Step-by-step explanation:

Find The Minimum Value Of The Parabola Y =X^2 + 5x 3
Answer 2

Answer:

-37/4

Step-by-step explanation:

The minimum value of the parabola y =x² + 5x – 3 is  f(-b/2a)

in this case a = 1 and b = 5 and c = -3

then

-b/2a = -5/2(1) = -5/2

then

f(-b/2a) =  f(-5/2) = -37/4

Ava makes bead bracelets. She has a total of 6,048 beads. each necklace has 24 beads. Her friend Maria says that the greatest number of bracelets she can make with the beads is 162. Explain why Maria's answer is incorrect and how she can find the right answer.

Answers

Each necklace needs 24 beads
Ava has 6,048 beads
To find out how many bracelets she can make we need to see how many time 24 can fit into 6,048 with no remainders
6048 divided by 24 is 252

Maria’s incorrect because to make 162 bracelets you would need 3888 beads because: 162 x 24 = 3888
This is not the greatest amount of bracelets because the are excess beads

A car can be assembled on an assembly line in 6 hours. Assume that the cars are assembled at a constant rate.
. a. How many cars, y, can be assembled in t hours?
b. How many cars can be assembled in a week?

Answers

Answer:

a. \(y = \frac{t}{6}\)

b. y = 28

Step-by-step explanation:

\(y = \frac{t}{6}\)

1 day = 24 hours

1 week = 7 days

In 24 hours:

\(y = \frac{24}{6}\)

y = 4

4 cars/day

In 1 week

\(y =(7)(\frac{24}{6})=7*4\)

y = 28

Answer:

a, b, a

Step-by-step explanation:

Answer:

3. A linear equation must have a constant rate of chang. So, let's start. WE will Have X Represent the money he has in his savings account per month, M will represent how much money he makes each month. And the x values (X) can't have the same two numbers

 X                        M

550                    200

750                    400

950                    600

1150                    800

1350                   1000

1550                   1200

1750                   1400

1950                   1600

2150                   1800

As we can see in the equation above that it takes Peter approximately 9 months to get 2000 in his bank acc.

4. The answer to this question is 37.5 because we do 8*37.5 to get 30,00, and 20,00 + 30,00 = 50,00. So, it takes us 37.5 years to get to 50,00 people.

5. Logan will have 50 because 75*12 - 900. 950 - 900 = 50.

6. So, $50 per month, plus 75*0.10

The answer is 7.5

50 + 7.5 = 57.5 dollars a month you would have to play according to the Verizon plan.

7. 400*15 + 40 will give us our answer to this one.

400*0.15 = 60. 60 + 40 = 100

Now, back to Verizon

400*0.10+50 will give us our answer for this one

400*0.10 = 40. 40 + 50 = 90.

So, if you sent 400 text messages per month then you would prefer Verizon because Verizon would be 90 per month but T-Mobile would be 100 per month

1. First we have to do 1.5*20 because the plant grows 1.5 cm each day for 20 days.

1.5 * 20 = 30.

Now, we do 8*30 because 8 is the current height times the growth of it in 20 days.

8*30 = 240.

So, the plant's height after 20 days is 240 cm.

2. He loses 5 pounds a month. 249 - 5 = 244, 239, 234, 229, 224, 219. So, counting up how many times I subtracted by five, it takes him 6 months to get to 220 pounds.

Hope these help!

Which rational number is one tick mark to the right of Negative StartFraction 6 Over 4 EndFraction on

Answers

Answer:

B>-1 1/4

Step-by-step explanation:

The rational number is one tick mark to the right of -6/4 is \(-1\frac{1}{4}\).

What is number line?

A straight line of numbers is shown visually as a number line. This line is used to compare integers on an endless line that extends on both sides, either horizontally or vertically, at equal intervals. On a horizontal number line, the numbers grow as we walk to the right and decrease as we move to the left.

Given the number -6/4,

if we go right of -6/4 it is moving towards -1

the points right to -6/4 are -5/4, -4/4,....

the next point right of -6/4 is -5/4

the mixed form of -5/4 is  \(-1\frac{1}{4}\).

Hence option B is correct.

Solution

The inequality ...

  7.4p ≤ 74

can be solved by dividing by the coefficient of p:

  p ≤ 10

This means 10 is a solution, but no numbers greater than 10 will be in the solution set.

You have 6 pints of glaze. It takes ⅞ of a pint to glaze a bowl and 9/16 of a pint to glaze a plate

Answers

Your question is Incomplete

Is Your question this?

You have 6 pints of glaze. It takes 7/8 of a pint to glaze a bowl and 9/16 of a pint to glaze a plate.

A. How many bowls could you glaze

B. How many plates can you glaze

C. How much glaze will be left over?

If it is the Answer is below.

(If it not please tell me)

Answer/Step-by-step explanation:

Given:

6 Pints of glaze

takes 7/8 of pint to glaze a bowl

9/16 of a pint to glaze a plate

Part A) How many bowls could you glaze?

You have 6 pints of glaze. It takes 7/8  of a pint to glaze a bowl

so

To find the number of bowls divide 6 by 7/8

= 48/7 = 6.86 bowls

Therefore the answer to part A is equal to 6 bowls.

=================================================================

Part B) How many plates can you glaze?

You have 6 pints of glaze. It takes 9/16  of a pint to glaze a plate

so

To find the number of plates divide 6 by 9/16

=96/2 = 10.67 plates

Therefore the answer to part B is equal to 10 plates.

=================================================================

Part C) How much glaze will be left over?

\(Part A =6-6*\frac{7}{8} =6-\frac{42}{8} =\frac{48}{8} = \frac{42}{8}=\frac{3}{4}\) pint of glazes left

\(Part B=6-10*\frac{9}{16} =6-\frac{45}{8} =\frac{48}{8} -\frac{45}{8} =\frac{3}{8}\) pint of glazes left

Maybe b. Or c but I’m not sure if it’s a problem with the problem with this problem lol it’s still available for sure

This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value

Answers

The value of A/B is given as follows:

A/B = -2.

What are the asymptotes of a function f(x)?

The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:

A/B = 2/-1 = -2.

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.
