A student council sells 44 bouquets for $176. Which equation represents the

vesna_86 [32]

Answer:

$y = 4x$

Step-by-step explanation:

Given

$x = 44$

$y = 176$

Required

Determine the relationship between x and y

First, we calculate the unit rate, using:

$y = kx$

Where k is the unit rate.

Substitute 176 for y and 44 for y

$176 = k * 44$

Divide both sides by 44

$\frac{176}{44} = \frac{44*k}{44}$

$\frac{176}{44} = k$

$4 = k$

$k = 4$

Substitute 4 for k in $y = kx$

$y = 4x$

Hence, the relationship between x and y is: $y = 4x$

Multiply the trinomial x^2+xy+y^2 times the binomial x-y and simplify.

Natalija [7]

Multiply then simplify, that's doing the same work twice...anyway

x^3+x^2y+xy^2-x^2y-xy^2-y^3

x^3-y^3 which if factored is:

(x-y)(x^2+xy+y^2) which is what you started with :)

Yara multiplies and divides a certain number by the same

Butoxors [25]

For this case we have to:

x: Represents the unknown number

y: Represents the exponent of base 10

So, considering a system of equations we have:

$x * 10 ^ y = 40,000\\\frac {x} {10 ^ y} = 0.000004$

From the first equation we have:

$10 ^ y = \frac {40,000} {x}$

Substituting in the second equation:

$\frac {x} {\frac {40,000} {x}} = 0.000004\\\frac {x ^ 2} {40,000} = 0.000004\\x ^ 2 = 40,000 * 0.000004\\x ^ 2 = 0.16\\x = \pm \sqrt {0.16}$

We choose the positive value:

$x = 0.4$

So, the number is 0.4.

So:

$10 ^ y = \frac {40,000} {0.4}\\10 ^ y = 100,000\\y = 5$

Thus, the exponent is 5.

Answer:

Yara use 0.4 and $10 ^ 5$
