O x+4)-7
O-5+X=-2

Point Form:

(x,2/7+4x/7)

Equation Form:

Answer:

A=1

Step-by-step explanation:

7(5a-4)-1=14-8a

35a-28-1=14-8a

35a-29=14-8a

43a-29=14

43a=43

a=1

Answer:

41/43

Step-by-step explanation:

7(5a - 4) - 1 = 14 - 8a

35a - 28 - 1 = 14 - 8a

35a - 27 = 14 - 8a

35a + 8a = 14 + 27

43a = 41

a = 41/43

Answer:

Last Choice / D

Step-by-step explanation:

you want to isolate v!

E = 1/2 m v^2

multiply both sides by 2

2E = mv^2

divide both sides by m

2E/m = v^2

square root both sides

v = ±[tex]\sqrt{2E/m}[/tex]

Answer:

[tex]D.v= \± \sqrt{\frac{2E}{m}}[/tex]

Step-by-step explanation:

[tex]We\ are\ given\ that,\\Kinetic\ Energy\ possessed\ by\ an\ object=\frac{1}{2}mv^2\\Hence,\\E_k=\frac{1}{2}mv^2\\2E=2*\frac{1}{2}mv^2 [Multiplying\ both\ the\ sides\ with\ 2]\\2E=mv^2\\\frac{2E}{m}=\frac{mv^2}{m}[Dividing\ both\ the\ sides\ by\ m]\\\frac{2E}{m}=v^2\\Now,\\As\ v\ could\ be\ positive\ or\ negative\ but\ its\ square(v^2)\ would\ always\ be\ positive.\\[/tex]

[tex](\± v)^2= v^2\\Hence,\\\frac{2E}{m}= (\±v)^2 \\\sqrt{\frac{2E}{m}} = \±v\\Or,\\ v= \± \sqrt{\frac{2E}{m}}[/tex]

Answer:

It flies 380 miles fewer

Step-by-step explanation:

The correct question is as follows;

Scientists are preparing two satellites to be launched. The equation y=820x represents the number of miles, y, that the satellite, Space Explorer B, flies in x hours. The satellite, Space Explorer A, flies 28800 miles in 24 hours. How many fewer miles does Space Explorer A travel in one hour than Space Explorer B?

Solution;

For explorer B

The equation is;

y = 8200x

This mean that in 1 hour, it flies 820 miles

For explorer A

28,800 miles in 24 hours

In one hour, we have 28,800/24 = 1,200 miles

The number of fewer miles that explorer A travels will be ;

1200 miles - 820 miles = 380 miles fewer

Step-by-step explanation:

the terms are 2k,15,m,3,n,7p.

variables are k,m,n,p

coefficients are 2,and 7

constants are 15 and 3

Answer:

k = 15

Step-by-step explanation:

4k - 2k = 2k

-21 - 11 = -10

2k - 10 = 20

30 - 10 = 20

2 × 15 = 30

Answer: C. f(x)=1.5x

Step-by-step explanation:

Here's the complete question:

In a direct variation equation f(x) = 6 when x = 4. what is the direct variation equation

A-f(x)=6x

B-f(x)=4x

C-f(x)=1.5x

D-f(x)=0.67x

The direct variation equation will be:

6 = kx

When x = 4, this will be:

6 = 4k

k = 6/4

k = 1.5

Therefore, the direct variation equation is: f(x)=1.5x

Answer:

  28k

Step-by-step explanation:

The perimeter is the sum of the four equal-length sides:

  P = 7k +7k +7k +7k

  P = k(7 +7 +7 +7)

  P = 28k . . . . perimeter of the rhombus

__

Of course, multiplication was invented to make repeated addition easier. Here, the perimeter is 4(7k) = 28k, no like terms to combine.

Answer:

x ≤ 2

Step-by-step explanation:

We can write out the inequality as: 3(x) ≤ 6

You have to divide 3 from both sides, so x ≤ 6/3 which is x ≤ 2.

Answer: $5.40

Step-by-step explanation:

1 and 2/3 yards costs $9

5/3 yards costs $9 <--- changes 1 and 2/3 to improper

5 * 1/3 yards costs $9 <---- 5/3 = 5 * 1/3

1/3 yard costs $9/5 = $1.80 <--- divides the ratio by 5

1 yard costs $1.80 * 3 = $5.40

Answer: x = 4/7

Explanation and steps is in the image below.

The solution to the given equation 6 - 2(x + 5)/3 = 4x is x = 4 /7.

The equation is defined as an algebraic statement that has a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question

6 - 2(x + 5)/3 = 4x

Apply the distributive property of multiplication,

6 - (2x + 10)/3 = 4x

(2x + 10)/3 + 4x = 6

2x/3 + 10/3 + 4x = 6

2x/3 + 4x = 6 - 10/3

Take the LCM in the above equation,

14x/3 = 8/3

14x = 8

x = 8 / 14

x = 4 /7

Thus, the solution to the given equation 6 - 2(x + 5)/3 = 4x is x = 4 /7.
