Brian wants to purchase a car wash "package" from his local car wash. he can either get unlimited car washes for a month for $35 with no additional charges. or, he can buy a discount package, where he pays $22 for the month plus $1.50 per car wash. he wants to know how many car washes he would need to get in order to make the $35 deal a better choice.

y=22x+1.5 substitute 35 for x: y=22(35)+1.5; y=771.5, which means it would take 772
car washes for the plans to be worth the same amount.

y=1.5x+22 substitute 35 for y: 35=1.5x+22; y≈8.7, which means at 9 car washes, the unlimited package at $35
would be cheaper.

y=22x+1.5 substitute 35 for y: 35=22x+1.5; y≈1.5, which means at 2 car washes, the unlimited package at $35
would be cheaper.

y=1.5x+22 substitute 35 for x: y=1.5(35)+22; x=74.5, which means the discount package is cheaper unless brian gets 75 car washes.

y=1.5x+22 Substitute 35 for x: y=1.5(35)+22; x=74.5, which means the discount package is cheaper unless Brian gets 75 car washes. or d plz make Brainleist.

Step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
