Complete the point-slope equation of the line through (-4, 8) and (4, 4).
Use exact numbers.
Answers
Answer:
y-4 = -1/2(x-4)
Step-by-step explanation:
Point slope form is y-y1 = m*(x-x1)
To find m, m=(y2-y1)/(x2-x1)
m=(4-8)/(4-(-4)) = -4/8 = -1/2
The equation is, y-4 = -1/2(x-4)
The equation of line is, [tex]y=-\frac{1}{2} x+6[/tex]
The equation of line is given in slope point form is,
[tex]y=mx+c[/tex] , where m is slope of line.
[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{4-8}{4+4}=\frac{-4}{8}=-\frac{1}{2}[/tex]
So, equation of line become,
[tex]y=-\frac{1}{2}x+c[/tex]
Since, above line passing through point (4, 4)
So that,
[tex]4=-\frac{1}{2}*4+c\\\\c=4+2=6[/tex]
Hence, equation of line is, [tex]y=-\frac{1}{2} x+6[/tex]

Answer:
1.
as we can see in the first fraction, they are multiplying the denominator by 5 to get from a denom of 20 to 100. THerefore, we can now multiply the num of 17/20 by 5 to get our answer. 17x5=85
85/100 can be written as .85.
THe answer is 85
2.
By folowing the same proccess we see that the denom in being multiplied by 2 and therefore by doing the ssame with the num we get 62. 62/100 is 0.62. To find this you can divide 62 by 100 or just know that any number over 100 is the decimel. For example in the fraction 76/100 0.76 is the decimal.
62

Los talleres gráficos "La imprenta" están modificando los salarios de sus empleados. La administración está considerando dos planes, ambos con base en un salario fijo más una comisión en porcentaje por venta al menudeo. El plan A es de $300 de salario más 6% de ventas, y el plan B es de $150 de salario más 10% de ventas. ¿Para qué nivel de ventas serán iguales los planes? Traza en tu libreta la gráfica. LA RESPUESTA SOLAMENTE SE CONSIDERARA COMO CORRECTA SI SE REDACTA COMO LA ESTRUCTURA DEL SIGUIENTE EJEMPLO: $5600.
Answers
Responder:
$ 3750
Explicación paso a paso:
Dado que :
Los planes A y B se basan en un salario fijo más el porcentaje de comisión por venta minorista.
Plan A:
Salario fijo = $ 300
Comisión porcentual = 6% de la venta
Plan B:
Salario fijo = $ 150
Comisión de porcentaje = 10% de la venta
Nivel de venta en el que el plan será el mismo:
Sea nivel de venta = x
Ganancia total por plan:
Plan A:
300 + 0.06x - - - (1)
Plan B:
150 + 0,1x - - - (2)
Igualar (1) y (2)
300 + 0.06x = 150 + 0.1x
0.06x - 0.1x = 150 - 300
-0.04x = - 150
x = 150 / 0,04
x = 3750
Por lo tanto, el nivel de venta en el que ambos planes serán iguales es una venta minorista por valor de $ 3750

The population of a certain species of oak tree in a national forest declines each year by one-fourth. So, after each year, only three-fourths of the trees present at the beginning of the year remain.
Which of the following describes the rate of decline in the population of the species of oak tree?
Answers
Answer: 25%
Step-by-step explanation: The question tells us that the population decreases by 1/4 every single year. That means, since 1/4 equals .25, the population decreases by 25% every year :)

Let a and b be real numbers where a ≠ b ≠ 0. Which of the following functions could represent the graph below?
Answers
Answer:
b.
Step-by-step explanation:
The correct function of the graph is,
⇒( f(x) = (x-a)²(x-b)⁴
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Now, Clearly from the graph of the function we could see that zero is not a root of the polynomial function
Hence, option (a) and (c) are discarded.
Now, we will check for option (b) and option (d)
As the graph touches the x-axis at two point i.e. a and b that means that both the roots of the polynomial equation are of even degree.
Hence, the correct option is:
⇒ f(x) = (x-a)²(x-b)⁴

Which of the following notations correctly describe the end behavior of the
polynomial graphed below?
Answers
Answer: Option B.
Step-by-step explanation:
In the graph we can see the graph of a quadratic equation (from this we could conclude that the graph will not change the current direction for the arms, so the arms will keep going down), and we also can see that as x increases in absolute value, the value of y decreases.
Then we could conclude that as IxI is really big, we will have that f(x) goes to minus infinity
x -->∞, f(x) --> -∞
x--> -∞, f(x) --> -∞

Willis analyzed the following table to determine if the function it represents is linear or non-linear. First he found the differences in the y-values as 7 – 1 = 6, 17 – 7 = 10, and 31 – 17 = 14. Then he concluded that since the differences of 6, 10, and 14 are increasing by 4 each time, the function has a constant rate of change and is linear.

y=88 and x=23 because 4x=3x+23 and y+4x=180
Answer:
x = 23
y = 88
Step-by-step explanation:
because they are parallel lines 3x + 23 = 4x
So you subtract 3x from both sides to get 23 = x
now because you have this and y + 4x = 180
4(23) = 92
180 - 92 = 88
y = 88
