e-lub [12.9K]
<h3>Answer:</h3><h3>The equation for the slope of a line, given two coordinate points, (x1,y1) , (x2,y2), is (y2-y1)/(x2-x1)  </h3><h3>  So we get slope = (1-(-5)) / (4-1)  = 6/3 = 2</h3><h3>A is your correct answer.</h3>

Hope this helps! please consider marking my answer the brainliest :)

Please help for Q4 I’m super lost. Write an expression for the sum of four consecutive odd numbers where 2n+1 is the smallest od
sveta [45]

Answer:

n+2

Step-by-step explanation:

This is a Typical Question on Arithmetic Progression with initial term as 2n+1

The next number in this particular series will be 2n+1+2 which is 2n+3 and so on. Thus a common difference of 2 exists.

The nth term of an Arithmetic Progression AP, bn is represented below where b1 is the first term

bn=b1 +(n-1)d where d is the common difference

For this particular series, the 4th term b4 is

b4= 2n+1+(4-1)2 0r b4 =2n+1+6=2n+7

sum of series is represented by equation: n(b1 +b4)/2 where b1 and b4 are 1st and 4th term respectively

Thus Sum required =4(2n+1+2n+7)/2=4(4n+8)/2=8n+16  0r n+2

What is the value of x?
Alecsey [184]

Answer: x = 8

Step-by-step explanation:

Using The Pythagorean theorem (a^2 + b^2 = c^2) we can find A or In This Case X

Plug In The Numbers:

x^2 + 6^2 = 10^2

simplify

x^2 + 36 = 100

Next, Since Were Trying To Find X And Not C, We Subtract B From C Or 36 From 100

x^2 + 36 - 36 = 100 - 36

simplify

x^2  = 64

Next, To Get Rid Of The Square, Were Going To Find The Square Root Of Both Sides Of The Equation

sqr/a = sqr/64

simplify

x = 8
