Answer:

12x + y

Step-by-step explanation:

(5x - 3y) + (7x + 4y)

-you need to distribute a 1 from the  1(7x + 4y) and drop the 5x - 3y

5x - 3y + 7x + 4y

- combine like terms

5x + 7x = 12x   &   -3y + 4y = 1y or just y

12x + y

Answer:

The estimated distance is 8.1cm.

The actual distance is 8.106cm.

Step-by-step explanation:

Given that the Pythogorean Theorem, c² = a² + b². Then substitute the following values into the formula :

{c}^{2}  =  {a}^{2}  +  {b}^{2}

Let a = 5.1cm,

Let b = 6.3cm,

{c}^{2}  =  {5.1}^{2}  +  {6.3}^{2}

{c}^{2}  = 26.01 + 39.69

{c}^{2}  = 65.7

c =  \sqrt{65.7}

c = 8.106cm \: (3d.p)

xeze [42]

Answer:

The distance between two points on a number line can be found by taking the <u>absolute value</u> of the <u>difference</u> of the coordinates.

Step-by-step explanation:

  • Every point can be paired with a number on a number line
  • The coordinate is the number associated with a point
  • To find the distance between point A and B you subtract the coordinates in any order you like and take the absolute value.

Could someone help me finding out the missing answers?
Tema [17]

Answer:

See below.

Step-by-step explanation:

The Slope of PQ is (v - z) / (w - x).

The slope of P'Q' =

(v + b) - (z + b)

---------------------   =   (v - z) / (w - x)

(w + a - (x + a)

Both lines have a slope that is (v - z)/ (w - x).

So both lines are parallel.

A student gets 9 out of 15 problems correct on a homework assignment.
Alex777 [14]

Answer:40%.

Since the student got 60% correct, the remaining percentage would be the part they got incorrect.

I got 60% by translating 9/15 into a decimal and moving the decimal point to create a percentage.

Hope this helps!
