Answer:
Y intercept : ( 0 , 25 )
Step-by-step explanation:
Answer:
(0, 25)Step-by-step explanation:
We need to convert function to slope-intrcept form y=mx+b, where:
-0.4x + 0.05y - 1.25 = 0 {multiply both sides by 20}
-8x + y - 25 = 0 {add (8x+25) to both sides}
y = 8x + 25 ⇒ b = 25
Therefore y-intercept of the line is (0, 25)

Answer:
123.6
Step-by-step explanation:
Find the area of the circle, because the four quarter circles add to one circle. The circle has a diameter of 24, so the area of it is 452.4. The square has an area of 24*24, so the area is 576. Subtract the area of the circle from the square, and you get 123.6. Hope this helps!

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.

When Martin graduates college, he is gifted $1,200 and puts the money into a savings account that earns 2.2% annual interest. How much money will Martin have in 2 years? How much money will Martin have in 5 years?
Answer:
2 years = 1252.80 5 years =1332
Step-by-step explanation:
1,200 x 2.2% = 26.4
26.40 x 2 = 52.80
1200 + 52.80 = 1252.80
26.40 x 5 =132

x(x+7)=4x+10
then needs to get the normal form of the equation
x= ?, x=?
Answer:
x = - 5, x = 2
Step-by-step explanation:
Given
x(x + 7) = 4x + 10 ← distribute left side
x² + 7x = 4x + 10 ( subtract 4x + 10 from both sides )
x² + 3x - 10 = 0 ← in standard form
(x + 5)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 2 = 0 ⇒ x = 2

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
0 -4
1 -1
2 2
These values represent points on the graph of the equation y = 3x - 4.

Answer:
36
Step-by-step explanation:
8x + 4 = 4x + 20
8x - 4x = 20 - 4
4x = 16 divide both sides by 4
x = 4 and JM = 8x + 4 replace x with 4
8×4 + 4 = 36
Answer:
36
Step-by-step explanation:
8x + 4 = 4x + 20 ( being opposite sides of parallelogram)
8x - 4x = 20 - 4
4x = 16
x = 16 / 4
x = 4
JM = 8x + 4
=8 * 4 + 4
= 32 + 4
= 36

Answers:
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.
