Answer:
k = 2
Step-by-step explanation:
y varies directly as x: y = kx (for some constant, k)
when x = 9 and y = 18: 18 = 9k
⇒ 2 = k
Therefore, k = 2

Answer:
The formula for calculating the circumference of a circle is 2*pi*r. Because pi does not have an end, we'll use 3.14, since that is the approximate value of pi.
2*6*3.14 = 37.68
The outer rim of the pool is about 37.68 meters long
Step-by-step explanation:
It’s probably 40 because it says about how long not exactly.
I hope this helped
Answer:
40m
Detailed explanation of answer:
Finding the length of the outer rim can be determined using the circumference of a circle formula. Since the rim is circular.
Therefore:
length of outer rim= 2πr
where its r is slightly larger than the radius of the pool
= 2 X ²²/7x 6
= 37.714metres
which is approximately 40m

What is the probability of rolling a three on one dice and rolling a two on a second dice
Answer:
1/36
Step-by-step explanation:
Rolling a three on a six-sided die is 1/6.
Rolling a two on a six-sided die is 1/6.
you multiply 1/6 and 1/6 to find the total probability.
1/6 x 1/6 = 1/36

I dont know the answer to this question I dont know what I can put for the x and the y
Answer:
(x, y) = (-4, 4)
Step-by-step explanation:
You find the values of x and y by working the problem using any of the methods of solving simultaneous equations that you have been taught.
Here, you observe that the y-coefficients are the same in each equation. That means you can cancel the y-terms by subtracting one equation from the other.
(7x +6y) -(4x +6y) = (-4) -(8)
3x = -12 . . . . simplify
x = -4 . . . . . . divide by 3
Now, you can substitute this into either equation to find y.
4(-4) +6y = 8
6y = 24 . . . . . . . . add 16
y = 4 . . . . . . . . divide by 6
The solution to this system of equation is ...
x = -4y = 4Answer:
x = -4y = 4Solution:
=> 7x + 6y = -44x + 6y = 8
=> 3x = -12=> x = -4Now, let's substitute the value of x into an equation to find the value of y.
7x + 6y = -4=> 7(-4) + 6y = -4=> -28 + 6y = -4=> 6y = -4 + 28=> 6y = 24=> y = 4Let's check our answer using the second equation.
Check:
4x + 6y = 84(-4) + 6(4) = 8=> -16 + 24 = 8=> 8 = 8Hence, this is proven correct.

Without solving the system determine whether there are 0,1 or an infinite number of solutions explain how you know
Answer:
Its infinite many solutions. Multiply each by 1.5 to get the next.
Step-by-step explanation:
Just by looking at this we can see that to get each variable to the next,
for example 3x to 4.5/ 2y to 3y/ or 8 to 12--- we can see that each only needs to be multiplies by 1.5. This means they are the same equation.

If f(x) = 5x + 40, what is f(x) when x = -5?
+
Answer:
15
Step-by-step explanation:
When you are evaluating a function for a particular value of the variable, put that value everywhere you see the variable. Then simplify.
f(x) = 5x +40
When x = -5, this becomes ...
f(-5) = 5(-5) +40 = -25 +40
f(-5) = 15
Estimate 4704 - 1193 by first rounding each number to the nearest hundred.
Answer:
4700 minus 1200 = 3500
Step-by-step explanation:
round 4704 down to 4700 and 1193 up to 1200
Answer:
4704 - 1193 ≈ 3,500
Step-by-step explanation:
We are given the first step to round each number to the nearest hundred.
=====================================
4,704 can be rounded down since the rounding digit (zero) is less than or equal to 4.
4,704 ≈ 4,700
1,193 can be rounded up since the rounding digit (nine) is greater than more equal to 5.
1,193 ≈ 1,200
=====================================
We will now take the difference of these two numbers:
4700 - 1200 = 3500
=====================================

Answer:
The value of x is 12.
Step-by-step explanation:
As we know that the opposite sides of parallelogram are parallel and congruent. So,
[tex]\twoheadrightarrow{\tt{6x - 6 = 3x + 30}}[/tex]
[tex]\twoheadrightarrow{\tt{6x - 3x = 30 + 6}}[/tex]
[tex]\twoheadrightarrow{\tt{3x = 36}}[/tex]
[tex]\twoheadrightarrow{\tt{x = \dfrac{36}{12}}}[/tex]
