2x-3y=6 How do you get y by itself
Answers
Answer:
[tex]y=\frac{2x-6}{3}[/tex]
Step-by-step explanation:
3y=2x-6
[tex]y=\frac{2x-6}{3}[/tex]
First, you have to move the x, along with the coefficient(2).
To move the 2x, you have to subtract it from both sides.
So you have -3y= 6-2x
Now you have to divide by -3.
DON’T FORGET THE NEGATIVE.
So you have y = -2 +2/3
In slope intercept form

HELP PLEASEE!!!! ASAP which of the following is the slope of any line perpendicular to the line with equation 2x + y - 3 = 0
Answers
Answer:
m perpendicular = −3 / 2
Step-by-step explanation:
y = m x+b
where m represents the slope and b, the y-intercept.
−3 y = −2 x + 5
divide all terms by - 3
−3 y − 3 = − 2 − 3 x + 5 − 3
y = 23 x − 53
in slope-intercept form
slope = m = 23
The slope of a perpendicular line is the
negative reciprocal of m

8c + 20 = -180
c =
can some one help me please
Answers
Answer:
c = -25
Step-by-step explanation:
8c + 120 = -180
Subtract 20 from both sides.
8c = -200
Divide both sides by 8.
c = -25
Answer:
C = -25
Step-by-step explanation:
Start by getting C alone, subtract 20 from the left side of the equal sign and subtract 20 from the right. (what you do on one side you MUST do to the other) this gives you 8c= -200. Divide 8 from 8c on the right side and divide 8 from -200 on the left side. This will give you c= -25

the function is x^2-9, so all you have to do is replace x with a number. for example, 2.
so 2^2-9 is -5. the plot would be 2, -5. basically, plug in a number to be the x coord, and whatever number you get will be your y coord.
after you graph a few plots (doing the same thing above), draw a line through all of them.
if the line goes up towards the right top corner, it's increasing. if it goes down the right bottom corner, it's decreasing.
The value of a machine worth 45,000 rupees is decreasing at the rate of 20% per annum. Find the total reduction after 2 years?
Answers
Answer:
Total reduction after 2 years = [tex]16,200[/tex] rupees
Step-by-step explanation:
Current price of a machine [tex](P_0)[/tex] = 45,000 rupees
Rate of depreciation (r) = 20%
Time (t) = 2 years
Price after 2 years = [tex]P_0(1-\frac{r}{100} )^t[/tex]
[tex]=45000(1-\frac{20}{100})^2 \\=45000(1-\frac{1}{5})^2\\ =45000(\frac{4}{5})^2\\ =45000(\frac{16}{25})[/tex]
[tex]=28800\,\,[/tex] rupees
Total reduction after 2 years = [tex]P-P_0=45,000-28,800=16,200[/tex] rupees
1890s was rounded to the nearest 10 what is the upper bound
Answers
Answer:
When rounding to the nearest ten, like we did with 1890 above, we use the following rules:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
