Write in point slope form the equation of a line that has the slope of -4 and the passes
through the point (2,2)
Answer:
point slope form is below. since you have the slope already, all you have to do is plug in the point for x1 and y1 and then the slope for m
y - y1 = m(x -x1)
y - 2 = -4 (x - 2) (this is the equation)

What is the answer? 2c-5 C=4
Answer:
2(4)-5=3
we know that C is going to be multiplied by 2 and the value of C=4
so 2*4 = 2(4)
2(4)-5
2*4=8
8-5=3
So, the answer is 3

Which is the graph of the linear inequality x – 2y > –6?
Answer:
uhhh d????
Step-by-step explanation:
Graph D represents the linear inequality x – 2y > –6.
The given inequality is x – 2y > –6.
We rearrange the inequality as y < (1/2)x + 3
Now we have the inequality in slope-intercept form, y < mx + b, where m is the slope (1/2) and b is the y-intercept (3).
To graph this inequality, you can start by plotting the y-intercept, which is the point (0, 3).
The slope of the graph is 1/2.
However, the inequality is y < (1/2)x + 3, which means the shaded region is below the line.
Hence, graph D represents the linear inequality x – 2y > –6.

In 2007, the population of Ecuador was estimated at
13.8 million, with an annual growth rate of 1.6%. If this
rate continues, estimate when the population will reach
15 million.
Answer:
In 2012 , the population will be 15 million
Step-by-step explanation:
We start by setting up an exponential equation that defines the increase
P(t) = I(1 + r)^t
P(t) represents the present population = 15 million
I is the population in 2007 which is 13.8 million
r is 1.6% = 0.016
t is what we want to calculate
15 million = 13.8 million (1 + 0.016)^t
15/13.8 = (1.016)^t
1.09 = (1.016)^t
ln 1.09 = t ln 1.016
t = ln 1.09/ln 1.016
t = 5.429 which is approximately 5
So in 2007 + 5 = 2012, the population will be 15 million

Reagan and Nathan are 40 miles apart on a bike trail when they start pedaling toward each other on their b bicycles. Reagan rides at a constant speed of 8 miles per hour, and Nathan rides a constant speed of 10 miles per hour. How long does it take until Reagan and Nathan meet?
Answer:
They meet in 2.22 hours.
Step-by-step explanation:
We can find the time at which Reagan and Nathan meet by equaling the time as follows:
[tex] v_{R} = \frac{x_{R}}{t} [/tex]
[tex] x_{R} = v_{R}t [/tex] (1)
[tex] v_{N} = \frac{x_{N}}{t} [/tex]
[tex] x_{N} = v_{N}t [/tex] (2)
Where R is for Reagan and N for Nathan.
Knowing that:
[tex] x_{R} + x_{N} = 40 mi [/tex]
By adding equations (1) and (2) we have:
[tex] x_{R} + x_{N} = v_{R}t + v_{N}t [/tex]
[tex] t = \frac{x_{R} + x_{N}}{|v_{R}| + |v_{N}|} = \frac{40 mi}{8 mi/h + 10 mi/h} = 2.22 h [/tex]
Therefore, they meet in 2.22 hours.

En una panadería se elaboraron 140 panes diarios, el 25% son conchas, 10% cortadillos, 40% donas y 25% bolillos. Cada pieza de pan tiene un costo de $8 pesos. ¿Cuanta ganancia se obtuvo en la venta de donas?, ¿Y cuanta ganancia se obtuvo en la venta de bolillos ?
Answer:
Se obtuvo $ 448 de ganancia por la venta de donas.
Se obtuvo $ 280 de ganancia por la venta de bolillos.
Step-by-step explanation:
1) ¿Cuanta ganancia se obtuvo en la venta de donas?
La ganancia es el producto del porcentaje producido de donas, expresado como razón, el precio unitario de la dona y el total producido de panes. Es decir:
[tex]C = \frac{40\,donas}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{dona} \right)[/tex]
[tex]C = 448\,USD[/tex]
Se obtuvo $ 448 de ganancia por la venta de donas.
2) ¿Cuanta ganancia se obtuvo en la venta de bolillos?
La ganancia es el producto del porcentaje producido de bolillos, expresado como razón, el precio unitario del bolillo y el total producido de panes. Es decir:
[tex]C = \frac{25\,bolillos}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{bolillo}\right)[/tex]
[tex]C = 280\,USD[/tex]
Se obtuvo $ 280 de ganancia por la venta de bolillos.
In this exercise we have to use the knowledge of finance to calculate the profit.
1) $ 448 profit was made from donut sales.
2) A profit of $ 280 was obtained from the sale of cupcake.
1)The profit is the product of the percentage produced of donuts, expressed as a ratio, the unit price of the donut and the total produced of breads. That is to say:
[tex]C= (\frac{40}{100} )*(140)*(8)= 448 USD[/tex]
$ 448 profit was made from donut sales.
2) The profit is the product of the percentage of cupcake produced, expressed as a ratio, the unit price of the cupcake and the total amount of bread produced. That is to say:
[tex]C= (\frac{25}{100}) *(140)*(8)= 280 USD[/tex]
A profit of $ 280 was obtained from the sale of cupcake.

What is the graph of y = 3jx|?
Ο Α.
5
>
Note: Your question sounds a little unclear and incomplete. I assume you want to get the idea about the graph of 3|x|. My answer may still clear your concept about the graphs.
Answer:
The graph of y=3|x| is attached below.
Step-by-step explanation:
Given the function
[tex]y=3\left|x\right|[/tex]
Determining the domain:
We know that the domain of a function is the set of input or argument values for which the function is real and defined.
The function has no undefined points nor domain constraints. Therefore, the domain is:
[tex]-\infty \:<x<\infty \:[/tex]
Determining the range:
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.
[tex]\mathrm{The\:range\:of\:an\:absolute\:function\:of\:the\:form}\:c|ax+b|+k\:\mathrm{is}\:\:f\left(x\right)\ge \:k[/tex]
[tex]k=0[/tex]
[tex]f\left(x\right)\ge \:0[/tex]
Thus,
[tex]\mathrm{Range\:of\:}3\left|x\right|:\quad \begin{bmatrix}\mathrm{Solution:}\:&\:f\left(x\right)\ge \:0\:\\ \:\mathrm{Interval\:Notation:}&\:[0,\:\infty \:)\end{bmatrix}[/tex]
Determining the x-intercept and y-intercept:
From the graph, it is clear that at x=0, y=0. Therefore, the y-intercept is (0, 0)From the graph, it is clear that at y=0, x=0. Therefore, the y-intercept is (0, 0)The graph of y=3|x| is attached below.

SAS Similarity Theorem C. SSS Similarity Theorem D. Any of the above could be used to show that the triangles are similar.
Answer:
1) Please find attached the given plot and sketch of the points created with Microsoft Word
2) The correct option is;
A. AA Similarity Postulate
Step-by-step explanation:
1) Please find attached the given plot and sketch of the points created with Microsoft Word
2) The given parameters are;
The coordinates of the points are A(0, 0), B(1, 0), C(1, 2), D(2, 0) and E(2, 4)
Therefore, we have;
The length of segment AB = 1
The length of segment BC = 2
The length of segment AD = 2
The length of segment DE = 4
Therefore, we have;
∠ABC = ∠ADE = 90°
∠BAC = = artctan(2/1) = ∠DAE = artctan(4/2) = 63.435°
Therefore, ΔABC and ΔADE are similar by AA Similarity Postulate

If it is not a perfect square, find the perfect square that seems “closest” to the given expression and show how the perfect square can be adjusted to be the given expression.
1. A(x)=x^2+6x+13
2. A(x)=2x^2+8x+14
Step-by-step explanation:
These aren't a perfect square bec. 1 st and 3rd terms must be perfect square
A(X) = X^2+6X +13 be perfect square if 13 Changed to 9
= X ^2+6X +9
A(x)= 2X^2+8X +14 be perfect square
= 4X ^2+ 8X + 16
