Answer:
honestly they all are the same i had a similar question and thats what i put so yeah sorry if i didn`t help
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h. k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (- 6, - 1), thus
y = a(x + 6)² - 1
To find a substitute one of the roots into the equation
Using (- 3, 0), then
0 = a(- 3 +6)² - 1
0 = 9a - 1 ( add 1 to both sides )
1 = 9a ( divide both sides by 9 )
a = 
, thus
y = (x + 6)² - 1 ← in vertex form
Expand factor and simplify
y = (x² + 12x + 36) - 1 ← distribute
y = x² + 
x + 4 - 1
= x² + x + 3 ← in standard form
Answer: 8.50
Step-by-step explanation: I like to turn fractions into deciamls.
5/6 = .83 (I get 0.83 by 5 divided by 6)
2/3 = .66 (I also got 0.66 by 2 divided by 3)
.8333 + .66 = 149 = 1.49333
5 + 2 = 7 + 1.49 = 8.49
Now round up 8.49333 and you'll get 8.50 or 8 ¹/²
Let me know if I'm wrong, have a good day!
Answer:
8
Step-by-step explanation:
4 ÷ 
= 
· 
4 · 2 = 8
Here are the steps
put it into y=mx+b 4y=-5x+20
to isolate y divide both sides by y=-5/4+5
to find the xi
xi is when y=0 so plug it in to the equation 4y=-5x+20 4(0)=-5x+20
0=-5x+20 subtract 20 from each side -20=-5x the negatives cancel out 20=5x
to isolate x divide each side by 5 x=20/5
20/5=4
Answers:
m=-5/4
yi=5
xi=4
