Pls help find the answers for question 6

m1= 128 m2= 52 m3= 47 m4= 133 m5= 81

Step-by-step explanation:

A line is = 180. Angle 5 is sharing the line with the degrees 52 and 47. 52 + 47 = 99. 180 - 99 = 81. I believe that angle 3 and 47 are equivalent and that angle 2 and 52 are equivalent. I'm sorry if I'm wrong. You need angle 2 for angle 1. 180 - 52 = 128. You also need angle 3 for angle 4. 180 - 47 = 133. Hopefully this helps.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
