5x=y is it Proportional or not and if it is proportional whats the constant proportionality
Answer:
Yes, 5x = y is Proportional and, the constant of proportionality is 5
Step-by-step explanation:
If x and y are proportion, then
y = k x is the equation of the proportional, where k is the constant of proportionalityIt represented graphically by a line passes through the origin (0, 0)∵ 5x = y
→ Switch the two sides
∴ y = 5x
→ Check it if passes through the origin point or not
∵ At x = 0, y = 5(0) = 0
∴ (0, 0) is a point ∈ y = 5x
∴ y = 5x represented graphically by a line passes through the origin
∴ x and y are proportion
∴ y = 5x is the equation of proportional
→ By comparing it with the form of the equation above
∴ k = 5
An initial investment of $500 is made in an account which earns 6% interest compounded
semiannually. Which of these equations gives the value of the investment after t years?
Answer:
A = 500(1+6%/2)^2t
Step-by-step explanation:
Given the general compound interest formula A = P(1+r/n)^nt. With an initial investment of $500, and percent interest of 6% compounded semi annually(every six months/half a year/twice in one year). A = 500(1+6%/2)^2t .
i.e if given two years of compound interest, t=2. A = 500(1+6%/2)^2(2), 500(1+0.03)^4, 500(1.03)^4, 500(1.12550881), 500(≈1.1255) = 562.75
A = 562.75$ for two years

What is an equation of the line that passes through the points (0, 3) and (5,-3)?
Put your answer in fully reduced form.
Answer:
The equation of the line that passes through the points (0, 3) and (5, -3) is [tex]y = -\frac{6}{5}\cdot x +3[/tex].
Step-by-step explanation:
From Analytical Geometry we must remember that a line can be formed after knowing two distinct points on Cartesian plane. The equation of the line is described below:
[tex]y = m\cdot x + b[/tex] (Eq. 1)
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]m[/tex] - Slope, dimensionless.
[tex]b[/tex] - y-Intercept, dimensionless.
If we know that [tex](x_{1},y_{1}) = (0,3)[/tex] and [tex](x_{2},y_{2})=(5,-3)[/tex], the following system of linear equations is constructed:
[tex]b = 3[/tex] (Eq. 2)
[tex]5\cdot m + b = -3[/tex] (Eq. 3)
The solution of the system is: [tex]b = 3[/tex], [tex]m = -\frac{6}{5}[/tex]. Hence, we get that equation of the line that passes through the points (0, 3) and (5, -3) is [tex]y = -\frac{6}{5}\cdot x +3[/tex].

6. mZ1 = (3x + 10)
m24 = (4x - 15)
What is the m<7?
Answer:
95°
Step-by-step explanation:
1 is opposite to 4. So, (3x+10)° = (4x-15)°
3x + 10 = 4x - 15
10 + 15 = 4x - 3x
25 = x
m(4) = 4x - 15 => 4.25 - 15
100 - 15 = 85 = m(4)
7 is opposite to 6 and 6 is parallel to 4. So, m(4) + m(6) = 180°
85° + m(6) = 180°
m(6) = 95°
6 is opposite to 7, so m(6)=m(7) and answer is 95°

The sum of three numbers is 123. The second number is 9 less than two times the first number. The third number is six more than three times the first number. Find the three numbers
Answer:
21, 33 and 69Step-by-step explanation:
x - the first number
2x - two times the first number
2x-9 - 9 less than two times the first number = the second number
3x - three times the first number
3x+6 - six more than three times the first number = the third number
The sum of three numbers is 123:
x + 2x-9 + 3x+6 =123
6x - 3 = 123
6x = 126
x = 21
2x-9 = 2•21-9 = 33
3x+6 = 3•21+6 = 69
Check: 21+33+69 = 123

-2
Answer:
y intercept is -2.
Step-by-step explanation:
Convert the equation to slope-intercept form, or in other words, isolate the y variable. You should get y=(7/4)x-2. the -2 is the y intercept.

To solve one-step equations, we do the inverse (opposite) of whatever operation is being performed on the variable, so we get the variable by itself. The most important thing to remember is that whatever you do to one side of the equation, you have to do the same thing to the other side. 5 + y = 7
Answer:
[tex]y = 2[/tex]
Step-by-step explanation:
Given
[tex]5 + y = 7[/tex]
Required
Solve
From the analysis attached to the question, we can solve this equation by subtracting 5 from both sides:
[tex]5 + y = 7[/tex]
[tex]-5 + 5 + y = 7 - 5[/tex]
[tex]0 + y = 2[/tex]
[tex]y = 2[/tex]

help!!! I don't know this
Answer:
Graph C
The Y axis is up and down and the x axis is side to side. So first we want to look to see which line crosses the y axis the the up and down black line.
When you are finding a coordinate you set it up like this (x, y). You will find x first and y second.
So we are down to two graphs graph a and graph c. Know both of them cross at the (0,-7) mark but it asks for one other thing a well.
On a graph when something decreases it will go down and when something increases it will go up. So that tells me it is graph C.

What is the slope of the line shown on the graph to the right?
The slope of the line is .....................
Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 8, 0) and (x₂, y₂ ) = (4, 6) ← 2 points on the line
m = [tex]\frac{6-0}{4+8}[/tex] = [tex]\frac{6}{12}[/tex] = [tex]\frac{1}{2}[/tex]

Sound policy requires that a certain number of trees be planted for every tree that is cut down for example of 8 trees are cut down 48 trees will be planted a homeowner is going to cut down five trees on his property how many trees will be planted 1/5 are cut down
Answer:
30 trees
Step-by-step explanation:
Given the policy:
8 trees are cut down 48 trees will be planted
If homeowner is going to cut down five trees on his property how many trees will be planted
Since :
8 trees cut down = 48 planted
5 trees cut down = X
Cross multiply :
8 * X = 48 * 5
8X = 240
X = 240/8
X = 30
Hence, 30 trees will need to be planted
Answer: 30

Answer:
y=640-3x
Step-by-step explanation:
The total amount of ounces in the bucket is 640, and it decreases by 3 each minute. For example, if you plug in 3 for x into that equation (which would represent 3 minutes), you would lose 9 ounces of water, which makes sense in the terms of the equation.
