If a+b(c+d)/e =1 which of the variable a,b,c,d, or e cannot be 0?

A.) b

B.) e

C.) a

D.) d

E.) c

Answer:

If the question is asking for a solution for both, then only point (0,2)

Point (0,2) is a solution to both equations

Point (5,3) is a solution to neither (meaning not any of the equations)

Point (-2, 16) is not a solution to the first equation, but is to the second

Point (-4, -9) is a solution to the first, but not to the second.

Step-by-step explanation:

Final answer:

By substituting the x and y values from each ordered pair into the two given equations, we can determine whether the ordered pairs (0,-2), (5,3), (-2,16), and (-4,-9) are solutions. An ordered pair is a solution if it satisfies both equations of the system.

Explanation:

To determine whether each ordered pair is a solution to the system of equations:

7x - 4y = 8

y = -9x - 2

We will substitute the x and y values from each ordered pair into both equations.

For the ordered pair (0,-2), substitute x = 0 and y = -2:

7(0) - 4(-2) = 8 satisfies the first equation, and -2 = -9(0) - 2 satisfies the second equation, so (0,-2) is a solution.

Repeating this process for the other ordered pairs, (5,3), (-2,16), and (-4,-9), will reveal whether they satisfy both equations.

If both equations are satisfied by a particular ordered pair, then that ordered pair is a solution to the system of equations.

Answer:

  8.284 × 10^4 m^2

Step-by-step explanation:

The area is the product of length and width:

  (5.45·10^5 m)·(0.152 m) = 0.8284·10^5 m^2 = 8.284·10^4 m^2

Answer:

x = -17/2 or -8.5

Step-by-step explanation:

-4x+8 = 42

Subtract 8 from each side

-4x+8-8 = 42-8

-4x = 34

Divide each side by -4

-4x/-4 = 34/-3

x = -17/2

x = -8.5

Step-by-step explanation:

Answer:

a) the temperature is y = 16° C at 9 AM.

b) The probability of selecting 2 vowels at the same time is 2.8%

Step-by-step explanation:

a)

Temperature = y=?

Time = x = 9 A.M

The given equation is:

[tex]y = 19 + 6 sin (\frac{\pi }{12}(x-11))[/tex]

Putting x = 9 and solving

[tex]y = 19 + 6 sin (\frac{\pi }{12}(9-11))\\y = 19 + 6 sin (\frac{\pi }{12}(-2))\\y = 19 + 6 sin (\frac{-\pi }{6})\\y = 19 + 6(-0.5)\\y = 19 - 3\\y = 16[/tex]

So, the temperature is y = 16° C at 9 AM.

b)

WORD CLEMSON

Total Words = 7

Vowels = e, o = 2

Probability of selecting 2 vowels at the same time = P(2 Vowels) =?

We will use the formula of combinations nCr = n! / r! (n-r)!

As we are selecting three letter out of 7, the sample space will be 7C3

And

As there are only two vowels in the given word, and we have to find the probability of selecting two vowels so our event space will be 2C2.

P(2 Vowels) = 2C2 / 7C3

                    = 1/35

                    = 0.028 = 2.8%

So, The probability of selecting 2 vowels at the same time is 2.8%

Answer:

answer is C

Step-by-step explanation:

Answer: Area of shape which is 15 cm is 312.5 square cm.

Step-by-step explanation:

Since we have given that

Area of shape of 12 cm = 200 sq. cm

We need to find the area of shape of 15 cm.

As we know the "Area similarity theorem" which states that ratio of areas of two similar shapes is equal to the square of ratio of corresponding sides.

So, it becomes,

[tex]\dfrac{12^2}{15^2}=\dfrac{200}{x}\\\\\dfrac{144}{225}=\dfrac{200}{x}\\\\144x=200\times 225\\\\144x=45000\\\\x=\dfrac{45000}{144}\\\\x=312.5\ cm^2[/tex]

So, Area of shape which is 15 cm is 312.5 square cm.

The area of shape B which is of 15 [tex]\text{cm}[/tex], is 312.5 [tex]\text{cm}^2[/tex].

Given information:

The two shapes A and B are given

The dimensions of shape A is 12 [tex]\text{cm}[/tex]

The area of the shape A is 200 [tex]\text{cm}^2[/tex]

Now, we need to calculate the area of the shape of 15 [tex]\text{cm}[/tex]

As we know that area will be square of the given values in the question.

So, according to the question:

[tex]\frac{A^2}{B^2} =\frac{200}{x}[/tex]

[tex]\frac{12^2}{15^2} =\frac{200}{x}\\\\\frac{144}{225}=\frac{200}{x} \\\\x=(200\times 225)/144\\\\x=312.5 \text{cm}^2[/tex]

Hence, the area of shape B which is of 15 cm, is 312.5 [tex]\text{cm}^2[/tex].

table 8.50

Step-by-step explanation:

The original price of the shirt must be $15 if a 20% discount resulted in the final price becoming $12

The original price of the shirt is $15.

Discount refers to the condition of the price of a bond that is lower than the face value. The discount equals the difference between the price paid for and it’s par value.

Discount is a kind of reduction or deduction in the cost price of a product. It is mostly used in consumer transactions, where people are provided with discounts on various products. The discount rate is given in percentage.

Discount = Original price - Buying Price

Given,

Buying price of the shirt john bought = $12

Discount on shirt John bought = 20% of the original price

Let, the original price be x

then,

discount = 20% of x = 20x/100

Discount = Original price - Buying Price

20x/100 = x - $12

x = $12 + 20x/100

x = ($1200 + 20x)/100

100x = $1200 + 20x

80x =$1200

x = $1200/80

x = $15

Hence, the shirt cost $15 originally.

Step-by-step explanation:

f(x) = x^2 - 3x

f(f(x)) = (x^2 - 3x)^2 - 3(x^2 - 3x)    (Replacing the x in f(x) by x^2 - 3x).

when f(f(x) = f(x):

(x^2 - 3x)^2 - 3(x^2 - 3x)  = x^2 - 3x

(x^2 - 3x)^2 - 4(x^2 - 3x) = 0

x = 5

Step-by-step explanation:

The line segment divides the sides in proportion, that is

[tex]\frac{14}{10}[/tex] = [tex]\frac{2x-3}{x}[/tex] ( cross- multiply )

10(2x - 3) = 14x ← distribute left side

20x - 30 = 14x ( subtract 14x from both sides )

6x - 30 = 0 ( add 30 to both sides )

6x = 30 ( divide both sides by 6 )

Answer:

Then, a=-1 and b=-1

Step-by-step explanation:

We need to solve the following system of equations using the adition method:

2a+3b=-1       (i)

3a+5b=-2      (ii)

First, we multiply the equation (i) by -3 and the equation (ii) by 2, so we get:

-6a-9b=3

6a+10b=-4

Adding the two equations we have:

-6a-9b=3

6a+10b=-4

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

 0  + b = -1

Then b=-1. Now, let's substitute the value of b into equation (i):

2a+3b=-1

2a + 3(-1) = -1

2a -3 = -1

2a = 2

a = 1

Then, a=-1 and b=-1

Answer:

a = 1 and b= -1

Step-by-step explanation:

It is given two equations,

2a + 3b = -1  and

3a + 5b = -2  

To find the solution of given equations

Let, 2a + 3b = -1   ----(1)

3a + 5b = -2   ------(2)

(1) * -3 ⇒

-6a - 9b = 3    ----(3)

(2) * 2 ⇒

6a + 10b = -4   -----(4)

(3) + (4 )⇒

-6a - 9b = 3    ----(3)

6a + 10b = -4   -----(4)

  0 + b  = -1

(1) ⇒ 2a + 3b = -1  

2a + (3 * -1) = -1

2a = -1 + 3 = 2

a = 2/2 =1

Therefore, a = 1 and b = -1

YOU CAN HAVE 4 MORE HOURS WITH THE PHOTO BOOTH

Step-by-step explanation:

500 + 50 IS 550 THATS ONE HOUR ADDED 550+50 = 600 THATS 2 HOURS 600 + 50=650 THATS 3 HOURS 650+50= 700 SHE GOT IT FOR 4 HOURS IN TOTAL SHE HAD IT FOR 6 HOURS COUNTING THE 2 HOURS FOR IT AT THE PARTY . PERIODDT.....

Cindy can rent the photo booth for a maximum of 4 additional hours beyond the first two hours included in the base fee, given her budget of $700.

The student is asking how many additional hours Cindy can rent a photo booth for her party, given her budget constraints. Initially, there is a $500 fee for two hours, and each additional hour costs $50. Cindy has a budget of $700 in total, which means she can spend $200 on additional hours beyond the first two hours included in the base fee. To calculate the maximum number of additional hours, we divide the additional budget ($200) by the cost per additional hour ($50).

So, the calculation is
$200 / $50 = 4 additional hours.

Cindy can thus rent the photo booth for a maximum of 4 additional hours without exceeding her budget of $700.
