Answer:
A. (0,4)
Step-by-step explanation:
You can calculate the y intercept when x = 0.
Substitute 0 for x:
y = (-4/3)(0) + 4
= 0 + 4
= 4
A) True. The domain of both is: x ≥ 0
B) True. 1/2 is on the outside so it is vertical. 1/2 is between 0 and 1 so it shrinks.
C) False. the coefficient is not 2 (it is 1/2)
D) False. 1/2 is not on the inside with "x" so it is not horizontal.
Answer: A, B
Hello there!
|a - b| - |c + d|
|-5 - 4| - |1 +(-3)|
=|-5 - 4| - |1 - 3|
= |-9| - |-2|
Solve for the absolute value
= 9 - 2
= 7
Answer:
See below
Step-by-step explanation:
13x + 5 + 17x - 4.5 + x
NOTE: You can only add/subtract LIKE terms . Here we have variable terms in x (13x , 17x and x) and 2 constants ( 5 and 4.5).
Sarah's next line is
18x + 17x - 4.5 + x
This is incorrect . It looks like she added 13x + 5 and got 18x!! Which is of course wrong because they are NOT LIKE terms. 5 is a constant and 13x is a variable term in x.
The third line is correct:-
35x - 4.5 + x.
She has added the 2 variables 17x and 18x.
Fourth line is 30.5x + x. She's at it again - Trying to subtract 4.5 from 35x .
Last line 31.5x
She has added the 2 terms in x correctly, but the final answer is wrong of course due to the earlier errors.
Answer:
x^2 = 36
Step-by-step explanation:
logx ( 36) = 2
Rewrite this as an exponential equation
We know that loga(b) =c as a^b =c
x^2 = 36
