Answer:  The correct answer is (3x+1)(x-4)

Step-by-step explanation:

(3x+1)(x-4)

3x(x-4)            +               1(x-4)

3x^2 - 12x       +                  x-4

nine equals the quotient of a number and 54

       /\

9 = the quotient of a number and 54

             /\

9 =       will be division of a number and 54

Here's the solving step

Answer:

No. Correct is 7x - 10y = 6.

Step-by-step explanation:

The slope of the line is (-9-5)/(-12-8) = 7/10

y - 5 = 7/10(x - 8)

10y - 50 = 7(x - 8)

10y - 50 = 7x - 56

7x - 10y = -50 + 56

7x - 10y = 6.

Explanation:

Let's plug in x = 8 and y = 5. This is directly from the ordered pair (8,5).

7x - 10y = 3

7*8 - 10*5 = 3

56 - 50 = 3

6 = 3

We get a false equation at the end, which means the original equation is false when (x,y) = (8,5). Therefore, the point (8,5) is not on the line 7x-10y = 3. Furthermore it means that 7x-10y = 3 is not a good model since Devon wanted the line to pass through both given points.

If you were to plug in (x,y) = (-12,-9), then you would find the same thing happens. For each ordered pair, the left side results in 6. So if Devon were to change that "3" to "6", then it would be a good model as both points would be on the line. In other words, the standard form equation Devon should use is 7x-10y = 6. When solving for y, Devon would get y = (-7/10)x - 3/5

Below is visual confirmation that 7x-10y = 3 is not a good model. Both points are not on the line. The graph was made using GeoGebra.

Step-by-step explanation:

C= πd

d=√(24²+7²)=√(576+49)=√625=25

C=25π

Answer:

Step-by-step explanation:

First off, divide 24 by 2 as that would give you the radius of the circle

24cm / 2cm = 12cm

Next, use the formula to calculate the circumference of a circle and plug in radius:

C = 2 x π x r

   = 2 x π x 12cm

   = 75.40cm is the circumference

Step-by-step explanation: i got it right

The solution to the equation is a = 2

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

a = 2 ( 5 - 3a ) + 4

By distributive property , we get

a = 10 - 6a + 4

By combining the like terms , we get

a = 14 - 6a

By addition property of equality , we get

7a = 14

By division property of equality , we get

a = 2

Hence , the equation is solved and a = 2

What's 2.54 cm in inches?

To convert cm to inches, divide your cm figure by 2.54 or multiply it by 0.3937. As an example, let's say you have a piece of wood measuring 50cm and you want to convert it into inches. To get your answer, divide your cm figure by 2.54. So, 50 ÷ 2.54 = 19.685 inches.

Step-by-step explanation:

Answer: 2.54x12 is 30.48

We can write:

2.54x

Where 'x' is the number of inches.

Plug in 12 for 'x':

2.54(12)

30.48

So 12 inches is approximately 30.48 centimeters.

Answer:

∠ DAE = 130°

Step-by-step explanation:

ABCD is a parallelogram ( opposite sides are parallel )

The opposite angles of a parallelogram are congruent , then

∠ BAD = ∠ BCD = 65°

∠ ADE = ∠ BAD = 65° ( alternate angles )

Since DE = AE then Δ ADE is isosceles with 2 base angles congruent, that is

∠ DAE = ∠ ADE = 65°

Then

∠ BAE = ∠ BAD + ∠ DAE = 65° + 65° = 130°
