Answer:
f(x) = 30 • 0.989x
Step-by-step explanation:
Given the data :
10 26.8
20 23.9
30 21.3
40 19
50 16.9
60 15.1
Using technology, the exponential model equation obtained by plotting the data is :
y = 30.068(0.989)^x
Based on the general exponential formula :
y = ab^x
y = predicted value
Initial value, a = 30.068
Rate = b = 0.989
The most appropriate model equation from the options given is :
f(x) = 30 • 0.989^x
Answer:
z = 11
Explanation:
5y + 13 = 6y
Subtract 5y by both sides.
13 = y
Next,
z + 22 = 3z
Subtract z by both sides.
22 = 2z
Then, divide both sides by 2.
11 = z
Finally plug those answers into the equations.
5(13) + 13 = 78
6(13) = 78
(11) + 22 = 33
3(11) = 33
So △DEF ≅ △JKI because the value of z = 11.
420 is the least common multiple for 21, 28, 35
Answer:
19y+5
Step-by-step explanation:
Combine like terms look for all the numbers that have y attached and combine them
7y +12y=19y
Look for terms where nothing is attached it's just the number combine them
6-1=5
Put all together again and you get:
19y+5
Answer:
Step-by-step explanation:
y + 4 = -8(x - 2)
I dont know the statements that u have but maybe I can guess one...or two
slope = -8
points used were : (2,-4)
y + 4 = -8(x - 2)
y + 4 = -8x + 16
y = -8x + 16 - 4
y = -8x + 12 ............slope intercept form
8x + y = 12 .......standard form
x intercept = (3/2,0)
y intercept = (0,12)
any of that answer ur question ?
