Step-by-step explanation:

[tex](8x^{2} - 9y^{2} - 4x) + (x^{2} - 3y^{2} -7x)\\(8x^{2} + x^{2} ) + (-9y^{2} - 3y^{2} ) + (-4x - 7x)\\9x^{2} - 12y^{2} - 11x[/tex]

In the first step, I rearranged the equation and put like terms together.

Then I just combined the like terms.

Answer:

497.6 cm to 1 decimal place.

Step-by-step explanation:

→ Square root the area to find the length

√15476 = 124.4025723

→ Multiply the answer by 4 to get the perimeter

124.4025723 × 4 = 497.6102893

Answer:

497.6 cm

Step-by-step explanation:

Perimeter = 4 x a

Since area is given we must square root a

P = 4 x square root ([tex]\sqrt{15476}[/tex])

P = 4 x (124.40)

P = 497.6 cm

I just put the number of fiction books over the number of nonfiction books. Then I plugged it into a calculator and if the answer was the same as 15/22, then it was right!

2385/3498=15/22

3945/5786=15/22

2340/3588≠15/22

2480/3410≠15/22

4650/6820≠15/22

2310/3696=15/22

Answer: Y=20

Step-by-step explanation:

X is doubled from 3 to 6 meaning that y is also doubled.

Double 10 is 20 so y=20.

Answer:

8/3, or 2 if you want a whole number

Step-by-step explanation:

Well, the simple answer is 2/(3/4). This is nothing but 2*4/3, which is just 8/3. (I used the theorem that states that dividing is the same as multiplying by the reciprocal)

Answer:

They are same side interior angles. Angle A measures 55°.

Step-by-step explanation:

[tex]\cos \theta = \dfrac{\text{Base}}{\text{Hypotenuse}}\\\\\\\cos 45^{\circ} = \dfrac{s}{10\sqrt 2}\\\\\implies \dfrac 1{\sqrt2} = \dfrac{s}{10\sqrt 2}\\\\\\\implies \dfrac s{10} = 1\\\\\implies s= 10[/tex]

Answer:

The next day they will both run on the path is July 27th.

We can find this by making columns writing every date and seeing when they intersect.

8                   10

12                  15

16                 20

20

We can then add this to the current date to find the date they will next run together.

I cant even see anything can you reupload your answer, please?

Step-by-step explanation:

Using the trigonometry ratio and Pythagorean Theorem, the value of b in the triangle is: 4.

Recall:

Given the trigonometry ratio of sin A = 3/5

Recall that, sin ∅ = opp/hyp (SOH)

Thus, this means that, in sin A = 3/5,

Thus, find the value of b by applying the Pythagorean theorem.

[tex]b = \sqrt{c^2 - a^2}[/tex] (Pythagorean Theorem)

[tex]b = \sqrt{5^2 - 3^2}\\\\\mathbf{b = 4}[/tex]

Therefore, using the trigonometry ratio and Pythagorean Theorem, the value of b in the triangle is: 4.

Answer:

4p+23

Step-by-step explanation:

I'm guessing you add all of the sides to get the perimeter, so 4p+5+10+8 is 4p+23.

Answer:

x=10

Step-by-step explanation:

Make 2x the only variable on the left side of the equation. Do that by taking 3 and 5 to the left. Note: if you move/transpose any number the sign must change.

2x = 18+5-3

2x=20

Divide both sides of the equation by 2 to make x the only variable left.

x=10

The correct answer is E. A fundamental basis of regression analysis is the assumption of the existence of two independent variables for every dependent variable.

Regression analysis is a statistical method that examines the dependence of a response variable on selected explanatory variables.

When studying the dependence between quantities and trying to describe a given functional dependence on a given formula, it is assumed that the dependence consists of a precisely determinable component and a random component. The relationship with this assumption is called the regression model.

Answer:

you know, you can't post more than one question

Step-by-step explanation:

Step-by-step explanation:

1. First divide by the leading term, making the polynomial monic.

2. Then, given x

2 + a1x + a0, substitute x = y − a1  to obtain an equation without the linear term.

(This is the “depressed” equation.)

3. Solve then for y as a square root. (Remember to use both signs of the square root.)

4. Once this is done, recover x using the fact that x = y − a1
