Welll, the angles should be supplemeentary since they are a linear pair, so the correct answer shoudl be something nlike

2x+x+75=180
3x+75=180
x+25=60
x=35

so the answers are
A. solution B is incorrrect
B. the 2nd to last option (they are a same-side interior angle, which mean that they are supplemtnary... The angle measures should not be set equal to each other)

The correct answers are:

Part A: Solution A is incorrect.

Part B: The labeled angles are same-side interior angles, which are supplementary. The measures of supplementary angles total 180 degrees, so x + 75 plus 2x should be set equal to 180.

Explanation:

The two angles listed are same-side interior angles. This is because they are inside the block of parallel lines and on the same side of the transversal (the side of the trapezoid). Same-side interior angles are supplementary, so these angles must be supplementary. This means their sum is 180°:

2x+x+75 = 180

Calculate limits x>-infinity -2x^5-3x+1

Lera25 [3.4K]

Given:

The limit problem is:

$\lim_{x\to -\infty}(-2x^5-3x+1)$

To find:

The value of the given limit problem.

Solution:

We have,

$\lim_{x\to -\infty}(-2x^5-3x+1)$

In the function $-2x^5-3x+1$ , the degree of the polynomial is 5, which is an odd number and the leading coefficient is -2, which is a negative number.

So, the function approaches to positive infinity as x approaches to negative infinity.

$\lim_{x\to -\infty}(-2x^5-3x+1)=\infty$

Therefore, $\lim_{x\to -\infty}(-2x^5-3x+1)=\infty$ .

Answer: The car travels 97.5 miles in 1.5 hour.

Step-by-step explanation:

Given: A car is traveling down a highway at a constant speed, described by the equation , described by the equation $d=65t$ , where represents the distance, in miles, that the car travels at this speed in t hours.

To find : Number of miles car travel in 1.5 hour.

Simply put t= 1.5 in the given expression , we get

65(1.5)= 97.5

That means , the car travels 97.5 miles in 1.5 hour.
