Answer:
(- 1, 0) and (9, 0 )
Step-by-step explanation:
To find the x- intercepts let y = 0 in the equation and solve for x, that is
x² + y² - 8x - 8y - 9 = 0
x² - 8x - 9 = 0 ← in standard form
(x - 9)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 9 =0 ⇒ x = 9
x + 1 = 0 ⇒ x = - 1
x- intercepts are (- 1, 0 ) and (9, 0 )
Answer:
01 2002
Step-by-step explanation:
Set up a proportion
2/3= 120/x
2*60=120
3*60=180
x=180
Final answer: $180
We can have different variables to represent each brother (there can be different variations and ways to solve, but I'll do it my way).
Matt=m
Jeff=3m
Todd=m+25
Matt Jeff Todd
m+3m+(m+25)=275 3(50) 50+25
5m+25=275 =150 =75
5m=250
m=50
Matt spent $50, Jeff spent $150 and Todd spent $75
Check:
50+150+75
=$225
Okay so what you want to do is find the mcd or most common denomanater
to do that you want to list out the factors of 3 and 6. after you do that you should see the the mcd is 6. so now 6 is your new denamanater. so you keep 5/6 and for 2/3 you multiply the top and bottum by 2 so your new fraction is 4/6
so there isnt a correct answer to thing question
