a line is paralll yo y=4x-2 and intersects the point (5,-11). what is the equation of this parallel line
victus00 [196]

The equation of line parallel to given line is: y=4x-31

Step-by-step explanation:

Given equation of line is:

y = 4x-2

The equation of line is in slope-intercept form so the co-efficient of x is the slope of the line.

Let m1 be the slope of the given line

then

m1 = 4

Let m2 be the line that is parallel to given line

As we know that the slopes of parallel lines is equal so

m1=m2 = 4

The slope-intercept form of equation of line is:

y = m_2x+b

Putting the value of slope

y = 4x+b

to find the value of b, putting (5,-11) in the equation

-11 = 4(5) + b\\-11 = 20+b\\b = -11-20\\b = -31

Putting the value of b

y=4x-31

Hence,

The equation of line parallel to given line is: y=4x-31

Keywords: Equation of line, slope

BRO PLEASE HELP ME IM BEGGING YOU <br><br> Find the perimeter. Simplify your answer
Ostrovityanka [42]

Answer:

22s - 9

Step-by-step explanation:

The perimeter (P) is the sum of the 4 sides , that is

P = 2s + 7 + 9s - 5 + 6s - 10 + 5s - 1 ( collect like terms )

  = (2s + 9s + 6s + 5s) + (7 - 5 - 10 - 1)

  = 22s + (- 9)

 = 22s - 9

Can someone help me I’m a little lost
Ksivusya [100]

Answer:

14 days

Step-by-step explanation:

Total Problems = 175

Finished Problems = 8

Remaining = 175 - 8 = 167

8 problems in 30 minutes, means:

30/8 = 15/4 = 3.75 minutes per problem

If he works for 45 minutes, at that rate, he can solve:

45/3.75 = 12 problems per day

To finish 167 problems, he will need:

167/12 = 13.91

Rounded, that is <u>14 days more to finish</u>
