Which equation is the slope-intercept form of the line that passes through (6, –11) and is parallel to the graph of y = –23x + 1
Finger [1]

Answer:

Equation of other line passing through point (6 , - 11) and parallel to given line is  y = - 23 x + 127 .

Step-by-step explanation:

Given as :

The equation of one line

y = - 23 x + 12

∵ The equation of line in slope-intercept form is

y = m x + c

where m is the slope of line and c is y-intercept

Now, Compare given line with standard line equation

So, The slope of given line = m = - 23

Now, Again

Other line is passing through point (6 , - 11) and is parallel to given line

so, both the lines are parallel

For parallel line condition , Slope of both lines are equal

Let The slope of other line = M

So, M = m = - 23

Now, Equation of other line passing through point (6 , - 11) and slope - 23 in slope-point form

y - y_1 = M × (x -  x_1)

i.e y - ( - 11) = (- 23) × (x - 6)

Or, y + 11 = - 23 × x + 138

Or, y = - 23 x + 138- 11

i.e y = - 23 x + 127

So, The equation of other line  y = - 23 x + 127

Hence, Equation of other line passing through point (6 , - 11) and parallel to given line is  y = - 23 x + 127 . Answer

What is the measure of def
pav-90 [236]

Answer:

answer is 107 degrees

Step-by-step explanation:

Given is a picture of triangle with vertices D, E and F

Given that exterior angle of F = 135 degrees

Hence interior angle of F =180-135=45 degrees

Angle D = 28 degrees

Hence angle E =

180-(28+45)\\=107

Hence answer is 107 degrees

Can someone please answer these questions?
andrew11 [14]

5.a) since the distance is 140km, and the time is 2hours, and we need the speed in km/h,  we have to divide the distance by time, and we will get the speed: s=d/t = 140km/2h = 70km/h

b) the distance is 43km, and the time is 30 minutes, which is 0,5hours, we do the same thing here, with given formula : s=d/t = 43km/0,5h = 86km/h

If f(x) = 3x + 10x and g(x) = 4x - 2, find (f - g)(x).
Anika [276]

Answer:

(f-g)(x)=9x+2

Step-by-step explanation:

The function  (f-g)(x) means subtract the expression of g function from the expression of f function.

So we have:  (3x+10x) - (4x - 2) = (13x) - (4x -2) = 13x -4x +2 = 9x+2

Hence  (f-g)(x)=9x+2
