Consider the statement "Two lines in a coordinate plane are parallel if and only if the slopes of the lines are m and m, where m is any real number." Is this statement true or false? Explain your reasoning.
Statement is true.
The slopes of parallel lines are equal. Note that two lines are parallel if their slopes are equal and they have different y-intercepts.
Their:
1. corresponding angles are equal.
2. Alternative interior angles are equal.
3. Consecutive interior angles are supplementary.
4. Consecutive exterior angles are supplementary.

In an electrical circuit, the current is related to the power and resistance according to the rule I=pR−−√, where I represents the current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms). What is the electrical power drawn by a device that has a resistance of 15 ohms with a current of 4 amps?
Answer:
[tex]P=0.27\,\,watts[/tex]
Step-by-step explanation:
Consider the formula: [tex]I=PR[/tex]
Here, [tex]I[/tex] represents the current (measured in amps), P represents power (measured in watts), and R represents resistance (measured in ohms).
Resistance = 15 ohms
Current = 4 amps
To find electrical power drawn by a device, put [tex]R=15\,,\,I=4[/tex]
So,
[tex]4=15P\\P=\frac{4}{15}=0.27\,\,watts[/tex]

slope of a line passing through points A (3, 2) and B (-2, -3)?
Answer:
1
Step-by-step explanation:
So for this type of problem we use the formula [tex]m= \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] with each variable (besides m which is slope) representing a different coordinate. (e.g. -3 could be [tex]y_{2}[/tex] in this case.) First, let's define which is which:
(3,2): [tex]x_{1}, y_{1}[/tex]
(-2,-3): [tex]x_{2}, y_{2}[/tex]
Now we need to replace the variables with their known values: [tex]m=\frac{-3-2}{-2-3}[/tex]
Next, let's do the subtraction to simplify: [tex]m=\frac{-5}{-5}[/tex]
And we can complete the division (all fractions are division!) to simplify even further: [tex]m = 1[/tex]
Therefore, the slope of the line passing through the points (3,2) and (-2,-3) is 1.

Can somebody help me with this?
Step-by-step explanation:
Hey there!
By looking through figure, l and m are parallel lines and a transversal line passes through the lines.
Now,
7x + 12° = 12x - 28°( alternate angles are equal)
12°+28° = 12x - 7x
40° = 5x
[tex]x = \frac{40}{5} [/tex]
Therefore, x = 8°
Now,
12x - 28° + 9y - 77 = 180° ( being linear pair)
12×8° - 28° + 9y -77° = 180°
96° - 28° + 9y - 77° = 180°
-9 + 9y = 180°
9y = 180° + 9°
y = 189°/9
Therefore, y = 21°
Therefore, X = 8° and y= 21° .

A grocery store sells a bag of 6 oranges for $4.20. If Ayden spent $2.80 on oranges, how many did he buy?
Answer:
4 bags of oranges
Step-by-step explanation:
First, we need to find out how much each bag of oranges costs so we divide.
$4.20 divided by 6 equals 0.7 which means that each bag of oranges costs $0.70.
Next we need to find out how much Ayden spent on oranges so we divide 0.70 by 2.80
2.80 divided by 0.70 equals 4.
This means that Ayden bought 4 bags of oranges.
Hope this helps!
Answer:
4 oranges
Step-by-step explanation:
First find the unit rate by dividing the price of 6 oranges by the amount of oranges in the bag. So $4.20÷6=0.7. 0.7 is the price of one orange. Since the dollar amount is small I just divided $4.20 by 2 and got $2.10 for three oranges. The question is asking how much he bought for $2.80 so add another .70 which is one more orange therefore he bought 4 oranges for $2.80

Answer:
m=0.833333
Step-by-step explanation:
(1/16)−3m+1=64
log((1/16)−3m+1)=log(64)
(Take log of both sides)
(−3m+1)*(log(1/16))=log(64)
−3m+1=log(64)
log(1/16)
−3m+1=−1.5
−3m+1−1=−1.5−1
(Subtract 1 from both sides)
−3m=−2.5
−3m
−3
=
−2.5
−3
(Divide both sides by -3)

What is an equation of the line that passes through the point
(−6,5) and is parallel to the line x−3y=21?
Step-by-step explanation:
Parallel lines have the same slope.
x -3y = 21
y = (21-x)/-3 ==== y = 1/3x -7
Substitute the values,
y = mx + c
5 = (1/3)(-6) + c
5 = -2 + c
c = 7
Thus, the equation is y = 1/3x + 7
An equation of the line that passes through the point (−6,5) and is parallel to the line x−3y=21 is y = 1/3x + 7.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
We need to find an equation of the line that passes through the point (−6,5) and is parallel to the line x−3y=21.
Parallel lines have the same slope;
x -3y = 21
y = (21-x)/-3
y = 1/3x -7
Substitute the values;
y = mx + c
5 = (1/3)(-6) + c
5 = -2 + c
c = 7
Therefore, the equation is y = 1/3x + 7

A(n)=2+(n-1)(3) find the fourth and tenth term of the sequence
Answer:
The fourth term is 11 and the tenth term is 29
Step-by-step explanation:
Let us use the given formula to solve the question
∵ A(n) = 2 + (n - 1)(3) is the formula of the nth term of an sequence
∵ n is the position of the term in the sequence
∴ For the fourth term n = 4
∴ For the tenth term n = 10
→ Substitute n by 4 in the formula above to find the fourth term
∵ A(4) = 2 + (4 - 1)(3)
∴ A(4) = 2 + (3)(3)
∴ A(4) = 2 + 9
∴ A(4) = 11
∴ The fourth term is 11
→ For the tenth term put n = 10
∵ n = 10
∵ A(10) = 2 + (10 - 1)(3)
∴ A(10) = 2 + (9)(3)
∴ A(10) = 2 + 27
∴ A(10) = 29
∴ The tenth term is 29
