x isnt a number

Answer:

x is less than and always 24

Answer:

-4.5

Step-by-step explanation:

-6, -5.5, -5, -4.5 (x), -4  

Step-by-step explanation:

Hi,

f(x) = (x - 1) - 3

The -1 is the 1 unit to the right (even though it's being subtracted, it's going to the right because it's embedded with the x)

And the -3 is not embedded with the x, meaning the function will move 3 units down.

I hope this helps :)

Answer:

$2.21

Step-by-step explanation:

Given data

Cost = $13.00

Tip= 17%

Let us find the amount of the tip

=17/100*13

=0.17*13

=$2.21

Hence the tip is $2.21

Answer:

The bakery will bake 600 butterscotch bread, 550 chocolate bread, and 1,000 coconut bread

Step-by-step explanation:

In order to answer the word problem question, we list the parameters as follows;

The number of bread types the bakery takes = 3 types of bread

The monthly cost of the bakery for baking the bread, C = RM 6,850

The number of bread loaves baked = 2,150

The cost of baking a loaf of butterscotch bread = Rm 2

The cost of baking a loaf of chocolate bread = Rm 3

The cost of baking a loaf of coconut bread = Rm 4

The sale price of a butterscotch bread = Rm 3

The sale price of a chocolate bread = Rm 4.50

The sale price of a coconut bread = Rm 5

The amount of monthly profit the bakery makes, P = Rm 2,975

Therefore, the total revenue of the company, R = C + P

∴ R = Rm 6,850 + Rm 2,975 = Rm 9,825

Let 'x', 'y', and 'z', represent the number of loaves of butterscotch, chocolate, and coconut bread the company bakes respectively

Then we get;

x + y + z = 2,150...(1)

2·x + 3·y + 4·z = 6,850...(2)

3·x + 4.5·y + 5·z = 9,825...(3)

Multiplying equation (1) by 2 and subtracting from equation (2) gives;

2·x + 3·y + 4·z - 2×(x + y + z) = 6,850 - 2 × 2,150 = 2,550

2·x - 2·x + 3·y - 2·y + 4·z - 2·z = 2,550

∴ y + 2·z = 2,550...(4)

Adding equation (1) to (2) and subtracting from (3) gives;

3·x - 3·x + 4.5·y - 4·y + 5·z - 5·z = 9,825 - (6,850 + 2,150) = 825

1.5·y = 825

y = 825/1.5 = 550

The number of loaves of chocolate bread baked, y = 550

From equation (4), we get;

550 + 2·z = 2,550

2·z = 2,550 - 550 = 2,000

z = 2,000/2 = 1,000

The number of loaves of coconut bread baked, z = 1,000

∴ From equation (1) x = 2,150 - (550 + 1,000) = 600

The number of loaves of butterscotch bread baked, x = 600.

Answer: I’m not sure if I’m correct but I’m pretty sure it’s C

Given:

The graph of a quadratic function opens downward and has its vertex at (0, 1).

To find:

The quadratic function.

Solution:

The vertex form of a quadratic function is:

[tex]y=a(x-h)^2+k[/tex]          ...(i)

Where, a is a constant and (h,k) is the vertex.

If a<0, then graph opens downward and if a>0, then graph opens upward.

It is given that the quadratic function opens downward and has its vertex at (0, 1). It means a must be negative.

Putting h=0 and k=1 in (i), we get

[tex]y=a(x-0)^2+1[/tex]

[tex]y=ax^2+1[/tex]

For [tex]a=-1[/tex],

[tex]y=(-1)x^2+1[/tex]

[tex]y=x^2+1[/tex]

So, option A is correct.

In other options the leading coefficient is positive it means their graphs open upward. So, options B, C and D are incorrect.

Therefore, the correct option is A.

The measure of angle ABC by the given data is 57 degrees.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

∠ABD=70∘

Now,

To find the measure of angle ABC, we need to use the fact that the sum of the angles in a triangle is 180 degrees. We can write an equation using this fact and the given information:

m∠ABD + m∠CBD + m∠ABC = 180 70 + (5x + 13) + (3x + 33) = 180

To solve for x, we need to simplify and isolate it by performing the inverse operations on both sides. We can do this by following these steps:

Step 1: Combine like terms on both sides of the equation.

70 + 5x + 13 + 3x + 33 = 180 8x + 116 = 180

Step 2: Subtract 116 from both sides of the equation.

8x + 116 - 116 = 180 - 116 8x = 64

Step 3: Divide both sides by 8 to get x by itself.

8x / 8 = 64 / 8 x = 8

Now that we have the value of x, we can plug it into the expression for m∠ABC and simplify:

m∠ABC = 3x + 33 m∠ABC

= 3(8) + 33 m∠ABC

= 24 + 33 m∠ABC = 57

Therefore, by algebra the answer will be 57 degrees.

--------------

19x +10

Answer:

7x+1

Step-by-step explanation:

1/2 (8x+6) + (3x-2)

distribute the 1/2 into (8x+6)   --- ( just means to divide by 2)

4x+3 + (3x-2)

then put common terms together

4x + 3x = 7x

+3 -2 = 1

= 7x + 1

Step-by-step explanation:

3x + y = 11 ...(1)

2x - y = 4 ...(2)

From equation (1) we get,

3x + y = 11

x = 11 - y/3

Now, put the value of x = 11 - y/3 in equation (2) we get,

2x - y = 4

2(11 - y/3) - y = 4

22 - 2y/3 - y = 4

22 - 2y - 3y = 12

22 - 5y = 12

5y = 22- 12

5y = 10

y = 10/5

y = 2

Now, Put the value of y = 2 in equation (1)

3x + y = 11

3x + 2 = 11

3x = 11 - 2

3x = 9

x = 9/3

x = 3

Thus, The value of x is 3 and y is 2

3x + y = 11

3(3) + 2 = 11

9 + 2 = 11

11 = 11

2x - y = 4

2(3) - 2 = 4

6 - 2 = 4

4 = 4

Hence, L.H.S = R.H.S

Answer:

−x²−8x+8

Step-by-step explanation:

Answer: A. 74+28(7)=$382

B. 28 hours.

Step-by-step explanation: or b, what you need to do is minus 74 from 382. Then divided by 28.

Answer:

11 hours

Step-by-step explanation:

h = hours

382 = 74 + 28h

subtract 74 from both sides

308 = 28h

h = 11

Check:

382 = 74 +28(11)

382 = 308 + 74

382 = 382

10=-2x+20

Step-by-step explanation:

Above line is incorrect. It should be 10=10x+20 . You add +6x to get 10x, not -6x.

then solve

10=10x + 20

-10=10x

-1=x

if you substitute -1 for x in the original problem, it equals:

-2(3(-1)-5)=4(-1+3)+8

-2(-8)=4(2)+8

16=8+8

Answer:

EG is parallel to FH and AD is the transversal.

We know that the interior angles on the same side of the transversal are supplementary.

Angle EBC and Angle FCB are interior angles on the same side of the transversal.

So, Angle EBC + Angle FCB = 180°

=> Angle EBC + 76° = 180°

=> Angle EBC = 180° - 76°

=> Angle EBC = 104°.

Answer — 104°

Answer:

C is a right triangle

Step-by-step explanation:

To determine if the triangle is right use Pythagoras' identity

A

9.4² = 88.36

6.4² + 7.1² = 91.37

88.36 ≠ 91.37 , thus not a right triangle

B

8.4² = 70.56

5.2² + 6.3² = 66.73

70.56 ≠ 66.73 , thus not a right triangle

C

9.7² = 94.09

6.5² + 7.2² = 94.09

Thus C is a right triangle

D

8.4² = 70.56

5.1² + 7.3² = 79.3

70.56 ≠ 79.3 , thus not a right triangle

Answer:

Answer C is the correct one

Step-by-step explanation:

Remember that the Pythagorean Theorem applies only to right triangles.  In Answer A, the legs of the triangle shown are 6.4 and 7.1; we apply the Pythagorean Theorem and check whether the length of the hypotenuse is indeed 9.4:

6.4² + 7.1² = 40.96 + 50.41 = 91.37.  

Is √91.37 equal to 9.4?  Not quite!  For now, reject Answer A.

Answer B:  5.2² + 6.3² yields 66.73.  Is this equal to 8.4²?  No, it is not.

Reject Answer B.

Answer C:  7.2² + 6.5² = 94.09.  Is this equal to 9.7²?  YES.  So Answer C is the correct one.

Solution :

Cost of carpeting per square yard = $ 15.00

For 3 ft by 6 ft

1 yard = 3 feet

∴ 1 feet =  [tex]$\frac{1}{3}$[/tex] yard

So,

Therefore, area of 3 ft by 6 ft is = [tex]$3 \times \frac{1}{3} \times 6 \times \frac{1}{3} $[/tex]

                                                    = 1 x 2

                                                    = 2 square yard

Therefore, cost of carpeting 2 square yard = 2 x 15

                                                                       = $ 30

For 9 ft by 12 ft

1 yard = 3 feet

∴ 1 feet =  [tex]$\frac{1}{3}$[/tex] yard

So,

Therefore, area of 9 ft by 12 ft is = [tex]$9 \times \frac{1}{3} \times 12 \times \frac{1}{3} $[/tex]

                                                    = 3 x 4

                                                    = 12 square yard

Therefore, cost of carpeting 2 square yard = 12 x 15

                                                                       = $ 180
