Jessica has a $5 off coupon towards her next purchase of short sleeved t-shirts at her favorite store in the mall. t-shirts are on special this week only for $8 each. the equation y = 8x - 5 will give jessica her final cost (y) to purchase x number of t-shirts. if x = 9, what is the ordered pair (x, y)? [ignore sales tax.] 1. (9, 5) 2. (17, 9) 3. (8, 9) 4. (9, 67)

i use my brain for prombles like this maybe you could try it

step-by-step explanation:

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.

plzz mark brainlest last one got deleted. cause i didn't explain it but i did but i understand what the mod meant

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

60: 45 =12: 9 =4: 3 so the answer is 4: 3
