Answer:

Step-by-step explanation:

The equation of a linear function in point-slope form is y – y1 = m(x – x1)

The point is A (x1 , y1)

in this exercice : x1 = 3 and y1 =2

let A(3,2) B(-9,6)

the slope is : m = (YB - YA)/(XB -XA)

(6-2)/(-9-3) =4/(-12) = -1/3

the slope is m = -1/3

The equation is : y – y1 = m(x – x1)

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

or : 3y-6 = -x+3

A Family purchased tickets to the movies in spent a total of $40.75. The family purchase five tickets there was a $.90 processi

muminat

Answer:

$7.25

Step-by-step explanation:

Total amount spent on the ticket = $40.75

Number of ticket purchased = 5

Processing fee per ticket = $0.90

Unknown:

Cost of each ticket = ?

Solution:

To solve this problem, we need to find the processing fee for the 5 tickets purchase;

Processing fee = number ticket x processing fee per ticket

Processing fee = 5 x 0.9 = $4.5

Now, the real cost a ticket = $40.75 - $4.5 = $36.25

So, cost per ticket is;

Cost = $\frac{36.25}{5}$ = $7.25

A 25-foot ladder leans against a house. The bottom of the ladder is 7 feet from the house.

Liono4ka [1.6K]

It makes a 74 degree angle.

The sides of the triangle that are given are the side adjacent to the angle the ladder makes with the ground and the hypotenuse of the triangle.

adjacent/hypotenuse is the ratio for cosine:

cos x = 7/25

To solve this, we will take the inverse cosine:

x = cos⁻¹(7/25) = 73.7 = 74
