Find the slope of the line that contains these two points.
(2, -5) and (7, -10)

Answers

$\sf Slope= (y_2-y_1)/(x_2-x_1)$

Where $\sf (x_1,y_1), (x_2,y_2)$ are the two points.

So

$\sf Slope = ( -10-(-5))/(7-2)=(-10+5)/(7-2)=(-5)/(5)=-1$

So the slope of (2,-5) and (7,-10) was $\boxed{ -1}$

m= $(y1-y2)/(x1-x2)$ = $(-5-(-10))/(2-7)$ = $(5)/(-5) =-1$
Answer: slope is -1

Solve the equation by completing the square. Round to the nearest hundredth if necessary. x2 – 3x – 3 = 0

Answers

x² – 3x – 3 = 0

First, add 3 to both sides

x² – 3x – 3 (+3)= 0 (+3)

x² – 3x = 3

Solve for a. 2ax = -3x; a = -3/2

x² - 3x + (-3/2)² = 3 + (-3/2)²

Simplify

x² - 3x + (-3/2)² = 21/4

Complete the square

(3 - 3/2)² = 21/4

solve:

x - 3/2 = √(21/4); x = (√21 + 3)/2

x - 3/2 = -√(21/4); x = ((-√21) + 3)/2

Answers:

x = ((√21) + 3)/2 & x = ((-√21) + 3)/2

chad poured a sidewalk that is 42 ft long. He is going to start at the beginning and make a cut every 20 inches. How many cuts will Chad make?

Answers

So The First Step in tackling this problem is first do $42x12$ , The reason why we do this is because we are converting feet to inches. After that we will get 504 inches. The next and final step is to do 504÷20. Then we will get 25.2 so the final answer is that Chad will make 25 cuts.

Twice because you would divide the 2 numbers together, and you get a small decimal. But since you can't cut a decimal then It would be 2, so 2 cuts. :)

I just need help on confirming my answers please.

If a set has 1,024 subsets, how many elements does it have?

Answers

Answer:

If a set has 1,024 subsets,then it has 10 elements

Step-by-step explanation:

If A is a set containing n elements then total numbers of subsets of A are $2^n$

Here, we are given that

$2^n=1024$

We know that

$1024=2^(10)$

i.e. $2^n=2^(10)$

Hence, n=10

Hence, If a set has 1,024 subsets,then it has 10 elements
