Which equation represents a line parallel to the line whose equations is -2x + 3y =
-4 and passes through the point (1,3)?
Answers
Answer:
2. y - 3 = 2/3 (x - 1).
Step-by-step explanation:
-2x + 3y = -4
3y = 2x - 4
y = 2/3 x - 4/3 - so the slope is 2/3.
The slope of a line parallel to it is also 2/3.
It also passes through the point (1, 3).
Using the point-slope form of a line:
y - y1 = m(x - x1) where m = the slope and (x1, y1) is a point on the line, we have:
y - 3 = 2/3 (x - 1) <--- is the required equation.
Answer:
2
Step-by-step explanation:
parallel lines have same slope with different intercept
y= mx+b
m is going to be same with different b
so the given function is:
-2x+3y=-43y= 2x-4y= 2/3x - 4/3Given options:
1. y-3= - 2/3(x-1) ⇒ y= -2/3x +3 + 2/3 ⇒ y= -2/3x +11/3
it has different slope, so is not parallel2. y-3= 2/3(x-1) ⇒ y= 2/3x+3-2/3 ⇒ y= 2/3x + 7/3
it has same slope, so is parallelit should be passing through point (1,3)3= 2/3+7/3 ⇒ 3=3, yes it does3. y-3= -2/3(x+1) ⇒ y= - 2/3x +3- 2/3 ⇒ y= -2/3x + 7/3
it has different slope, is not parallel4. y-3= 2/3(x+1) ⇒ y= 2/3x +3+ 2/3 ⇒ y= 2/3x +11/3
it has same slope, so is parallelit should be passing through point (1,3)3= 2/3+11/3 ⇒ 3≠13/3, no it doesn'tRelated Questions

Answers
Answer:
x=21978/35
Step-by-step explanation:
Steps:
1: Step 1: Simplify both sides of the equation
241 14 + 83 7 = x 11 9 (55) 12 241 14 + 83 7 = 5 108 x ( 241 14 + 83 7 )= 5 108 x(Combine Like Terms) 407 14 = 5 108 x 407 14 = 5 108 x
2: Step 2: Flip the equation
5/108x=407/14
3: Step 3: Multiply both sides by 108/5.
(1085)*(5108x)=(1085)*(40714)

Must find the slope of the hill
Answers
Answer: Option no. C 486/11
The requried slope of the hill which is 11 yd tall and 486 yd long is 11/486. Option D is correct.
To find the slope of a hill, we can use the formula: slope = rise/run.
In this case, the rise refers to the vertical change, which is the height of the hill, given as 11 yd. The run refers to the horizontal change, which is the length of the hill, given as 486 yd.
Using the formula, we can calculate the slope:
slope = rise/run
slope = 11 yd / 486 yd
To simplify the slope, we can divide both the numerator and the denominator by the greatest common divisor, which is 1 in this case:
slope = 11 / 486
Therefore, the slope of the hill is 11/486.

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)
Answers
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.

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.
Answers
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
Answers
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
