Write an equation for the line parallel to the given line that contains C<br> C(2,6); y= -4x + 7

MrRa [10]

Answer:

$y=-4x+14$

Step-by-step explanation:

step 1

Find the slope of the given line

we have

$y=-4x+7$

This is the equation of the given line in slope intercept form

The slope is $m=-4$

step 2

Find the slope of the line parallel to the given line

we know that

If two lines are parallel, then their slopes are the same

therefore

The slope of the line parallel to to the given line is $m=-4$

step 3

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=-4$

$C\ (2,6)$

substitute

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

step 4

Convert to slope intercept form

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

isolate the variable y

$y-6=-4x+8$

$y=-4x+8+6$

$y=-4x+14$

Cindy and her friends ate 3/5 a tray of cookies, if she took 1/2 of the remaining cookies to school the next day what fraction o

AleksAgata [21]

Hello the answer would be 3/10. because when a math question has of in it, ("1/2 OF") means its multiplication most of the time so then you do 3/5 ÷ 1/2 YOU CAN CONVERT THE DIVISION SYMBOL by using KEEP CHANGE FLIP. and change the equation to 3/5 × 2/2 and get 6/10 and took 3/10 so 3/10 6/10=3/10. hope I could help

Exactly one of the numbers 2,3 5 and 7 is placed in each of the 4 empty regions formed by circles A, B and C so that the sum of

Schach [20]

Answer:

The sum of the numbers in each circle is 17

Step-by-step explanation:

The numbers to choose from are:

2, 3, 5, 7

By this alone the biggest number must be in the overlap of the three circles.

Then just fill in the numbers in such a way that they all are used.

The sum of the numbers in each circle is 17.

See picture for a solution.
