Work out the m and c for the line<br> y=x+6
VARVARA [1.3K]

Answer:

m - 1

c - 6

Step-by-step explanation:

y=x+6\\\\

The equation is in slope-intercept form.

y = mx + c

m - slope

c (or b) - y -intercept

Usually if the slope is one it will not be written.

y = 1x + 6  

The slope is one.

6 takes 'c's place, so it is the y-intercept.

Hope this helps.

Henry charged $847 to his credit card . The card the cost of his next purchase caused him to go over his credit limit of $1000.
Mama L [17]

Answer:

(x-2 )( x + 1) = (-2 - c)

Step-by-step explanation:

C= - 1 = -x

We cna either multiply x and c until we find HCM before imputing x value and c value that is unknown variable.

To find that we can say x = the average of 1000 + $800 = $900 and work out the difference between the two.

We can use a new variable for half that difference to ensure we add or subtract to find the value 1000 or -1000 again.

So that $1000 - $847 = $153 half this difference is 2/3y so that 4/3 = $153 and 1/3 = 33.333 as we are working with 3 numbers then 1/3 or 2/3 for example could show a debit;

Balance of each 1000 would look like

2/3y + x + c

= c + xy - y1/3  

to show smaller amounts for the last 2 debits.
