Answers

Answer 1

Answer:

Answer:

X = - 6

Step-by-step explanation:

x + 2 = 1/2x - 1

$2 + 1 = (1)/(2)x - x$

$3 = - (1)/(2)x$

$x = ( - 3)/( (1)/(2) ) \n x = ( - 6)/(1) \n x = - 6$

Hopethishelps:)

2x^3-8x^2-24x=2x(ax+b)(cx+d)

a=1 and d=-6

Answers

Answer:

b = 2, c = 1

Step-by-step explanation:

2x³ - 8x² - 24x == 2x(ax + b)(cx + d)

2x³ - 8x² - 24x = 2x(x² - 4x - 12)

= 2x(x + 2)(x - 6)

it is 10 3\5 miles from Alston to Barton and 12 1/2 from Barton to Chester.the distance from Alston to Durban,via BARTON and Chester,is 35 miles.how far is it from Chester to Durban.

Answers

Answer:

Distance from Chester to Dublin is $11(9)/(10)$ miles

Step-by-step explanation:

Given :

Distance from Alston to Barton (A to B)= $10(3)/(5)=(53)/(5)$ miles

Distance from Barton to Chester (B to C)= $12(1)/(2)=(25)/(2)$ miles

Distance from Alston to Dublin via Barton and Chester(A to D) = 35 miles

Let the distance from Chester to Durban(C to D) = x

Refer the attached figure.

Therefore,

Total distance(A to D)= distance (A to B)+distance (B to C)+distance (C to D)

Putting values , we get

$35=(53)/(5)+(25)/(2)+x$

$35-(53)/(5)-(25)/(2)=x$

$35-10.6-12.5=x$

$11.9=x$

or $x=11(9)/(10)$

Distance from Chester to Dublin is $11(9)/(10)$ miles.

Final answer:

To find the distance from Chester to Durban, add the distances from Alston to Barton and Barton to Chester, and subtract this total from the given distance from Alston to Durban.

Explanation:

To find the distance from Chester to Durban, we need to determine the distance from Alston to Durban. We can start by finding the distance from Alston to Chester by adding the distances from Alston to Barton and from Barton to Chester. The total distance is 10 3/5 miles + 12 1/2 miles = 23 1/10 miles. Now, to find the distance from Alston to Durban, we subtract this total distance from the given distance from Alston to Durban via Barton and Chester: 35 miles - 23 1/10 miles = 11 9/10 miles. Therefore, it is 11 9/10 miles from Chester to Durban.

Take two points to find the slope
Let;s take (1, -3) and (-3, -1)

Point slope formula is

m = $(y2-y1)/(x2-x1)$
or
y₂-y₁ = m×(x₂-x₁) Which is the same thing

m = $(-1-(-3))/(-3-1)$
= $(2)/(-4)$
It can be simplified:
= $-(1)/(2)$
Now we found the slope

Same formula:
y₂-y₁ = m × (x₂-x₁)
Substitute the point only (1, -3)
y₂-(-3) = $-(1)/(2)$ × (x₂-1)
y₂ + 3 = $-(1)/(2)$ × (x₂ - 1) (minus minus = plus)
