Answer:

x = -13

Step-by-step explanation:

65 + 5x = 0

65 = -5x

divide by -5

-13 = x

Answer:

x = 13

Step-by-step explanation:

You have to get x by itself

so you divide 5 by 65

Then X is by itself and your answer is 5/65

Answer:

the answer is d

Step-by-step explanation:

so for one do y-intercept has to be at (0,25) so we can eliminate answer choices B and C

the reason why it is not a is because a is moving out of constant rate of 25 when it needs to be moving at a constant rate like 10 D is the answer because it's moving at a constant rate of 10 and it has a y intercept of (0,25)

Step-by-step explanation:

70*+ 30* (* means degree)

the 30 degree is only a imagination....

70+30=90*. so x is equal to 30*

9514 1404 393

Explanation:

We can start with the relations ...

  [tex]\displaystyle\left(x+\frac{1}{x}\right)^3=\left(x^3+\frac{1}{x^3}\right)+3\left(x+\frac{1}{x}\right)\\\\\left(x+\frac{1}{x}\right)^5=\left(x^5+\frac{1}{x^5}\right)+5\left(x^3+\frac{1}{x^3}\right)+10\left(x+\frac{1}{x}\right)\\\\\textsf{From these, we can derive ...}\\\\x^5+\frac{1}{x^5}=\left(x+\frac{1}{x}\right)^5-5\left(\left(x+\frac{1}{x}\right)^3-3\left(x+\frac{1}{x}\right)\right)-10\left(x+\frac{1}{x}\right)[/tex]

  [tex]\displaystyle x^5+\frac{1}{x^5}=\left(x+\frac{1}{x}\right)^5-5\left(x+\frac{1}{x}\right)^3+5\left(x+\frac{1}{x}\right)\right)\\\\x^5+\frac{1}{x^5}=3^5 -5(3^3)+5(3)\\\\=((3^2-5)3^2+5)\cdot3=(4\cdot9+5)\cdot3=(41)(3)\\\\=\boxed{123}[/tex]

-13-4x=x+7

+13         +13

-4x=x+20

-x    -x

-5x=20

/-5   /-5

x=-4

Answer:

4u^3 + 6u^2 - 7u + 9

Step-by-step explanation:

(2u3 + 6u2 + 3) + (2u3 – 7u + 6)

Remove the brackets.

2u^3 + 6u^2 + 3 + 2u^3 - 7u + 6

2u^3 + 2u^3 = 4u^3

6u^2

- 7u

3 + 6 = 9

Now just read down

4u^3 + 6u^2 - 7u + 9

The answers don't seem to connect with the question. Is U equal to something?

Answer:

x = 125

y = 55

Step-by-step explanation:

opposite angles in a parallelogram are equal

we also know that this is true because

(2(125)) + (2(55)) = 360

Answer: This is a perfect square trinomial. You are trying to find the binomials that multiply to that. In order to do that, you do the following.

Multiply 2x^2 by 4 (A times C)

Find what numbers multiply to give you 8 and add to give you 7.

When you do this, you will notice that there are no numbers that do this. That makes your answer D. NONE OF THESE.

Step-by-step explanation:

Answer:

J

Step-by-step explanation:

F is impossible because -1 x 4 = -4

G is impossible because 1 x -4 = -4

Try to solve H

2x^2+8x+x+4 = 2x^2+9x +4 (is not correct)

Answer:

PV= $100,402.86

Step-by-step explanation:

To calculate the present value, first, we need to determine the future value using the following formula:

FV= {A*[(1+i)^n-1]}/i

A= semiannual deposit

n=12*2= 24 semesters

i= 0.12/2= 0.06

FV= {8,000*[(1.06^24) - 1]} /  0.06

FV= $406,524.62

Now, the present value:

PV= FV / (1+i)^n

PV= 406,524.62 / 1.06^24

PV= $100,402.86

Answer:

m<CAB = 59

m<ACB = 59

Step-by-step explanation:

4x - 41 = 2x + 9

2x - 41 = 9

2x = 50

x = 25

m<CAB: 4x - 41

4(25) - 41

59

m<ACB: 2x + 9

2(25) + 9

59

Answer:

b = 4 inches, c = ~5.66 inches

Step-by-step explanation:

The triangle is isosceles so b is equal to the adjacent side. Use the Pythagorean theorem to find c.

Answer:

To find out rectangle do:

lxw

7x3=21

21+21=42

Answer:

I believe it is because it is being transferred to kinetic energy

Step-by-step explanation:

As the puck falls, it loses potential energy and gains kinetic energy because it is now falling, which causes movement due to gravity. And as we know, kinetic energy is energy which a body possesses by virtue of being in motion

Answer:

5-(-7)=5+7

Step-by-step explanation:

keep in mind that two negatives make a positive. therefore it would be 5+7=5+7. i hope this helps :)
