<h2>Answer:</h2><h3>f(4) = 122</h3>

________________________________________________

<h3>Calculate</h3>

$Substitute\ x=4\ into\\ f(x)=7x^2+4x-6$

_________________________________________________

<h3>Substitute</h3>

$f(4)=7\times 4^2+4\times 4-6$

___________________________________________________

<h3>Calculate the power</h3>

$f(4)=7\times 16+4\times 4-6$

___________________________________________________

<h3>Calculate the product or quotient</h3>

$f(4)=112+4\times 4-6\\ f(4)=112+16-6$

___________________________________________________

<h3>Calculate the sum or difference</h3>

$f(4)=128-6\\ f(4)=122$

1. The Cajun Heartland State Fair charges $1.25 per ticket for the rides. Johnny bought 25 tickets for the rides and spent a tot

vekshin1

Let number of ride tickets = x tickets and

Total cost of fair admission and ride = $y.

Given cost of each ticket = $1.25 and

Number of tickets = 25 tickets.

Total Cost of 25 ticket = Number of tickets * cost of each ticket = 25 * 1.25 = $31.25.

Total money spent = $43.75.

Total money spent = Fair admission + Total Cost of 25 ticket

43.75 = Fair addmission + 31.35.

Subtracting 31.25 from both sides, we get

43.75-31.35 = y - 31.35 - 31.35.

12.50 = Fair addmission charge

Therefore, Fair addmission charge = $12.50.

We know slope, intercept form

y = mx+b.

Where, is m the slope (cost of each ticket) and b is the y-intercept( Fair addmission charge)

Plugging values in slope-intercept form, we get

y = 1.25 x+ 12.50.

a) We took x for number of tickets for the rides, and y for total cost of ride tickets and fair admission.

b) We got equation y = 1.25 x+ 12.50.

c) For the equation y = 1.25 x+ 12.50, fix charge for fair admission is $12.50 and cost of each ride ticket is $1.25. Total cost (y) of ride tickets and fair admission will be 1.25 times x number of tickets + $12.50 fair admission charges.
