Answer:
G
Step-by-step explanation:
Distribute the -7 to 4x and -5
Answer:
x = -6
Step-by-step explanation:
B = 2
F = 6
D = 4
H = 8
x + B = Fx - Dx + H
x + 2 = 6x - 4x + 8
x + 2 = 2x + 8
-x = 6
x = -6
Answer:
B
Step-by-step explanation:
9 multiple 2m = 18m
9 multiple 5n = 45n
9 multiple 10= 90
Answer should be 525.
Work:
Divide the 350 by the 2 parts from 2/3 you should get 175.
The number 175 represents 1/3 so all you have to do now is add 350 by 175.
Given y=6-[sqrt(4-3x)], focus on the sqrt function: sqrt(4-3x). Since the input of this function cannot be negative, any x-value used must pass the test 4-3x>0. This is equivalent to 4>3x, or 3x<4, or x < 4/3. This eliminates choice E.
Second, if the y value is an integer, then sqrt(4-3x) must be an integer.
Checking answers A through D:
A: sqrt(4-3) = sqrt(1) = 1 (OK) Then y=6-[sqrt(1)] = 5 (NO)
B: sqrt(4-0) = 2 (OK) Then y=6-2 = 4 (NO)
C: sqrt(4-0) = 2 (OK) Then y=6-2 = 4 (NO)
D: sqrt(4-15) Not OK; eliminate
Correct answer: F: None of the above answers are correct
