Change y-7=m(x-4) to standard form
Ivan

Answer:

  mx -y = 4m -7

Step-by-step explanation:

Standard form is ...

  ax +by = c

where a, b, c are mutually prime integers and a > 0.

If we assume m > 0, then we need to collect the variable terms on the right side of the equation, so the coefficient of x will be positive.

  y -7 = mx -4m . . . . eliminate parentheses

  -7 = mx -y -4m . . . . subtract y

  4m -7 = mx -y . . . . . add 4m

  mx -y = 4m -7 . . . . . . standard form

Help me please!!!!!!!!
pogonyaev

Answer:

1) 4

2) 1.5

3) 8

4) 1

5) 5

6) 9

Step-by-step explanation:

<h3>1)</h3><h3> √16</h3>

= √(4x4)

= √(4)²

<h3>= 4</h3>

<h3>2)</h3><h3>√2.25</h3>

= √(9/4)

= √(3x3)/(2x2)

= √(3)²/(2)²

= 3/2

<h3>= 1.5</h3>

<h3>3)</h3><h3>6² ÷ 9 x 2 </h3>

= 36 ÷ 9 x 2

= 36 x 1/9 x 2

= 36/9 x 2

= 12/3 x 2

= 4 x 2

<h3>= 8</h3>

<h3>4)</h3><h3>12-2 / 6+4</h3>

= 10/10

<h3>= 1</h3><h3 /><h3>5)</h3><h3>√(16+9)</h3>

= √(25)

= √(5x5)

= √(5)²

<h3>= 5</h3><h3 /><h3>6)</h3><h3>63 ÷ 3² + |2|</h3>

= 63 ÷ 9 + |2|

= 63/9 + |2|

= 21/3 + |2|

= 7 + |2|

<h3>= 9</h3>

MAXImum [283]
We have to convert the measurements
the tray is 60 cm by 50 cm

if the cake tin is 25 cm in diameter, it will fit just 4 cakes because we have a length of 60 cm (will have 10 cm left over) and a width of 50 cm

Elanso [62]
The answer is 4.5.

The formula for a rectangle is A = lw. Substitute the formula, so it'll be 27 = (2x - 3) * x. Evaluate the formula.

Hope this helps you! And rate me to see if I did it right. Thanks!
