Rates like $ per channel is a slope, "m". The added fee is a constant so it's the intercept "b".
y = mx + b
So for the first problem (9)
(a)
y = total cost in dollars
x = number of premium channels
y = 16x + 44
(b) when x = 3 channels
y = 16(3) + 44
y = 92 $
the second problem (10)
(a) every 4 years the tree grows by 12-9=3 ft
So the unit rate or slope will be 3 ft per 4 yrs, (3/4). You can see this also by solving for slope "m" using the given points (4,9) and (8,12).
x = number of years
y = height of tree in ft
y = (3/4)x + b
use one of the points to find the y-intercept "b".
9 = (3/4)(4) + b
9 = 3 + b
9 - 3 = b
6 = b
y = (3/4)x + 6
(b) when x = 16
y = (3/4)(16) + 6
y = 12 + 6
y = 18 ft
Answer:
No
Step-by-step explanation:
They are different because the base are the same but the exponents are different.
Answer:
This is a triangular prism
Step-by-step explanation:
Alright listen to the key words in the question specifically “CORRESPONDING” if u don’t know what corresponding means it means very similar or equivalent in comparison I will help u with the first 2 for u the corresponding Angle to a is angle x. ur basically looking for the same angle on 2 different triangles and the answer to angle b is angle z and if it’s 2 letters it means it one of the sides or lines to the triangle so line ab would be line xz on the other triangle I hope this helps
Answer:
58.55Kg
Step-by-step explanation:
450 in Kg is 0.45.
0.45 + 4.5 = 4.95. 4.95 + 53.6 = 58.55.
