Answer:

option A

Step-by-step explanation:

here's your solution

=> 6x - 7y = 28

=> - 7y = 28 - 6x

=> - y = 28/7- 6x/7

=> -y = 4 - 6x/7

=> y = 6x/7 - 4

Answer:

9

Step-by-step explanation:

2/5 x 2 = 4/5

4/5 x 2, or 2/5 x 4 = 1 3/5

1 3/5 x 2, or 2/5 x 8 = 3 1/5

3 1/5 + 2/5, or 2/5 x 9 = 3 3/5

Answer:

65.44985

Step-by-step explanation:

V=πr2h 3=π·2.52·10  3≈65.44985

David is 1.94 meters tall.

Given that,

Shaun is 1.88 meters tall.

David is stated to be 6 centimeters taller than Shaun.

To determine David's height, we need to add the additional height to Shaun's height.

Since there are 100 centimeters in a meter, we can convert the 6 centimeters to meters by dividing it by 100: 6 cm / 100 = 0.06 meters.

Now, we can add this height to Shaun's height to find David's height:

1.88 meters + 0.06 meters = 1.94 meters.

Therefore, David is 1.94 meters tall.

I got this answer of the internet good luck lol

The length of ladder would be,

⇒ 14/√3 feet

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

We have to given that;

You leaned the ladder against your house at a 30° angle of elevation.

And, The foot of the ladder is 7 feet from the foot of the house.

Now,

Let the length of ladder = x

Hence, We can formulate;

⇒ cos 30° = 7 / x

⇒ √3 / 2 = 7 / x

⇒ x = 14 / √3 feet

Thus, The length of ladder would be,

⇒ 14/√3 feet

Answer:

D. 8[tex]\sqrt{2}[/tex]

Step-by-step explanation:

To find the diagonal of the square, you can use the Pythagorean theorem* to find the hypotenuse since the diagonal cuts the square into two right triangles with legs of 8 units in length:

If in a^2 + b^2 = c^2, a = 8 and b = 8,

8^2 + 8^2 = c^2 (put 8 as both the leg lengths in the equation)

128 = c^2 (calculate 8^2 and then add the two terms together)

c = 8[tex]\sqrt{2}[/tex] (square both sides)

So, the length of the diagonal is 8[tex]\sqrt{2}[/tex] units

*the Pythagorean theorem is a theorem used to find the sides lengths of a right triangle: a^2 + b^2 = c^2. a and b are the legs of the triangle, and c is the hypotenuse.

Trying to factor by splitting the middle term

3.1     Factoring  9v2-9v-1  

The first term is,  9v2  its coefficient is  9 .

The middle term is,  -9v  its coefficient is  -9 .

The last term, "the constant", is  -1  

Step-1 : Multiply the coefficient of the first term by the constant   9 • -1 = -9  

Step-2 : Find two factors of  -9  whose sum equals the coefficient of the middle term, which is   -9 .

     -9    +    1    =    -8  

     -3    +    3    =    0  

     -1    +    9    =    8  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Answer:

x + f(x) + g(x)

Step-by-step explanation:

(f+g) = f(x) + g(x)

Therefore, x + (f+g) = x + f(x) + g(x)

If you are given equations to go with f(x) and g(x), you would plug in those equations to the above expression then combine like terms to find the fully simplified expression equal to x + (f+g).

Answer:

$260,000

Step-by-step explanation:

Explanation:

Given the problem above, we solve for original value

Hence, in this case, we are given

percentage (35%) and the New Value ($351,000).

We can substitute this into the formula and solve for X

Let X be the original price, Hence, X = 100%

Therefore, $351000 = 135%

Divide both sides by 135

351000÷ 135 = 135÷135

2600 = 1%

Multiply both sides by 100

2600 * 100 = 1% * 100

$260000 = 100% = X

Hence, final answer is $260000

The equation is: y y = 5/4 * x - 13

Step-by-step explanation:

The slope-intercept y = mx + c form of a straight line is In this case we have a point, (x, y) and the slope, m so all we need is a value for c. Substitute into y = mx + c - 3 = 5/4 * (8) + c - 3 = 10 + c c = - 13 y = 5/4 * x - 13 The equation is: y the formula for the situation have a point, (x 1 ,y 1 ) and the slope, Or you can use where you (m) y-y 1 =m(x-x 1 ) y - (- 3) = 5/4 * (x - 8) y + 3 = 5/4 * x - 10 y = 5/4 * x - 13 Answer link < II
