Answer:
4th choice: I and IV only
Step-by-step explanation:
Change the form of the given equation to standard form.
y = -2/3 x + 2
3y = -2x + 6
2x + 3y = 6
Now compare this equation with the 4 choices.
Any equation that has the same x- and y-terms but a different constant term is parallel.
I. is parallel.
II. and III. are not parallel.
Look at IV.:
4x + 6y = 3
Divide both sides by 2:
2x + 3y = 3/2
IV. is also parallel.
Answer: 4th choice: I and IV only
A) 45 because 1350 divide by 30 equals 45. So 45 dollars u can afford
B) 1350 because 45 x 30 = 1350
C) 7% because it’s 7% to begin with
Answer:
x = 5
Step-by-step explanation:
6x - 3 = 3x + 12
-3x -3x
_____________
3x - 3 = 12
+3 +3
_____________
3x = 15
15 divided by 3 = 5
x = 5
You can double check this by replacing x with (5)
If it is right both sides should equal the same
6(5) - 3 = 3(5) + 12
30 - 3 = 15 + 12
27 = 27
This would prove that x = 5
Answer:
64
Step-by-step explanation:
To complete the square
add ( half the coefficient of the b- term )² to b² + 16b
b² + 2(8)b + 8²
= b² + 16b + 64 = (b + 8)²
Answer:
11/25
Step-by-step explanation:
# means number
probability = # of orange marbles / # of total possible outcomes
7(red) + 3(green) + 4(blue) + 11(orange) = total possible outcomes
total possible outcomes = 25
# of orange marbles = 11
11/25; the probabilty of randomling picking an orange marble is 11/25
