Ede4ka [16]2 years ago
5 0

Answer:maybe this helps

Step-by-step explanation: k*(x)-(2*x^2+7)=0

STEP

1

:

Equation at the end of step 1

kx - (2x2 + 7) = 0

STEP

2

:

Trying to factor a multi variable polynomial

2.1 Factoring kx - 2x2 - 7

Try to factor this multi-variable trinomial using trial and error

Factorization fails

Equation at the end of step

2

:

kx - 2x2 - 7 = 0

STEP

3

:

Solving a Single Variable Equation:

3.1 Solve kx-2x2-7 = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

We shall not handle this type of equations at this time.

Please help me and show how you worked out.

Answer: The sequence rule is division. 80 divided by 2 = 40 divided by 2 = 20 divided by 2 = 10 and 10 / 2 equals 5.

Step-by-step explanation:

The sequence is divided by 2 because when you divided 80 by 2, it equals the second pattern in the sequence, 40.

I worked it out by dividing every number by 2 and getting the same numbers in the pattern, I checked by doing the opposite, 40 x 2 = 80.

Hope this helps!

Answer:

equation: 4x+6=9

x=0.75

Step-by-step explanation:

4x+6=9

subtract 6 from both sides

4x+6-6=9-6

4x=3

divide by 4 on both sides

4x÷4=3÷4

x=0.75

According to Greek mathematician Zeno, if each bounce of a ball is half the height of the bounce before it,the ball will never s
vovikov84 [41]
From the diagram associated with this question it can be seen that the first bounce was 1 units high, thus the second bounce is 1 / 2 = 0.5 units high and the third bounce is 0.5 / 2 = 0.25 = 1/4 units high.

Given that B represents the second bounce and C represents the first bounce, the <span>fractions in hundredths that should be written at points B is 0.50 while at point C is 0.25</span>
