Answer:
The constant of proportionality is 1/4.
Step-by-step explanation:
Keep in mind that the constant of proportionality can always be found by dividing any y value by any x value, as long as the values are in the same row. For example, in this table, the constant of proportionality would be 1/4, as, in the first row, the y value is 2 and the x value is 8, and 2/8 equals 1/4.

What can you multiply to get to 3 and add up to 4
Write 4:20 in the simplest form
Answers
Answer:
1:5
Step-by-step explanation:
To write 4: 20 in simplest form we have to find the GCF (Greatest common factor)
The GCF of 4 and 20 is 4.
we need to factor each number
(factors of 4 = 1, 2, 4)
(factors of 20 = 1, 2, 4, 5, 10, 20)
and choose the greatest factor that exactly divides both 4 and 20, i.e., 4.
Now we can divide
4: 4 = 1
20 : 4 = 5
Thus, 4: 20 in simplest form is 1:5
[RevyBreeze]
Answer:
1:5
Step-by-step explanation:
4:20 also can be express as 4/20 {fraction}
Find GCF : 4
Thus,
4/4 = 1
20/4 = 5
we can also see that if we cross multiply:
4 × 5 = 20
20 × 1 = 20
[tex]\frac{4}{20}=\frac{1}{5}[/tex]
Therefore, 4:20 in the simplest form is 1:5 or 1/5

y=4 times 1/2 to the power of x
i need help putting it into a table
Answers
Answer:
Step-by-step explanation:
y=4 times 1/2 to the power of x can be written symbolically as
4 4
y = 4(1/2)^x. This is the same as y = ------- or y = -------- * 2^(-x)
2^x 1
This function is a "decaying exponential."
A suitable table follows:
x 4(2^[-x]) x y
0 4(2^0) (0, 4)
1 4(2^1) (1, 8)
2 4(2^2) (2, 16)
and so on.
Write an equation of the line that passes through the points (-4, -2) and (0,6)
Answers
Answer:
y= 2x +6
Step-by-step explanation:
Slope-intercept form
y= mx +c, where m is the slope and c is the y-intercept.
[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]
Slope
[tex] = \frac{6 - ( - 2)}{0 - ( - 4)} [/tex]
[tex] = \frac{6 + 2}{0 + 4} [/tex]
[tex] = \frac{8}{4} [/tex]
= 2
y= 2x +c
y-intercept occurs at x= 0. Since we are given that the line passes through the coordinates (0, 6), the y-intercept is 6.
Thus, the equation of the line is y= 2x +6.

Write out, in paragraph form, a plan for completing the following proof.
For example, will you prove triangles congruent? How? By what theorem?
Given:
AR= AQ
RT=QS
Prove:
Angle RAT = QAS
Answers
Congruent triangles have equal corresponding sides and angles
Angles RAT and QAS are congruent
How to prove that angles RAT and QAS are congruentGiven that:
AR= AQ and RT=QS
Subtract QS from both sides of the second equation
RT-ST=QS-ST
The above equation means that:
RS = QT or
RS = TQ
In triangle ARQ,
Angles R and Q are congruent because the base angles of an isosceles triangle are congruent.
So, we have:
Angle R = Angle Q
Also,
Angle ARS is congruent to ATQ.
The above means that:
Side lengths AT and AS are congruent
So, we have:
AT=AS ---- The base angles of an isosceles triangle ATS
Because of the above highlights,
Angle 1 = Angle 3
Add angle 2 to both sides
Angle 1 + Angle 2 = Angle 3 + Angle 2
So, we have:
Angle RAT = Angle QAS
Hence, angles RAT and QAS are congruent

los 7/9 del sueldo de una persona son 280 dolares ¿cual es el sueldo de la persona,
Answers
Answer:
$360
Step-by-step explanation:
El sueldo de la persona es igual a un monto de $360
Si tenemos un número y queremos determinar una fracción de este entonces debemos multiplicar la fracción por el número recordando que en la multiplicación de fracciones se obtiene una fracción con numerador la multiplicación de los numeradores y con denominador la multiplicación de los denominadores (si es solo un número entero su numerador es el entero y su denominador es 1), luego se simplifica de manera de obtener una fracción irreductible (fracción donde el numerador y el denominador no tengan términos en común)
Los 7/9 del sueldo es $280, entonces si el sueldo es "x" tenemos que:
7/9*x = $280
x = $280*9/7 = $2520/7
x = $360

Answers
Answer:
x = -6
y = -16
Step-by-step explanation:
if you subtract the two equations from each other then the 'y' terms will be eliminated:
2x = -12
x = -6
solve for 'y':
4(-6) - 3y = 24
-24 - 3y = 24
-3y = 48
y = -16
4x-3y=24
2x=-12
x=-6
6(-6)-3y=12
-36-3y=12
-3y=48
y=-16
Answer: x=-6, y=-16

Which system of equations could be graphed to solve the equation below? log Subscript 0. 5 Baseline x = log Subscript 3 Baseline 2 x.
Answers
You can use the fact that two expressions in equality can be considered to be equal to a third variable(not used in given context).
The system of equations that could be graphed to solve the equation given is
[tex]y = \log_{0.5}(x)\\\\[/tex][tex]y = \log_3(2+x)[/tex]How can we form a system of equations from an equation?Suppose the equation be [tex]a = b\\[/tex]
Let there is a symbol [tex]c[/tex] such that we have [tex]a = b = c[/tex]
It is because a and b are same measure (that is exactly what a = b means)
and we gave another name c to that measure.
Thus, we have
[tex]a = c\\b = c[/tex]
in addition to [tex]a = b\\[/tex]
Using the above method to find the system of equations neededSince the given equation is [tex]log_{0.5}(x) = log_2(2+x)[/tex]
The 2d graphs are usually expressed as [tex]y = f(x)[/tex] on X-Y plane.
Taking the equation's expressions equal to y, we get
[tex]log_{0.5}(x) = log_2(2+x) = y[/tex]
or, we get system of equations as
[tex]y = log_{0.5}(x)\\\\y = log_3{(2 + x)}[/tex]
Their graph is plotted below. The intersection point of both curves is the solution to the given equation as it satisfies both the equations of the system of equations formed from the given equation.

What is the rate of the boat in still water and what is the rate of the current?
Answers
Answer: 2mp
Step-by-step explanation: Let "b" represent the speed of the boat in still water
Let "c" represent the speed of the current
Let "t" represent time
Downstream(same direction) =(b+c)*t
Upstream(against current)=(b-c)*t
(b+c)*3=24
(b-c)*4=16
3b+3c=24....all sides can be divided by 3 =b+c=8
4b-4c=16.....all sides can be divided by 4 =b-c=4
Use Elimination method
b+c=8
b-c= 4 Subtracting
=====
2c=4
find c by dividing both sides by 2. c=2
if c=2, substitute to get b
