Brainlest if Answered What's 5x5?

Answer:

$69

Step-by-step explanation:

Given the amount of money each girl spent based on the number of hours they were shopping modeled by the function p(x) = 3x4 + 2x3 − 4x2 + 21

To get how much they spend together if each go shopping for 2hours, we will substitute x = 2 into the given function as shown:

p(2) = 3(2)⁴ + 2(2)³ − 4(2)² + 21

p(2) = 3(16) + 2(8) − 4(4) + 21

p(2) = 48 + 16 − 16 + 21

p(2) = 48+21

p(2) = 69

Therefore they spend $69 together

Answer: 138$

Step-by-step explanation: 69$ is how much 1 girl spends. They both spend 138%$. Also, I took the test.

Answer:

  (-14, 5.5)

Step-by-step explanation:

Perhaps the easiest way to find the 1/4 point is to find (x, y), then find the midpoint between that and M.

  (x, y) = 2M -(13, 25) = 2(-5, 12) -(13, 25) = (-23, -1)

Then the 1/4 point is ...

  ((-23, -1) +M)/2 = ((-23, -1) +(-5, 12))/2 = (-28, 11)/2 = (-14, 5.5)

_____

If we call the end points A(x, y) and B(13, 25), then we know ...

  M = (A+B)/2

  A = 2M -B . . . . we'll need this in a bit

and the 1/4 point Q is such that ...

  (Q -A)/(B -A) = 1/4

  4Q -4A = B -A . . . . cross multipliy

  Q = (B +3A)/4 = (B +3(2M -B))/4 = (6M -2B)/4 . . . . solve for Q

  Q = (3M -B)/2 . . . . reduce the fractions

  Q = (3(-5, 12) -(13, 25))/2 = (-28, 11)/2 = (-14, 5.5) . . . as above

Answer:

6x^2 + 20x - 96

Step-by-step explanation:

FOIL!!! 3x times 2x is 6x^2,

3x times 12 is 36x,

-8 times 2x is -16x

12 times -8 is -96

36x-16x= 20x

Answer:

Approximately 23 cups of coffee

Step-by-step explanation:

Break even = Fixed cost/Selling price - variable cost

Fixed cost = $75

Selling price = $4.50

Variable cost = $1.25

Break even = $75/$4.50 - $1.25

= 23.076923077

Approximately = 23

Therefore, Mary has to sell approximately 23 cups of coffee daily in order to break evem

Answer:

See Below

Step-by-step explanation:

Ok, so congruent means the same.

Using this knowledge, we can clearly see that the bottom pair are not congruent.

For the first pair, let compare the slopes and lengths of the line segments.

(If you have wax paper, you can trace A and see if it matches B)

GH <=> PQ    = 2 blocks

LG <=> UP    =  5/1 slope

KL <=> TU     = 2 blocks

JK <=> ST      = 1 block

IJ <=> RS        = 1/1 slope

HI <=> QR        =3 blocks

As you can see, all the corresponding side lengths/ slopes are the same.

This means the first pair are congruent.

Answer:

2/3

Step-by-step explanation:

To find the slope use rise over run between two points. You start at one point and count up. Then you go right until you reach your second point. You can also use this formula in the screen shot below. the first point is (x1, y1) the second point is (x2, y2)

Answer:

There are no solutions.

Step-by-step explanation:

−2(4x−2)<−8x+4

Step 1: Simplify both sides of the inequality.

−8x+4<−8x+4

Step 2: Add 8x to both sides.

−8x+4+8x<−8x+4+8x

4<4

Step 3: Subtract 4 from both sides.

4−4<4−4

0<0

Answer:

vertex is 2

Step-by-step explanation:

vertex is 2 because the formula is -b/2(a)

simplify it will be 2

Answer:

The answer is the third number line

Step-by-step explanation:

First let's find the solution to the inequality

4x - 3 is less than 5

    +3                    +3

4x is less than 8

4x/4 is less than 8/4

x is less than 2

Note: If it is less than, it will have an open circle pointing to the left on a number line.

The answer is the third number line

Answer:

option 3

Step-by-step explanation:

4x-3 < 5

1) we first solve the equation and get x < 2

2) we already can eliminate options 1 and 2

3) and we know the answer choices will be less than 2 so the answer is 3 becuase of process of elmination.

Answer:

Step-by-step explanation:

A simple way to calculate the distance between numbers on a number line is to count every number between them. A faster way is to find the distance by taking the absolute value of the difference of those numbers. Absolute value of a number on a number line is its distance from 0 on the number line .

Answer:

7. m<RST = 138°

8. m<MNP = 56°

9. m<WXZ = 130°

10. m<ABC = 118°

Step-by-step explanation:

7. m<RST = 138° (alternate exterior angles are congruent)

8. m<MNP = (a + 28)°

(a + 28)° = 2a° (alternate interior angles are congruent)

a + 28 = 2a

Collect like terms

28 = 2a - a

28 = a

m<MNP = (a + 28)°

Substitute a = 28

m<MNP = (28 + 28)° = 56°

9. m<WXZ = 5y°

5y = (2y + 78)° (alternate interior angles are congruent)

5y = 2y + 78

Collect like terms

5y - 2y = 78

3y = 78

Divide both sides by 3

y = 26

m<WXZ = 5y°

Plug in the value of y

m<WXZ = 5(26)

m<WXZ = 130°

10. m<ABC = (3n - 47)°

(3n - 47)° + (n + 7)° = 180° (same side interior angles are supplementary)

3n - 47 + n + 7 = 180

Collect like terms

4n - 40 = 180

Add 40 to both sides

4n = 180 + 40

4n = 220

Divide both sides by 4

4n/4 = 220/4

n = 55

m<ABC = (3n - 47)°

Plug in the value of n

m<ABC = 3(55) - 47 = 165 - 47

m<ABC = 118°

The part of the pizza that is left = 2 from the 2/3 pizza eaten by Jason.

Word problems in mathematics are the use of arithmetic and mathematical operations to solve problems real-life problems.

From the given information, Let us assume that the total amount of the pizza is 1.

If Jason ate 2/3 of the pizza, then the part of the pizza that is left is:

[tex]\mathbf{=(1 - \dfrac{2}{3})}[/tex]

[tex]\mathbf{=(\dfrac{3 -2}{3 })}[/tex]

[tex]\mathbf{=\dfrac{1}{3 }}[/tex]

Now, we are to split the remaining part of the pizza into 6 parts;

i.e.

[tex]\mathbf{=(\dfrac{\dfrac{1}{3}}{6})}[/tex]

[tex]\mathbf{=(\dfrac{1}{3}}\times \dfrac{6}{1})}[/tex]

= 2
