-Dominant- [34]

Answer:

(0, - 11 )

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 )

y = 3x - 11 ← is in slope- intercept form

with c = - 11 ⇒ (0, - 11 ) ← coordinates of y- intercept

Answer:

A. Definition of linear pair

Step-by-step explanation:

A linear pair of angles is formed when two lines intersect. Since angle on a straight line = 180°, angles of a linear pair sum up to 180°.

angles 1 and 4, angles 2 and 5, angles 3 and 6 are all linear pairs. Each pair = 180°.

posledela

Answer:+3i or -3i

Step-by-step explanation:

±√(-36)=+√(-36) or -√(-36)

+√(-1)×√(36) or -√(-1)×√(36) √(-1)=i

+i×6 or -i×6=+6i or -6i

Dividing by 2 we get

+6i/2 or -6i/2=+3i or -3i

Use the order of operations to simplify this expression.
dedylja [7]
The order of operations is PEMDAS which is Parentheses, Exponents, Multiplication/Division, and Addition/Subtraction. So, since there are no parentheses or exponents, we would do multiplication first. 3.5x4.1 is 14.35. So, the new equation is 1.2+14.35. This equals 15.55, which is answer choice B. Hope this helps!
