8 0

Answer:

Step-by-step explanation:

The points given are: (1,-4), (7,-7), (13,-10), (19,-13)

They line up to a straight line with slope:

((-4)-(-7))/(1-7) = 3/-6 = -1/2

The equation in point-slope form is

(y-(-4)) = -1/2(x-1)

y+4 = -1/2(x-1)

A is the right answer.

Answer:

Step-by-step explanation:

there is a linear relationship

from the table, x changes by +6, y changes by -3 every time

so that means the slope is constant i.e. its a straight line

slope=(y2-y1)/(x2-x1)=-3/6

= -1/2

take the 1st pt, ( 1, -4 )

(y-(-4)) = slop * (x-1)

y+4 = -1/2*(x-1)

ans is A

4x -5 = 2(2x +1)<br> I need help
Nostrana [21]

Answer:

No Solution

Step-by-step explanation:

4x-5=2\left(2x+1\right)

Expand:

4x-5=2* \:2x+2* \:1

4x-5=4x+2

Add 5 to both sides:

4x-5+5=4x+2+5

4x=4x+7

Subtract 4x from both sides:

4x-4x=4x+7-4x

0=7

No solution as this is false.

Write the quadratic equation y=x^2-6+7 in vertex form
antoniya [11.8K]
Half the x-coefficient is -3, so the equation needs to be rearranged into a form that looks like
  x² -6x +(-3)² + [something]
You can get there by adding and subtracting 9 from the original equation.
  y = x² -6x +9 +7 -9 . . . . . 9 added and subtracted
  y = (x² -6x +9) -2
The quantity in parentheses is a perfect square, so we can write the equation in the desired form as ...
  y = (x -3)² -2

If a phone charges 3% every five minutes then how long will it take for the phone to charge 100%
postnew [5]

To find out how long it will take a phone to charge 100% if it charges 3% every 5 minutes, you have to put it in a fraction.

3/5

3 is the percent charged and 5 is the time.

You have to find out what 100 divided by 3 is. The answer is 33.3.

So,

3/5 times 33.3 is equal to 99.9/166.5.

It will take 166.5 minutes for the phone to charge to about 100%.

hope it helps.

can you choose mine as the brainliest answer
