Answer:
2x^2
Step-by-step explanation:
combine like terms, and do the subtraction!
Answer:
y = 4x -19
Step-by-step explanation:
y = 4x + b
first we add the point to the equation and then we solve for b
-3 = 4 ( 4 ) + b
-3 = 16 + b
-16
-19 = b
Answer:
(9)(m)
Step By Step Explanation:
9m is multiplying. So you need to find the one that deals with multiplication.
m-9 is subtraction
9/m is division
9+m is addition
(9)(m) is multiplication
Hope this helps :)
Answer:
Step-by-step explanation:
Alternate angles are angles that are opposite, on the other side of the lines, so imagine it as a z shape.
In this case, alternate angles include, 3, 13, other equal angles are vertically opposite, so that would include 7, 1, 15. Vertically opposite angles that are two angles made opposite with 2 intersecting lines.

Answer:
Step-by-step explanation:
To find measures of angles m and n
The triangle to the left has three sides of equal length.
This means that it will also have three angles of equal measure.
The internal angles of a triangle sum to 180°
So the internal angles of the left triangle are 180/3 = 60°
The top right angle is made up of one of the 60° angles and angle n
60 + n = 90
n = 30°
Again the internal angles of a triangle sum to 180°, so the right triangle
m + n + 90 = 180
m = 180 - 90 - 30
m = 60°
or we could realize that the top and bottom horizontal lines are parallel because the vertical line on the right makes right angles to both of them.
Knowing that they are parallel, we also know that angle m and the top right 60° angle of the left triangle are opposite internal angles of a line intersecting parallel lines and must be identical angles, therefore
m = 60°
