Answer:

Step-by-step explanation:

50% is $\frac{50}{100}$ but we're working with 64 units, not 100. So, we must find a number that represents 50 but in 64 units.

$\frac{50}{100}=\frac{x}{64}$

If you solve for x, you get:

$x=\frac{50*64}{100}\\ x=32$

$\frac{50}{100}=\frac{32}{64}$

Write the polynomials in standard form:<br><br> (15–7xy^2)–(y^3–y^2x–15)

stepan [7]

<h3>Answer:</h3>

-y³ -6y²x +30

<h3>Step-by-step explanation:</h3>

When parentheses are eliminated and the y variable placed first in each term, the expression simplifies to ...

... 15 -7y²x -y³ +y²x +15

Arranging like terms together, we have ...

... -y³ +y²x(-7 +1) +(15 +15)

... -y³ -6y²x +30

_____

The two different 3rd-degree terms can be expressed in either order. I have chosen to list the term with the largest exponent first. The expression could also be written with the same-degree terms in "lexicographical order", meaning the expression would be written ...

... -6xy² -y³ +30

Which equations represent the line that is parallel to 3x − 4y = 7 and passes through the point (−4, −2)? Select two options. y

andriy [413]

Answer:

Step-by-step explanation:

We want a line parallel to 3x − 4y = 7. Any such line will have an equation of the same form but a different constant.

If the new line is to pass through the point (-4, -2), replace x with -4 and y with -2. We obtain:

3(-4) − 4(-2) = -12 + 8 = -4. Thus, the desired new equation is 3x − 4y = -4.

This could also be written as 3x − 4y + 4 = 0. We could also solve this for y, obtaining:

3x + 4 = 4y, or y = (3/4)x + 1.
