I used a calculator lol
Answer:
n = 0
Step-by-step explanation:
Multiply parenthesis by 3 and get:
1.) 18 + 9n = 5n + 18 + 3n
Then cancel the equal terms:
9n = 5n + 3n
Collect like terms:
9n = 8n
Move variable to the left:
9n - 8n = 0
n + 0
Plugin the value of 0 into x:
3 (6 + 3 x 0) = 18
5 x 0 + 3 x 0 + 18 = 18
*If the plugged in value have the same result than the answer is correct because 18 + 18.
Answer:
d
Step-by-step explanation:
all of the angles add up to equal 180 so we setup the equation as 45+3x=180
first you subtract each side by 45
135=3x
then you divide each side by 3 and get that
x=45
Answer:
D. Yes The Triangles ARE ≅
Step-by-step explanation:
By definition equilateral triangles have all equal angles and sides. Since they share a side that means one of each triangle's sides are congruent. Using the transitive property (if side a ≅ side b and side b ≅ side c, then side a ≅ side c), you can prove that all other sides are congruent or equal in measure, no matter how you pair them.
Answer:
-0.5
Step-by-step explanation:
The average rate of change from a to b:
[f(b) - f(a)]/(b - a)
Look in the graph for the function values at x = -3 and x = 0.
f(-3) = 2
f(0) = 0.5
average rate of change =
= [f(-3) - f(0)]/(-3 - 0)
= [2 - 0.5]/(-3)
= 1.5/(-3)
= -0.5
