slove for x : 3x + 4 = 9x + 3

Answer:

x = 17.55 (rounded to nearest hundredth)

Step-by-step explanation:

Slant length = [tex]\sqrt{a^{2}+b^{2}}[/tex]

We just need to put in the values that we know first.

18 = [tex]\sqrt{4^{2}+x^{2}}[/tex]

18 = [tex]\sqrt{16+x^{2} }[/tex]

18² = 16 + x²

324 = 16 + x²

x² = 324 - 16

   = 308

x = [tex]\sqrt{308}[/tex]

x = 17.55 (rounded to nearest hundredth)

Answer:

17.54

Step-by-step explanation:

Use the pythagorean theorem, c would be 18 due to it being the diagonal side.

4^2+x^2=18^2

16+x^2=324

324-16=308

take the square root of 308 and you'll get the answer

x = 4

Step-by-step explanation:

Pull out like factors:  7x - 28  =   7 • (x - 4)

Solve:  x-4 = 0

Add  4  to both sides of the equation: x = 4

Answer:

Width of the rectangle is: [tex]\mathbf{Width= 9x^6 y^4}[/tex]

Option C is correct.

Step-by-step explanation:

Area of rectangle = [tex]54x^9y^8[/tex]

Length of rectangle = [tex]6x ^ 3y^4[/tex]

We need to find width of rectangle.

The formula used is:

[tex]Area\:of\:rectangle=Length\times Width\\Width=\frac{Area\:of\:rectangle}{Length}[/tex]

Putting values in the formula to find Width of rectangle

[tex]Width=\frac{Area\:of\:rectangle}{Length}\\Width=\frac{54x^9y^8}{6x^ 3y^4}[/tex]

Using the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex]

and simplifying the terms we get

[tex]Width=\frac{54x^9y^8}{6x^3y^4}\\Width=9x^{9-3} \: y^{8-4}\\Width=9x^6 y^{4}[/tex]

So, Width of the rectangle is: [tex]\mathbf{Width= 9x^6 y^4}[/tex]

Option C is correct.

Answer:

No

Step-by-step explanation:

The two shown sides would have to be and equal solved number.

They are not.

Orange is the correct answer.

Step-by-step explanation:

h(x) = (x + 9)(x² - 10x + 25) = (x + 9)(x - 5)²

When h(x) = 0, (x + 9) = 0 or (x - 5)² = 0.

=> x = -9 or x = 5.

Hence there are 2 distinct real roots of h(x).

Step-by-step explanation:

15x+10+6x+2=180 (add up to we 180 because they are alternate eachother

21x+12=180 combine like terms

21x=178 subtract 12 from both sides

x~~8.5 divide both sides by 21

Step-by-step explanation:

The relationship between the cost of cookies and the number of cookies is

a proportional relationship.

Correct response:

The function of the given graph for the cost of cookies at store A is found as follows;

The graph is a straight line passing through the origin, therefore, the equation is of the form;

y = m·x

The cost of 2 cookies = $0.5

Therefore;

The cost of 1 cookie at store A = $0.5 ÷ 2 = $0.25

Therefore, the cost of y cookies = 0.25·x

Where;

x = The number of cookies

The equation representing the cost y for x cookies in store B in dollars is given as follows;

y = 0.30·x

Therefore, the cost of 1 cookie at store B = $0.30 × 1 = $0.30

Therefore;

Answer:

How many apples did Mr. Rozario buy?

16 apples

How many oranges did Mr. Rozario buy? 40 oranges

Step-by-step explanation:

From the question, we know that:

The ratio of the number of apples to the number of oranges are 2:5.

We represent the total number of fruits as x

Let

The number of apples he bought be represented as 2x

The number of oranges he bought be represented by

= 5x

He gave 3/4 of the apples to his sister and 34 oranges to his brother.

This means now, the number of apples he has left =1 - 3/4(2x) = 1/4(2x)

The number of oranges he has left = 5 - 34

The ratio of the number of oranges to the number of apples that he has now is 2:3.

1/4(2x) : 5x - 34 = 2:3

x/2:5x - 34 = 2:3

= x/2/5x-34 = 2/3

Cross Multiply

(x/2)3 = 5x - 34(2)

3x/2 = 10x - 68

Cross Multiply again

3x = 2(10x - 68)

3x = 20x - 136

20x - 3x = 126

17x = 126.

x = 126/17

x = 8

Hence:

The number of apples he bought be represented as 2x

So: 2 × 8 = 16 apples

The number of oranges he bought be represented by

= 5x

so: 5 × 8 = 40 oranges

Therefore, the number of Apples Mr Rosario bought is 16 apples

The number of oranges Mr Rosario bought is 40 oranges

Step-by-step explanation:

took a test and got it right

The value of the f(7) is -3 if the function is f(x) = x – 10 after plugging x = 7 in the function.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = x -10

The above function represents the linear function.

To find the value of f(7) plug x = 7 in the function.

f(7) =  7–10

f(7) = -3

Thus, the value of the f(7) is -3 if the function is f(x) = x – 10 after plugging x = 7 in the function.
