Answer:
B: (x + 1) = (y - 2)²
Step-by-step explanation:
0 = y² - x - 4y + 3
We want to find the equation of the parabola in vertex form.
The format for the vertex form is;
y = a(x - h) + k
Where (h, k) is the coordinate of the vertex.
Thus, let's transform 0 = y² - x - 4y + 3 into the vertex form
Let's rearrange to get;
x - 3 = y² - 4y
Let's use method of completing the square to get right hand side;
x - 3 = (y - 2)² - 4
Add 4 to both sides to get;
x - 3 + 4 = (y - 2)²
(x + 1) = (y - 2)²

To find:
The missing values to complete the congruence statements:
1. [tex]\overline{IH}\cong \_\_\_\_[/tex]
3. [tex]\angle KJL\cong \_\_\_\_\_[/tex]
Solution:
1.
We have,
[tex]\Delta HJI\cong \Delta IQP[/tex]
Here, vertices H, J, I are corresponding to I, Q, P. So,
[tex]\overline{IH}\cong \overline{PI}[/tex]
Therefore, the complete statement is [tex]\overline{IH}\cong \overline{PI}[/tex].
3.
We have,
[tex]\Delta JLK\cong \Delta FGH[/tex]
Here, vertices J, L, K are corresponding to F, G, H. So,
[tex]\angle KJL\cong \angle HFG[/tex]
Therefore, the complete statement is [tex]\angle KJL\cong \angle HFG[/tex].
When this 3-digit number is rounded to the nearest hundred, it rounds to 400. The digit in the ones place is the fourth odd number you count beginning with 1. The sum of the digits is 12. What is the number?
Answers
Answer: 417
Step-by-step explanation:
Since the digit in the ones place is the fourth odd number that the person count beginning with 1, then the digit will be 7.
This means the number will be:
____ _____ 7. The number in the units and hundreds place are still unknown. But since the addition of the three numbers gives 12, and approximating to the nearest hundred gives 400. Then the number will be 417.
Check: 4 + 1 + 7 = 12
417 = 400 to nearest hundred

Which equation will solve the following word problem? Vanessa spent $87.00 on entertainment for the week. Her rent costs twelve dollars less than double that amount. How much does Vanessa spend on rent?
2R - $12 = $87
2R = $87 + $12
2 * $87 - $12 = R
2($87) - 2($12) = R
Answers
Answer:
The first answer is correct.
Step-by-step explanation:
Where R represents the amount of rent Vanessa pays, 2r is double that amount, and 2r - 12 would be twelve dollars less than double.
Justin has 58 stickers. If he gives 8 stickers to each of his 7 friends, how many stickers will Justin have left?
Answers
Answer:
2 stickers
Step-by-step explanation:
We multiply his 7 friends by 8 (stickers given to each friend) to get 56 stickers given total.
We subtract 56 from 58 to get 2 stickers remaining for Justin.
Step-by-step explanation:
Justin is giving out 8 stickers to 7 of his friends
To find out how many stickers he passed out, you would need to do 7×8
7×8 = 56
Now you want to subtract 56 from 58 to figure out how many stickers he had left
58 - 56 = 2
Justin is left with 2 stickers

Afla 3 numere naturale știind ca produsul primelor doua este 54, produsul ultimelor doua este 12,iar suma dintre primul și al treilea este 11
Answers
Answer:
Cele 3 numere naturale sunt:
Primul număr = a = 9
Al doilea număr = b = 6
Al treilea număr = c = 2
Step-by-step explanation:
Fie cele 3 numere naturale reprezentate ca:
Primul număr = a
Al doilea număr = b
Al treilea număr = c
Produsul primelor două este de 54
a × b = 54
ab = 54 ...... Ecuația 1
a = 54 / b
Produsul ultimelor două este 12
b × c = 12
bc = 12 ........ Ecuația 2
c = 12 / b
Suma primului și celui de-al treilea este 11
a + c = 11 ...... Ecuația 3
Înlocuim
54 / b pentru a și 12 / b pentru c
54 / b + 12 / b = 11
54 + 12 / b = 11
Cross Multiply
66 / b = 11
11b = 66
b = 66/11
b = 6
Rezolvarea pentru un
a = 54 / b
a = 54/6
a = 9
c = 12 / b
c = 12/6
c = 2
Prin urmare, cele 3 numere naturale sunt:
Primul număr = a = 9
Al doilea număr = b = 6
Al treilea număr = c = 2

I think I know the answer but just wanna be sure?
Answers
Answer:
n = -7
Step-by-step explanation:
49 = -5n - 2n
combine like terms
-5 - 2 = -7
49 = -7n
divide both sides by -7
49/-7 = -7n/-7
49/-7 = n
49/-7 = -7
-7 = n
