Answer:
The method that is valid in finding the unit rate for a proportional relationship is by:
Look at the graph of the relationship. Count the number of units up and the number of units to the right one must move to arrive at the next point on the graph. Write these two numbers as a fraction. The unit rate is the slope, which is the rise over run.
Step-by-step explanation:
Answer:
B. Equilateral, and C. Acute.
Step-by-step explanation:
Scale factor for volume = A^3:B^3
(1:4)^3 = 1:64. The volume is 64x bigger.
Answer:
C
Step-by-step explanation:
In the table, we are given the points [ (-3, -5), (2, y), (5, 11), (8, 17) ]
We are given the equation [ f(x) = 2x + 1 ] where 2 = slope and 1 = y intercept.
We need to find the value of "y".
y2-y1/x2-x1
y-(-5)/2-(-3) = 2
y+5/5 = 2
y = 5
Best of Luck!
