Answer:
false
Step-by-step explanation:
X is equal to Y
therefore,
X = Y
X= false
Y = false
so,
false = false
Answer:
Step-by-step explanation:
Given: 39 = 0.01n
Move the decimal point on each side two places to the right: 3900 = n
X + 4y = 3 x = -4y + 3
2x - 3y = 17
2(-4y + 3) - 3y = 17
-8y + 6 - 3y = 17
-11y + 6 = 17
-11y = 11
y = -1
x = -4(-1) + 3
x = 4 + 3
x = 7
(7, -1) is your answer
Answer:
If the line goes through the origin, (0,0), that means the linear equation is proportional, if it doesn't go through the origin, the equation isn't proportional.
You can also tell if a linear equation is proportional if the equation has an constant after the x (for example y=2x+6)
Answer:
The answer top your question is: 1/2, 3/2, 5/2 and 7/2
Step-by-step explanation:
Data
4 consecutive numbers that add up to 8
First number = n
2nd number = n + 1
3rd number = n + 2
4th number = n + 3
Now, add them up n + n + 1 + n + 2 + n + 3 = 8
Simplify like terms
4n + 6 = 8
4n = 8 - 6
4n = 2
n = 2/4 = 1/2
First number = n = 1/2
2nd number = n + 1 = 1/2 + 1 = 3/2
3rd number = n + 2 = 1/2 + 2 = 5/2
4th number = n + 3 = 1/2 + 3 = 7/2
