Which graph represents 2x - 3y less than or equal to 9?
Answer:
answer is c
Step-by-step explanation:
Someone please help me with this question??
Examine the following table that represents some points on a line.
Which equations in point-slope form represents this line?
y + 10 = 2(x + 6)
y + 9 = 1/2(x + 4)
y + 10 = 1/2(x + 6)
y + 4 = 1/2(x — 6)
y + 4 = 2 (x — 6)
y — 9 = 2(x — 4)
Answer:
Option (2), (3) and (4)
Step-by-step explanation:
Let the equation of the line representing the given table is,
y - y' = m(x - x')
where 'm' = slope of the line
(x', y') is the point lying on the line.
Let the two points (-6, -10) and (-4, -9) lie on the line
Slope 'm' = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
= [tex]\frac{-9+10}{-4+6}[/tex]
= [tex]\frac{1}{2}[/tex]
Equation of the line passing through (-4, -9) with slope [tex]\frac{1}{2}[/tex] will be
y - (-9) = [tex]\frac{1}{2}(x+4)[/tex]
y + 9 = [tex]\frac{1}{2}(x+4)[/tex]
Equation of the line passing through (-6, -10) with slope = [tex]\frac{1}{2}[/tex]
y - (-10) = [tex]\frac{1}{2}(x+6)[/tex]
y + 10 = [tex]\frac{1}{2}(x+6)[/tex]
Equation of the line passing through (6, -4) and slope = [tex]\frac{1}{2}[/tex]
y + 4 = [tex]\frac{1}{2}(x-6)[/tex]
Therefore, Options (2), (3) and (4) will be the answer.
A line passes through (2,9) and has a zero slope

Work must be shown for this problem! The figure shown below is a rectangle. Make sure to solve for x and BD. Give both answers below.
Answer:
x = 10
BD = 74
Step-by-step explanation:
Find x by setting 3x+7 equal to 37. Solve for x by subtracting 7 on both sides then divide by 3 to get x=10.
Since 37 is half of AC, multiply that by 2 to find AC or BD, which are the exact same length of 74.
Answer:
x=10 and BD=74
Step-by-step explanation:
In a rectangle, the two parts of the diagonals are always equal to each other. This means that AE=CE=BE=ED.
So, if AE is 3x+7, this means DE and BE are also 3x+7, so BD is twice that, or 2(3x+7) which when you multiply it is 6x+14.
Oh, also, since it says CE=37, this means that 3x+7=37
3x+7=37
-7 -7
3x=30
x=10
Now that you know that BD is 6x+14, and x is 10, simply multiply it.
6(10)+14=BD
60+14=BD
74=BD

Which of the following steps indicates the addition property of equality while solving the equation –1 – 6x = x – 15? Question 4 options: A) x = 14∕2 B) –1 – 6x + 15 = x – 15 + 15 C) –1 – 6x = x – 15 D) 23 – 6x – 24 = x – 15
Answer:
B) -1-6 x +15 = x - 15 +15
Step-by-step explanation:
Explanation:-
Given equation is –1 – 6 x = x – 15
By addition property of equality
⇒ - 1 - 6 x + 15 = x - 15 +15
⇒ - 6 x + 14 = x
subtracting 'x' on both sides ,we get
⇒ - 6 x -x +14 =0
⇒ - 7 x +14 =0
⇒ -7 x = - 14
Dividing '-7' on both sides , we get
x = 2
The solution of given equation is x = 2
Answer:
-1-6x+15=x-15+15

As of mid-2016, the world's population was about 7.4 billion people. The population of the United States was 324 million.
The land area of a certain state is about 261,787 square miles. If in mid-2016 all of the world's people were put into that state, how many people would there be in each square mile? (Round your answer to the nearest whole number.)
Answer:
There would be approximately 28,267 per square mile.
Step-by-step explanation:
There are 7,400,000,000 people in the world. The state is 261,787 square miles.
7,400,000,000/261,787 = 28,267.2554 → 28,267
