Answer:
Step-by-step explanation:
option 1: x = 41
Reason:
<1 =139 { corresponding angles }
<2 = 180 - 139 = 41 ( <1 and <2 are linear pair}
x and <2 are corresponding angles.Hence x = 41
option 3 - <2 =<3 by vertical angles congruence
option 5 - <4 = <5by the alternate interior angles theorem
Answer:
-5+(√x-3) and -(√x-3)-5
Step-by-step explanation:
change f(x) to 'y' and then interchange x and y; then solve for y
y = x² + 10x + 28
x = y² + 10y + 28
you can use the Quadratic Formula to evaluate y² + 10y + 28 and will get:
-5+(√x-3) and -(√x-3)-5
Answer:
y = 3/2x - 4
Step-by-step explanation:
y = mx + b
*plugging in slope*
y = 3/2x + b
*finding b (aka y-intercept, starting value, when x=0) by plugging in x and y values from point (2, -1) )*
-1 = 3/2 * 2 + b
-1 = 3 + b
b = -4
so: y = 3/2x - 4
