Answer:
x=125º
2x=250º
Step-by-step explanation:
720 is the sum of the interior angles of a Hexagon
720=60+65+120+100+3x
720=345 +3x
-3x=345-720
-3x=-375
-x=-125
x=125
No because if you plug in 4 for x and 5 for y you get -4 not 36
Answer:
21x²
Step-by-step explanation:
hopefully A is a typo
Answer:
the slope increases
Step-by-step explanation:
Write a new equation using the new y-intercept and same slope as the original equation. Analysis: What effect does changing the y-intercept of an equation have on the graph? Increasing a y-intercepts moves the graph up. Decreasing a y-intercept moves the graph down.
Answer:
3
Step-by-step explanation:
A + B is calculated by adding the same positions in both matrices.
and position (2, 3) in A+B is therefore the sum of position (2, 3) in A plus the position (2, 3) in B, which is then
-4 + 7 = 3
