A linear relationship is given in the table.
x −2 −1 0 1 2
y −18 −12 −6 0 6
What is the slope of the relationship?
−6
negative one sixth
one sixth
6
Is the linear relationship also proportional? Explain.
No, the constant of proportionality is 2.
Yes, the constant of proportionality is 2.
No, there is no constant of proportionality.
Yes, there is no constant of proportionality.
Step-by-step explanation:
To find the slope
m = ∆y/∆x
m = (6 -0)/(2-1)
m = 6/1= 6
hence the slope is 6
now the other question
y = m(x -x1) +y1
y = 6(x - 1) +0
y = 6x -6
none of the options are right.
Answer:
Step-by-step explanation:
To find the slope of the linear relationship, we need to use the formula:
slope = (change in y) / (change in x)
We can choose any two points from the table to find the change in y and change in x. Let's choose the points (A1 ,B1)=(-1, -12) and (A2,B2)= (1, 0):
change in y =(B2-B1)= 0 - (-12) = 12
change in x =(A2-A1)= 1 - (-1) = 2
slope = change in y / change in x = 12 / 2 = 6
Therefore, the slope of the relationship is 6.
To determine if the linear relationship is also proportional, we need to check if the ratio of y to x is constant for all pairs of x and y in the table. calculate the ratios for each pair of x and y:
-2: -18/-2 = 9
-1: -12/-1 = 12
0: -6/0 (undefined)
1: 0/1 = 0
2: 6/2 = 3
We can see that the ratios are not constant, so the linear relationship is not proportion
There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish
Hope you understood the answer and I hope it helps you :)

The base of this pyramid is a rectangle. How many congruent faces does this pyramid have?
The pyramid has 4 congruent faces.
The pyramid has 5 congruent faces.
The pyramid has 1 pair of congruent faces.
The pyramid has 2 pairs of congruent faces.
Answer: The Pyramid has 2 pairs of congruent faces
Step-by-step explanation:
The explanation of congruent is the face has the same shape and same size. On rectangle pyramid, the height triangle are 2 same faces and 2 same faces, so it has 2 pairs of congruent faces

Zach keeps his pet chameleon Pinky in a terrarium with the dimensions shown below. There's sand in the bottom of the terrarium that reaches a height of 8 centimeters. Zach gets a new terrarium for Pinky that is larger. The base of the new terrarium is 25 by 64 centimeters. Zach moved the existing sand to the new terrarium.
Answer:
5cm
Step-by-step explanation:
50cm x 20cm x 8cm = 8000cm^3
25cm x 64cm = 1600cm^2
1600x=8000
x=5cm

3 x 3 x 3 x 3 written using exponents
Answer: 3^4
3 ^ 4
3 is the number being multiplied
the ^ indicates that the number to the left of it is being multiplied by itself, and the number to the right indicates how many times the number on the left is being multiplied by itself.
Since 3x3x3x3 is just multiply 3 by itself 4 times, 3^4 = 3x3x3x3
The given numerical expression is expressed in exponential form as \(3^4\).
Given that, 3 × 3 × 3 × 3.
What is the exponent?Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself.
We know that, a × a = a²
Now, 3 × 3 × 3 × 3 = \(3^4\)
Hence, the given numerical expression is expressed in exponential form as \(3^4\).

Given the equation A=250(1.1)^t, you can determine that the interest is compounded annually and the interest rate is 10%. Suppose the interest rate were to change to being compounded quarterly. Rewrite the equation to find the new interest rate that would keep A and P the same. What is the approximate new interest rate?
Convert your answer to a percentage, round it to the nearest tenth, and enter it in the space provided, like this: 42.53%
Answer: 2.5%
Step-by-step explanation:
Hi, to answer this question we have to apply the compounded interest formula:
A = P (1 + r/n) nt
Where:
A = Future value of investment (principal + interest)
P = Principal Amount
r = Nominal Interest Rate (decimal form, 10/100= 0.1)
n= number of compounding periods in each year (365)
Replacing with the values given
A=250(1+0.1/1)^t/1
A=250(1.1)^t
For a interest compounded annually, n=1, compounded quarterly n= 4 (4quarters in a year )
Interest rate 0.1 /4 = 0.025= 2.5%

9.6%

Answer:
you can basically graph different points to form a decagon so you can have a 10 point combination and then say the order you went in.
Step-by-step explanation:
Directions: Follow the instructions for the following inequalities.
1. 4 < 7 Multiply both sides by 3, then by 2, then by 4, then by 9
2. 11 > -2 Add 3 to both sides, then add 3, then add (-4)
3. -2 less than or equal to -2 Subtract 6 from both sides, then 8, and then 2
4. -4 < 8 Divide both sides by -4, then by -2
5. Write a short explanation of the effects of the above operations. Did this affect the inequality sign? Was it still true? Why or why not?
Answer:
1. 504 < 1512
2. 12 > 0
3. -2 = -2
4. -1 < 2
Step-by-step explanation:
Given that both sides are being changed by the same amount and sign, the sign never changes. They always have the same value.
6^{2} + b^{2} = 8^{2}
Answer:
-{2√7} or {2√7}
Step-by-step explanation:
1) Simplify the exponents 6^2 and 8^2 by multiplying 6*6=36 and 8*8=64.
2) Write an equation, 36+b^2=64
3) Subtract 36 from both sides, b^2=28
4) Apply a square root to both sides, √(b^2)=√(28)
5) Simplify the equation, b=-√(28) or b=√28
6) If you want, factor the square root by finding a factor that is a square number, -{√(4)*√7} or {√(4)*√7}; -{2√7} or {2√7}
