Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
= (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 6, 3) and (x₂, y₂ ) = (1, 5)
m = 
=
Answer:
x^2 + 10x - 13y.
Step-by-step explanation:
3(2x + y) + 4(x - 4y) + x^2 First apply the Distributive law to the parentheses:
= 6x + 3y + 4x - 16y + x^2 Now add like terms:
= 10x - 13y + x^2.
Answer:
Step-by-step explanation:
Pay attention to order of vertices when comparing the congruent parts or figures.
C and D as well as B and E are corresponding vertices according to angle marks and side marks.
32
Sorry, I couldn't really think of a way to explain but the best I can is by multiplying the 4 by 8 to get the answer of 32
