Mathematics

Answer:

B 45 degrees

Step-by-step explanation:

if AB and CA are = the M2 = 90 degrees

in an right triangle ware one angle is 90 degrees and one is 45 degrees the outer one will be 45 degrees  

the total of the angles in a triangle is 180 degrees so 180 - 90 = 90

90 - 45 = 45

so the remaining angle is 45.

Use the slope of the given line to construct a parallel line
Troyanec [42]

Answer:

y = - \frac{4}{3} x - 7

Step-by-step explanation:

Parallel lines have equal slopes.

Calculate the slope m of the given line using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line

m = \frac{-2-2}{3-0} = - \frac{4}{3}, thus

y = - \frac{4}{3} x + c ← is the partial equation

To find c substitute P(- 3, - 3) into the partial equation

- 3 = 4 + c ⇒ c = - 3 - 4 = - 7

y = - \frac{4}{3} x - 7 ← equation of parallel line

X = -y-6<br> 7x + 6y = –10
Ede4ka [16]

Answer:

[26, -32]

Step-by-step explanation:

7[-y - 6] + 6y = -10

-7y - 42 + 6y = -10

-y - 42 = -10

+ 42 + 42

____________

-y = 32

-32 = y [Plug this back into both equations to get the x-value of 26]; 26 = x

Find the equation of the line that goes through ( 2, 4 ) and ( 4, 6 ).
Mrrafil [7]

Answer:

y=x+2

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(6-4)/(4-2)

m=2/2

m=1

y-y1=m(x-x1)

y-4=1(x-2)

y=x-2+4

y=x+2
