X and y vary inversely and x=50 when y=5 find y when x=10 what is k?
Kisachek [45]

Answer:

Part A)

1)  k=250

2) y=25

Part B)

1)  k=7

2) y=84

Step-by-step explanation:

Part 1) x and y vary inversely and x=50 when y=5 find y when x=10 what is k?

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form y*x=k or y=k/x

step 1

<u>Find the value of k</u>

x=50 when y=5

substitute the values

y*x=k ------> 5*50=k -----> k=250

The equation is equal to

y*x=250  or y=250/x

step 2

<u>Find y when x=10</u>

substitute the value of x in the equation and solve for y

y*(10)=250

y=250/10=25

Part B) x and y vary directly and x=6 when y=42 find k what is y when x=12

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form y/x=k or y=kx

step 1

<u>Find the value of k</u>

x=6 when y=42

substitute the values

y/x=k ------> 42/6=k -----> k=7

The equation is equal to

y/x=7  or  y=7x

step 2

<u>Find y when x=12</u>

substitute the value of x in the equation and solve for y

y=7(12)=84

I don’t get the second question.
tatyana61 [14]

it should be 3+(-7)  because look at the number closest to the number line, which is positive 3 then the number next to it is negative 7 because it is heading downward towards the opposing side.

6 + (9 − 1) 2 ÷ 4 ⋅ 1 over 2 whole to the power of 4
Bas_tet [7]

Answer:

625

Step-by-step explanation:

1. parenthesis first, so it simplifies to ((6+(8)2÷4*1)/2)^4

2. pemdas says that multiplication and division go before addition and subtraction, so ((6+(8)2÷4*1)/2)^4 becomes ((6+16÷4*1)/2)^4 ---> ((6+4)/2)^4

3. then simplify inside of the parenthesis, so it becomes 5^4, which is 625
