Which of these points lies on the line discribed by the equation below? y-4= -2(x-6)
Basile [38]

Answer:

C, (6,4)

Step-by-step explanation:

The points (x,y) that lie on the line must fit into the equation correctly. So, we can test out the 4 options to see whether they fit correctly into the equation.

A:

y-4

= -4 -4 = -8

-2(x-6)

= -2 (-6-6)

= 24

Since -8≠24, so A is incorrect.

B:

y -4 = -6-4 = -10

-2(x-6) = -2 (-4-6) = 20

-10≠20, so B is incorrect.

C:

y-4 = 4 -4 = 0

-2(x-6) = -2(6-6) = 0

Both sides are equal. C is correct.

But lets test D out too.

y-4 = 6-4 = 2

-2(x-6) = -2(4-6) = 4

2≠4, so D is incorrect.

Please help explanation if possible
stira [4]

Answer:

y = 2x + 7

Step-by-step explanation:

Use Point Slope Form since we are given the slope and coordinates. Why is the slope 2x?

<em> </em><em>In</em><em> </em><em>Depth</em><em>:</em><em> </em><em>Parallel lines never touch so</em><em> </em><em>they</em><em> </em><em>are</em><em> </em><em> Lines that have same slope but different y intercept</em><em>.</em><em> An example is a square. A square has four parallel sides. The upper and lower sides will never touch because they are the same slope and they both have a finite distance vertically between them. </em>

<em>Back</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>question</em><em>,</em><em> </em><em>let</em><em> </em><em>use</em><em> </em><em>the</em><em> </em><em>Point</em><em> </em><em>S</em><em>lope</em><em> </em><em>Form</em><em>,</em>

<em>y -  y_{1} = m(x -  x_{1})</em>

<em>Where</em><em> </em><em>y1</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>y</em><em> </em><em>coordinate</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>given</em><em> </em><em>point</em><em>,</em><em> </em><em>m</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>slope</em><em> </em><em>and</em><em> </em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>x</em><em> </em><em>coordinates</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>given</em><em> </em><em>points</em><em>.</em>

<em>Substitute</em><em> </em>

<em>y  - ( - 1) = 2(x - ( - 4)</em>

<em>y + 1 = 2(x + 4)</em>

<em>Simplify</em>

<em>y + 1 = 2x + 8</em>

<em>y = 2x + 7</em>

length =8W -5

W+ W + 8W-5 +8W-5 = 115

2W + 16W -10

18W-10=115

18W =105

W = 5 and 5/6

Find the absolute maximum value of the function (picture shown)
hammer [34]

Answer:

  1

Step-by-step explanation:

The maximum on the first interval is at x=0, where 2·0 +1 = 1.

The maximum on the second interval is near x=0, where the function value is near 0² +1 = 1.

The absolute maximum value of the function is 1.
