The cost of a ski ticket is x. renting ski equipment costs an additional $10. suzie purchased three tickets and rented 3 sets of equipment. write an algebraic expression to represent suzie's total.

f(x) = 3(x + 10)

Step-by-step explanation:

1.) It may be a bit easier to understand if x had a value, so let's say it equals 20.

2.) f(20) = 3(20 + 10)

3.) f(20) = 3(30)

4.) f(20) = 90

5.) If the ticket cost $20, then the total would be $90. However, any value can be subbed in for x, so answers can vary.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
