proportional or not proportional?
Answer:
Proportional
Step-by-step explanation:
The relationship is proportional because starting at (0,0) there's a constant rate between the number of plants and the number of roses. We can represent this proportional relationship as y=5x where k=5, the constant of proportionality.

Solve the system. y = -x + 3 and y = 2x
the solution is (__,__).
Explain your choice of method.
Answer: (1, 2)
which means
x = 1
y = 2
Step-by-step explanation:
y = -x + 3
y = 2x
Because both equations are set equal to y, they can be set equal to each other. The equations are ready to go to use Substitution method.
Substitute.
-x + 3 = 2x
Add x to both sides.
3 = 3x
Divide by 3.
3/3 = x
1 = x
We can put the 1 in for x in either equation.
y = 2x
y = 2(1)
y = 2
Putting x for 1 into the other equation is a good check.
y = -x + 3
y = -1 + 3
y = 2
So the x and y that work in both of these equations is:
x = 1 and y = 2
The form that was asked for was ( , ).
So the answer is
(1, 2).

Write the equation of the line. Giving Brainliest to the fastest and most explanatory answer!
The equation of line shown in figure is,
⇒ y = x - 4
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (4, 0) and (0, -4).
Now,
Since, The equation of line passes through the points (4, 0) and (0, -4).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 4 - 0) / (0 - 4)
m = - 4 / -4
m = 1
Thus, The equation of line with slope 1 is,
⇒ y - 0 = 1 (x - 4)
⇒ y = x - 4
Therefore, The equation of line is,
⇒ y = x - 4

Answer:The mean goes up from approximately 80.4 to 82.
Step-by-step explanation:
Before adding 101°, the mean i2:
(58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57)/12 = 80.4
After adding the value 101°, the mean is:
(58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 + 101)/13 = 82
The mean goes up from approximately 80.4 to 82.

The formula for any geometric sequence is an = a1 · rn - 1 , where an represents the value of the n th term, a1 represents the value of the first term, r represents the common ratio, and n represents the term number. What is the formula for the geometric sequence 4, 8, 16, 32, ...?
A. an = 4 · (1/2) n - 1
B. an = 2 · 4 n - 1
C. an = 32 · 2 n - 1
D. an = 4 · 2 n - 1
Answer: The correct answer would be
D. an = 4.2n-1
Step-by-step explanation: First, calculate the ratios between each term and the one that precedes it.
8/4=2 ....16/8=2...32/16= 2...
Upon comparing the ratios we see the ratio between each term and the one that precedes it is 2 for all the terms, the sequence is geometric, and the common ratio is r = 2.
Now, we simply need to find the other unknown values in the equation, a1= the first term of the sequence which is 4, Therefore a1=4
Looking at the options provided we see that no further missing quantity can further be found so we put this in the equation provided for a geometric sequence.
We get 4. 2n-1, which is our answer.

how many solution does 4x-5(2x+1)=6x+1 have
The number of solution the equation 4x - 5 (2x + 1) = 6x + 1 have is one.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
We have,
4x - 5 (2x + 1) = 6x + 1
4x - 10x - 5 = 6x + 1
-6x - 5 = 6x + 1
-5 - 1 = 6x + 6x
-6 = 12x
x = -6/12
x = -1/2
This means,
The equation has one solution.
Thus,
The equation has one solution.

Answer:
The circumference talks about the outside of the circle. So the formula for the circumference of a circle is 2πr (r stands for radius and π is pi. In this case we use 3.14 for pi).
Since the radius is half of the diameter and we know that the diameter of the trashball is 4 in, we half the 4. So the radius of the trashball is 2 in.
Now plug everything in the formula.
2(3.14)(2) = 12.56.
The circumference of the trashball is 12.56 in.
