Answer:
-0.25y
Step-by-step explanation:
Simplifying
4x + 1y = 12
Solving
4x + 1y = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1y' to each side of the equation.
4x + 1y + -1y = 12 + -1y
Combine like terms: 1y + -1y = 0
4x + 0 = 12 + -1y
4x = 12 + -1y
Divide each side by '4'.
x = 3 + -0.25y
Simplifying
x = 3 + -0.25y
Answer:
x = 3 + -0.25y
Step-by-step explanation: Simplifying:4x + 1y = 12Solving:4x + 1y = 12Solving for variable 'x'.:Move all terms containing x to the left, all other terms to the right.Add '-1y' to each side of the equation.4x + 1y + -1y = 12 + -1yCombine like terms: 1y + -1y = 04x + 0 = 12 + -1y4x = 12 + -1yDivide each side by '4'.x = 3 + -0.25ySimplifyingx = 3 + -0.25y|x|=3

Answer:
x = -3, x = 3
Step-by-step explanation:
The answer of an abosulte value is always positive. So, when you put a positive number in an absolute value, you will get a positive value (in this case 3). Also, you have to put the negative number in an absolute value (in this case -3).

How many seconds did It take the plece of paper to reach the ground?
Record your answer and fill in the bubbles on your answer document.
Answer:
12 seconds
Step-by-step explanation:
Given
[tex]y = -2.5x + 30[/tex]
Required
Determine the time taken to reach the ground
For the paper to reach the ground, y = 0
So, we have:
[tex]y = -2.5x + 30[/tex]
[tex]0 = -2.5x + 30[/tex]
Collect Like Terms
[tex]2.5x +0 = 30[/tex]
[tex]2.5x = 30[/tex]
Divide through by 2.5
[tex]2.5x/2.5 = 30/2.5[/tex]
[tex]x = 30/2.5[/tex]
[tex]x = 12[/tex]
Hence:
Time taken is 12 seconds

12 -4x = -8x wat i s te answer to tis
Answer:
-3 =x
Step-by-step explanation:
12 -4x = -8x
Add 4x to each side
12 -4x+4x = -8x+4x
12 = -4x
Divide each side by -4
12/-4 = -4x/-4
-3 =x
Factor completely 36x^4y^4z^4 – 20x^8y
Please factor this for me
Answer:
4x^4y(9y^3z^4 -5x^4)
Step-by-step explanation:
The two terms have a common factor of 4x^4y, so we can rewrite the expression as ...
= 4x^4y(9y^3z^4 -5x^4)

Passing through (-7, -3) and parallel to the line whose equation is y = - 4x + 1
write in point slope form
Answer:
The answer is
y = - 4x - 31Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
From the question the original line is
y = - 4x + 1
Comparing with the general equation above
Slope / m = - 4
Since the lines are parallel their slope are also the same
Slope of parallel line = - 4
So the equation of the line using point
(-7, -3) is
[tex]y + 3 = - 4(x + 7) \\ y + 3 = - 4x - 28 \\ y = - 4x - 28 - 3[/tex]
We have the final answer as
y = - 4x - 31Hope this helps you

Hundred tens one
The question is asking for to round to the nearest hundred (100) which means is rounding to [9] in this question.
The number of the place before the hundreds place is [8] on the tens place.
When numbers are greater than or equal to 5, you round up a digit.When numbers are less than 5, you round down a digit.[8] is greater than 5, so you round 9 up. When rounding 9 up, you get 10.
So, the final number will be 1000Apex Learning answer is Syllogism

Jim will be x years old in two years. At that time, his sister will be twice as old as he will be. How old is Jim's sister now?
Pleaseee help.
Answer:
Jim's sister age now is ( 2x - 2) years.
Step-by-step explanation:
Given
Jim will be x years old in two years
At that time, his sister will be twice as old as he will be
Thus, the age of sister in two years = 2*Jim's age in 2 years
the age of sister in two years = 2*x years = 2x years
Jim's sister age now will be 2 years lesser than the age found above which is her age after two year
Jim's sister age now = age of sister in two years - 2 years
Jim's sister age now = 2x years - 2 years
Jim's sister age now = ( 2x - 2) years

A man is 26 years older than his son. After 10 years he will be 3 times as old as his son. Find their present ages.
The answer is: man=29 and son 3
I just need the steps
son = 3 years
man = 29 years
Step-by-step explanation:Hi there !
m = man
s = son
m = s + 26
m + 10 = 3(s + 10)
replace m
(s + 26) + 10 = 3s + 30
26 + 10 - 30 = 3s - s
2s = 6
s = 3 years (son)
m = 3 + 26 = 29 years (man)
