Answer:

Step-by-step explanation:

Given:

a varies jointly as b and c.

a=6 when b=2 and a=3.

To find:

The variation constant and the equation of variation.

Solution:

a varies jointly as b and c.

[tex]a\propto bc[/tex]

[tex]a=kbc[/tex]              ...(i)

Where, k is the constant of proportionality.

a=6 when b=2 and a=3.

[tex]6=k(2)(3)[/tex]

[tex]6=6k[/tex]

[tex]\dfrac{6}{6}=k[/tex]

[tex]1=k[/tex]

The value of k is 1.

Putting k=1 in (i), we get

[tex]w=1xy[/tex]

[tex]w=xy[/tex]

Therefore, the variation constant is 1 and the equation of variation is [tex]w=xy[/tex].

Answer:

Step-by-step explanation:

You want to reverse the algebra and solve for y. First you want to subtract the 'a' to both sides.

x - a = -2by^2

Divide by -1 on both sides

-x + a = 2by^2

Divide by 2b on both sides

(-x + a)/2b = y^2

Take the square root of both sides

[tex]\sqrt{(-x+a)/2b}=y[/tex]

Answer:

-56

Step-by-step explanation:

Let the said number be x, so

x / -8 = 7

That's the equation

On solving further, we cross multiply to have

x = -8 * 7

x = -56

That means the number is -56

Answer:

The answer is -2 or C

Step-by-step explanation:

Just input 4 into the equation as x. f(4)=2(4)-10. This gets you 8-10 which is -2. Hope this helps!

Answer:

hey there, person with the same name as me lol. the answer is c. -2

Step-by-step explanation:

in the question they showed that f(x) = 2x - 10

when they ask for the value of any number like f(4)

just replace the variable with this number

for this it will be

2x - 10  = 2 * 4 - 10

which is 8-10

which is equal to -2

you're welcome....

Answer:

0.60 or 0.6

Step-by-step explanation:

To convert you devide the two 6/10 is 0.6

0.6 is a decimal that is equivalent to the fraction 6/10

A number system is defined as a system of writing to express numbers.

A fraction represents a part of a whole.

The given fraction is 6/10.

The fraction is six by ten

In the given fraction is six and denominator is ten.

We need to convert 6/10 to the decimal which is equivalent.

10 is the divisor and 6 is the dividend.

6/10=0.60

Six by ten equal to  zero point six

Hence, 0.6 is a decimal that is equivalent to the fraction 6/10

Answer:

The fraction 4/14 is equal to 2/7 when reduced to lowest terms. To find equivalent fractions, you just need to multiply the numerator and denominator of that reduced fraction (2/7) by the same interger number, ie, multiply by 2, 3, 4, 5, 6

Answer: 1.25m + 3 ≤ 18; Antonio can ride 12 or fewer miles

Step-by-step explanation: so you can break down the answer choices and only have a and b left because no more than means this sign: ≤

and 1.25 is the cost for each mile so your multiplying m and 1.25 and then you add that with 3.

Answer:

The second choice. Because the x-coordinate in the second choice is constant unlike the others, which is a property of a function.
