Pleaseee I really need help I only got 45

Answer:

(1,-9)

Step-by-step explanation:

Answer:

vertex = (1, - 9 )

Step-by-step explanation:

The vertex is located on the axis of symmetry

The axis of symmetry is at the midpoint of the zeros

Find the zeros by letting y = 0, that is

(x - 4)(x + 2) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 4 = 0 ⇒ x = 4

Then equation of axis of symmetry/ x- coordinate of vertex is

x = [tex]\frac{-2+4}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1

Substitute x = 1 into the equation for corresponding value of y

y = (1 - 4)(1 + 2) = (- 3)(3) = - 9

vertex = (1. - 9 )

If you were to multiply the percentages by the numberws your using to the AB formula you can get the answer 252 B

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

A number line is a horizontal line with negative values on the left-hand side of an arbitrary number 0 and positive values on the right-hand side of 0.

The location of point A on a number line = -24

The location of point C on a number line = 36

The distance between -24 and 36 can be simply calculated by counting the number of units between.

Starting from -24, we would need to move 24 units on the right side to reach the 0 and 36 units right to reach 36.

So, the total units will be: 24+36 = 60

A second simple method to calculate the distance between point A and point C is:

Distance between A and C = location of C - location of A

                                              = 36 - (-24)

                                              = 36+24

                                              = 60 units

Thus, the distance between A and C is 60 units.

Now, point B is located halfway between point A and point C.

Thus,

i.e.

The location of point B = The location of point C - 30

                                       = 36 - 30

                                       = 6

Thus, point B is located at 6.

Verification:

The location of point B = The location of point A + 30

                                       = -24 + 30

                                       = 6

Thus, point B is located at 6.

Thus, it is verified that point B, halfway between point A and point C.

Hence,

'6' is the value of point B halfway between point A and point C.

Answer:

  (a)  -2

Step-by-step explanation:

Put -1 where x is and do the arithmetic.

  f(x) = x³ +2x² -3

  f(-1) = (-1)³ +2(-1)² -3

  f(-1) = -1 +2 -3 = 1 -3

  f(-1) = -2

answer

15.5%

Step-by-step explanation:

length = 30

30+10%=33

breadth=20

20+5%=21

area of rectangle = length × breadth

600² centimeters = 30 × 20

693² centimeters = 33 × 21

Increase = 15.5%

Answer:

Step-by-step explanation:

y = 25x +100

y- is the total money spent on the phone

x-is the number of months you had service

the relationship between x and y is proportional ( if x grows, y grows)

For example: after 2 months you would had payed $100 for the phone + the $25 each of the 2 months. y= 25*2 +100 = $150

Answer:

the answer to this question is 66

Answer:

Jo earned a profit of $2500.

Step-by-step explanation:

Given that:

Selling price of 5000 gallons = $1 per gallon

Total selling price = 1 * 5000 = $5000

Production cost = 50 cents per gallon = $0.5 per gallon

Total production cost = 0.5 * 5000 = $2500

Production cost < Selling cost

Therefore,

Jo earned profit on gasoline.

Profit = Selling cost - Production cost

Profit = 5000 - 2500

Profit = $2500

Hence,

Jo earned a profit of $2500.

Step-by-step explanation:

Answer: The birthday boy got [tex]\dfrac13[/tex] of cake and rest each of the 4 children got [tex]\dfrac16[/tex] of cake.

Step-by-step explanation:

1 cake is divided into 6 pieces.

1 piece = [tex]\dfrac16[/tex]

Birthday boy got 2 pieces.

Part of cake he has = [tex]2\times\dfrac16=\dfrac26=\dfrac13[/tex]   [divide numerator and denominator by 2]

So, birthday boy got [tex]\dfrac13[/tex] of cake and rest each of the 4 children got [tex]\dfrac16[/tex] of cake.

Answer:

  a) 3, 8, 63, 3968

  b) some other kind

  c) continue to evaluate terms sequentially

Step-by-step explanation:

a) To find the first four terms, use the recurrence relation:

  t(1) = 3 . . . given

  t(2) = t(1)^2 - 1 = 3^2 -1 = 9 -1 = 8

  t(3) = 8^2 -1 = 64 -1 = 63

  t(4) = 63^2 -1 = 3969 -1 = 3968

The first 4 terms are 3, 8, 63, 3968.

__

b) The terms have no common difference or ratio, so the sequence is some other kind of sequence. The ratios of terms form a sequence that is approximately exponential.

__

c) Colin can find the 10th term by evaluating successive terms using the recursion relation. (It is approximately 2.0351×10^230.)

Answer:

...

Step-by-step explanation:

Answer: The answers are:

6 + 2 = 8

4 + (-1) = 3

Step-by-step explanation:

Add 6 by 2.

Solve for X.

4 + X = 3

To find X, we use the integer rule. We can use this:

Positive and Positive =  Positive

Negative and Negative = Negative

Positive and Negative = Both (It depends if the negative or positive is larger than the other)

For this problem, we can use: Positive and Negative = Both.

If we look at the chart, we can see 4 and 3. How can we get 4 + ? = 3? We can use the integer, -1. Since we said, Positive and Negative = Both, we must compare the positive-addend (4) by the negative-addend (-1).

4 is greater than -1

4 > -1

Therefore, X equals -1.

4 + (-1) = 3

Answer: 8, -1

Step-by-step explanation:

The table shows some addition problems.  Each column is its own problem, with the first two rows being addends and the bottom row being the sum.  Thus, simply do 6+2 to get the first blank(left-to-right), 8.  Then, do 4+x=3 to get the second blank, or -1.
