Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = , thus
y = x + c ← is the partial equation
To find c substitute (- 4, - 9) into the partial equation
- 9 = - 2 + c ⇒ c = - 9 + 2 = - 7
y = x - 7 ← equation of line
Answer:
Step-by-step explanation:
so for the triangles in 7) they angles are the same in each, that's what the lines are saying, that they are the same angles, and because the angle are the same, the triangles are just a scale of each other we can say that the X side is just a ratio of the other triangle , or
=
now just solve for X
*
=
*
x = 120/6
x=20
_______________________________
for the triangles in 8) same thing
=
*
=
*
X =
X = 2
Answer:
45
Step-by-step explanation:
We make a proportion and solve it:
28 x = 20x+360
8x=360
x=45
