Answer:

-1

Step-by-step explanation:

2x² - 5x + 7 is subtracted <em>from </em>x² + 2x - 11, so

(x² + 2x - 11) - (2x² - 5x + 7)

x² + 2x - 11 - 2x² + 5x -7 (Distribute the negative)

-x² + 7x - 18 (Combine like terms)

The leading coefficient is the coefficient of the first term, so it is -1.

777dan777 [17]

Answer:

$83%$ %

Step-by-step explanation:

We have that $2/12=1/6$ of the eggs are cracked, so $1-1/6=5/6$ of the eggs are not cracked.

Recall that $1/6=0.1666666666...$ . This means that $5/6=1-1/6=1-0.166666666...=0.833333333...$ .

Rounding this to the nearest whole percent gives $83%$ %.

Please help me!!!!!! I really neeeeeeed

Butoxors [25]

Answer:

A-(x+4,y-5)

B- move 1 unit left and 7 units down

Step-by-step explanation:

A- 4 units right is x so

(x+4,y__)

5 units down is y so

(x+4,y-5)

B- move 1 unit left and 7 units down

because (x-1,y__) is going left because of the subtraction sign and its the x-coordinate, and (x-1,y-7) is down because its a Y-coordinate and sub so its going down.

<h2><u>TIP- Going left/down is always subtract/negative going right/up is positive/addition.</u></h2>

Write the expression as a single natural logarithm. 3 In b-4 In x?

sergij07 [2.7K]

Option 1: $ln\ \frac{b^3}{x^4}$ is the right answer

Step-by-step explanation:

Given statement is:

$3\ ln\ b - 4\ ln\ x$

First of all we will see about the numbers that are written with the log

The exponent property of log states that

$ln\ (x^y) = y\ ln\ x$

Using the property

$= ln\ b^3 - ln\ x^4$

The division property of log states that:

$ln\ (\frac{x}{y}) = ln\ x - \-ln\ y$

Using this property

$=ln\ \frac{b^3}{x^4}$

Hence,

Option 1: $ln\ \frac{b^3}{x^4}$ is the right answer
