if y varies directly as the square if x. If y=27 when x=3, find x when y=81?

Answers

Answer:

x = 3[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Given y varies directly as x², then the equation relating them is

y = kx² ← k is the constant of variation

To find k use the condition y = 27 when x = 3 , then

27 = k × 3² = 9k ( divide both sides by 9 )

3 = k

y = 3x² ← equation of variation

When y = 81, then

81 = 3x² ( divide both sides by 3 )

27 = x² ( take the square root of both sides )

x = [tex]\sqrt{27}[/tex] = [tex]\sqrt{9(3)}[/tex] = 3[tex]\sqrt{3}[/tex]

This Diagram Shows a Square (6x-1)cm (4x+6)cm. Find the length of the side of the square. Your final answer must say, Side = ...cm

Answers

Given:

Diagram Shows a Square (6x-1)cm (4x+6)cm.

To find:

The length of the side of the square.

Solution:

We know that, all sides of a square are equal. So,

[tex]6x-1=4x+6[/tex]

[tex]6x-4x=1+6[/tex]

[tex]2x=7[/tex]

Divide both sides by 2.

[tex]x=\dfrac{7}{2}[/tex]

[tex]x=3.5[/tex]

Now, the side of the square is

[tex]Side=6x-1[/tex]

[tex]Side=6(3.5)-1[/tex]

[tex]Side=21-1[/tex]

[tex]Side=20\text{ cm}[/tex]

Therefore, the length of the side of the square = 20 cm.

Answer:

Step-by-step explanation:

which recursive formula can be used to represent the sequence 2,5,8,11,14,..
a. a1=2 an-1=an+3
b. a1=0 an=an-1+3
c. a1=2 an=an-1-3
d. a1=2 an=an-1+3​

Answers

The recursive formula that is used to represent the sequence 2,5,8,11,14,... is a(n)=a(n-1)+3.

Sequence

A sequence is an ordered set of numbers that frequently maintain a pattern.

How to find a recursive formula that is used to represent the given sequence?

The given sequence is 2,5,8,11,14,..

The first term is 2.

So, a(1)=2

The common difference is (5-2), that is 3.

So, the recursive formula is a(n)=a(n-1)+3

Therefore, the recursive formula that is used to represent the sequence 2,5,8,11,14,... is a(n)=a(n-1)+3.

Thus, the correct option is (d)

A certain cookie recipe calls for 3 cups of flour to make one batch of cookies. Which
of the following graphs BEST represents the relationship between the amount of
flour and the number of batches of cookies that can be made using this recipe?

Answers

Answer:

the answer is the one similar to the one highlighted in purple, but the line should go through the points (3,1), (6,2), (9,3), (12,4)... so on and so forth

Step-by-step explanation:

We want to see which graph represents the relationship between the number of cups of flour and the number of batches of cookies that can be made with the recipe. The graph can be seen at the end.

So, we know that for every 3 cups of flour, we can make 1 batch of flour.

This relation can be written as:

y = (1/3cups)*x

Where y is the number of batches of cookies that you get, and x is the number of cups of flour that you use.

The graph of this line can be seen in the image below:

The ratio of the numerator to the denominator of a fraction is 2 to 3. If both the numerator and the denominator are increased by 2, the fraction becomes . What is the original fraction?

Answers

Answer:

a) If both the numerator and the denominator are increased by 2, the fraction becomes?

= 4/5

b) What is the original fraction?

= 2/3

Step-by-step explanation:

The ratio of the numerator to the denominator of a fraction is 2 to 3.

a) If both the numerator and the denominator are increased by 2, the fraction becomes .

2:3 = 2/3

We are told that both numerator and denominator are increased by 2, hence:

2 + 2/3 + 2

= 4/5

Answer:

All real numbers are solutions.

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

4(3x+2)=16x+7−4x+1

(4)(3x)+(4)(2)=16x+7+−4x+1(Distribute)

12x+8=16x+7+−4x+1

12x+8=(16x+−4x)+(7+1)(Combine Like Terms)

12x+8=12x+8

12x+8=12x+8

Step 2: Subtract 12x from both sides.

12x+8−12x=12x+8−12x

8=8

Step 3: Subtract 8 from both sides.

When you multiply the following binomials, what is the linear term (the term with x)?

(X+3) (X-5)

Answers

Answer:

We conclude that 2x is the linear term with x.

Step-by-step explanation:

Given the expression

[tex]\left(x+3\right)\left(x-5\right)[/tex]

Multiplying the binomials

Apply FOIL method:

[tex]\left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]

[tex]\left(x+3\right)\left(x-5\right)=xx+x\left(-5\right)+3x+3\left(-5\right)[/tex]

Apply +(-) = - rule

                      [tex]=xx-5x+3x-3\cdot \:5[/tex]

simplify

                      [tex]=x^2-2x-15[/tex]

Here, 2x is the linear term with x.

It is called a linear term because the exponent of the variable is raised to the power of 1.

In other words, the degree of the linear term is 1.

Therefore, we conclude that 2x is the linear term with x.
