Answer:

y = 2x
y - 2 = 2(x - 1)

Step-by-step explanation:

(1, 2) & (-2, -4)

Point-Slope Form: y - y1 = m(x - x1) where y represents y2 m represents the slope and x represents x2

In this case, the point slope form will be written as y - 2 = 2(x - 1)

The Slope-Intercept Form will be written as: y = 2x

A slope-intercept equation of the line whose graph is perpendicular to

omeli [17]

Step-by-step explanation:

let eqn be y = mx + b.

2x + 9y = 8

9y = -2x + 8

y = -2/9 x + 8/9

since the lines are perpendicular, product of the slope of the two lines = -1.

hence,

m x -2/9 = -1

m = 9/2

sub (0, -3):

-3 = 9/2(0) + b

b = -3

therefore equation is: y = 9/2x - 3

Answer:

40.80 km

Step-by-step explanation:

Given: AP (opposite)= 33 km

PB(adjacent)= 24 km

Now, finding the value of AB (hypotenous)

Using the pythagorean theoram to solve it.

$AB^{2} = AP^{2} + PB^{2}$

⇒ $AB^{2} = 33^{2} + 24^{2}$

⇒ $AB^{2} = 1089+576$

⇒ $AB^{2} = 1665$

Taking square root on both side, remember; $\sqrt{x^{2} } = x$

⇒ $AB= \sqrt{1665}$

∴ AB= 40.80 km

Bill makes leather shoes. He charges $45 for a pair of women's shoes and $50 for a pair of men's shoes. He sells x pairs of wome

olga_2 [115]

$45x +$50y =$2,500
Since you want to know how many men's shoes he must sell to make $2500 , plug 0 in for x pairs of women's shoes.
$45(0) + $50y =$2,500
0 + $50y =$2,500
$50y = $2,500
$50y/50= $2,500/$50
y = 50

He must sell 50 pairs of men's shoes to still earn his weekly income of $2,500

Check

$45(0) + $50(50) = $2,500
$0 + $2500= $2,500
$2500 = $2500

Use the graph to determine the solution of the inequality |x + 1| + 2 > 5.

Aleks [24]

Use the graph to determine the solution of the inequality |x + 1| + 2 > 5.

To graph this , first we make the absolute function alone

|x + 1| + 2 > 5

to make absolute function alone we subtract 2 from both sides

|x + 1| > 3

x+1 inside the absolute function . so x=-1

From -1, move 3 units to the right and 3 units to the left.

For x>2 , shade the graph to the right

For x< -4, shade the graph to the left

The graph is attached below

The solution to the inequality is x<-4 and x>2
