The subtraction of the polynomial (19xy + 3y - 28) - (- 15xy - 2y - 15) is 34xy + 5y - 13

<h3>How to subtract polynomial</h3>

Given:

(19xy + 3y - 28) - (- 15xy - 2y - 15)

Open the parenthesis

= 19xy + 3y - 28 + 15xy + 2y + 15

collect like terms

= 19xy + 15xy + 3y + 2y - 28 + 15

= 34xy + 5y - 13

Match the y-coordinate with the given x-coordinate for the equation y = log2x.

Troyanec [42]

Logs are exponents so the log base 2 of 2 raised to the power n is just n.

$y = \log_2 x$

1. $\log_2 8 = \log_2 2^3 = 3 \quad$ nope, not -1

2. $\log_2 4 = \log_2 2^2 = 2 \quad$ nope, not 1

3. $\log_2 2 = 1 \quad$ nope, not 3

4. $\log_2 1 = \log_2 2^0 = 0 \quad$ YES, matches, CHOOSE ME!

5. $\log_2 \frac 1 2 = \log_2 2^{-1} = -1 \quad$ nope, not 2

Answer: choice 4

Find the missing number in this proportion.<br><br> 7 2<br> = <br> 4

borishaifa [10]

Answer:

x = 14

Step-by-step explanation:

I don't know which one you are supposed to solve it by so I will do both.

Solution by Cross Multiplication

For the equation

7x=24

The cross product is

7×4=x×2

Solving for x

x=7×42

and reducing

x=14

Solution by Proportion

Since the equation is an equality

7 ÷ 2 = 3.5

Then it is true that

x ÷ 4 = 3.5

Solving for x

x = 4 × 3.5

x = 14

Help with properties of rhombus,rectangles and squares

ladessa [460]

Answer:

<1 : 36 degrees

<2 : 90 degrees

<3 : 36 degrees

<4 : 54 degrees

Step-by-step explanation:

First off, rhombus's have right angles formed at the middle, meaning that <2 is 90 degrees. Then, it's given that angle is 54 degrees, and its alternate interior angle is the one that is adjacent to <3. To find <1, add 90 and 54, and subtract that from 180. So <1 is 36 degrees. So that automatically makes < 3, 36 degrees and < 4, 54 degrees.
