into the equation y = 3x - 4, we can calculate the corresponding y-values. Therefore, the completed table of values for the given equation is:
x y = 3x - 4
-2 -10
-1 -7
