The following are weekly production in unit of 60 workers in a

The variables x and y vary inversely. Use the given values to write an equation relating x and y. Then find y when x=−3.

-BARSIC- [3]

Answer:

xy-3x=40, x=5

x(y-3)=40

y-3=(40/x)

y=(40/x)+3

y=(40/5)+3

y=8+3

y=11

How many solutions does the system have ? 20x - 5y = 5 4x - y = 1

Aleks04 [339]

Answer:

Infinite solutions.

Step-by-step explanation:

Just plug your equation into desmos graphing calculator and it will graph it for you. If it is infinite the two lines will lay on top of one another. If there is only one solution it will be where the two lines intersect. If there are no solutions the two lines will be parallel.

I need help with this....

trapecia [35]

Answer:

-512

Step-by-step explanation:

The laws of exponents state that multiplying two exponents together of the same base allows you to add the exponents. Raising an exponent to another power allows you to multiply the exponents. In this case. you have $(-2)^3*((-2^3))^2$ . First, you take the second term, or $((-2^3))^2$ and simplify it. Since you're raising an exponent to another exponent you have $(-2)^(3*2)$ , or $(-2)^6$ . Now, you multiply by $(-2)^3$ . Since they both have the same base, you can add the exponents to get $(-2)^9$ . Since $(-2)^9$ is raised to an odd exponent, you know you're answer is going to be negative. $2^9$ is 512, so that negative would be -512. If you're looking for an expression for this, you can write $(-2)^9$

six ants simultaneously stand on the six vertices of a regular octahedron, with each ant at a different vertex. simultaneously a

Thepotemich [5.8K]

The probability that no two ants will reach the same vertex is 5/256.

Plane, point B and attention. Ants that move to D can come from either E or C. Ants moving to E can come from either B or D of points A and F of the octahedron. Therefore, there are 2 degrees of freedom to decide which ants move to D, 2 degrees of freedom to decide which ants move to E, and 2 degrees of freedom to decide which ants move to A.

So there are 2× 2× 2=8 ways an ant can move to different points.

There are 8 ways for ants to move to different points.

Points B, there are a total of 8 + 4 + 8 = 16 ways Ant can move to her different points. Aligned the square so that point B is defined as point where the ant moved from point A.

An ant can actually move from point A to 4 different points, so there are a total of 4×20=80 ways an ant can move to different points.

Each ant acts independently and has 4 different points to choose from.

So each ant has a 1/4 chance of moving to the desired location. Since he has 6 ants, the probability of appearance is

= 1/4096

So, the desired answer is 80/4096

= 5/256

Write the equation of the parabola in standard form

Igoryamba

At those two x-intercepts, I know that x=2 and x=-2.
to get this, I know that there are two factors set to 0.
x+2=0 and x-2=0
so, if you multiply (x+2)(x-2)=y
then you will have standard form
x^2+2x-2x-4=y
y=x^2-4
